Timber Window Repairs in Marylebone, London (W1)
Located in the heart of London’s W1 postcode, Marylebone is characterised by elegant period homes, boutique offices and refined commercial spaces. If your timber sash or casement windows are showing signs of wear — such as draughts, sticking sashes or rotting frames — you don’t need to replace them. With the right expertise, professional timber window repairs can restore aesthetic appeal, performance and longevity.
At Sash Restoration London, we’re specialists in timber window repairs in Marylebone and surrounding areas including Fitzrovia, Regent’s Park and Baker Street. We combine traditional joinery and heritage-sensitive methods with modern draught-proofing and finishing for homes and businesses alike.
Why Timber Window Restoration is the Smart Choice
-
Preserve unique character – Marylebone’s Georgian and Victorian properties often feature original timber sash windows which add charm and value.
-
Extending lifespan, not replacing – Targeted repairs (splicing, cord/pulley renewal, re-glazing) costs significantly less than full replacement and retains the original fabric.
-
Better insulation & comfort – Our specialist draught-proofing and resealing reduce rattles, leaks and heat loss without compromising the historic appearance.
-
Environmentally responsible – Repairing timber means less waste and lower embodied carbon than replacing the entire window.

Sash Window Overhaul & Repairs
We undertake complete sash window servicing: dismantling sashes, replacing cords and weights, cleaning and freeing stuck joints, replacing broken glass, re-balancing for smooth operation, and applying protective coatings.
