Derwent Sash Windows Ltd t/a Derwent Windows and Doors

All went exactly as Derwent said it would. A large team took 3 days from start to finish (supported by copious quantities of tea and biscuits from the customer). The workmanship of both the windows and fitting has been excellent. Particular mention must be made of the young joiner who did some great work rebuilding sills and internal surroundings. The team left the house totally clear of all dust, rubble and other mess the re-fitting process creates. They were friendly, organised and professional and left very little retouching of the paintwork to be done both inside and out. We now have windows that are secure, easy to open and keep clean and look very much in keeping with the architecture of a house now over 100 years old. We still have a few more windows to replace and will certainly be going back to Derwent to get them done.

We had Evolution flush casement windows fitted as well as a new Timer Doors front door with side panels. The windows and door include encapsulation of the original leaded light stain glass windows. Dealing with the office at Derwent has been a pleasant experience from our first visit to the showroom through to completion of fitting. Likewise, all the fitters who have been out to the house have also been very extremely friendly, professional, and helpful. We are very pleased with the quality and appearance of the products and have received many complements from neighbours, visitors, and passers-by! We would have no hesitation in ordering from Derwent again in the future.

We have had all of our external windows and doors replaced by Derwent in 2 phases over the last couple of years and honestly couldn't recommend them highly enough. Great people to deal with, attention to detail and quality of materials is excellent, no sense that the job needs to be rushed so the fitters aren't unduly stressed so they can do their job properly and to a standard that they are content with. No hidden extras; in our experience the price given is honoured even if unforeseen difficulties are encountered during the work, and if it takes a little longer than anticipated to get the job right then that is what happens. We spoke to several mainstream companies and also local suppliers before settling on Derwent - the level of info they provide in their quotation is above and beyond that provided by anyone else. Others varied from 'the back of a fag packet' to tons of paperwork which actually gave very little detail of what was actually being provided, and of course followed by the 'hard sell'. We got none of that from Derwent. By the time the work was finished saying thanks and goodbye to Ian, our prime fitter throughout, was like bidding farewell to a good friend! The problem we have now is that our soffits, fascias & gutters need to be replaced to match but they have set the bar so high its going to be difficult to find a company with equivalent standards. Of course they are not the cheapest but that really depends on where your priorities lie - price or quality?

I cannot recommend Derwent Windows highly enough, the service is excellent from start to finish. I had a beautiful cottage door fitted by Dougie, who was extremely polite & helpful. The door was made exactly how I requested & nothing was too much trouble. I would not hesitate to use them again.

The service from Derwent Windows & Doors was very professional but also friendly from the initial inquiry all the way through to the installation and after sales care. We really love our Aluco Aluminum crittal doors and they look stunning as part of a full renovation of our dining room, living room and conservatory. Highly recommended.

We had a 'Timber Windows' front door with side panels and top light, a back door and an Evolution casement bathroom window fitted. The quality of the windows and doors was second to none. I had obtained quotes from other companies and although Derwent windows were more expensive than most, you definitely get what you pay for and I am so glad that I decided to use this company. Customer service was friendly and efficient and Jan was extremely helpful in answering my questions and making changes to my order along the way as I kept changing my mind! The fitters were friendly and professional and worked hard to get the job done. They created very little mess and tidied up after themselves. They removed our old doors and window very carefully avoiding any damage to external render and internal decoration. All in all we are delighted with the finished result.

We had our wooden sash windows replaced with new ones. The work was carried out to a very high standard. On Time, Clean and Tidy and Very Polite. Would definitely recommend.

We have recently had a wooden stable door fitted in a stone cottage, by Derwent windows . This is a very good product from timber windows. Dougie the installer arrived promptly as arranged, the installation was first class in very poor conditions. Not the cheapest door available but the total service make this worthwhile. Highly recommend and would use this company again.

We have recently had the windows on the front of our house replaced by Derwent Windows. Callum and Ben were first rate fitters. They worked incredibly hard with attention to detail. They left the site spotless. We have used the company before and will use them in the future. The quality of the Windows is excellent. Thank you Derwent!

Derwent Windows was initially recommended to me by my neighbours who had had all their windows replaced and were very satisfied. From this recommendation I had 2 windows replaced a couple of years ago and was more than happy with them. I have now had a replacement door to the balcony with a top window fitted this week. I'm delighted. There was quite a delay from ordering the door to it being fitted but in this Covid year that is no surprise. The 2 fitters did an excellent job and left the room very clean and tidy. I was shown very carefully how to operate the locks and I was impressed by how careful the fitters were in protecting the stair carpet. The products aren't cheap but the quality is excellent.

