See what our clients have to say about us.

““Clement windows have been our preferred supplier of steel frame windows and doors for some time and so we were thrilled to be able to showcase their W20 doors in our studio. Many of our clients like the concept of steel and glass partitions and doors for their home and it has proved really useful to have an example that they can see first-hand. We deliberately selected a softer colour than the widely used grey and black to inspire and open clients’ minds to an alternative colour suggestion. Clement were able to accommodate our request for a reeded glass finish. This assists us from a practical perspective in that it diffuses the view into our storage area, but adds a textural element to the screen too.”

Sutton Coldfield“I am thrilled to express my utmost satisfaction with the quality and service provided by Clement when they installed our new windows. The professionalism and attention to detail displayed by their team were truly exceptional. The windows have not only enhanced the aesthetics of our home but have also significantly improved energy efficiency. I highly recommend Clement to anyone seeking top-notch window solutions and impeccable customer service. Thank you for a job well done!”

Mrs Attwal

“Clement Windows have been incredible from start to finish. The quality of their products are superb and the windows often receive many compliments. Very impressed. I would highly recommend them to anyone.”

Sebastian Harris

"My contact with the installation and accounts teams has been uniformly warm and supportive, a particularly significant factor for me as an expat making arrangements remotely. Consequently, I can say that once our requirement had been communicated effectively, the rest of the project was handled most satisfactorily from my perspective. I look forward to the day when I can see the windows for myself instead of relying upon tenant reports.”

Tony Howells

India Building“We had the pleasure of working with Clement on the steel window replacements of the India Building refurbishment project. Their performance in every aspect of the work was outstanding, and we wholeheartedly endorse them for any future contracts of a similar nature. One specific area where Clement excelled during the early stages, was the support we received from them during our discussions with the city planners regarding the bespoke windows. Their contribution proved very useful in moving matters forward and the end result is exceptional.”

Alex Harrison
Associate, Falconer Chester Hall Architects

Brighton“I chose Clement because I wanted high quality slim profile metal sections in white that would look contemporary yet suit my Regency property. They were extremely helpful from start to finish and every step of the way. Their fitters were impressive and skilful and a pleasure to have in the house. I would highly recommend.”

Mary Weaver
Interiors Journalist

“Clement were brilliant from start to finish. Their professionalism and ability to work with the client to achieve the required end result within tight deadlines was very impressive. Highly recommended.”

Basel Shabsogh
Director, St Mary Abbots Court Limited

“I am absolutely delighted with Clement and would recommend them very highly. Their workmen were very professional and swift and they left the house tidy each day. They were a pleasure to have in the house whilst they were doing the work.”

Judith Bernstein

“We’ve worked with Clement Windows on several residential projects, this one being the most complex. The process from initial sketch design through to installation was excellent. Clement produced highly detailed drawings and were very responsive throughout the development of the design. The installation team worked in close collaboration with the Contractor and ensured all elements of the openings were prepared and ready for installation. The end result was an extremely high quality and complex product installed with very low tolerances to an impeccable standard.”

Children's playroom“I thoroughly enjoyed working with Clement Windows on this exciting project which was for a children’s playroom. I wanted to go with bold and bright colours and they were so accommodating about this, everything about the project was handled professionally and with utmost care from conception down to a flawless install. It was an absolute pleasure to work on such a personal project with a business I have collaborated with before and I look forward to hopefully crossing paths again in the future!”

Hannah Cecil-Harden
Director at de Gournay

St Mary’s Calne“The installation of 83 high quality Clement windows, which were installed in two phases during 2021 and 2022, have significantly enhanced the aesthetics and environmental efficiency of this building. Installation was very efficiently completed by Clement operatives within the specified installation timeframes.”

Bob Lunn
Director of Estates at St Mary’s Calne

Trent Young’s CE School“We are so pleased with the finished result! The transformation the windows have made to our school and local area is fantastic. Many local residents have also commented positively on the ‘new look’ windows. They have been sympathetically upgraded, in keeping with the original school building, and have had a positive impact on our school environment. Furthermore, there was no impact on the staff or the children during the refurbishment.”

