Window Draught Proofing
Window drought proofing prevents mould growth in your house and helps avoiding problems of increased humidity. The other benefit is that it ensures your windows flow freely as the timber moves against soft brush rather than timber. Our services will leave your house warm and quiet without affecting the character of your property. We always ensure minimal disruption to the decorative appearance of the window.

Windows that are poorly fitted not only appear unkept but also allow the cold in, start rattle and cause heat loss. It is one of these issues that our comprehensive draught-proofing service at Restore My Window resolves. Draught Proofing helps to eliminate cold air coming through the holes in your window and helps to keep the warmth inside. It also reduces the external noise and, what’s the most important, reduces your energy bills significantly.

Frequently Asked Questions
Draught proofing is the process of sealing the gaps and openings around your window frames and sashes to stop cold air entering and warm air escaping. On timber sash windows in particular, which are common across London’s Victorian and Edwardian housing, gaps naturally develop over time as the wood shrinks and the frames wear. At Restore My Window, our professional wooden draught proofing service installs specialist brush pile seals and compression strips into the sash channels, reducing draughts by up to 95% while preserving the smooth sliding action of your windows and the original character of your property.
There are DIY draught proofing options available, self-adhesive foam strips and brush seals from hardware stores can reduce cold air temporarily, but for timber sash windows, a professional service delivers far better and longer-lasting results. A specialist will strip the sashes from the frame, fit precision-cut brush pile seals into routed channels, and rehang the sashes so they run smoothly against the seals. This is a more involved process than draft proofing a standard casement window, but it’s the only method that genuinely eliminates draughts without compromising the window’s function. Our draught proofing London service includes an assessment of your frames and a clear, upfront cost before any work begins.
The cost of professional window draught proofing in London depends on the number of sashes, the condition of the frames, and whether any repairs are needed before the seals can be fitted. As a guide, sash window draught proofing is typically priced per window and is considerably more affordable than full replacement , making it one of the most cost-effective energy efficiency upgrades available for period London properties.
