Derwent Sash Windows Ltd t/a Derwent Windows and Doors

We have had new windows and a new rear door from Derwent. We've been very pleased with the service from start to finish. The staff have been highly professional and easy to work with. Would highly recommend and wouldn't hesitate to use them again.

We had seven hardwood sash windows and a set of orangery doors replaced by Derwent Windows this month and have been delighted with the finished product and the quality of service throughout the entire process. The fitters were extremely professional and hard working, and despite having to contend with heavy rain throughout the installation, our house and driveway were left spotless after each day's work. I would not hesitate to recommend this company to anyone looking for quality replacement windows, and we have already requested a further survey for additional work at our house.

The work was carried out to time and high standard. The workmen were polite and kept everywhere as clean as possible during the work and cleaned up when they finished. We were delighted with the high quality of the door and frame and the way it was finished and fitted. We were kept informed throughout from ordering to delivery and would highly recommend this company.

After Derwent replaced our front windows about 10 years ago - a job we were very pleased with - we decided to use them again to replace our ageing rear windows with wood-effect uPVC (in our opinion, it looks just as good as painted wood, and there is a lot less maintenance). We made 2 or 3 visits to the showroom, where there are comprehensive displays of all the ranges they sell. They deal only in high-quality frames, so this is not the firm to use if you are looking for cheap double glazing. Service throughout was helpful and courteous, with good and frequent communication by e-mail and phone. One window required stained glass, and they directed us to a local expert company to choose the glass colours. The installers work long days and just get on carefully and expertly with the job, including moving and protecting furniture etc., and cleaning up at the end of each day. We are very pleased with the appearance and quality of the finished installation. A courtesy call from Andy today to ensure we were happy was a nice touch.

Derwent Sash Windows recently installed new sash windows to the front bedrooms of our Victorian terraced house. Their team, from initial consultation to completion of work, was excellent throughout. The windows are superb and met the local council's planning requirements for the conservation area. We would definitely recommend them.

I had 5 replacement sash windows and front and back door. I am absolutely delighted with them. They look amazing. I had a few quotes in and Derwent stood out by a mile from the start. Definitely recommend a visit to the showroom. The fitters did an excellent job and clearly take a pride in their work. Would rate 10/10

We had our old UPVC windows replaced with timber casement windows from Derwent. Their customer service from visiting the showroom to the finished windows is first class, everything from a deposit protection policy to polite, skilful & tidy fitters. The timber windows look great and make such a difference. We would highly recommend Derwent to anybody looking for new windows, it's exactly how a company should be run but so few are.

Derwent fitted 11 sash windows into our Victorian house. We had seen other houses in our area fitted with their windows which have stood the test of time; Andy clearly explained the differences between products Derwent offered and was able to guide our decision-making. The whole process from start to finish has been top quality, as are the windows. Communication has been clear and courteous, all staff have been trustworthy and friendly, and the windows enhance our property. The budget and schedule were adhered to. I highly recommend Derwent Windows.

We cannot recommend Derwent highly enough. Every aspect of the work carried out renovating a number of large stained glass windows in our late Victorian house was excellent: quality of the product, craftsmanship, efficiency and cleanliness of the installation, and customer service throughout the project. Advice and guidance, and communication from the Derwent team were also outstanding from initial discussions to completion.

We had a front door fitted in January and have been very pleased with the standard of care throughout the process. The quality of the goods is excellent as is the skill of the fitter, Dougie, who made a super job. We are delighted and will use the company in the future.

Brilliant company from start to finish cannot commend them enough. The windows have totally transformed out property. The workmanship was brilliant and the fitters worked tidy and efficiently and are a credit to the company. Safe to say we will be using them for the other bits we plan to have done.

Derwent Windows fitted a new front door for us. They were helpful and kind throughout the whole process. From the initial estimate to design details and the final fit, they have been great. We are very pleased with our new front door!

We had a replacement hardwood front door and surrounding frame and stained glass encapsulation. The original stained glass windows were removed about a month prior to fitting. Expertly removed and our home securely boarded up. We are delighted with the finished product. The original stained glass and leaded window has been carefully cleaned, repaired and encapsulated and looks amazing. The new front door is also of a really high quality and finish. The fitters removed and fitted the new frame, window and door in a day, with minimal fuss. We were consulted throughout the fitting on minor details that needed a decision . We contacted Derwent Windows the following day about a small issue we had found and it was promptly dealt with. Highly recommended for quality of product.