Ros Baker
Deputy Head at Trent Young’s CE School

“Steel windows manufactured by Clement were the right choice because of their close match to the existing heritage windows at Ladywell Convent. The team at Clement did a great job. They delivered the project on time and there were no issues.”

Michael O’Brien
O&D Construction

St Paul’s Church, Ireland Wood, Leeds“We have worked with Clement on a number of projects and have been very pleased with the service we have received and the quality of their products. They supplied the steel framed glazed screen and feature window at St Paul’s Church, Ireland Wood, Leeds and we couldn’t have been happier with the result. We also specify Clement’s conservation rooflights whenever we can, as we are of the opinion that they are the best on the market.”

Tom Robbins
Pearce Bottomley Architects

"I came across Clement windows whilst on the hunt for an alternative to the usual standard rooflights. The conservation rooflights are just stunning and the black box frame adds a beautiful feature to the space, with the added bonus that I didn't have to paint them! I highly recommend them for any period project."

Lisa Brass

Whitchurch Town Council"The Town Council are really pleased with the new windows and door which are modern, practical and in keeping with the historic building."

Sarah Weir
Whitchurch Town Council

Hambledon House, Surrey"The new steel windows and doors are a major feature of this stunning property; in line with the rest of the building they are of a very high standard. Clement have stuck to the various time scales and have helped us with any issues that have arisen after. We have worked together on a few projects now and have been pleased with their service."

Jon James
Contracts Manager at Vale Southern

Stapehill Abbey"The homes at Stapehill Abbey have a mixture of slate and tile roofs, we chose Clement Conservation Rooflights as we needed a product that would look perfect in both. We are really delighted with end result and hope to use Clement rooflights again in the future."

Garry Hunter
Ankers and Rawlings

"Clement Windows were selected following a lot of research, and ultimately because they were able to offer the slimmest profile metal sections. The appearance of the glazing is critical to the whole building design so we worked closely with Clement to achieve the desired appearance, with great success."

Ben Stagg
Stagg Architects

Drax Group"We are delighted with the service and quality of windows supplied and fitted by Clement. The new steel windows fitted in the refurbished building look stunning and exceeded our expectations."

Anne Kerr
Drax Group

"After a lot of research, we chose Clement windows to manufacture our new steel framed leaded French doors and windows to complement our house. The team finely tuned our drawings and took time to make all the elements work with pleasing proportions. The manufacturing lead time was exact and installation was carried out carefully. We had the chance to choose a colour for the powder coating and for our house it gives the frame a softer look than black. The windows look great and have a beautifully slim profile."

Nicola Killeen

"Clement Windows were helpful throughout the planning and responded quickly to our enquiries, and were courteous and not pushy. The steel replacement windows were a perfect match for our old ones, which were not all replaced. The fitters did a fine job and were very good and conscientious workmen."

Alan Fersht

Bert & May"We have worked with Clement a number of times, we love their products and always find them professional. They helped us get the product installed on time at my project so that we could meet our tight deadlines and finish the job. The addition of the Clement steel doors certainly helped us to transform what was an exceedingly average home into the beautiful space it is now. We are really pleased with the final look."

Lee Thornley
Founder and Creative Director at Bert & May

"The team at Clement provided a great service in supplying new windows as part of the Town Hall refurbishment. Very specific aesthetic and energy performance criteria needed to be met when it came to the window replacement. The W20 windows supplied by Clement were able to meet all of these requirements. 

Despite the project being on site at the height of the pandemic, the windows were delivered to programme which enabled seamless installation. Now the building has been brought back into use really positive feedback has been received from both staff and visitors."

John Cattermole
Senior Project Manager at Waltham Forest Town Hall

"We are absolutely delighted with our new steel windows from Clement. They changed old diamond paned windows for a much lighter finish and opened up an ugly bay window, still in keeping with our old cottage. The initial contact was straightforward, the manufacture came in on time, despite Covid and Brexit, and the installation went very smoothly indeed. They’ve come out promptly in the month or so since then to ease the bolts slightly and everything is working perfectly. We would definitely recommend Clement."

