Few windows are as stunning as classic sash windows, and Thornton Windows have a wealth of experience in both fitting newly manufactured sash windows, and restoring existing sashes to their former glory.
If you have a period property with tired or damaged windows and you want to replace these original frames with authentic new sashes, or your windows require some professional attention to bring them back to their best, we are here to help.
New sliding sash windows from Thornton Windows will give your property real kerb appeal; adding value to your home and allowing you to enjoy the benefits of modern, energy-efficient windows alongside the classic style that only a sash window can offer. Why not get in touch for more details?
If your existing windows are beyond repair, we can design and produce new sashes which replicate the authentic style of the originals, but which offer the energy-saving benefits of modern, efficient windows.
Sometimes older sashes cannot be saved with restoration, and in this case, you can trust our team to advise you honestly if a replacement is a more cost-effective option.
Using the finest materials and timber, we can produce high quality sash windows which our customers love. Contact us today to learn more.
We also undertake renovation of old sliding windows. Your property’s sash windows might be one of its best features, but time and wear and tear can soon leave your windows looking less than perfect.
Thornton Windows can restore even the oldest of sash frames and will complete a sympathetic renovation which maintains the authenticity of your windows.
You can trust our talented team to leave you with windows which look as good as new; complementing your property and making it stand out for all of the right reasons.
We offer a large range of colour options for your chosen window to suit the style of your home and your own taste. All our timber products are made bespoke.
Contact us today to view the range of colour options for your windows.
Because we’re confident in the quality of our products, as standard they come complete with a 10 year guarantee.
All our Thorntons Timber products are made with Accoya Wood.

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!
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.
