Internal Blinds

Windows with built-in blinds are the perfect solution for many commercial buildings such as offices, hospitals, schools, universities, hotels, leisure centres, retail and public sector buildings.

Many businesses choose commercial window blinds for their external windows and glass partition walls and doors to create a contemporary appearance, flexible spaces with greater privacy and clean sight lines.

For the public sector, including council premises, hospitals, universities and schools, integral blinds offer the added benefit of being hygienically fitted between the panes of glass, keeping them away from damage, dirt and dust – making them easy to clean and maintain in the long term.

Integral blinds for commercial and public buildings are practical and stylish and are available in a wide range of colours.

Customer Testimonials

Julie and I are very happy with our new doors. The profile gives a lovely sleek finish which we are both very happy with. Can you pass on our big thanks to the fitters, the installation was amazing. The finish is flawless. Apart from the doors being brand new you can hardly tell the difference. The site was left spotless as well.

Julie & Hunter - Epsom

I just wanted to let you know how delighted we are with the new windows and patio doors. Your guys were so brilliant and absolutely professional so please pass on our thanks to them too.

Many thanks to db Designs for fitting our bifold last month. I am extremely pleased with the professional service from the quote to the fitting. Brilliant finish and great value, cheers.

Sarah Young

We have just had an excellent installation from Db Designs. Very helpful, respectful of Covid and just pleasant staff all round. Have recommended them to a friend already.

Keith Margetts

Very pleased with my new windows and patio doors. Very polite and experienced men who fitted them leaving no mess either day! Efficient service, excellent value and good to support a well established family firm. Would thoroughly recommend.

Sally

Many thanks for the installation on Thursday 8th June. It was very smooth. The guys were efficient, tidy and polite and have done a good job. We’re happy with the new doors. Thank you

Emma Salaman

I wanted to tell you how pleased we are with the windows and the whole job fitted by John and Shaun. They are excellent workers and we recommend your firm and installers to all who are keen to find out who did the work. They were considerate, very clean, tidied up after work every day (weather was awful) and worked very hard.

Kathy & Eddie - Ashtead

We are delighted with our new windows and doors. Your fitters were wonderful. Very polite and tidy. There is hardly any making good to be done on the inside around the window boards – we expected to have to repaper, but there is no need.

L. Collumbell - Ashtead

DB Designs have provided me with many windows and patio doors and they have always given great service. The latest work they did for me was to replace the bi-fold doors across the back of the house (originally also supplied by them, with never any problems). They arrived promptly at the appointed time, worked quickly and tidily, and cleared up immaculately when they had finished. I’m delighted with the result. Wouldn’t hesitate to recommend.

Lesley Miles
From start to finish the whole process of replacing our windows has been flawless Dom and Sally answered all our questions and explained everything in detail of how the process was to work with changing the windows. It really has made a HUGE difference to our flat. Our windows were over 25 years old and seeing the view from our windows with the new windows was amazing. In fact I spent the first night admiring

We wanted to use a local company and DB Design were brilliant. Dominic was efficient and always very helpful and patient especially when we were choosing our front door!

A long than anticipated wait for installation of double glazing but every other aspect was top notch. Updated helpful , and very good installation itself. Also after sales excellent and quick to rectify a very minor issue, I can highly recommend this company.

Dave Morrell

This week DB Designs fitted our new windows and front door and we are SO pleased with them. Right from the beginning, the advice we had was brilliant, a very reasonable price and then the fitting was seamless (lovely guys who worked so hard and left the house immaculate afterwards). Thanks so much, we’ll be recommending them to everyone!

Kelly Matcham

We are both pleased with the service provided and also the quality of the fitted units. ln particular, your team has a good eye for attention to detail and also did an excellent job in clearing up afterwards.

