Derwent Sash Windows Ltd t/a Derwent Windows and Doors

Decided to replace 2 doors and 2 windows including our front door..Viewed the products at a local showroom and obviously they were of very good quality.The surveyor was very experienced and was able to answer all our enquiries.Long lead time for manufacture but we were very pleased with the quality once fitted.The fitters were excellent working hard throughout the day despite heavy rain even refitting Venetian blinds afterwards which we thought we would have to do. Although they inadvertently cut through a telephone cable which both we and they thought was redundant when it turned out it wasn’t they successfully repaired the severance. Overall very happy with the product and extremely happy with the fitting.

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.

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.

We were so pleased with the doors, French windows and windows they fitted in the summer we asked them back to install some more. Superb product, skilled and friendly workforce and competitive price (you get what you pay for). The customer service and caring attention to detail second to none.

Derwent windows initially installed 2 new French doors for us in April and we were so pleased with them that we went ahead and asked them to replace all the windows in our house which were in a sorry state. We were rather anxious as it was such a big, expensive job but we couldn't be happier with the finished result as our new windows are not only beautiful in appearance but they have made the house much more soundproof, warmer and secure. The whole job was completed within the 2 week schedule and the timekeeping of the window team was excellent. They were friendly, respectful and professional throughout and there was minimal disruption during the job. It has been a pleasure to deal with a company who not only have first rate products but also have a good team of window fitters to install them. Our thanks to the Managing Director Rob and all his team on a first class installation.

We had our windows replaced in 2019 and have just had front and back doors fitted. Windows and doors have been admired by friends and neighbours.Derwent Windows on both occasions were helpful throughout from the planning and drawing stage through to the final fitting. Everyone in the company has been very professional and a delight to deal with. I would certainly recommend this company.

We had several windows replaced by Derwent Windows in 2020 and have just had another window replaced. Excellent service as before, with good communication. Work was carried out on agreed date, very efficient and careful installers. Very happy with the result. Would definitely recommend.

We had six sash windows replaced by Derwent Windows in an old property in a Conservation area , the Team at Derwent Windows were brilliant from start to finish , communication and workmanship was excellent throughout the whole process we will definitely use them again . Thank you

We live in a conservation area, so planning permission was needed. Derwent Windows we’re helpful and knowledgeable about the whole process. From our first showroom visit to installation we found all staff professional. All deadlines were met, the installation went smoothly with care taken working around garden plants and tidying after. We are very pleased with the finished job, the sash windows look fabulous and no painting! We will use Derwent Windows again and would not hesitate to recommend the company.

After a couple of our neighbours had used Derwent Windows we decided to contact them and enquire what they could do for us. What an excellent experience from start to finish. Not just the range of window options, but the attention to detail, the communication process and of course the fitting of the windows. One particular point to note was the quality of the window fitters. They were an excellent bunch of guys. If anyone asks about our windows we have no hesitation in recommending Derwent Windows.