Neil Woods & Lisa Rickenberg

Self-contained Pool House"The large steel door screen installed by Clement is perfect, as it allows you to see out completely over the entire pool area, from the self-contained pool house. The doors are in a dark bronze so sit harmoniously with the oak façade and bring a modern yet timeless elegance to the building. When choosing that style of window, I wanted something that would sit within the location with ease, not too modern. Steel framed glazing was the perfect fit.

There are double doors, each about a metre in width so that when they are both open you are connected with the pool area. The doors are splashed and splashed with pool water and never stain or mark which is a huge benefit.I would certainly use Clement again, in fact I have a project in London that I am hoping to use them for!"

Lorna Wright
Lorna Wright Design

Kingsmead"We have been so pleased with the design and build quality of the new sitting room windows that we have progressively replaced most of the remaining original leaded light windows with Clement leaded light windows which are visually an exact replacement of the original windows. We should also add that Clement’s Installation Teams were courteous, efficient, highly professional and did a first rate job on each occasion."

Mr Harte

Wood Ridings"Professional and excellent service provided in replacing our windows on our home in Haslemere, Surrey. Clement windows made the whole exercise a pleasure to deal with and were very happy with the whole team at Clement Windows and our lovely new windows."

Mr and Mrs Sutch

Rusham Road"We installed Clement doors for a domestic client in Wandsworth. The clients were delighted with the door and internal screen. I found Clement’s efficient, responsive and enjoyable to work with. We are currently using them again for another client in Battersea and cannot wait for installation next month. Their doors are made and fitted to a high standard."

Lucy Brooke
Smith Brooke Architects

"The whole project was handled very professionally from initial contact and measuring onwards, with courtesy and installation by the due date – in fact a week early in the end. The installers were pleasant, accurate and swift. The final cost represented good value for money too."

Clive Hawkins

The Tracery, Shropshire"We were very pleased with the attention to detail and finish of the steel windows, Clement took ownership of their section of the project and were able to deliver a complex scheme on time and to a very good standard. They remained client focussed throughout and we will happily use their service again."

James Charters
Director of Charters Property

Mellow End"It was a pleasure to deal with the Clement team who were very professional and had a fine eye for detail. The end result is excellent. All of our windows were replaced and we’re delighted with the way that they have enhanced the look of our house."

Mark Cellier

"Despite the pandemic and the resulting delays in installation they have stayed in contact with us and the end result is stunning. The steel framed windows and doors are well manufactured, carefully installed and look fantastic. We are delighted."

Claire Rimmer

Espirito Santo Architects

"When choosing the right windows for this beautiful house it was important that they would both be in keeping with the character of the building and provide better thermal qualities. We think the new Clement steel windows have done exactly that. They finish off the project perfectly. Our clients are absolutely delighted with the new steel windows and we felt they offered us excellent value for money."

Paulo Espírito Santo
Espirito Santo Architects

Victorian Cottage"Clement Windows replaced all the old metal windows in our Victorian Cottage. We could not be happier with the windows which are exactly what we wanted. The windows are excellent quality and to my relief look very traditional and in keeping with the period style of the property. I love the choices we made with colour and handles and Clement windows were so helpful in guiding us through the decision making process. All the way along they have been so helpful and communicative. The windows arrived sooner than expected and the team who came to fit them could not have been more professional, friendly, tidy, thoughtful and efficient. I am absolutely thrilled that Clement windows exceeded expectations! Thoroughly recommend!!"

Sophie Bateman
West Sussex

"We are thrilled with the doors. Also, I just wanted to let you know that I have never experienced a more professional, efficient and impeccably well-organised service. The process was clearly set out and communicated to me from start to finish. Even your employees let me know exactly when I should expect them. I have dealt with so many tradesmen over the years and none of them have compared. Clement has really been the gold standard and I am so pleased that we went with you. We have one more sliding door that we hope to install in the future and will definitely come back to you for this."

Sophie Beer

"Regardless of historical protection I wouldn't have chosen any other product for my windows and doors. I wanted to embrace the property’s original features and the windows offered by Clement were the only option in my eyes both for style and feel."

Isobel James

Streathbourne Road"The aim was to design a rear extension that allowed my client’s love of her garden to be fully appreciated from both inside and outside the property. The space also had to reflect her passion for all things industrial and Clement metal framed windows were the ideal product to achieve this look, resulting in what I feel is both a sympathetic and special addition to the existing house."