Peter Wilson
Db designs fitted my final third stage Windows this year, 2021, spaced over a few years as I could afford. They are all lovely and the measuring, advice, fitting and final touches all perfect. I’m delighted with the quality and the price but most of all Dom’s advice. One my first set of windows was to the rear, he advised a small change to ensure the new windows matched seamlessly with one existing, and when

Just a quick note to say Thank You so much – your guys yesterday did a very very good job, they were a credit to you and you should be very proud of them. To say we are delighted with the Bi-fold doors and the way they were installed would be an understatement 🙂

Phil B.
DB Designs replaced all our old aluminium-framed windows and patio doors with UPVC, new window boards throughout and replaced a warped wooden front door with a composite one. Dom is knowledgeable and his advice and guidance turned out to be spot on, from the type of pattern to obscure the toilet and bathroom panes, to the thickness and style of the front door. When we wanted bi-fold doors into the garden, Dom explained why this

I now have a very nice front porch door and a much better back garage door thanks to you and your very skilled Installation team. Thank you again for a really good job well done.

Renate Beard

Fitted windows, French doors and exterior doors on our property (March 2021). Great customer service from Dominic, who gave a lot of useful advice. No pushy double glazing hard sell and no high balling the quote, which was refreshing. Installers were efficient and very tidy. I would definitely recommend them.

Trevor Ryan

We had the quarterly church hall committee meeting this week and everyone was hugely impressed with the work you’ve done.

Thank you so very much. We were lucky to find you. You were recommended

Odette & Nick Pineger
We first used DB Designs several years ago when we had a new roof installed over our conservatory. Since then we have had all the house windows and doors replaced on two properties. Each time DB Designs did an excellent job and we have enjoyed quieter, warmer and more secure homes to live in. In particular I liked the fact that when Dominic came to measure up for the quotes he explained that the price

Thank you for supplying and fitting a double glazed sealed unit in our patio door. Both the Lees were very helpful and professional in their approach and we are very pleased with the end result. Would recommend.

B G

Just wanted to say a huge thanks to you & your colleagues for the new doors & window unit. They look great! And we also really appreciate how patient the guys were with our noisy puppy, Luca, and what a meticulous job they did tidying up once they’d finished. Many thanks again Helen & Peter

Helen & Peter

Great service and friendly advice from Dom and a highly professional installation by his Team. Highly recommended.

Hanna

Pleased to say the house is noticeably warmer since the new windows were installed so I think we can say we have done our bit for climate change! More importantly, I hope the gas bills will go down a bit.

Headley

We are getting great pleasure from the conservatory and with the exception of the very hottest days in the summer I can confirm that you were correct that the roof deflected a lot of the heat and sitting in was no problem. Well done and thank you.

Philip and Sandra
We called DB designs following recommendations from a decorator who was doing work in our house, and we have been delighted with all the work the team have done. Quick to come over and give advice and quote, and the team who actually do the job are very professional and good at what they do. DB designs have done 3 separate jobs in our house- including replacement of a window, installation of a composite door

Sandra Lambert

Just wanted to say we absolutely love the door, it’s beautiful! We’re so pleased. The gents that came to fit were so efficient and left it so nice and tidy. Thank you.

I have just had a new front door and some replacement windows fitted. I am delighted with the end result. Everything was done to a very high standard indeed and the team were knowledgeable, careful and competent. Excellent!

Angela Basaclk

Firstly many thanks to Dominic for his infinite patience and willingness to help and advise over the protracted period between his initial visit and the commencement of the installation. The team of 4 fitters were polite, hardworking and effectively led by Lee. All the work was completed to a high standard and has significantly enhanced the appearance of our house. We recommend DB Designs to anybody planning to upgrade their double glazing.

Margaret

Excellent service from start to finish. From the appointment times arriving when said to insulating the windows. The guys were efficient and very clean working. Great company would definitely recommend.

Jenny Munslow

Excellent installation, again. 3rd time we’ve used them. Their installers are really good.

Bookham Bowling Club – replacement of windows and doors into our 90 year old Pavilion which is now a storage shed. UPVC equipment used throughout the 2 day install by their fitter. Cracking job done.

We are delighted with our windows installed earlier this month by DB designs. Both of our children’s bedrooms feel warmer and cosier and look infinitely smarter as a result. Communication was good with Dominic and the installation team were friendly, professional, quick and very tidy. I would highly recommend DB designs to anyone else.
