Derwent Windows fitted a new front door for us. They were helpful and kind throughout the whole process. From the initial estimate to design details and the final fit, they have been great. We are very pleased with our new front door!

We had a replacement hardwood front door and surrounding frame and stained glass encapsulation. The original stained glass windows were removed about a month prior to fitting. Expertly removed and our home securely boarded up. We are delighted with the finished product. The original stained glass and leaded window has been carefully cleaned, repaired and encapsulated and looks amazing. The new front door is also of a really high quality and finish. The fitters removed and fitted the new frame, window and door in a day, with minimal fuss. We were consulted throughout the fitting on minor details that needed a decision . We contacted Derwent Windows the following day about a small issue we had found and it was promptly dealt with. Highly recommended for quality of product.

We recently used Derwent Sash windows to install Origin bi fold doors and windows. Their professionalism and customer care are excellent. All the staff that we dealt with have been very helpful and efficient. The doors and windows look outstanding and have completely exceeded our expectations. Particular thanks must go to Alister, Andy and Jan who are a huge asset to the company and have stayed in touch constantly throughout the ordering and installation process. Also the professionalism of the installation team and cleanliness in their work was equally as impressive. We also had between the glass blinds fitted by Derwent Sash windows and these really show the quality of the doors and windows. We are extremely impressed with this company and wouldn't use anyone else.

Our new sash windows look just right in our 1900s town terraced house, matching the style and exceeding the quality of the original ones. The service from Derwent Windows was expert, appropriate and on time. Attention to detail was given at every stage of the process, so that the resulting windows look fantastic. Thank you.

Premium quality windows, doors & installation team

We had all the windows and doors replaced. We chose Derwent windows because they supplied Evolution windows which I considered to be the best on the market. The price was the price and non-negotiable but we considered this a positive after dealings with other National firms who's starting prices were frighteningly high followed by pressurised negotiations! Derwent were very helpful with choosing and detailing, but some confusion arose because we talked to four people, this was resolved when we asked for one focal contact (hence the 4 star rating). The installation team were fantastic, polite, helpful, covered everything with plastic sheeting and no problem was too small. All snags were resolved to our complete satisfaction.

Very high standard of workmanship. Beautifully made and fitted door and windows. They even opened up the old fanlight over the door, which had been bricked up years ago. The plastering afterwards was of a very high standard too. Courteous and prompt service. I would recommend highly to anyone in this area.

Arched Front Door

Our new front door has been long anticipated and we are thoroughly delighted. The Derwent windows showroom is worth visiting to visualise the quality and range of products available. The staff are exceptionally helpful and the whole team is absolutely delightful. This is a full package with complete attention to detail. We had 3 site visits to plan, design and measure the door, we had books and samples which allowed the whole family to contribute their opinions. The office staff were supportive and available throughout the process, ready to answer queries via telephone and email. On the day of fitting the men were prompt and did a beautiful job. We could not be more pleased. Perhaps it's a sign of my age that I have taken a photo of my new front door to work with me? I recommend this company and we will certainly use them again.

Changed all of the windows in our house and have to say this was the one of the best customer experiences I've ever had. The owners and workers are courteous and considerate and completely customer focussed. They bend over backwards to make sure you are happy. They made no mess and finished very quickly. I have full confidence any aftercare we would need if any problems should arise. This is how every company should operate. So glad I went with these guys. I wholeheartedly recommend them.

Everything went very smoothly from the search for what we wanted, deciding upon a design, ordering and paying for two sash windows. They were installed with the minimum of disruption, on the day appointed and within the timescale suggested. The installers were all very helpful, covered all surfaces on the stairs and in the rooms where the windows were to go, worked tidily , left things clean and were even prepared for the rain that fell. good follow up and attention throughout the whole process.