Richard Dewhurst
Interior Architect

"This new build project was a reinterpretation of a Somerset long house and the aim was to strike a careful balance overall between traditional, local and contemporary materials. The black steel windows and doors by Clement lend themselves perfectly to the look which is at once modern and classic. The Clement team worked closely with us throughout the project to ensure our original brief was met, we are really pleased with the end result."

Neil Choudhury
Neil Choudhury Architects

"The service from top to bottom has been faultless. These windows are a bespoke product and it shows! I looked at a number of options for our windows and can say that having now had them installed it was definitely the right decision by far to go with Clement. Clement were not the cheapest quote we got but we decided to spend that bit extra on the windows and it has paid huge dividends in the look, practicality, design and installation service. The after sales service has also been excellent...What more could you ask for!"

Ed Burrows

Melia Hotel, London"Clement Windows were the window replacement contractor to the Melia Hotel (phase 1&2) in London, a Grade 2 Listed Building. I was the Project Manager for all works involved. Clement’s slick manufacturing process and the skill set of the installers ensured the contract was completed ahead of schedule and to a very high standard of finishing, resulting in an almost snag free hand over to a very happy client. Due to the success of phases 1&2 we are in the process of negotiating phase 3 works. Clement Windows will be working with us once again."

Kevin McEnteggart
Corley & Woolley Ltd

"Clement Windows were very helpful – their price was competitive and they efficiently drew the windows and delivered them. I am very pleased with the look of the result, including the curved corner window, which we had been warned was more at risk of minor imperfections than the remainder, but had none that I noticed."

James Dunnett

Twickenham Film Studios

"Since The Lounge opened its doors, it has provided a ‘wow’ factor for staff, tenants and production crews alike. It is also highly sought after as a private hire venue for wrap parties, industry functions and birthdays and with the doors open on to the terrace of a summer’s evening, there is no better place to be in this part of London."

Andrew Boswell
Commercial Director at Twickenham Film Studios

Gillian Abraham"The rooflights look great – both from the outside and inside. They add so much light to the space and make the study area look fabulous. It was a tight schedule getting ready for the TV crew to film the house and the team at Clement were really helpful."

Gillian Abraham

"Excellent service, high quality windows – very pleased and would highly recommend. We had old metal windows replaced and most visitors do not notice the difference in appearance – but we notice the improved insulation with the thin double-glazed units."

Ms Green

"I just wanted to let you know that we are really happy with the windows and door you supplied. They look absolutely fantastic. The fitters were great and they had really cold horrible weather to work in."

Nicola Roberts
ACAD Mapping, East Sussex

"Suffice to say we are VERY pleased with our bespoke new roof window – the quality and finish are excellent, and I’m so pleased that I specified a white internal finish as it looks like a wooden window at first glance – which is what I was hoping for, and the white really brings light in. It floods the hallway with light and totally transforms the space – just magic!"

Kathryn Hall

"We are really pleased with our decision to select Clement to provide new steel windows for this iconic power station development. The service provided by Clement has been brilliant from beginning to end – from the initial quote and drawing stages through to delivery and installation, everything was provided on time and to the high standard we required. We selected EB24 steel screens from Clement because their industrial Art Deco looks are in keeping with those of the original Power Station. However being 21st century double glazed steel screens, they provide outstanding thermal and acoustic performance as well. The outcome is windows that are sympathetic to the original development but also meet the high technical specifications of the project."

Colin Pye
Corporate Accounts Director at AreaSq


"The client approached QKS to carry out a garden room/kitchen extension with the emphasis being on natural light. The old kitchen had been starved of light and the client wanted a social living/eating space that connected to the garden. The Listed Building set in the Northamptonshire village of Kings Cliffe had a lot of challenges regarding the shape and position. The Clement rooflights used were a perfect solution to obtain the light and also work in harmony with the unusual roof design. The client is thrilled with the finished product."

