We have recently had a wooden stable door fitted in a stone cottage, by Derwent windows . This is a very good product from timber windows. Dougie the installer arrived promptly as arranged, the installation was first class in very poor conditions. Not the cheapest door available but the total service make this worthwhile. Highly recommend and would use this company again.

We have recently had the windows on the front of our house replaced by Derwent Windows. Callum and Ben were first rate fitters. They worked incredibly hard with attention to detail. They left the site spotless. We have used the company before and will use them in the future. The quality of the Windows is excellent. Thank you Derwent!

Derwent Windows was initially recommended to me by my neighbours who had had all their windows replaced and were very satisfied. From this recommendation I had 2 windows replaced a couple of years ago and was more than happy with them. I have now had a replacement door to the balcony with a top window fitted this week. I'm delighted. There was quite a delay from ordering the door to it being fitted but in this Covid year that is no surprise. The 2 fitters did an excellent job and left the room very clean and tidy. I was shown very carefully how to operate the locks and I was impressed by how careful the fitters were in protecting the stair carpet. The products aren't cheap but the quality is excellent.

We went with Derwent windows because my parents had all their windows and doors fitted by them and was extremely happy and couldn’t speak highly enough of the service from the business owner to the fitters. After my parent's house was finished most of the other houses on the street had doors or windows from the same company just because they saw what a good job they’d done. We only had the front and rear door replaced but from looking around the great showroom they didn’t pressure you and was all very friendly and knowledgable. After we decided what we wanted it was emailed to us how the doors would look and the cost. The fitter was fantastic and a credit to the company, Really friendly, didn’t rush and did the job to the highest standard. Before he left both him and the owner of the business asked if we were happy with the job. Without doubt, if I need anything else or anyone asks who they should use for this sort of work I’d 100% recommend Derwent windows.

We would highly recommend this company, as they work to a very high standard, along with having excellent communication before, during and after the job. We had our upstairs window enlarged to accommodation bi fold doors, which has created a fantastic space, which we are thrilled with. Everyone involved was polite, and respectful, especially so in the the current circumstances relating to the Covid pandemic. We cannot recommend them enough, as we have used to company for many years now, and have always been pleased with the outcome.

Not cheap and pitched as a top of the range product we bought 6 sash windows and an external door for an old stone cottage. Throughout Derwent windows provided a clear, responsive and professional service, they managed our expectations and the team doing the installation were top notch. Time will be the real test of product quality but from the experience to date I have high hopes and no problems commending Derwent Windows for their delivery.

The sash windows of our Edwardian semi needed replacing. Our next-door neighbours had theirs replaced some years ago, by Derwent Windows, and have been very pleased with them. We thought they looked very good quality, as well as visually being almost indistinguishable from our originals. From the first contact with Derwent Windows through measuring, quotation, showroom visit to installation, the whole process has been excellent. All the staff have been friendly, helpful, knowledgeable and skilful. The quality of the windows and workmanship couldn't be bettered. We have already recommended this company to friends and neighbours, including those who have stopped to admire our windows and ask who did them!

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.

We have used this company before so we know how reliable and helpful they are. Obviously the schedule was interrupted because of the lockdown situation but we were kept informed about when the business could resume and we were given a new date as soon as possible. We were not disappointed, the work was done to a very high standard. Timekeeping was excellent and not a moment of the day was wasted. The room and outside area were left tidy and clean. I would have no hesitation using the company again.

The guys did a brilliant job... such careful work and attention to detail. They could not have been better. Felt the difference in the heat in the lounge immediately and the windows look great. Thank you so much for a very efficient, excellent job.
