Enhance Home Security

A renovated casement window is a secure one. We ensure every window closes tightly and locks properly, giving you complete peace of mind.

Our Casement Window Renovation Approach

Comprehensive Timber Repairs

Our renovation process begins with the timber itself. We are experts in 'timber surgery', meticulously cutting out all rot from frames and sills and letting in new, seasoned hardwood that will last for years.

Hardware & Functionality

A window is useless if it doesn't operate correctly. We focus on the mechanics, repairing or replacing seized hinges, broken handles, and worn window stays to ensure perfect, smooth functionality.

Weatherproofing & Performance

To improve your home's comfort, we can install discreet and highly effective draught-proofing systems designed specifically for casement windows, creating a weather-tight seal when closed.

Common Casement Window Problems We Fix

If you own a property with traditional timber casements, you’re likely familiar with some of these issues. We have the solution for timber decay in bottom rails, sills, and corner joints; swollen frames that stick or refuse to close; damaged or seized hinges, handles, and stays; peeling paint that offers poor weather protection; and noticeable draughts and water ingress around the edges.

 Trustindex verifies that the original source of the review is Google. We are absolutely thrilled with the work Avon Sash Repairs just finished in our daughter’s bedroom. They did an amazing job restoring the windows and installing heritage double glazing. A huge shoutout to Danny, who was fantastic to deal with from start to finish. He was completely honest, not pushy at all, and it’s obvious he takes real pride in his work and wants to put his name against a job well done. The quality is incredible and we honestly can't stop looking at the windows - my photo doesn't do it justice. We are really pleased with the result and can't wait to get them back to do the rest of the house. Thank you, Danny.

Danny quoted and communicated well; arrived when expected; ensured carpet and furnishings protected; and he and James did a great job on both tasks, weighted and re-corded, replaced and made good. Would definitely use them again for similar jobs and recommend them strongly.

The complete replacement of a rotted windowsill and installation of an exact hardwood replica with double glazing has transformed our third bedroom into a usable room again. The friendly professional service included protecting the whole area while the work was done, and a pride in the craftsmanship leaving fantastic results. We can’t recommend Avon Sash Repairs highly enough, thanks to Danny and the team for your five star work.

Really happy with our sash window reno by these guys - there was only 1 original sash remaining in our house and it had seen better days. Danny removed all the grimy flaky paint, took it back to bare wood, repainted, and left everything all neat and tidy. Now looks like a new window!
