Overhaul & Draught Proofing
Overhauling & Draught proofing helps revive old windows so that they work as intended.
- Replace broken or damaged sash cords.
- Re-weight and balance your sash windows so that they run as intended.
- Draught seal your windows to stop leaks and improve efficiency.
In order to draught proof or draught seal, we will seal gaps that have formed around your window and frame. If your windows are not draught proofed this may lead to dust, dirt, cold air and noise entering your home. Draught proofing also helps with the smooth running of your sash windows. It also means savings on energy bills by keeping the hot air in, and the cold air out in the cold months.
