Derwent Sash Windows Ltd t/a Derwent Windows and Doors

We've had four new windows in our post war semi detached house replaced with Evolution flush windows from Derwent and couldn't be more pleased. We didn't want that brilliant gloss look of what many people have have when they get new windows. We wanted the traditional style. And now they look great. We've had a number of complements. The window cleaner says they look like wood! Yes they were more expensive but they're worth it. All dealings with Derwent windows staff was professional, efficient but friendly. I must mention the fitters who were excellent. Punctual, hard working, ensured everything in the room was covered and cleaned up everything. We would use them again when we look to replace our downstairs windows. Would strongly recommend the company.

We've had three sash windows replaced and new porch doors fitted by Derwent and we could not have been more pleased by the quality of the work or by the ease of the process. The quality of the workmanship was matched only by the professional manner in which the order was managed from initial contact, through various revisions to plans, to the actual fitting itself. They are not the cheapest but still very competitive given the quality of product and service they offer. We would recommend Derwent very highly.

I have used DSW to fit windows and doors on two Victorian properties. The products are of very high quality and the service is excellent. The windows were sensitively designed to fit the buildings ensuring a like for like finish. The fitters were polite and professional and work was completed with the minimum of disruption. I wholeheartedly recommend this company.

We are very impressed with the professional service of all the staff involved with this company. They have carried out an encapsulation of our old stain glass long stairwell window. The job was carried out in an excellent manner from start to finish. Would definitely recommend this company to anyone wanting a top notch job done by first rate staff.

Really professional company including the surveyors, office staff and installation team. Order to installation was only a few weeks and we're really happy with the work

We have just had Derwent Sash Windows replace all the doors and windows on our barn. Everything was first class from the product to the fitters who were very respectful of our home and attention to detail was exemplary Very highly recommended. Thanks Lads Geoff and Diane

Everything about having our new doors and sash windows fitted has been perfect. Right from the first visit to the showroom everyone has been really friendly and knowledgeable. The final fitted products look amazing and have been put in without any mess leftover (I've never known such tidy tradesmen). The guys have done a really good job and we couldn't be more pleased with how it all looks. Totally recommended from start to finish.

A brilliant job from start to finish from the whole team. Everyone worked very hard to give us the service and product we required.The attention to detail excellent. Thank you all very much. Highly recommended.

We are delighted with our new Solidor. From the start of the process to the end we have found Derwent Sash Windows to be an excellent company which has provided us with a very good service. They were able to be flexible when finding a time for installation and Dougie did a spotless job of fitting the door. We would recommend this company without hesitation.

We ordered 2 new wooden sliding sash windows to replace some which were badly made about 7 years ago by a local joiner, and also a fixed window which was rotten. We went to the showroom and looked at the windows which seemed to be good quality, and placed our order. The fitters came on the planned date, and even though we had cleared the area and put down dust sheets, they covered everything. The windows were fitted and finished in a day, they were very organised and tidy, and friendly. I would have no hesitation using Derwent Sash Windows again. We know that the 4 large sash windows on the front of our house will need replacing!
