How to Seal up Air Leaks in your Home

How to Seal up Air Leaks in your Home

During the hottest months of summer, you will want to stay cool and comfortable in your home. This doesn’t have to come at a high price, however. The largest energy expense typically comes from your heating and cooling bills. There are ways that you can minimize these bills so that the expense is not costing you significantly just to stay comfortable and cool.  We’ll walk you through ways that you can check your home for any air leaks that could be costing you extra unnecessary money and energy.

How To Test for Air Leaks

  • First, check the windows and doors in your home to make sure there aren’t any that are cracked open.
  • Next, evaluate the weather stripping. If you have deteriorating weather stripping in your home, peel it away and make sure to clean the surface so that it’s ready for new weather stripping. It’s time to apply new weather stripping (that’s waterproof) to the doors and windows in your home.
  • Seal the Air Ducts in your home with mastic sealant.
  • Perform a test for air leaks by using thin toilet paper or an incense stick. Hold it next to your doors, utility connections, windows or ceiling fixtures to check if there’s an air leak. When you perform this test, turn off the air conditioning system so that the air is still. If the thin toilet paper or the smoke begins to move at all when you hold it up, that means there’s an air leak.
  • Check the flue of your fireplace when checking for air leaks as well. The flue should create a tight seal when it’s not being used and most people don’t think about how much air comes in and out through your fireplace!
  • Also, check the outlets in your home. It may be a good idea to purchase foam gaskets to seal the air leaks so that air is not escaping through the outlets.

Other things to remember:

  • The door sweeps in your home should be checked and replaced if necessary. When shopping for new door sweeps, look for the permanent pliable rubber sealants. These are a sturdy option compared to the self-adhesive type of door sweep.
  • Moving to the outside of the home, check the full perimeter for any gaps that you may find. If the gaps are larger than ¼ inch, you can spray them with expandable foam spray to fill in the gaps.

These are all ways that can help seal up the leaks in your home so that precious air and heat doesn’t escape. While you may be able to do some of these yourself, it’s always best to call a professional to handle the task of making sure that your whole home is properly sealed. Call Central Carolina Air Conditioning, Plumbing & Electrical to inspect your duct work to test for any leaks.  If it was installed improperly, if the duct work is old, or if there’s corrosion, these could all contribute to leaks in the duct work.  Interested in learning more about how we can take of your whole house with our Whole House program?
