Derwent Sash Windows Ltd t/a Derwent Windows and Doors

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!
