Expert Sash Window Repair Services Across London
Old sash windows are a beautiful feature of many London homes, but over time they can become difficult to open, noisy, draughty and inefficient. Instead of replacing your original windows, our specialist sash window repair service restores them to full working condition while retaining their period charm.
We repair and restore traditional timber sash windows for Victorian, Georgian and Edwardian properties throughout London. Our service also includes specialist repairs to timber and wooden window frames, rotten window sills, decayed timber, broken sash cords and damaged joints, helping restore both the appearance and structural integrity of your original windows. By repairing damaged sections rather than replacing the entire window wherever possible, we preserve the character of period properties while extending the lifespan of the existing timber and improving comfort, appearance and energy efficiency.
Common Sash Window Problems We Repair
Rotten Timber & Damaged Frames
We carefully remove decayed timber from sash windows, wooden window frames and window sills before carrying out specialist repairs that blend seamlessly with the original joinery. Wherever possible, we retain the existing timber to preserve the character and integrity of your period property.
Broken Sash Cords & Sticking Windows
If your sash windows are difficult to open or won’t stay in place, we replace worn cords, rebalance weights, and restore smooth operation.
Draughts, Noise & Heat Loss
Our discreet draught-proofing system helps reduce cold air, rattling, dust, and outside noise while improving insulation.
Loose Glass & Damaged Putty
We repair glazing, replace cracked putty, and secure loose panes to improve both appearance and performance.
Worn Locks & Poor Security
Upgrade your sash windows with modern locks and security fittings without changing their traditional style.

Repairing Every Part of Your Timber Sash Windows
Every sash window is made up of several timber components that work together to provide smooth operation, weather protection and structural strength. Over time, individual parts such as the frame, sills, bottom rails and glazing bars can deteriorate through age, moisture exposure or lack of maintenance.
Our repair service addresses these issues individually, allowing us to restore damaged timber without unnecessarily replacing the entire window. Whether your property has localised decay, damaged joints or worn timber sections, we use proven repair techniques to preserve as much of the original material as possible while restoring performance and appearance.
By focusing on repairing rather than replacing original timber wherever practical, homeowners can retain the character of their period property while extending the life of their existing sash windows.
Why Choose Sash Window Repair Instead of Replacement?
Replacing original sash windows is often unnecessary and expensive. In many cases, damaged sash windows, rotten timber frames, decayed window sills and other timber window components can be expertly repaired using proven techniques that preserve as much of the original material as possible. This approach restores smooth operation, improves thermal performance and helps maintain the traditional character of your home without the cost of full replacement.
By repairing rather than replacing original timber wherever practical, homeowners can extend the lifespan of their existing windows, improve energy efficiency and retain the craftsmanship that makes period properties so distinctive.
