Fantastic service from start to finish

Large project of over 40 windows/doors/bifold etc with differing styles from traditional sash at the front of the house to a more contemporary design to the rear undertaken through 4 phases of work over a three years time period and the customer service levels, professionalism and quality remained at a high level throughout this period. A lot of support around getting the correct specification from numerous meetings, use of the showroom and the prompt return of calls/enquires to clarify the smallest detail and the level of patience/support during the various project time periods was key. As the project was conducted over 3 years and four phases we had a wide selection of team members as well as some familiar faces working at our property but all set very high standards in terms of professionalism, cleanliness and quality of work. Snagging was a breeze as the team had already completed their own snagging list and kept us fully informed throughout the phase of each project. Just remains to say thanks and would highly recommend.

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.

They fitted two double-glazed sash windows quicker than expected and on budget. They hit a problem with some old electrics in the house and resolved it quickly with no inconvenience or delay. This is the third time we have used Derwent and they are always polite, professional and respectful of the house which they leave in immaculate condition.

They replaced a bay window and two bedroom windows. Very professional, high quality installation carried out quickly and tidily. We will be having them back to replace the remaining sash windows next year. We would recommend them to anyone.

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
