We like to share ways to help homeowners become more energy and cost efficient. If you have older windows or doors, there may be tiny air leaks in your house that are elevating your utility bill. Here are some tips for making your home airtight.

Finding Leaks

Air leaks waste energy and money because they allow air-conditioned or heated air to escape your house while letting outside air in. They can form anywhere but are commonly found around older doors and windows.

Here is a great do-it-yourself method for finding and fixing those leaks:

Pressurization Test

This works best on a cold, windy day.

  • Make sure all gas-burning furnaces and water heaters are turned off.
  • Turn on any exhaust fans that blow air out, such as bathroom fans, stove vents or clothes dryers.
  • Light an incense stick or candle and hold it around the edges of doors, windows or any other potential leak spots.
  • Keep your eye on the smoke. If it goes horizontal or is sucked out, you have found an air leak.

Fixing Leaks

Now that you have located the leaks, you are halfway through your journey towards saving energy. To patch the leaks, clean the area, then apply caulking or weather-stripping around the edges of doors, windows, or anywhere else you have detected seal failure. Once your weather-stripping has been installed and your caulking applied, your house will be more airtight.
