What Our Clients have to say

Really happy with the finished product, the fitting team were great. The windows fitted perfectly and there was no mess at all.

I would just like to say how pleased we are with are windows from Derwent’s.   They were really helpful with choosing and advising us on their products and the build time required and kept us informed right up until the installation date.   The team that ran the installations are professional and really knew what they were doing, which helped when we had a couple of problems with historic movement.   The finish is excellent and the windows look fantastic. Now it’s up to me to make sure the decorating and furnishings match up to them!   Thank’s once again.   Mark Dudley

We had work done in two stages; the first was the front of the house. Derwent Sash Windows rebuilt the bay and installed windows and new front door. Although it was a major undertaking the work was carried out with professionalism and care. Each night all those on site were careful to clean up after themselves to minimise the disruption. The windows were better than we had hoped, and many people we didn’t know stopped by to admire them. We had the back of the house done 10 months later and are absolutely thrilled with the transformation as new stone sills and lintels have also also installed. The standard of craftsmanship is second to none, and with a completely different crew we found the same outstanding quality of professionalism, courtesy and pride in their work. The quality of the windows and doors are superb so we would recommend the company and their product to anyone seeking to replace or reinstall sash windows.

Once again Rob, Alistair and their excellent workmen have come up trumps! We cannot praise them enough.    This time we had twenty two sash windows replaced, the first time it was twenty. The installation was completed with the absolute minimum of fuss and disruption.    From our first contact to book the work to the last squirt of sealant everything was done to perfection. The lads on site were cheerful, polite and expert at what they did. By the end they felt like part of our family!   Many thanks to all concerned.    Never mind recommending this company to friends we would insist they use you!! Would recommend to a friend

All I can say is WOW! We live in an old cottage and our walls aren’t easy to work with but the quality of the installation is amazing. I highly recommend having the internal architrave if you have sash windows as it finishes them perfectly. From start to finish Rob, Alistar and the guys were first class and the workmen were courteous and professional and very clean. Great stuff. Would recommend to a friend

We have a period farmhouse and needed to replace the old single glazed wooden sash windows. Derwent installed Bygone collection UPVC sash windows for us and we are really, really impressed with the windows. The proportions ensure that they look wooden and are in keeping with the property. The compliments from visitors have already started and people are surprised to find they are UPVC. Andy and the team were super. Hard working and also tidy workers, something I have learnt is not common place with workmen! The quality of the finish is very impressive, thank you!

We had our upstairs windows replaced by Derwent earlier this year and everything about the process has been first class. The products are excellent, the workmanship of a very high standard and we absolutely delighted with the results.    People have been stopping us in the street as we leave the house to ask us about our lovely new windows.    From our initial enquiry through to the end of the installation we couldn’t fault anything and look forward to returning for the rest of the windows as soon as possible.

We had 14 new windows, opted for the UPC sash and installed they look superb. The postman has just commented how good a job has been done and was genuinely surprised when I told him they were not wood.    We are also having two replacement doors, one is fitted, another lovely job and the front door is ongoing, we are waiting for the encapsulated glass panels to be fitted.   Derwent are not the cheapest but they do a quality job using a quality product. The three gentlemen (Mark, Mike and Ian) were pleasant and extremely efficient. Little or no mess at all and apart from the architrave requiring painting we have no redecoration work to do at all.   We decided to go ahead based upon a recommendation from friends after we had viewed the windows they had had done. We visited the showroom and the whole process was made very easy by the helpful knowledgeable team, Jan doing the paper work, Alistair doing the ‘non-pressure’ selling and Rob doing the measuring. &nbsp

Thank you for the excellent work.

Dear Alister, Thank you and your colleague Mark for a lovely installation. My wife and I are very pleased and it looks the business. Kind Regards
