Standard Sash Window Repair
Our comprehensive sash window repair service covers everything required to restore your windows to full working order. We carefully remove the sashes and beading, replace any missing putty, and strip away excess paint from the contact points to ensure smooth travel.
The sashes are rebalanced by checking and adjusting the weights as needed, and the pulley system is serviced and lubricated. New sash cords are installed, and we fit new parting beads and, if required, new stop beads.
For added security and functionality, we also offer the installation of new locks and restrictors as optional extras.
Draught Proofing
We install high-quality draught proofing systems that make your home warmer, quieter, and more energy efficient—without compromising the original appearance of your sash windows.
As part of this service, we renew and rebalance the sash cords, service the pulley system, and install our own custom-made draught-proof parting and stop beads.
This sealing system is designed to effectively block out cold air, wind, dust, and noise while preserving the historic charm of your windows.
Glass Upgrade
If you’d like to upgrade your original single glazed sash windows to improve safety, reduce outside noise, and enhance temperature control, we offer a number of smart, sympathetic solutions. At Heritage Sash Window Restoration, we provide a range of glass upgrade options designed to deliver modern performance while preserving the traditional look and feel of your windows.
In addition to glazing upgrades, we also offer a variety of other specialist services, including the repair of rattling windows, installation of locks, lifters, and latches, supply and fitting of spiral balances, and rotten timber repairs.
We can also provide replacement sashes, carry out putty work, repair broken glass, release painted-shut windows, and help reduce energy costs with tailored improvements. Whatever your sash window needs, we’re here to help restore comfort, function, and character to your home.
