Timber Window Restoration & Repair Services

At SashWise, we believe original timber windows are worth preserving wherever possible. Ageing, draughty or difficult-to-use windows don't always need replacing. With the right care and expertise, many can be repaired, restored and improved while retaining the character and craftsmanship that make them an important part of your home.

Our specialist timber window services cover everything from full sash window restoration to servicing and draught proofing, rot repair, security improvements and timber window finishes. We assess the condition of your existing windows and recommend the level of work they genuinely need, whether that's a straightforward service or a more comprehensive restoration.

Working extensively with period and heritage properties across South West London and surrounding areas, we take a sympathetic approach to original timber joinery. Our aim is to retain as much of the existing window as practical while improving warmth, reducing draughts, restoring smooth operation and helping protect the timber for years to come.

Every window and property is different, so you don't need to know which service you require before getting in touch. Explore our timber window services below or speak to the SashWise team and we'll help you find the most appropriate solution for your home.
