Feeling a chill near your windows, even when they're closed? Draughty windows are one of the most common comfort complaints for homeowners, especially during the colder months. In this guide, we'll explore the most frequent causes of window draughts and help you understand whether you need a quick fix or a more permanent solution.
What Causes Draughty Windows?
There are several reasons why your windows might be letting in unwanted cold air. Identifying the cause is the first step towards finding the right solution.
Failed Seals and Gaskets
The rubber seals (gaskets) around your window's opening sash create an airtight barrier when the window is closed. Over time, these seals can shrink, harden, and crack, breaking this barrier and allowing cold air to seep in. This is one of the most common causes of draughts and is often repairable on newer windows.
Warped or Damaged Frames
Extreme temperature changes, age, and moisture exposure can cause window frames to warp or swell. This prevents the sash from closing properly against the frame, creating gaps. Timber frames are particularly susceptible to this, but older uPVC can also suffer over time.
Faulty Hardware
Hinges, handles, and locking mechanisms all play a role in pulling the sash tightly into the frame. If these components are worn, broken, or misaligned, the window may not close securely, leading to draughts.
Gaps Around the Frame
Sometimes, the issue isn't the window itself but the installation. Gaps can appear between the window frame and the surrounding wall if the original sealant has failed or if there's been any structural movement.
Old or Single Glazing
If your home still has original single-glazed windows, or very old double glazing, cold air can radiate through the glass itself. While this isn't technically a "draught," it creates a similar sensation of coldness near the window.
Can Draughty Windows Be Repaired?
The good news is that in many cases, draughty windows can be repaired without needing a full replacement. Here are some common fixes:
- Replacing Seals: Worn gaskets can often be replaced relatively easily on modern windows.
- Adjusting Hardware: A skilled technician can often realign hinges and adjust locking mechanisms to improve the seal.
- Re-sealing Frames: Applying new sealant around the window frame can stop draughts caused by gaps in the installation.
When is Replacement the Better Option?
While repairs can be effective, sometimes a full window replacement is the more sensible long-term investment. Consider replacement if:
- Your windows are over 15-20 years old and experiencing multiple issues.
- The frames are visibly damaged, warped, or rotting.
- You have single glazing or failed double-glazed units (condensation between the panes).
- Energy bills are consistently high despite making other home improvements.
Modern, high-performance windows offer vastly superior insulation, significantly reducing heat loss and making your home more comfortable.
The Impact of Draughty Windows on Your Bills
Draughts don't just affect your comfort; they hit your wallet too. When cold air leaks in, your heating system has to work harder to maintain a comfortable temperature. According to the Energy Saving Trust, replacing single glazed windows with A-rated double glazing could save you money on your energy bills every year.
