Draughty windows can be a major source of heat loss in the winter, causing energy bills to rise as heating systems work harder to maintain a comfortable temperature. However, a DIY expert has shared a simple method for identifying and fixing the problem without the need for professional help.
In a viral TikTok video, a woman named Emma demonstrated how to locate a draught using a feather. By holding the feather against different parts of the window, viewers can see exactly where air is entering when the feather moves. Once the source is identified, the fix may be as straightforward as adjusting the compression settings on the window's locking cams.
Emma explained that many modern PVC windows have adjustable compression settings, which can be tightened during winter as windows expand and contract with seasonal temperature changes. She advised checking the small notch on the cams: if it faces towards the frame, the cam is at its tightest, while a notch facing away indicates a looser setting. Using an Allen key, she turned the cam to the correct level of tightness to eliminate the draught.
If the window does not have manual compression adjustments, or if the problem persists, Emma suggested replacing the rubber seals around the edge of the window or using draught-excluding tape as a temporary solution. Commenters on her video were grateful for the advice, with one saying: "I was literally considering calling a worker out to fix our draughty windows. You've just saved me a fortune."
According to the Eco Experts, windows are a major cause of energy loss, and Historic England estimated in 2022 that as much as one-fifth of heating is lost due to draughts. Other DIY measures include fitting self-adhesive foam strips, placing a draught excluder at the bottom of the window, or hanging heavy curtains to keep cold air out.
