Mr Bowhay – Eastwood

This is the second time we have used Derwent sash and both times they have been fantastic. The quality of their work is first class and the products they use are excellent. The staff are always friendly and easy to deal with making sure that everything they do is exactly how we want it. They also are really clean and efficient in their work such that when they leave, everything is exactly as it was before they arrived… Except with beautiful windows now in place. Can’t recommend them enough!

Linda Mckie – Barnsley

The ’Symphony Bygone Collection Sliding Sash Windows’, including ’Full Timber Jointing with Super Slim Meeting Rail’ surpasses all our expectations of a UPVC product: the appearance is that of a timber window, which compliments our stone fronted property perfectly/beautifully – look sensational!!. The bespoke hardwood door, made by Rob, painted in Manor House Gray (Farrow & Ball) and Off White, is stunning: we left the final design with him and are absolutely delighted with the finished result – the effect is GORGEOUS!! (If you need a custom made door then Rob is your man.) Both the door and windows were installed with internal period architraves and stub cill in natural timber finish, which was the ’deciding factor’ when selecting Derwent Sash Windows. The full installation was impressive: a highly professional/skilled team were thorough from beginning to end (they covered up absolutely everything before starting work); their attention to detail was impeccable during every part of the job: installation of all the products was completed to a high standard. If you want the appearance of a timber window without the maintenance then look no further: my husband and I can highly recommend Derwent Sash Windows.

Mrs Neil – Long Eaton

I have great pleasure in recommending Derwent Sash Windows. I had lots of companies come and quote and Derwent were the only people that I was happy to do business with. There was no hard sell. They didn’t ask if my husband would be at home. There was no pressure and no rush.    They are very flexible. I have done a few windows at a time.    They were also the only company that was able to source and fit some stonework.  The fitters are very clean and polite and work really hard. It was a pleasure to have them in my house.    I will miss them all once my last two windows are done.

Mrs Greyson – Sheffield

I would highly recommend Derwent Windows.  I have been in a dilapidated Victorian terrace for almost a year and had numerous quotes given. I knew that new windows would transform my home but particularly wanted one company to do all the work but also provide original looking 0 maintenance windows that itself was a challenge with previous quotes for bricking up doors and adding an extra window became very complicated with subcontracting involved. That for me was the deciding factor in choosing Derwent they did everything not to mention the supply of the most stunning Upvc sliding sash windows and a French door from a window. The brickwork and finishing by Mick is superb and he went above a beyond my expectations. Thanks to the whole team at Derwent. Kind regards Jane Greyson

Mr McMaster – Ripley

Rob and the team at Derwent Sash were a pleasure to deal with, the professionalism, quality of work and products are second to none.    We are extremely pleased with the service and the windows we had installed, it’s truly transformed the appearance of our property and added that extra quality and kerb appeal that we couldn’t get from any other local window supplier.   Thank you Derwent Sash!

Mrs Ray – Long Eaton

My new windows and front door are awesome. I gained three quotes and they were the most expensive but – I’ve worked hard and they are stunning and I’m worth it!

Mrs A Wilson, Osborne Grove, Nottingham NG5 2HF

We are so happy with the windows! I have spent a very happy few minutes shutting and locking them for the night just now, and it gave such a warm sense of peace and security. Our builder Ivan is really impressed, and we’ve already been getting people asking him and us where they are from! And please thank your two guys, Mick and Andy,. They were really professional and very friendly and nice to have around

Mrs Williams – Barnsley

Quality product, quality service and a pleasure to deal with. We couldn’t be happier!  After being recommended them by a friend I will certainly be recommending further to all I know. A professional team with exceptional craftsmanship.
