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.

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.

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 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.

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.

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.

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.

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.

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.

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

Latham

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,
Surrey

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,
Surrey

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,
Surrey

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,
Hampshire

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,
Middlesex

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!

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.

Mr Sutch

We are absolutely delighted with the steel windows from Clement. Aesthetically they are very sympathetic to the original style of the house which was our primary concern. The team at Clement made every effort to recreate the original effect, which considering these are modern double glazed windows, was a very accomplished job. Installation was straightforward and very speedy. The installers were very tidy, clean and courteous. I would be very happy indeed to recommend Clement Windows.

Mr Sutch,
Surrey

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,
Bristol

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

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.

New Wave Builders Ltd, Hampstead Garden Suburb London

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,
Surrey

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.

Dominique Webb

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.

Peter Clayton
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.

Federico Rafael
Barnes, London

Graham Towner

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.

Peter Yeates

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.

Peter Yeates,
Hampstead Garden Suburb

John Cole Bland

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.

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.

Mr & Mrs Booth
Heyshott, West Sussex

Mrs Greaves

What impressed me more than anything else was the friendliness of the Clement fitting team, they couldn’t do enough for you.

Mrs Greaves
Bramshott, Hampshire

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.

Alan Perry
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.

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.
