An extremely professional and helpful company with every member of the team from the start to the end of the process fantastic. They listened to my requests and have changed two french doors with side half windows into to two french doors with full length side panels which has totally transformed our view of the garden. High recommend using oak, as even though it was far more expensive the gain really comes out in the finish of the wood. Will definitely only use this company for windows in the future.

We are very pleased with our new windows and doors. Derwent Windows have been extremely helpful and professional throughout the entire process. We will be engaging them again next year to have our extension windows and doors installed. We would happily recommend Derwent Windows to anyone, and would be only too pleased to provide a reference if it is required.

We recently had new wooden doors and windows fitted. Due to the fact that they were bespoke, we had to wait 12 weeks for them , but they were well worth the wait. Derwent Sash Windows Ltd did a beautiful job: neat, fast and professional. I was particularly impressed with the care taken to protect my furniture and belongings during the work, and they did a great job of tidying up afterwards. Communication was prompt, professional and warm, and they even took the trouble to returning a beloved keyring I had inadvertently left in my old door.

As a self-confessed high maintenance customer, I demanded a lot of time and attention from Derwent Sash Windows Ltd, and they more than met my high expectations throughout the buying, installation and aftercare service. I visited the beautiful showroom a fair few times while choosing the products, and was always met with patience, courtesy and expertise. The installation went like clock work. Many thanks to Mark for his exceptional skill installing my product from Timber Windows & Doors.

New Front Door

New Front Door Just had a new front door and surrounding windows in our porch from Derwent. We wanted 1930's style to be in keeping with our house built in 1929. All the Derwent staff were very helpful and provided excellent service and advice from start to finish. We wanted a stained glass design to match our original bay windows and Derwent put us in touch with their specialist glass supplier who made the windows to our design which look great! During installation, both fitters were really skilled and ensured a good job was done, including joinery and some plastering. Once again - thank you Derwent !

We have used Derwent windows over the past 5+ years to supply and fit several large sash windows in our property, including a bay window. They have always been professional in their dealings. When it comes to installation the fitters make sure that there is no mess and that the fitting inconveniences you as little as possible. I would highly recommend Derwent Sash Windows and will continue to use them for the rest of the house's windows.

From my initial contact with Derwent Windows right through to the finished installation they have been totally professional, knowledgeable, courteous, and efficient. I had many discussions with Derwent about how best to achieve my desired result, and nothing in the whole process was too much trouble for them. They always answered my many queries, discussed all my options, and tailored a package to suit my specific needs. Once the window specifications were agreed they were manufactured and delivered on time, and fitted to an exceptionally high standard. The professional fitters dust-sheeted everywhere, and on completion cleaned up leaving no trace of ever being there. The windows are of the highest quality and beautifully installed. Everyone with whom I dealt at Derwent Windows has been brilliant. They made the whole process stress free, and I would absolutely recommend them to anyone looking for truly excellent customer service, highly trained professional staff, and a superb end result. Thank you Derwent Windows!

Quality door in traditional style

I chose Derwent Windows because they have a reputation for quality. I liked the fact that I could look around the showroom before I ordered. I wanted a traditional wooden stable door for the back of my old cottage to replace a hideous upvc door fitted by a previous owner. I also wanted modern locking and security. I also wanted a big window in the top half so I can see my garden. The door is completely bespoke, basically I could have what I wanted. It's made of engineered hardwood, has an impressive 30 year guarantee against rot and will outlast me I'm sure. The surveyor came out to measure up and advise me on a few things I hadn't thought about. The door was fitted on schedule and without fuss in quite a tricky, wonky space. It looks great and has put all the character back into my cottage. Definitely recommend DSW.

This is the second time we've used Derwent Windows. Last year bedroom windows were replaced and we really noticed the difference over the cold winter. Now we've had landing, bathroom and kitchen. The windows look really smart both inside and out. The quality is superb. They're not cheap but you get what you pay. Every one at Derwent Windows are great. Particularly the two fitters Ian and Mark. Andy is also very helpful and will follow up any queries. I would strongly recommend them.