Nick Clipston
Managing Director at QKS Ltd


"The YMCA required a commercially viable 99-bed hostel where 10% of the available beds could be given up to vulnerable young homeless people. The strong relationships built early on in the process with Clement Windows resulted in a conversion that embraced the history and heritage of the old building and blended new materials with old to create a stunning finished project."

Rob Yeandle
John Perkins Construction

The Old Court House

"This Grade II Listed Building was in a dilapidated state and required meticulous and painstaking reconstruction. The inclusion of Clement’s Conservation Rooflights helped us to stay true to the original character of the property whilst also meeting the demands of Building Regulations."

Rhys Brookes
Harrison Brookes Architects

The Pithay

"Constructed in the 1960s and one of Bristol’s landmark buildings The Pithay had become tired, dated and lacked purpose. A plan was developed to revitalise and regenerate the building, transforming it into a commercial hub. The refurbishment of the façade required great sensitivity given the surrounding Conservation Area and Listed Buildings. The steel windows from Clement provide the perfect solution – modern double glazed, thermally efficient versions of the single glazed originals which incidentally they supplied when it was first built!"

Liz Barnard

"Absolutely thrilled with our patio doors and conservation skylight windows from Clement. Service was excellent throughout and minor issues were sorted quickly."

Mel Leslie

"Clement Windows have been extremely professional, entirely reliable and very friendly. They are not the cheapest window suppliers but the quality of their products and services is great."

S Da Soller

"The window installers have finished the work and we are delighted with the outcome. The replacement windows exactly match the originals, except, of course they are double glazed, which is what we wanted to achieve. We are now the second house in the road with Clement windows! [The team] were highly professional and left everything clean and tidy. It was a pleasure to have them in them here and we would unhesitatingly recommend them."

M Sanders
W Sussex

Old Marylebone Town Hall

"With Old Marylebone Town Hall one of the challenges we faced was the introduction of a contemporary glazed link between the Council House and the Annex building while conserving the period features of such an iconic landmark. Clement’s windows provided the 1920s appearance, while bringing all the benefits of a modern window, a look which perfectly matches these historic premises. The Clement team were great to work with and any issues were resolved promptly and of course the windows look fantastic!"

Dave Nott
Project Director at Wates Construction London

"I have used Clement Windows on three occasions. The first was to replace patio doors to a bespoke design, the second and third occasions were to replace all of the windows in my house which were undertaken at my request as two separate jobs to reduce disturbance. I specifically wanted steel windows to replace the 1930's original metal windows installed when the house was built. I thoroughly reviewed the market and was satisfied that Clements were by far the best quality. Two of the jobs had problems. One of them was concerned with poor window installation whilst in the other case I rejected the design and finish of the bespoke patio doors.

I've been in business for many years and understand that things sometimes go wrong. The important thing is how problems are dealt with. In this respect Clements response was exemplary. They timely remanufactured the patio doors and carried out remedial work to the window installation. I'm very happy with everything Clements have supplied and installed. Moreover, they're decent people to deal with."

Mr Richard Kendle

"Efficient and professional approach with great quality results. Even the Hampstead garden Suburb trust could find no fault in our new windows."

Professor Bogdanor
Hampstead Garden Suburb

Clement Windows

"The client wanted to make sure that the building could still be ‘read’ as it was in Conan Doyle’s day and to be as true to the original as possible. The windows by Clement faithfully replicate the originals, letting in as much natural daylight as possible, providing a spacious, bright and positive environment for the students."

Michael O’Brien
Director O&D Construction

Clement steel screens and doors

"I am delighted with my stylish Clement steel screens and doors. The pool is used for private swimming lessons and the glazed screens make it a wonderful light and airy space whilst also creating a warm and safe environment for the parent and baby classes."

Residential Client

Clement Windows

"As an Architect working on private houses, I have used Clement Windows on a few projects now and have found them to be responsive with their pricing / detailed design / production information and helpful / neat on site. Any minor problems have been put right immediately and my clients have been more than happy with the outcome. Their steel windows are of good quality and have looked great in both heritage settings and modern interiors."

