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 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.

Well, what a joy, what an experience, what a result. 'Period Orangery' built in 3 months to a high specification with large sash cord windows and lantern with tumbled facing bricks from north cot brick with fabulous Aluco doors linking to the main lounge. Derwent during the build period never missed a beat and their quiet focus on the quality of work and detail was ever-present. Beyond being built to architectural with this level of focus I was very proud to be part of the team. Anticipating a Jaguar, we have built a Bentley.

We have recently had a brand new front door and stained glass top light fitted at our new house and we are delighted with the quality and look of the product and fitting. The communication after visiting the showroom was good and whenever I needed to call for an update and I could get straight through and speak to the person handling our order. We had a little hiccup along the way with some of the glass being damaged during removal however I cannot fault the service provided in response to this to get it resolved and we have ended up with an even better toplight as a result. Everyone we dealt with was professional and friendly the fitters workmanship is top quality. Overall, we are delighted with the door and service provided. I would 100% recommend.
