Sash windows are perfect for updating an older property with ease; by removing older, wooden-framed single glazed windows and replacing them with our modern, A-rated double glazed sash windows you get the best of both worlds – brand new, secure and energy efficient windows with all of your property’s original charm.
The vertical sliding sash window is the fastest-growing alternative choice of uPVC window style, giving your customers all the benefits of highly advanced materials and mechanisms combined with a timeless classic window style.
We offer a large range of colour options for your chosen window to suit the style of your home and your own taste.

Because we’re confident in the quality of our products, as standard they come complete with a 10 year guarantee.
Initiated by a very prompt visit to give a quote which was competitive with other local firms, we were persuaded by the company’s ability to tailor the product to our needs. Manufacture was within the timeframe promised and fitting, thanks to a cancellation, ahead of schedule.
Very pleased with our new Bay Sash Windows and frosted bathroom sash.
Thank you Thorntons; we will be back in touch
Had a new front door fitted by Thorntons 2 yrs ago and because they were faultless in every way, asked them to fit a new back door just recently. Everything, yet again, was faultless (initial quote process, installation and general customer service). Couldn’t recommend them highly enough.
These chaps are thoroughly professional. we had PVC windows and wooden doors fitted in December 2019.
Quick, minimal disruption, quality job and cleaned up after. special attention to final finish means these guys go the extra mile to ensure a truly fantastic job all round.
Thanks for a brilliant job.
I regularly use Thorntons Home Improvements to supply bespoke windows and doors alongside my joinery business. Always top quality work and the lads can’t do enough to help me out. Highly recommend.
Had a Solid Roof put onto my existing Conservatory, had a pleasant experience from start to finish, Lindsay and has staff were very helpful and experienced, very happy with the end product, well done team Thorntons!
