First time we have used Derwent Windows and they were excellent from start to finish. We had two wooden sash windows installed to match the rest of the windows in our house. The fitters were prompt, polite and did a very professional job. They kept us informed throughout the fitting, regularly checking with us to make sure we were happy with progress and at the end made sure that everything was clean and tidy and to our satisfaction. We would definitely use them again and in fact I have just recommended them to a neighbour who saw our new windows and was very impressed

Living in a Conservation Area we thought long and hard about UPVC windows. After much research we came across Derwent in 2018 and they have replaced most of our windows, both casement and sash, in stages over the past six years. We have been extremely happy with the quality of the windows and the workmanship. Any minor snags have quickly been dealt with. The staff are all very pleasant and I would have no hesitation whatsoever in recommending this company.

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.

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.

Had a new front door and 3 windows installed in 2019 which we were really pleased with. Had a new utility door installed this year and again really pleased with the process throughout - everyone was friendly, and professional. Great service and the door is looking great.

I had 5 replacement sash windows and front and back door. I am absolutely delighted with them. They look amazing. I had a few quotes in and Derwent stood out by a mile from the start. Definitely recommend a visit to the showroom. The fitters did an excellent job and clearly take a pride in their work. Would rate 10/10

Decided to replace 2 doors and 2 windows including our front door..Viewed the products at a local showroom and obviously they were of very good quality.The surveyor was very experienced and was able to answer all our enquiries.Long lead time for manufacture but we were very pleased with the quality once fitted.The fitters were excellent working hard throughout the day despite heavy rain even refitting Venetian blinds afterwards which we thought we would have to do. Although they inadvertently cut through a telephone cable which both we and they thought was redundant when it turned out it wasn’t they successfully repaired the severance. Overall very happy with the product and extremely happy with the fitting.

Many thanks, our new sash window with the 120 year old original stained glass encapsulated within it looks great. And much more robust than the original had become!

I have used Derwent Windows in the past and was pleased with the work they did, so when I needed a new door I was happy to go back. As before they were punctual and did a good job. I am happy I went back to them.
