Derwent Sash Windows Ltd t/a Derwent Windows and Doors

Derwent windows fitted bi-folding aluminium doors to our dining room, removing an old conservatory first. Their service was always highly professional, very friendly, and responsive and helpful when I had specific questions. Andy who came out to assess the work needed was extremely helpful and knowledgeable. The three men who fitted the windows - Ben, Mark and Ian - showed considerable attention to detail to get the fit right (given how uneven our Victorian house walls are). The few jobs that needed doing after the windows were fitted were all done promptly. I am delighted with the look and function of the windows and would use Derwent Windows again without hesitation. The quality of their service and aftercare makes them good value for money.

The work was done on the agreed date - helpful, pleasant workers. Needed to arrange a further visit to fill the remaining gap between the frame and masonry. This was completed and our job satisfaction was checked before the final payment was requested.

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!

We badly needed a new wooden front door for our old Victorian house but wanted it doing without the need to replace the original door frame. Another of our requirements was that the door was to have different internal and external colours and a different finish to the door fittings. Several firms had told us that this couldn't be done. We paid a visit to the Derwent showroom at Trent Bridge Nottingham who arranged for one of their staff to visit us to do an assessment. They said it was not a problem. From the first discussion through to the door being completed and fitted all the staff at Derwent were knowledgeable, punctual, professional, efficient and friendly. A special mention must go to Kim at the Nottingham showroom and Mark the fitter. We are extremely pleased with the result, the new door looks great. A big thank-you to all at Derwent.

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.

The whole end to end experience of using Derwent windows was excellent, from initial site visit, to survey, to installation. The fitters (Ian and Ben) were friendly, and thoroughly professional, explaining what would happen and when. They were a pleasure to do business with and the new windows are absolutely superb. I would wholeheartedly recommend the company.

Great company to do business with. End-to-end team were courteous, helpful and great asset to their employers. The quality of the product is exceptional and the installation team were outstanding.

First time we have used Derwent Windows and they were excellent from start to finish. We had two wooden sash windows installed to match the rest of the windows in our house. The fitters were prompt, polite and did a very professional job. They kept us informed throughout the fitting, regularly checking with us to make sure we were happy with progress and at the end made sure that everything was clean and tidy and to our satisfaction. We would definitely use them again and in fact I have just recommended them to a neighbour who saw our new windows and was very impressed

I have used Derwent Windows in the past and was pleased with the work they did, so when I needed a new door I was happy to go back. As before they were punctual and did a good job. I am happy I went back to them.

In my opinion, Derwent Windows ultimately decided to prioritise their own profit over doing the right thing by their customer. Only after damage started to occur was I told that either “damage is normal during an installation” or that the product I had chosen was “easily marked or damaged”. Both these statements were confirmed not to be true by Origin, the manufacturer, when I raised this with them. A refund was offered but the time to find another installer & start the whole process again wasn’t an option for me, due to delaying my renovation. Instead, I gave Derwent Windows the opportunity to make good any issues experienced. The Which? Trusted Trader approved Dispute Resolution process had to be taken to get the problem resolved. As the Chartered Surveyor started to come to his decision, Derwent Windows decided to settle my claim in full. After 21+ months of unpleasantness, I received a refund of over £2,100. The 10 year insurance backed guarantee has also now been received, which during this process, Derwent Windows attempted to withhold (even though as a FENSA member this is stated as being mandatory). The outstanding remedial work that was also agreed upon, has at this time after 4 weeks not taken place, this has had to be escalated to Which?. In conclusion, unless you know your legal rights as a consumer & are prepared to fight for them, I cannot recommend using Derwent Windows, as the experience has been extremely time consuming, stressful & unpleasant.