We recently used Derwent Sash windows to install Origin bi fold doors and windows. Their professionalism and customer care are excellent. All the staff that we dealt with have been very helpful and efficient. The doors and windows look outstanding and have completely exceeded our expectations. Particular thanks must go to Alister, Andy and Jan who are a huge asset to the company and have stayed in touch constantly throughout the ordering and installation process. Also the professionalism of the installation team and cleanliness in their work was equally as impressive. We also had between the glass blinds fitted by Derwent Sash windows and these really show the quality of the doors and windows. We are extremely impressed with this company and wouldn't use anyone else.

Our new sash windows look just right in our 1900s town terraced house, matching the style and exceeding the quality of the original ones. The service from Derwent Windows was expert, appropriate and on time. Attention to detail was given at every stage of the process, so that the resulting windows look fantastic. Thank you.

We had all the windows and doors replaced. We chose Derwent windows because they supplied Evolution windows which I considered to be the best on the market. The price was the price and non-negotiable but we considered this a positive after dealings with other National firms who's starting prices were frighteningly high followed by pressurised negotiations! Derwent were very helpful with choosing and detailing, but some confusion arose because we talked to four people, this was resolved when we asked for one focal contact (hence the 4 star rating). The installation team were fantastic, polite, helpful, covered everything with plastic sheeting and no problem was too small. All snags were resolved to our complete satisfaction.

Very high standard of workmanship. Beautifully made and fitted door and windows. They even opened up the old fanlight over the door, which had been bricked up years ago. The plastering afterwards was of a very high standard too. Courteous and prompt service. I would recommend highly to anyone in this area.

Our new front door has been long anticipated and we are thoroughly delighted. The Derwent windows showroom is worth visiting to visualise the quality and range of products available. The staff are exceptionally helpful and the whole team is absolutely delightful. This is a full package with complete attention to detail. We had 3 site visits to plan, design and measure the door, we had books and samples which allowed the whole family to contribute their opinions. The office staff were supportive and available throughout the process, ready to answer queries via telephone and email. On the day of fitting the men were prompt and did a beautiful job. We could not be more pleased. Perhaps it's a sign of my age that I have taken a photo of my new front door to work with me? I recommend this company and we will certainly use them again.

Changed all of the windows in our house and have to say this was the one of the best customer experiences I've ever had. The owners and workers are courteous and considerate and completely customer focussed. They bend over backwards to make sure you are happy. They made no mess and finished very quickly. I have full confidence any aftercare we would need if any problems should arise. This is how every company should operate. So glad I went with these guys. I wholeheartedly recommend them.

Derwent Windows have again provided great service from purchasing to fitting. Helpful, friendly, professional and tidy. I would recommend them to anyone.

Everything went very smoothly from the search for what we wanted, deciding upon a design, ordering and paying for two sash windows. They were installed with the minimum of disruption, on the day appointed and within the timescale suggested. The installers were all very helpful, covered all surfaces on the stairs and in the rooms where the windows were to go, worked tidily , left things clean and were even prepared for the rain that fell. good follow up and attention throughout the whole process.

We recently had 2 new windows fitted by Derwent, previously they have fitted a new bay window and a door. Bespoke quality products fitted with care and attention to detail.

An extremely professional and helpful company with every member of the team from the start to the end of the process fantastic. They listened to my requests and have changed two french doors with side half windows into to two french doors with full length side panels which has totally transformed our view of the garden. High recommend using oak, as even though it was far more expensive the gain really comes out in the finish of the wood. Will definitely only use this company for windows in the future.

We are very pleased with our new windows and doors. Derwent Windows have been extremely helpful and professional throughout the entire process. We will be engaging them again next year to have our extension windows and doors installed. We would happily recommend Derwent Windows to anyone, and would be only too pleased to provide a reference if it is required.

We recently had new wooden doors and windows fitted. Due to the fact that they were bespoke, we had to wait 12 weeks for them , but they were well worth the wait. Derwent Sash Windows Ltd did a beautiful job: neat, fast and professional. I was particularly impressed with the care taken to protect my furniture and belongings during the work, and they did a great job of tidying up afterwards. Communication was prompt, professional and warm, and they even took the trouble to returning a beloved keyring I had inadvertently left in my old door.
