Sash Window Repair by Nick Smith from Stamford

NJS is a small, experienced team specialising in traditional sash window renovations, resin repairs for rotten wood, timber restoration, and bringing old windows back to life properly — not just patching them over.

Sash Window Repairs

We’ve worked on period homes, Victorian properties, townhouses, cottages, and listed buildings over the years, helping customers preserve original timber windows instead of replacing them unnecessarily.

Old sash windows naturally suffer from years of weather exposure, moisture, cracked paint, and timber decay. At NJS, we focus on repairing and restoring existing windows wherever possible.

Sash Window Services include:

• Rotten wood resin repairs
• Timber restoration
• Sash window renovations
• Window frame repairs
• Draught reduction
• Sill repairs
• Cord and pulley repairs
• Exterior timber restoration
• Traditional window refurbishment

Wood Window Restoration

Wood window restoration is often a far better alternative than complete replacement. In many cases, damaged timber can be carefully repaired, strengthened and restored using specialist repair methods, helping preserve the original character of traditional sash windows.

Rather than replacing an entire window set, we can often repair rotten sections, restore timber, carry out resin repairs and upgrade worn components while maintaining the period appearance of the property — often at a far lower cost than full replacement.

Traditional Craftsmanship

 

NJS has been in the trade a long time and continues to work with both previous customers and new clients looking for honest, reliable sash window restoration work.

We keep things simple — small team, hands-on work, and a focus on doing the job properly.
