How to Detect Air Leak in Windows

Old windows can be a major source of air leaks in your home, leading to drafts, higher energy bills, and discomfort. However, detecting these leaks can be tricky as they may not always be obvious. Here are some common ways to find air leaks in your home's old windows.

  1. Check for Drafts One of the easiest ways to spot air leaks is by feeling for drafts. Walk around your home with your hand near the window frames, and see if you can feel any cool air coming through. Pay special attention to areas around the window sash and sill. This can be especially noticeable during cold weather or windy days. If you do feel a draft, it's likely that air is leaking through the window.

  2. Use a Lit Candle or Incense Stick for a Smoke Test Hold a lit candle or stick of incense near the window frame and see if the flame or smoke flickers or is pulled towards the window. This can indicate an air leak. This method is particularly useful for pinpointing leaks around the window frame and seal.

  3. Use a Thermal Imaging Camera A thermal imaging camera can detect temperature differences, which can be a sign of an air leak. This is a more advanced method and may require the help of a professional. Thermal imaging cameras can detect heat loss through windows, which can indicate that air is leaking through.

  4. Use a Blower Door Test A blower door test is a professional method of detecting air leaks. It involves using a powerful fan to pressurize or depressurize your home, and then using a thermal imaging camera or other tools to detect leaks. A blower door test is a comprehensive method of detecting air leaks that can help you find leaks in hard-to-reach areas such as attics or crawl spaces.

  5. Look for Visible Signs of Damage Sometimes an air leak can be caused by visible damage to the window, such as cracks or gaps in the frame or seal. Make sure to perform a visual inspection of the window and surrounding area for any signs of damage. This can include rot, warping, and other forms of damage.
