A warm, comfortable home depends on windows that are properly sealed and functioning as they should. When draughts start creeping in, it’s more than a minor irritation – it affects energy efficiency, increases heating bills and reduces overall comfort. At Fix-It Windows, we often find that draughty windows are caused by a handful of common issues, many of which can be fixed quickly and affordably. Here’s why your windows may be letting in cold air, and what you can do about it.
Worn or Damaged Window Seals-
The most frequent cause of draughts is deteriorated seals. Over time, weather exposure causes rubber seals to shrink, become brittle or peel away from the frame. Once the airtight barrier is broken, cold air easily enters your home.
If you notice gaps around the edges of your windows, condensation between panes, or increased noise from outside, your seals may be failing. Professional window seal replacement is often the quickest and most effective solution, restoring proper insulation and helping reduce heat loss immediately.
Loose or Faulty Hinges and Mechanisms
uPVC windows rely on hinges, friction stays and locking mechanisms to close tightly against the frame. When any of these components become loose or worn, the sash won’t sit correctly, creating small but significant gaps.
This is one of the most common call-outs we receive for uPVC window repairs. A simple hinge realignment or replacement is often enough to eliminate the draught completely, without the need for new windows.
Misted or Failed Double Glazing Units
If you notice condensation trapped between the panes of your double-glazed windows, the unit has failed. This means the insulating gas has escaped and moisture has entered – drastically reducing thermal performance.
In this situation, replacing the glass unit rather than the whole window is usually sufficient. Customers often contact us for misted double glazing because misted windows not only cause draughts, but also look unsightly and can affect the value of your home.
Frames That Have Warped Over Time
Weather, age and poor installation can cause uPVC frames to warp or shift slightly, preventing the window from closing snugly. Even a small distortion can create noticeable draughts.
Luckily, this can usually be corrected through expert adjustments. Our technicians frequently help homeowners fix double glazing simply by repositioning hardware, re-setting the sash or realigning the frame.
Don’t Ignore Draughts – Fix Them Early
Even minor draughts can have a big impact on your heating efficiency. According to UK energy studies, poorly sealed windows can account for a significant percentage of heat loss in a home. The good news is that almost all draught-related issues can be repaired quickly – and at a fraction of the cost of replacement windows.