We went with Derwent windows because my parents had all their windows and doors fitted by them and was extremely happy and couldn’t speak highly enough of the service from the business owner to the fitters. After my parent's house was finished most of the other houses on the street had doors or windows from the same company just because they saw what a good job they’d done. We only had the front and rear door replaced but from looking around the great showroom they didn’t pressure you and was all very friendly and knowledgable. After we decided what we wanted it was emailed to us how the doors would look and the cost. The fitter was fantastic and a credit to the company, Really friendly, didn’t rush and did the job to the highest standard. Before he left both him and the owner of the business asked if we were happy with the job. Without doubt, if I need anything else or anyone asks who they should use for this sort of work I’d 100% recommend Derwent windows.

We would highly recommend this company, as they work to a very high standard, along with having excellent communication before, during and after the job. We had our upstairs window enlarged to accommodation bi fold doors, which has created a fantastic space, which we are thrilled with. Everyone involved was polite, and respectful, especially so in the the current circumstances relating to the Covid pandemic. We cannot recommend them enough, as we have used to company for many years now, and have always been pleased with the outcome.

Not cheap and pitched as a top of the range product we bought 6 sash windows and an external door for an old stone cottage. Throughout Derwent windows provided a clear, responsive and professional service, they managed our expectations and the team doing the installation were top notch. Time will be the real test of product quality but from the experience to date I have high hopes and no problems commending Derwent Windows for their delivery.

The sash windows of our Edwardian semi needed replacing. Our next-door neighbours had theirs replaced some years ago, by Derwent Windows, and have been very pleased with them. We thought they looked very good quality, as well as visually being almost indistinguishable from our originals. From the first contact with Derwent Windows through measuring, quotation, showroom visit to installation, the whole process has been excellent. All the staff have been friendly, helpful, knowledgeable and skilful. The quality of the windows and workmanship couldn't be bettered. We have already recommended this company to friends and neighbours, including those who have stopped to admire our windows and ask who did them!

We first used Derwent nearly 3 years ago to replace the door and windows at the front and then just recently to replace the rear windows. Both times they have been spot on and I would definitely recommend them without hesitation. As others have said, they came in slightly more expensive than other firms but their attention to detail on the fitting and finishing touches is outstanding. The first time, we had two windows knocked into one and they plastered, trimmed stonework etc and now you wouldn't know there was once two windows there. Second time they had a high window to replace on a stairwell but handled the challenge with ease. They are very friendly and super tidy, minimal touching up of paintwork needed. Thank you.

We have used this company before so we know how reliable and helpful they are. Obviously the schedule was interrupted because of the lockdown situation but we were kept informed about when the business could resume and we were given a new date as soon as possible. We were not disappointed, the work was done to a very high standard. Timekeeping was excellent and not a moment of the day was wasted. The room and outside area were left tidy and clean. I would have no hesitation using the company again.

The guys did a brilliant job... such careful work and attention to detail. They could not have been better. Felt the difference in the heat in the lounge immediately and the windows look great. Thank you so much for a very efficient, excellent job.

We had a new door and window fitted to a porch. The window and door were real quality products, a noticeable improvement over cheaper alternatives (you get what you pay for). Although the original installation date was missed (due to a problem at the manufacturers end), Derwent Windows pushed to get the door fitted before Christmas, which we were very pleased with. Thank you once again!

We are really pleased with our new replacement windows. The quality of the work is outstanding. Derwent fitters were friendly and helpful and worked very cleanly with no mess at all. The Windows have made a noticeable difference to warmth in the house. Love the look from the inside and outside. It wasn't the cheapest quote we had but certainly worth paying a little bit more for flush Windows. Wouldn't hesitate to use Derwent Windows again or recommend to friends.

We have just used Derwent Windows again to install more windows at our house, having been very happy with the first installation earlier this year. Once again the fitters were excellent, the windows themselves are superb and we would not hesitate to recommend them to anyine considerign quality window replacement.

High quality materials and finish. Very professional, knowledgeable and efficient. Work completed in the time specified. Fitters very pleasant and well-organised. House left clean and tidy every day. Admin staff very organised and helpful. End product entirely satisfactory.

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.
