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 is common in Georgian, Victorian and Edwardian houses, gaps naturally develop over time as the wood shrinks and the frames wear. At RestoreMyWindows.ie, our professional wooden draught proofing service installs specialist brush pile seals and compression strips into the sash channels, reducing draughts by up to 93%+ 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 remove 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 service includes an assessment of your frames and a clear, upfront cost before any work begins.

The cost of professional window draught proofing 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 heritage properties.

Absolutely, professionally draught proofed sash windows can reduce heat loss through your windows significantly, lower your energy bills, cut external street noise, and eliminate the rattling that poorly fitted sashes cause over time. For homeowners with original timber sash windows, it is almost always the recommended first step before considering double glazing or full replacement. Our draught proofing service also prevents moisture and humidity build-up inside the frame, which is a leading cause of rot in wooden windows. The improvement to day-to-day comfort is immediate, and the work causes minimal disruption to your home, most installations are completed within a single visit.
