Timber window renovation and restoration

Window Restoration
Even the most neglected timber windows can be restored and their performance enhanced. It takes skilled craftsmanship and specialist knowledge to make this happen.
Restoring existing timber doors is often more cost-effective and favoured by planning authorities who value the preservation of historical features. This approach also offers a more sustainable option that minimises waste by retaining as much of the original door as possible.
Simplify window maintenance with SRS
Designed with a unique brake mechanism, the SRS secures sash cords in place and allows for easy removal of both upper and lower sashes. This provides you with unrestricted access for hassle-free cleaning, painting, and maintenance of your existing windows.
