High quality product & craftmanship

We had a solid wood sash window replaced by Derwent Windows. The quality of the product is top rate & the fitters did an excellent job, very thorough, polite & exceptionally well cleaned during & at the end of the job. The time from order placed to fitting was very considerable , but that is the same very where I imagine. They are not the cheapest windows on the market, but I would rather pay a premium for the product quality & craftmanship. I would definitely use again & would recommend Derwent Windows

Derwent Windows provided the best customer service we have ever experienced. They were extremely helpful, very professional and the standard of work from the fitters was outstanding. Whilst the windows are not the cheapest, the quality is high and we would definitely choose them again.

Derwent replaced 16 of our Sash and casement windows on our Victorian house. From start to finish they have been very easy to work with and are the opposite of a hard sales window company. There work is second to none and we are really pleased with the windows we have had so many compliments already. They aren’t the cheapest on the market however they are worth every penny to know we have had the best job done. Would highly recommend and will be using them again when we have our extension.

Beautifully manufactured sash windows. The installation team were top quality. Our builder was really impressed by the professionalism of the team who obviously took a real pride in their workmanship. Our builder had experience of other suppliers but was completely blown away by the quality and value of our Derwent Windows. If you're replacing sash windows checkout this product!

Derwent Windows replaced around 20 windows in our 1904 Edwardian maybe 8 years ago, superb job, superb team. Most were sash windows, conservation area etc The door was 1904 and falling apart. Went for the proper door, they fitted it in a day, their staff are craftsmen.

Traditional casement windows

We had two traditional casement windows fitted to the front of our house to replace existing windows, which were pretty much beyond repair. From start to finish the service we received was excellent. Options and costings were explained clearly and communication along the way couldn’t have been better. Very satisfied. Good company to deal with and would use them again.

This company has now undertaken installations at both my current and previous properties, in all, several stunning window and door projects over the past 10 + years. The work just completed (December 2023) required feasibility advice on the installation of brand new floor-to-ceiling timber windows in alcoves to either side of a fireplace. From the initial survey and valued technical advice, to ordering the bespoke timber products, and finally the skilled building work undertaken by the superb in-house team, everything went to plan - and looks fantastic.

I had a number of windows replaced by Derwent earlier this year. Being completely satisfied with these I asked if they could replace two more which were so inaccessible that I fellt that it would be prohibitively difficult. Andy the surveyor deemed it possible and Ian and Rob did a brilliant job under very difficult circumstances.
