Derwent Window and Doors Ltd

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 hard working, 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.

The work was carried out to time and high standard. The workmen were polite and kept everywhere as clean as possible during the work and cleaned up when they finished. We were delighted with the high quality of the door and frame and the way it was finished and fitted. We were kept informed throughout from ordering to delivery and would highly recommend this company.

After Derwent replaced our front windows about 10 years ago - a job we were very pleased with - we decided to use them again to replace our ageing rear windows with wood-effect uPVC (in our opinion, it looks just as good as painted wood, and there is a lot less maintenance). We made 2 or 3 visits to the showroom, where there are comprehensive displays of all the ranges they sell. They deal only in high-quality frames, so this is not the firm to use if you are looking for cheap double glazing. Service throughout was helpful and courteous, with good and frequent communication by e-mail and phone. One window required stained glass, and they directed us to a local expert company to choose the glass colours. The installers work long days and just get on carefully and expertly with the job, including moving and protecting furniture etc., and cleaning up at the end of each day. We are very pleased with the appearance and quality of the finished installation. A courtesy call from Andy today to ensure we were happy was a nice touch.

Derwent Sash Windows recently installed new sash windows to the front bedrooms of our Victorian terraced house. Their team, from initial consultation to completion of work, was excellent throughout. The windows are superb and met the local council's planning requirements for the conservation area. We would definitely recommend them.

I had 5 replacement sash windows and front and back door. I am absolutely delighted with them. They look amazing. I had a few quotes in and Derwent stood out by a mile from the start. Definitely recommend a visit to the showroom. The fitters did an excellent job and clearly take a pride in their work. Would rate 10/10

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.

Derwent fitted 11 sash windows into our Victorian house. We had seen other houses in our area fitted with their windows which have stood the test of time; Andy clearly explained the differences between products Derwent offered and was able to guide our decision-making. The whole process from start to finish has been top quality, as are the windows. Communication has been clear and courteous, all staff have been trustworthy and friendly, and the windows enhance our property. The budget and schedule were adhered to. I highly recommend Derwent Windows.

We cannot recommend Derwent highly enough. Every aspect of the work carried out renovating a number of large stained glass windows in our late Victorian house was excellent: quality of the product, craftsmanship, efficiency and cleanliness of the installation, and customer service throughout the project. Advice and guidance, and communication from the Derwent team were also outstanding from initial discussions to completion.

We had a front door fitted in January and have been very pleased with the standard of care throughout the process. The quality of the goods is excellent as is the skill of the fitter, Dougie, who made a super job. We are delighted and will use the company in the future.

Brilliant company from start to finish cannot commend them enough. The windows have totally transformed out property. The workmanship was brilliant and the fitters worked tidy and efficiently and are a credit to the company. Safe to say we will be using them for the other bits we plan to have done.
