Timber Sliding Sash Windows

Sash Windows In Huddersfield & Leeds

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 Sash Sliding Windows For Your Home

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.

Sash Window Renovations

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.
