Timber Window Repairs in Highgate, London (N6)

​

From handsome villas in Highgate Village to period terraces bordering Hampstead Heath and Dartmouth Park, original timber windows define the area’s character. If your sashes stick, frames show signs of rot, or draughts whistle through, you don’t need uPVC replacements. With specialist care, timber window repairs restore performance, comfort and curb appeal—while keeping your property authentic.

​

At Sash Restoration London, we deliver expert timber window repairs across Highgate (N6) and nearby Hampstead, Archway and Muswell Hill, using conservation-friendly joinery, discreet draught-proofing and long-life finishes for both residential and commercial buildings.

​

Why Choose Restoration Over Replacement?

​

• Preserve heritage value – Retain original joinery, horn details and glazing bars typical of Georgian, Victorian and Edwardian windows.

• Lower lifetime cost – Targeted repairs and maintenance often outlast low-grade replacements.

• Warmer, quieter rooms – Professional draught-proofing and sash rebalancing cut air leakage, rattles and street noise.

• Sustainable choice – Repairing timber reduces waste and embodied carbon compared with full replacement.

 

Bottom line: quality repairs protect what makes Highgate homes special—while improving day-to-day comfort.

 

Our Timber Window Repair Services in Highgate

​

Sash Window Overhauls

We dismantle and service your sashes, renew cords and pulleys, free paint-bound joints, replace cracked panes, and rebalance weights for smooth, fingertip operation.

 

Timber Splice & Frame Repairs

Where decay is present, we excise rotten sections and install hardwood splices with traditional joinery (and resin consolidation where appropriate) to restore structural integrity and profiles.

 

Heritage-Sensitive Draught-Proofing

Subtle perimeter brush seals and parting beads reduce air leakage and window rattle while remaining virtually invisible—ideal for conservation areas and period façades.

 

Slimline / Acoustic Glazing (Subject to Permissions)

For suitable properties, we can specify slimline heritage glazing or acoustic laminates to enhance thermal and sound performance while maintaining original sightlines.

 

Preparation, Painting & Finishing

Meticulous prep, resin filling, primer build and premium microporous topcoats protect against weathering and UV, extending maintenance cycles.

How long does a repair take?
Minor cord renewals: a few hours per window. Full restoration with splicing, reglazing and repainting: 1–2 days per window, depending on condition and drying times.
