What Our Clients have to say

From start to finish the company provided excellent customer service. They were meticulously clean as they covered all the furniture, curtains and flooring and were careful to remove it afterwards. The fitters Ian and Dan were consummate professionals. They kept me informed and involved me at every step. They were courteous and polite. There were a couple of minor issues which they resolved straight away. They went above and beyond to ensure that I was happy reviewing every window that they fitted with me. Would definitely recommend this company again as they made the whole experience as easy as possible from start to finish.

We had seven hardwood sash windows and a set of orangery doors replaced by Derwent Windows this month and have been delighted with the finished product and the quality of service throughout the entire process. The fitters were extremely professional and hardworking, and despite having to contend with heavy rain throughout the installation, our house and driveway were left spotless after each day's work. I would not hesitate to recommend this company to anyone looking for quality replacement windows, and we have already requested a further survey for additional work at our house.

From my initial contact with Derwent Windows right through to the finished installation they have been totally professional, knowledgeable, courteous, and efficient. I had many discussions with Derwent about how best to achieve my desired result, and nothing in the whole process was too much trouble for them. They always answered my many queries, discussed all my options, and tailored a package to suit my specific needs. Once the window specifications were agreed they were manufactured and delivered on time and fitted to an exceptionally high standard. The professional fitter's dust-sheeted everywhere, and on completion cleaned up leaving no trace of ever being there. The windows are of the highest quality and beautifully installed. Everyone with whom I dealt at Derwent Windows has been brilliant. They made the whole process stress free, and I would absolutely recommend them to anyone looking for truly excellent customer service, highly trained professional staff, and a superb end result. Thank you, Derwent Windows!

We had our old UPVC windows replaced with timber casement windows from Derwent. Their customer service from visiting the showroom to the finished windows is first class, everything from a deposit protection policy to polite, skilful & tidy fitters. The timber windows look great and make such a difference. We would highly recommend Derwent to anybody looking for new windows, it's exactly how a company should be run but so few are.
Customer in Nottinghamshire 08/04/2019

We have used Derwent Windows on two occasions, with the front windows replaced a few years ago and the remaining back windows and back door this year. The service and attention to detail has been absolutely first class from initial contact to final fitting. Every single member of the team has gone out of their way to ensure that we had exactly the outcome we were looking for, with replacement sash windows and replacement stone cills on our Victorian property. The fitters were prompt, friendly, tidy and flexible. The surveyor was thorough and accurate. The sales team in the showroom were professional and knowledgeable, with clear communication throughout. If you are looking for a local company with expert knowledge and a commitment to excellence, go to Derwent Sash Windows.
