Draughty Windows? How to Spot the Signs and Fix the Problem

Writer's picture: Tina MillerTina Miller

Are you feeling a chill breeze even when your windows are closed? Do your energy bills seem suspiciously high? You might have draughty windows. This common problem can make your home uncomfortable and expensive to run. But don't despair! This blog post will help you identify the signs of draughty windows, explore the common causes, and guide you through the best solutions, including whether it's time for a replacement.


A Quick Note on Perception: It's worth noting that our perception of a draft can sometimes be influenced by temperature differences. Even with perfectly sealed windows, a temperature difference of 4 degrees Celsius or more between the inside and outside of your home can make you feel like there's a draft, even if there isn't one. So, while a perceived draft is a good starting point, it's important to look for other signs to confirm if your windows are truly draughty.


Spotting the Signs of Truly Draughty Windows:

It's not always obvious that your windows are the source of those chilly drafts. Here are some telltale signs to look out for, beyond just feeling a chill:

  • Visible Gaps:  Inspect your windows closely. Can you see any gaps or cracks between the frame and the window itself, or between the frame and the wall? This is a clear indication of potential air leakage.

  • Feeling a Consistent Draft:  Stand near your windows on a windy day. Consistently feeling a draft, even when the windows are closed, suggests a problem. Remember to consider the temperature difference mentioned above.

  • Rattling Windows:  Do your windows rattle in the wind? This could indicate loose or damaged seals, allowing air to pass through.

  • Condensation Problems:  While condensation can have multiple causes (as discussed in our previous blog!), excessive condensation, especially between the panes of double-glazed windows, can be a sign of a broken seal and reduced insulation performance. Condensation on the outside of the glass is often perfectly normal and a sign of good insulation.

  • High Energy Bills:  Have you noticed a steady increase in your energy bills, even though your usage hasn't changed significantly? Draughty windows can significantly contribute to heat loss, forcing your heating system to work harder.

  • Cold Spots:  Do you notice certain areas of your home, particularly near windows, are significantly colder than others? This can be a sign of poor insulation or air leakage.

  • Water Leaks:  Are there signs of water leaking through or around your windows, especially during heavy rain? This can damage your walls and lead to mould growth.


Common Causes of Draughty Windows:

Several factors can contribute to draughty windows:

  • Old or Damaged Seals:  The seals around your windows are designed to prevent air leakage. Over time, these seals can deteriorate, crack, or become brittle, allowing drafts to penetrate.

  • Poor Installation:  Windows that weren't installed correctly can leave gaps and create draughts. This is why professional installation is crucial.

  • Warped or Damaged Frames:  Window frames can warp or become damaged due to age, weather exposure, or impact. This can create gaps and allow air to leak through.

  • Single-Glazed Windows:  Single-glazed windows are significantly less energy-efficient than double or triple-glazed windows and are much more prone to draughts and condensation.

  • Outdated Window Technology:  Older double-glazed windows may have lost their insulating gas between the panes, reducing their effectiveness and leading to draughts.


Fixing Draughty Windows: What Are Your Options?

The best solution for draughty windows depends on the severity of the problem and the age of your windows. Here are some options:

  • Replacing Seals:  If the seals around your windows are the only issue, replacing them might be a cost-effective solution. However, this is often a temporary fix, especially for older windows.

  • Weather Stripping:  Applying weather stripping around the edges of your windows can help reduce drafts. This is a DIY option, but it's important to choose the right type of weather stripping and install it correctly.

  • Window Repair:  In some cases, it might be possible to repair damaged window frames or other components. However, extensive damage might make replacement a more sensible option.

  • Window Replacement:  If your windows are old, single-glazed, or significantly damaged, replacing them with new, energy-efficient windows is the best long-term solution. This offers the greatest improvement in energy efficiency, comfort, and home value.