Emma Adams
Emma Adams Architect Ltd

Fleet Street

"The lighting scheme was an important feature of this office refurbishment which incorporates a dynamic daylighting system to control the light intensity of the space, which in turn helps to maintain staff’s natural body clocks. Clement’s internal steel-framed windows maximise the amount of light in the office, thus contributing to the overall wellbeing of the office workers. We chose Clement windows due to their external aesthetic aiding the feel that the space was not purely internal."

Martin Helyer
Director at HD Architects

The Maple Building, London

"The Maple Building is our flagship development. It has bags of industrial charm and period character due to its many original features. The steel windows by Clement respect and enhance these while simultaneously complementing the high specification modern interior design of the project."

Gemma Gordon-Duff
Managing Director at Gordon-Duff & Linton

Dimsdale House

"I have had the pleasure of working with Clement Windows as an interior designer. I have found their service excellent from the early design stages right through to installation. They are always willing to discuss technical details and overcome difficulties where required. For example, on one particular project, we had to tailor the screens to meet specific Building Regulations and they were on hand to offer solutions that resulted in approval of the design. The products themselves look fantastic and I would not hesitate to recommend them to clients or use them in the future."

Cherie Lee
Director at Cherie Lee Interiors

"Clement manufactured and installed a kitchen/diner partition consisting of a double steel frame door in our newly built extension. Our experience with Clement in all stages of the project has been very positive and we are extremely happy with the quality of workmanship and the final product. Clement also dealt with a minor post installation issue in a professional and courteous manner. We would have no hesitation in recommending Clement to anyone looking for a highly professional supplier."

Mr Kaljevic

Framlingham College

"As a Grade II Listed Building in the town’s Conservation Area, it is imperative that the replacement windows for the boarding accommodation in the main building at Framlingham College meet planning requirements as well as providing a comfortable and safe environment for the boys. Over several years, Clement Windows have undertaken a replacement programme of the windows throughout the College’s main building and we have been delighted with the planning, design and installation of the windows in many different configurations. We look forward to completing the replacement programme with Clement in the near future."

Andrew Payn
Operations Director at Framlingham College

Bert & May

"We love our Clement screen – it is the perfect frame for the entrance to our workspace and allows us to feel part of the larger warehouse whilst retaining the warmth of our office. The installation was super swift too with minimal disruption to our work. Thank you Clement!"

Harriet Roberts
Founder of Bert & May

"We are delighted with our new EB24 steel windows, which are everything we'd hoped for and which completely preserve the authentic '1937 look' of our house. Clement Windows did everything they said they would to the schedule we'd agreed. We received excellent advice from their surveyor, and cannot sufficiently praise the installation team, who were courteous, efficient and professional throughout. This was a truly glitch-free process from start to finish."

John Guy and Julia Fox
North London

The Sanctuary Battersea London

"We wanted to create something high quality but out of the ordinary and to play on the building’s idiosyncratic features. The windows supplied by Clement are unusual and make a statement whilst simultaneously satisfying the demands of the Conservation Officers. We are delighted with the end result."

Nick Laurence
Co-founder of The James Laurence Group

Harleyford Court

"It was essential that Harleyford Court, which is in a Conservation Area, retained its original 1930s character after the refurbishment. We were very impressed with the close match Clement were able to provide to the historic steel windows and with their ability to provide modern thermal performance. We would recommend this company for similar refurbishment projects."

Doug Black
London Borough of Lambeth’s Conservation and Urban Design department

Architectural Digest

"We proudly represent Clement Windows Ltd here in the United States of America. It’s always a pleasure to work with Clement Windows.

We have successfully completed many projects throughout Manhattan together. They delivered each project quickly and on time. One project in particular was published and featured on the cover of the April 2012 Architectural Digest Magazine.

They have a strong commitment to client satisfaction and attention to detail. Our clients have commented that Clement's product quality is exceptional and their finishes are beautiful."

Peter Warren, Vice President, Skyline Windows

de Gournay's stand at the Decorex fair

"Clement Windows were commissioned to craft a beautiful installation of steel windows and doors at de Gournay's stand at the Decorex fair. From start to finish the project was handled very professionally and Clement Windows interpreted and executed the brief perfectly and on time. They were an absolute delight to work with and I would have no hesitation in recommending them to any of our clients in the future. "

Hannah Cecil Gurney – de Gournay

Granit Chartered Architects

"Clement’s steel window is a fantastic looking, high quality product that added the contemporary industrial aesthetic that our client was looking for. With their assistance we were able to create a double height glazed wall that flooded the library and basement with natural daylight.

