Excellent company- to be highly recommended!

Derwent are not the cheapest company, but now I would use none other for windows and doors. The whole team are highly professional and nothing was too much trouble for any of them. This was apparent from the beginning to the end of my dealings with them- from my first visit to the lovely showroom, the visits from Alister and then Andrew, the surveyor, to the hardworking fitters themselves- all were great and Douggie was a star when he came back to fit my front door! The service from the office staff was equally good. I had Evolution flush windows and a timber door fitted at my home. I am absolutely thrilled with them and they look great. Additionally, the difference in sound reduction and heat retention is amazing. I have since had a front door fitted at another property and my tenant is thrilled with it too. I would highly recommend Derwent and if you are looking for good quality products, efficiently and professionally installed, you cannot go wrong with this company. Thank you all!

Best backdoor ever

We ordered our backdoor through Derwent Sash Windows. We didn't look elsewhere because visiting their showroom we knew that they would do a good job, at a reasonable price. It was evident from their customer service which was authentic and honest. Prior to the install, the measuring up was completed quickly and with friendly staff, and on the day of installation it was a joy to chat with such a great fitter. He did a perfect job in awful weather. I can't believe how clean the job was! We'll definitely get the rest of our windows and doors from here.

After visiting the showroom, my partner and I were blown away with how professionally it is all set out, with first class personal customer service, with the team there listening to what we wanted as opposed to telling us what they could do ..... overall very impressed.... Which carry's on with the final fitted product. The fitters who installed really took attention to detail as their main objective ..... We are both very pleased, and will be having the windows installed by Derwent in 2018.. I can highly recommend Derwent Sash to anyone ....

Absolutely delighted with our new sash windows from Derwent. The products are first class. The fitting team were brilliant, preparing each room with plastic sheeting before fitting. Outstanding service all round highly recommended.

All brilliant - windows, fitting and team

From the first visit to their showroom right through to completion the whole process was professional, easy and surprisingly quick. The team who fitted our windows and doors were brilliant - so little mess, covering every room in plastic sheeting and vacuuming up each evening. The finishing little touches set them apart and the finish is beautiful. We are so pleased. They arranged a builder to knock two windows into one which went really well. The plastering and stonework is spot on, you'd never know there was two windows there before. Highly recommended. Thank you.

We wanted two doors replacing with upvc that did not look plastic. DSW supplied and fitted them. They knew their products so we got exactly what we needed. Kept us informed on progress of the order and fitted them on the day they said. Workmen were very good, covered everything up and cleared up. Excellent job, just what you want. Always worth searching for a trusted trader.

We recently bought a house with some of the windows complete and want to finish them all. From the original quote through to the completion of the first window last week the process has been smooth and professional. the workmen were on time and the quality of their work, which included building work, was excellent. We'll be back soon as there are 6 more windows to go.

Great new windows

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.
