Derwent fitted 11 sash windows into our Victorian house. We had seen other houses in our area fitted with their windows which have stood the test of time; Andy clearly explained the differences between products Derwent offered and was able to guide our decision-making. The whole process from start to finish has been top quality, as are the windows. Communication has been clear and courteous, all staff have been trustworthy and friendly, and the windows enhance our property. The budget and schedule were adhered to. I highly recommend Derwent Windows.

From start to finish the company provided excellent customer service. They were meticulously clean as they covered all the furniture, curtains and flooring and were careful to remove it afterwards. The fitters Ian and Dan were consummate professionals. They kept me informed and involved me at every step. They were courteous and polite. There were a couple of minor issues which they resolved straight away. They went above and beyond to ensure that I was happy reviewing every window that they fitted with me. Would definitely recommend this company again as they made the whole experience as easy as possible from start to finish.

We have just used Derwent Windows again to install more windows at our house, having been very happy with the first installation earlier this year.

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.

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.

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 had Evolution flush casement windows fitted as well as a new Timer Doors front door with side panels. The windows and door include encapsulation of the original leaded light stain glass windows. Dealing with the office at Derwent has been a pleasant experience from our first visit to the showroom through to completion of fitting. Likewise, all the fitters who have been out to the house have also been very extremely friendly, professional, and helpful. We are very pleased with the quality and appearance of the products and have received many complements from neighbours, visitors, and passers-by! We would have no hesitation in ordering from Derwent again in the future.

A spectacular improvement to our house

We can't rate Derwent Windows highly enough. They conducted the initial site visit and provided wisdom and expertise about what our house may have looked like originally to help choose the right products. He was very patient while we looked at different options and we felt able to trust him. They then coordinated surveys and commissioned builders for us to do lintels and stonework. All calls and appointments happened when they were agreed, no issues and any sticking points were talked through clearly. Everyone in the office organised the quotations and final details without any fuss or mistakes. Then the builders and fitters did an absolutely superb job - we have had multiple comments from neighbours and passers by about what a great improvement and how sympathetic the new windows are. They are quality products that look set to last. We are very glad we trusted Derwent with this work.

Rob and the team from Derwent Windows have designed and built us a superb orangery. The team have been consistently hard-working, punctual, and professional throughout the process. Rob has site managed the project throughout. He has always kept us informed at each stage of construction, providing daily updates. The finished build is outstanding in quality and beyond our expectations. This is the third time we have used the company and would not hesitate to use them again in the future.