We would highly recommend specifying their product in future projects."

James Munro, Director – Granit Chartered Architects

"Clement built over 30 bespoke windows for our mock-Gothic 1850s tower, some arched, some rectangular, each individually sized, in both fixed and opening format. From measurements to fitment (which occurred on time and according to plan), all company employees were courteous, polite, helpful and informative.

The windows themselves are fantastic, dramatically reducing our heat loss and energy bills during the winter, and the darkened internal frame means that despite the bespoke 12mm air gap, the windows do not look double glazed on first inspection (so the Listed Buildings Officer was very happy). From the outside, the powder coating and leading are flawless, complementing the character of the building perfectly.

All in all, working with Clement was a fantastic experience and I'd recommend them to anyone with a listed property."

Mr M Peck, Northamptonshire

"The work Clement Windows completed on our house really has made the most difference in improving the aesthetics and functionality. The whole Clement team have been wonderful to work with. Nothing has been too much trouble. You have a real focus on client care and attention to detail."

Mrs J Griffiths, Guildford

EB24 steel windows, Surrey

"A lot of careful consideration went into choosing the right windows and doors for our new build project. After seeing the elegant frames of steel windows we knew they were the right choice but we had to ensure the product we chose met the required criteria for Building Regulations. Our builder Jim Brooks recommended EB24 steel windows by Clement as he had experience of both the product and company. EB24 not only met the required energy ratings for planning but it also offered the exact look we wanted to achieve. We are delighted with the windows and doors by Clement and the procurement process was absolutely great."

Mr Casserly,

Henley College

"Clement Windows were selected to replace the windows in the old manor house on our Rotherfield site last year. We were very pleased both with the quality of the finished product and the installation which was carried out carefully and efficiently by their installation team under the supervision of an excellent site foreman. We would be pleased to recommend both the product and Clement Windows in future."

Nikki Hounsell,
Property and Estates Manager at Henley College


"We are very pleased with our new windows. They look good and most of the drafts and noise we suffered from previously has been eliminated. Clement's installers were outstanding as well, working through two of the coldest days of the winter to get the job done to our satisfaction and on time."

Mr P Latham,

uarmby Construction

"The design objectives were to replicate the original windows. This was achieved to the satisfaction of the client, the architect and the planners. Clement succeeded in quality and programme. We have learnt that some companies can achieve what they promise!"

Peter Martin,
Site Manager, Quarmby Construction

Mr Hughes

"Our whole house, including its three extensions, now has windows supplied and fitted by Clement Windows. Not only are the new windows extremely well made and fitted, they preserve the character of the house which used to have leaded lights which were fitted into the brickwork without a wooden frame. The unusual but very attractive effect which this had has been preserved with the added benefits of properly insulated windows constructed to a very high standard. We are extremely pleased with the result."

Mr Hughes,

Mrs Turner

"I would just like to say how pleased we are with our windows, they have improved the appearance of the whole house and look fantastic. I would also like to thank the installation team who were friendly and efficient, completing the job ahead of schedule."

Mrs Turner,

"I need to write to express my thanks for a magnificent job well done. The new windows are beautiful and were installed so carefully and efficiently, a testament to the skill and friendliness of your staff. I must mention your two Senior Operatives who were fantastic, skilful yet careful and always tidy, making an inherently messy job into one with virtually no impact on the operation of the household. Both my wife and I are very grateful and shall recommend Clement Windows Ltd."

Mr Watt,

Mr Ken Wild

"Right from the time of the first visit by a Clement Windows’ representative (Peter Clement himself) we were impressed. The service was really excellent. The final product itself fully lives up to Peter’s claims. It is a very high quality product and we feel our home has been significantly enhanced.

The windows look just as good as the originals, and have much better locking arrangements. A very good product, fitted with excellent service.

We’ve already recommended the company to a number of our friends. Thank you."

