See what our clients have to say about us.
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
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 Design
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.
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
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.
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.
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.
Director of Charters Property
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.
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.
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.

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!!
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.
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.
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.
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 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!
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.
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 Architects
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.
Commercial Director at Twickenham Film Studios
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.
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.
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.
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!
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.
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.
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.
John Perkins Construction
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.
Harrison Brookes Architects
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!
Absolutely thrilled with our patio doors and conservation skylight windows from Clement. Service was excellent throughout and minor issues were sorted quickly.
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.
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!
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.
Hampstead Garden Suburb
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.
Director O&D Construction
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.
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 Architect Ltd
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.
Director at HD Architects
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.
Managing Director at Gordon-Duff & Linton
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.
Director at Cherie Lee Interiors
Clement manufactured and installed a kitchen/diner partition consisting of a double crittal style 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.
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.
Operations Director at Framlingham College
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!
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
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.
Co-founder of The James Laurence Group
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.
London Borough of Lambeth’s Conservation and Urban Design department
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
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
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
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.
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.
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,
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!
Site Manager, Quarmby Construction
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.
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.
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.
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,
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!
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.
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.
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.
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.
New Wave Builders Ltd, Hampstead Garden Suburb London
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.
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.
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.
Horsham, West Sussex
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.
SEDAC Limited, Crowborough, East Sussex
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.
Hampstead Garden Suburb
Clement did what they said they would do on the Market Hostel project – they were on time and delivered a first class product and service.
John Cole Bland,
Brown and Cole Architects, Cambridge
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.
Mr & Mrs Booth
Heyshott, West Sussex
What impressed me more than anything else was the friendliness of the Clement fitting team, they couldn’t do enough for you.
My experience of Clement goes back many years and in that time I have found them to be a fine company to deal with, thoroughly professional from top to bottom… their work has always been of a high quality.
SCW Massingale FRICS Massingale and Co Chartered Surveyors
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.
Chairman of Haslemere Museum, Haslemere, Surrey
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.
Interior Management Inc, New York
The steel windows and doors supplied by Clement when we opened 22 years ago have proved to be robust, and we have been very pleased with them both aesthetically and functionally.
