Traditional Timber Window Specialists
Original timber sash windows were designed to last for generations. Unfortunately, years of neglect, poor maintenance or inappropriate repairs can leave them difficult to use and susceptible to weather damage.
Our skilled craftsmen understand traditional window construction and use time-served restoration techniques to preserve as much original timber as possible.
Rather than replacing historic windows with modern alternatives, we restore their appearance and functionality while improving energy efficiency and reducing draughts.
Improve Energy Efficiency
Older sash windows often suffer from air leaks that make homes colder during winter.
Our restoration process can significantly improve thermal performance through:
- Professional draught-proofing
- Accurate sash alignment
- New weather seals
- Timber repairs
- Improved closing mechanisms
These improvements help reduce heat loss, lower energy bills and create a more comfortable living environment without changing the appearance of your period windows.
Sash Window Repairs
Many customers assume damaged sash windows require complete replacement.
In reality, most common issues can be repaired, including:
- Broken sash cords
- Rotten timber
- Loose joints
- Cracked glazing
- Damaged putty
- Stiff windows
- Rattling sashes
- Water damage
- Broken locks
- Faulty pulleys
- Misaligned frames
Our repair-first approach helps retain original features while extending the lifespan of your windows.
Draught Proofing Sash Windows
One of the most popular improvements we carry out is professional draught-proofing.
This discreet upgrade reduces:
- Cold draughts
- Heat loss
- External noise
- Dust ingress
- Window rattling
Unlike replacement windows, draught-proofing maintains the traditional appearance while delivering noticeable comfort improvements.
