Highly recommend Derwent windows and doors , they are a fantastic company to deal with. We are very pleased with our new front door. Thank you x Service: General door installation

Sash window replacement. Work carried out without a hitch. Always polite and cleared up afterwards. Arrived on time. Would recommend.

Needed some advice about windows fitted by Derwent. No problems. Polite and courteous as always. Thanks.

Really poor customer service. 6 months of planing an then told they can't install. Please do not give this company your order.

We first used Derwent nearly 3 years ago to replace the door and windows at the front and then just recently to replace the rear windows. Both times they have been spot on and I would definitely recommend them without hesitation. As others have said, they came in slightly more expensive than other firms but their attention to detail on the fitting and finishing touches is outstanding. The first time, we had two windows knocked into one and they plastered, trimmed stonework etc and now you wouldn't know there was once two windows there. Second time they had a high window to replace on a stairwell but handled the challenge with ease. They are very friendly and super tidy, minimal touching up of paintwork needed. Thank you.

Had our French doors fitted the workmanship was second too none well done and thanks Andy for a sterling job.... Would have no qualms in recommending this company and will defo use again .

Fantastic service from start to finish. Large project of over 40 windows/doors/bifold etc with differing styles from traditional sash at the front of the house to a more contemporary design to the rear undertaken through 4 phases of work over a three years time period and the customer service levels, professionalism and quality remained at a high level throughout this period. A lot of support around getting the correct specification from numerous meetings, use of the showroom and the prompt return of calls/enquires to clarify the smallest detail and the level of patience/support during the various project time periods was key. As the project was conducted over 3 years and four phases we had a wide selection of team members as well as some familiar faces working at our property but all set very high standards in terms of professionalism, cleanliness and quality of work. Snagging was a breeze as the team had already completed their own snagging list and kept us fully informed throughout the phase of each project. Just remains to say thanks and would highly recommend.

Excellent showroom with a large range of quality products. Helpful staff and after sales care.

We had all the windows in our house changed from their original wood to evolution flush and have to say they look fantastic. We were really worried about going to pvc but they look every bit as good as wood. The company itself is the definition of professional. I can't praise the fitters enough for their attention to detail. They made virtually no mess and I expected extensive repainting after but actually only had to touch up one or two windows. Absolutely amazing to watch them work. Don't hesitate to go with this firm. Im sure they will be around for years if any problems should arise. 5 stars all the way.

Really beautiful door fitted by the nicest guy. Quick job. Clean and tidy. Will be back for the windows!
