10 replacement wood framed, double glazed windows for a 3 storey Edwardian house

All went exactly as Derwent said it would. A large team took 3 days from start to finish (supported by copious quantities of tea and biscuits from the customer). The workmanship of both the windows and fitting has been excellent. Particular mention must be made of the young joiner who did some great work rebuilding sills and internal surroundings. The team left the house totally clear of all dust, rubble and other mess the re-fitting process creates. They were friendly, organised and professional and left very little retouching of the paintwork to be done both inside and out. We now have windows that are secure, easy to open and keep clean and look very much in keeping with the architecture of a house now over 100 years old. We still have a few more windows to replace and will certainly be going back to Derwent to get them done.

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.

We have had all of our external windows and doors replaced by Derwent in 2 phases over the last couple of years and honestly couldn't recommend them highly enough. Great people to deal with, attention to detail and quality of materials is excellent, no sense that the job needs to be rushed so the fitters aren't unduly stressed so they can do their job properly and to a standard that they are content with. No hidden extras; in our experience the price given is honoured even if unforeseen difficulties are encountered during the work, and if it takes a little longer than anticipated to get the job right then that is what happens. We spoke to several mainstream companies and also local suppliers before settling on Derwent - the level of info they provide in their quotation is above and beyond that provided by anyone else. Others varied from 'the back of a fag packet' to tons of paperwork which actually gave very little detail of what was actually being provided, and of course followed by the 'hard sell'. We got none of that from Derwent. By the time the work was finished saying thanks and goodbye to Ian, our prime fitter throughout, was like bidding farewell to a good friend! The problem we have now is that our soffits, fascias & gutters need to be replaced to match but they have set the bar so high its going to be difficult to find a company with equivalent standards. Of course they are not the cheapest but that really depends on where your priorities lie - price or quality?

I cannot recommend Derwent Windows highly enough, the service is excellent from start to finish. I had a beautiful cottage door fitted by Dougie, who was extremely polite & helpful. The door was made exactly how I requested & nothing was too much trouble. I would not hesitate to use them again.

The service from Derwent Windows & Doors was very professional but also friendly from the initial inquiry all the way through to the installation and after sales care. We really love our Aluco Aluminum crittal doors and they look stunning as part of a full renovation of our dining room, living room and conservatory. Highly recommended.

We had a 'Timber Windows' front door with side panels and top light, a back door and an Evolution casement bathroom window fitted. The quality of the windows and doors was second to none. I had obtained quotes from other companies and although Derwent windows were more expensive than most, you definitely get what you pay for and I am so glad that I decided to use this company. Customer service was friendly and efficient and Jan was extremely helpful in answering my questions and making changes to my order along the way as I kept changing my mind! The fitters were friendly and professional and worked hard to get the job done. They created very little mess and tidied up after themselves. They removed our old doors and window very carefully avoiding any damage to external render and internal decoration. All in all we are delighted with the finished result.

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.
