Derwent Sash Windows Ltd t/a Derwent Windows and Doors

We had 16 windows replaced in our old Farmhouse… not easy feet as everything is on the “wonk”. From the initial call, to Emily’s site visit, the visit from the surveyor, trips to the show room and the two fitters we would not have one grumble. Everyone was lovely and helpful. Couldn’t fault them. The fitters attended and worked so hard every day in the freezing cold without a complaint about how much of a tricky fit our windows were. Everything was left clean and tidy, they were a pleasure to have here for the 4 days. I wouldn’t hesitate to recommend Derwent. Thanks so much!

I am starting to replace double glazing that was installed 25 years ago and, after visiting their showroom, I decided to employ Derwent Windows. I could not have made a better choice. The showroom staff were very knowledgeable and helpful. Callum, the installer, was extremely careful and did an excellent job. I would not hesitate to recommend Derwent Windows and hope to use their services again in the near future.

From start to finish Derwent windows provided excellent service - we could not fault them. We had 9 replacement windows fitted in an old cottage, including some brickwork to replace an old wooden panel. The sales team were very helpful in helping us choose the right windows, handles and replacement reclaimed bricks for our property. We were kept well informed of the timescale. The friendly, polite fitting team worked incredibly hard, and never once complained about the fact that our drive was too narrow for their vans so had to barrow everything several hundred yards to and from the house. Everything was left clean and tidy and we are delighted with our new windows.

We have had a patio door installed by DERWENT Windows and are extremely pleased with their service from beginning to end. All the initial paperwork and discussions were completely straightforward and efficient. On the day of installation the two fitters arrived promptly and commenced their work. They were very polite, conscientious and efficient. On completion everywhere was left clean and tidy both indoors and outdoors. If/when further window replacements are required we would not hesitate to use DERWENT Windows again. Thank you to the total team 😊

We had 2 sets of wooden doors installed. The doors are of a high quality and heave been installed very well. The old doors were taken away and there was no mess left behind. The installers were very courteous and respectful of our property. I would definitely recommend Derwent Windows.

Have used them before and been thoroughly satisfied with their work. This time it was my bathroom window and back bedroom window. Everything went very smoothly and professionally but with a friendly manner from the surveying and measuring of the windows, to their efficient office folk in communicating with me, to the installation by their experienced fitters. Really pleased with the final results and would definitely recommend them highly.

The service was excellent from the start. Highly efficient process from initial inquiry to completion of installation. Product very good quality but what was exceptional was the installation. The two guys who came were highly professional, caring and accommodating. They did an exceptional job and would recommend them to anyone.

We had 17 of our windows replaced using Derwent uPVC double glazed panes and 16 panes encapsulating stained glass windows. The windows we are delighted with, and we were very happy with the installation team who were on site for 2 weeks. Derwent were responsive to our concerns re dust and disruption and covered all furniture well. We had up to 5 installers on site at any one time; they were always courteous and respectful of working in our home. All in all, we have been extremely happy with the windows and the job done to install them. Highly recommended. After care so far is good, and any minor issues we have had have been resolved without hassle.

After experiencing a poorly fitting upvc front door for a number of years we decided to bite the bullet and do the job properly. From visiting the showroom at Trent Bridge and meeting the lovely staff there, through the assessment visit, then fitting, then final tidying, and including communications with the main office staff, the process has been a revelation. We are so used to being slightly disappointed with things to do with houses and building, that the experience we have had has surprised us. First of all, the quality of the door, first rate, and so it should be for the price, but the skill of the fitting of the curved frame in a 250 year old house that has been bashed about over the years was remarkable. Secondly, they really knew what they were doing, both at design stage, manufacture and fitting, as we were worried that the delicate external render was not damaged. This was achieved effortlessly. The final fitting to make good skirting was also excellent and had to include them ordering a unique profile. To sum up, if you appreciate the best, both in product and service, and realise that these values need to be properly paid for, then contact Derwent.

We live in an old Coach House in the High Peak and needed to replace some old single glazed windows, choosing a mixture of timber look (uPVC) and wood. Derwent were recommended by our neighbour, we had 3 quotes, all similar but Derwent gave the best honest advice in their showroom and weren’t pushy. Andrew was also really pleasant and helpful when they came round to check measurements and finalise details. Fitting was arranged at a convenient time and changed with no problem when we booked a holiday. The fitters Ian and Mark arrived on time, it didn’t start well, they said they would probably not be able to fit one of the windows and have difficulty fitting the other 2, this may have been why these windows were original and had never been replaced. They did figure out a solution and worked hard all day to finish the job and were both really nice guys. The windows are excellent quality and look fantastic in place. Although we chose a slightly more expensive wooden window at the front to closer match existing, the uPVC ones are almost identical. Ian and Mark were fastidiously tidy and despite the challenges of removing and replacing the windows there was no damage to the interior or exterior of the property. If at sometime in the future we replace the other windows we would definitely use Derwent.

Having used Derwent Windows for a number of projects last year we had no hesitation in using them to replace our old windows with new UPVC sash windows. From the initial surveying, quotation and planning stage through to the fitting of the windows we found the staff to be very professional. We were especially with the care and attention to detail of the wooden architrave finishing to the windows, not straight forward in an older house. We would not hesitate to recommend this company to you.

The team from Derwent were on-site as planned, they completed the work on schedule and to a high standard both inside and out. Where some restoration work was required they completed this to a high standard and dealt with any unexpected issues that cropped up.

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.

The workmen arrived when expected and were polite and friendly. They got on with replacing our front door efficiently and asked us to check where door furnishing were required. We are happy with the look and the quality. It feels very solid and secure. And looks really good. The only surprise was that there was no re-confirmation of the due date for fitting by email or phone. I had to make the call as it had been booked quite a way ahead. But was only a little concern.

Living in a Conservation Area we thought long and hard about UPVC windows. After much research we came across Derwent in 2018 and they have replaced most of our windows, both casement and sash, in stages over the past six years. We have been extremely happy with the quality of the windows and the workmanship. Any minor snags have quickly been dealt with. The staff are all very pleasant and I would have no hesitation whatsoever in recommending this company.
