Window Repair Run 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.
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.
Sash Window Repairs
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.
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
Resin Repairs for Rotten Wood
Resin restoration is often a far better option than complete replacement. Using specialist repair methods, damaged timber can be repaired, strengthened, and restored while keeping the original character of the window intact.
This approach helps maintain period features while reducing unnecessary replacement costs.
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.
