We have used Derwent Windows on two occasions, with the front windows replaced a few years ago and the remaining back windows and back door this year. The service and attention to detail has been absolutely first class from initial contact to final fitting. Every single member of the team has gone out of their way to ensure that we had exactly the outcome we were looking for, with replacement sash windows and replacement stone cills on our Victorian property. The fitters were prompt, friendly, tidy and flexible. The surveyor was thorough and accurate. The sales team in the showroom were professional and knowledgeable, with clear communication throughout. If you are looking for a local company with expert knowledge and a commitment to excellence, go to Derwent Sash Windows.

I am delighted with the high quality of my new front door as well as the quality of the fitting. The fitter took time to make the surround look very neat and well finished. When fitting was completed the site was left very clean and tidy. I have no hesitation in recommending this company, as all staff were both helpful and polite at all times.

Had a new door fitted. Derwent were helpful from the very first time we stepped into the show room. The door was installed ahead of schedule and the quality is first rate. The fitters were excellent throughout, leaving zero mess and doing an excellent job. A follow up call was made to us to check satisfaction. Would definitely recommend this company to anyone.

Delighted with our new front door and side panels, the service was first class from start to finish. The showroom staff were very knowledgeable and helped us with any questions we had, nothing was too much trouble. The team kept us informed through the whole process. We chose a wooden door and wanted to retain the original 1930's stained glass, they were able to arrange for the glass to be removed, cleaned and glazed and then placed into our chosen door, it looks fabulous!! The fitter was very professional, a skilled fitting all round with no mess. Totally satisfied with the quality and value of the door and the fitting and would highly recommend Derwent Windows and Doors.

We were impressed with the whole process of buying our new windows, from the staff in the showroom, the surveyors, and the fitters who worked very hard and did a very professional job. They were all a pleasure to do business with. The windows are a fantastic quality and we would definitely recommend both the make of window and the Derwent Windows team.

New French Doors fitted. They were there at 7.30 and finished by 10.00. We got home from work and the only way we could tell they had been, was the new doors. No mess that we could see at all. Good price comparing it to other quotes and we had a courtesy call a couple of weeks after the work to make sure we were happy with it. I have no problem recommending them and would be happy to use them in the future. Phil and Sharon, Ripley.

I was absolutely delighted with my sash windows and 2 new doors for the renovation of my Victorian property. The whole end to end experience was a pleasure. Everyone at Derwent was so helpful and nothing was too much trouble. The finished work is beautiful and I've had so many compliments. Thank you so very much everyone. I would highly recommend Derwent.

Derwent Windows came when they said they would, they prepared each room in turn with thorough dust protection and worked in a brisk and professional manner. The staff were friendly, co-operative and extremely professional. The finished product looks very impressive and the sound and heat insulation is much better than the old and compromised original double glazing. They were not cheap but we felt they were well worth the money. Elizabeth

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!
