Derwent Sash Windows Ltd t/a Derwent Windows and Doors

Derwent Windows provided the best customer service we have ever experienced. They were extremely helpful, very professional and the standard of work from the fitters was outstanding. Whilst the windows are not the cheapest, the quality is high and we would definitely choose them again.

Derwent Windows gave an excellent service from the quotation assessment to the detailed site survey and then to the installation. I thought the nature of the site survey was particularly useful; we discussed the nuances of the installation and they were able to answer all of my queries in a detailed yet easy-to-understand manner. Therefore, I was very confident in the installation ahead, which mostly, I would not be at home to witness. The quality of the work carried out was very good. The sash windows provided are of excellent quality and the wooden architrave and facias (made on-site, at my home) that surround the internal of each window fit perfectly between the window and the wall. The slightly high price of the installation was largely driven by the need for quality sash windows that are in keeping with the age of my house and the conservation area in which I live. Informal quotes from other companies using the same type of manufactured sash windows gave a similar ball-park price. I was very pleased with the service provided by Derwent Windows and would recommend them to future potential customers.

We had a solid wood sash window replaced by Derwent Windows. The quality of the product is top rate & the fitters did an excellent job, very thorough, polite & exceptionally well cleaned during & at the end of the job. The time from order placed to fitting was very considerable , but that is the same very where I imagine. They are not the cheapest windows on the market, but I would rather pay a premium for the product quality & craftmanship. I would definitely use again & would recommend Derwent Windows

Derwent Windows were able to provide arched timber windows entirely in keeping with our early 19th Century Old Toll House. The transformation to our house has been amazing. So many neighbours have commented positively on the appearance of these windows including some older people who remember what this house used to look like. Comments like ' your new windows look stunning' have frequently been made. We are delighted with the difference these windows have made to our home - not only in appearance but also in better heat and sound insulation. The team did an excellent job and were a pleasure to work with. Follow-up after sales was also very good. There is no doubt that this project was expensive but we were prepared to pay for quality and see it as an investment in our property. But mainly we see it as a great improvement to our home on the edge of the beautiful Peak District.

So glad I made the journey to Ripley to see Derwent Windows. Had planned to used an installer locally but none of them return my call after quote stage. Derwent were brilliant from the moment I rang them. Arrange a time to visit their showroom and even what bus to catch to their showroom. A survey was done within a week of the visit. Their knowledge and customer care was so good, I put an order in straight away. The actually installation went smoothly. The fitter was great - explain everything that was going to happen and was so meticulous in the installation and tidied up afterwards. I am thrilled with my door. Wish I chosen them from the beginning. Thank you to all the team for their help!!!

Project went to plan. We chose our preferred door. Surveyor came out to measure and following his visit felt reassured that we’d made the right choice. Proof of the pudding though is installation. The installation team were first class and we are thrilled with the door. All round first class service and product.

We have used Derwent windows 3 times now and would highly recommend. From start to finish everyone is great to deal with and the standard of the work is second to none.

We can't rate Derwent Windows highly enough. They conducted the initial site visit and provided wisdom and expertise about what our house may have looked like originally to help choose the right products. He was very patient while we looked at different options and we felt able to trust him. They then coordinated surveys and commissioned builders for us to do lintels and stonework. All calls and appointments happened when they were agreed, no issues and any sticking points were talked through clearly. Everyone in the office organised the quotations and final details without any fuss or mistakes. Then the builders and fitters did an absolutely superb job - we have had multiple comments from neighbours and passers by about what a great improvement and how sympathetic the new windows are. They are quality products that look set to last. We are very glad we trusted Derwent with this work.

Rob and the team from Derwent Windows have designed and built us a superb orangery. The team have been consistently hard-working, punctual, and professional throughout the process. Rob has site managed the project throughout. He has always kept us informed at each stage of construction, providing daily updates. The finished build is outstanding in quality and beyond our expectations. This is the third time we have used the company and would not hesitate to use them again in the future.

We were looking for traditional sash windows to fit into a renovation of a Georgian property. Derwent really impressed when we saw the product in the showroom. Cost was not excessive for the type of product. Fitting went extremely well with the professional installers doing a clean, quick and beautiful job. I will use them again for the next part of the renovation.

Thanks for all your help and advice over the past months, the whole service Derwent provided from the day we came over to the showroom to view in April, Andrew expertly surveying the work, to admin answering our many questions, until the fitters completed the work has been absolutely first class. It has been great to work with a company that take so much effort and pride in delivering such good customer service not only in ensuring the quality of the finished product, but also in the care, detail, politeness, personal service and interest shown by all the staff involved throughout the project. A particular thanks to Dan, Mark, Ben and Calum who worked tirelessly in difficult conditions to fit the windows. The detail, care and effort they put in to ensure the finished article was perfect, was superb. They really were all excellent throughout and nothing was too much trouble. Our old windows had been in for probably 150 years, so you can imagine the amount old dust and dirt created from behind the frames once they were removed. The fitters worked diligently to clean up after themselves and return the rooms to pristine condition each night, leaving us with very little work to do, for which we were understandably very grateful. The windows both upstairs and downstairs look great, many thanks. We will definitely be telling all our friends about Derwent Windows and look forward to working with you again in the near future

From measuring to fitting, nothing was left to chance. Windows arrived on time and were speedily and professionally fitted. Everything was “made good” afterwards with no fuss. In fact, I was so impressed both with the quality of product and fitting, I ordered another set to match. As I say, a first class company with first class staff.

Many thanks, our new sash window with the 120 year old original stained glass encapsulated within it looks great. And much more robust than the original had become!

Derwent supplied and fitted a new front door and surround for our 1920’s house. Very pleased with the appearance and quality of the product, the quality of the work done and the work ethic/conduct of the team who did the work.

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.