Mr Ken Wild,

Caren Buchanan

"The whole project exceeded our expectations - we were seriously impressed by the installation team, who not only did an excellent professional job, but were unfailingly pleasant, hardworking and efficient which made the whole process unbelievably easy for us. Our thanks to them - we speak from experience having had of a lot of building work done!"

Caren Buchanan,

Eric Anderson

"Dealing with Clement Windows Projects was refreshingly different. Their approach was total commitment to achieving promises and targets made throughout the project ensuring that business relationships were pleasant, rewarding and successful for all concerned."

Eric Anderson,
Building Surveyor, Synergy Construction & Property Consultants LLP

"Clement supply a quality product with much care given to installation and the convenience of the client. We are very pleased with our new Clement windows and doors, they complement the character of our house and we consider them to be a worthwhile investment."

Tim Lansley,

"This is the second time I have ordered windows from Clement. As before, they arrived and were fitted before the date I was promised. The fitters were very efficient, completing all the work in one day. And the quality is outstanding. My first Clement windows have been in situ for over 10 years now and they have never given me any problems."

Andrew Nelson
Winchester, Hampshire

Ziomek Wiertelak

"This was a project with a high degree of difficulty in an important Conservation Area. I have not used steel windows before but if I require them in the future I would happily go back to Clement Windows. Their quality of both product and fitting service was high and they delivered on time. A job well done and our client is very pleased."

Mr Gardner

"Clement Windows have been a pleasure to work with from first enquiry through to installation and subsequent follow up. Their product is very high quality, and their installation team did an immaculate job, the internal decorations being virtually undamaged. The style of window is a good match to the original of our 1929 house."

Mr Gardner,

"It is difficult to get it right when choosing a window for a new build. Clement were very helpful in offering me samples and advice at the design stage. They followed the process through to supply with good support. The slim elegant look of the windows wins over aluminium (in particular when the window area is small). I would definitely recommend Clement’s product to successfully deliver a contemporary look."

Peter Clayton

"I searched for a long time to find a manufacturer who could replace my existing single glazed windows and doors with an exact steel, double glazed equivalent which would preserve the attractive Georgian appearance and also would be white on the inside and black outside. Clement Windows have done precisely this. The appearance inside and out is exactly as before. I am delighted with the result and happy to commend Clement for their efficiency and service."

"An important measure of the quality of a supplier is whether a client would recommend that supplier to somebody else. I would have no hesitation in doing so. Clement Windows have a first class product. By "product" I don't just mean the quality of the windows but the total package from the pre-sales consulation with the client (do not underestimate this!) to the post-sales follow up. What you are buying is something that is distinctive in both design and quality terms."

"A fantastic installation. The conduct of Clement’s operatives and the quality of their workmanship was second to none and the speed of the installation whilst maintaining the high standards which were set is testament to the operatives working for the company. Everything seemed to be carried out in such a trouble free manner, from getting the specification correct to the installation being completed. We hope to be working alongside Clement Windows again in the near future."

"The windows are first class and well worth the investment made.They are not only stylish and incredibly secure, but also provide superb insulation quality, keeping rooms cool in the summer, but also warm and snug during those long winter months to come. They have made an enormous difference to us already and we would not hesitate in recommending them."

Mr & Mrs Booth

"The entire Clement team is most impressive, both on site and at Haslemere. There is always someone to deal with phone calls in the office – a very attentive and helpful group of people. The window fitting teams have been exemplary – very polite, no shouting, no radios blaring and very impressive workers, highly experienced and always leaving everything clean and tidy behind them. In our opinion the end product is so visually stunning that it is well worth the cost and the wait. What also has to be taken into account is the value that is added to the property and that these windows are maintenance free, therefore saving many thousands of pounds in builder/painter/decorator’s fees in the future."

"I am pleased to say that many friends and colleagues have regularly spoken highly of this well known Haslemere company. Recently in my capacity as Chairman of Haslemere Museum in Surrey we placed an order for a replica pair of steel doors with sidelights to match the originals for this important Grade II listed building and these have now been installed. The job was extremely well done."

"In my experience with Clement Windows, I found their product to be exceptional. The quality is excellent, and their finishes are beautiful. They have great functionality and they were delivered quickly and on time."
