Air Sealing



Air sealing is one of the most significant OneThings you can do in your home. It will not just reduce energy costs, it will also improve your home's comfort. And the best part is, many air sealing techniques are cheap and easy to do.

What is Air Sealing?

It's a general term for properly sealing cracks, holes and other small openings in your home to keep outside air from leaking in, causing your heating or cooling systems to have to work harder and use more energy.

Air Sealing Tools

The most common tools are caulk and weather-stripping. In fact, there are literally hundreds of different weather-stripping products out there for just as many different air sealing applications. Plus, there's expanding foam, outlet and switch plate gaskets, window film, even those long, thin beanbags you put at the bottom of your doors to stop drafts. Talk to your retailer to learn more about using these products.

Finding Air Leaks

For a thorough and accurate measurement of air leakage in your home, you can hire a qualified technician to conduct an energy audit. On your own, you can find many leaks with your bare hands. In the winter especially, feel around places you think a draft or leak might be and you'll likely notice cold air coming in.

Here are some common areas where leaks occur:
  • Where different materials meet, like between brick and wood siding, between foundation and walls, and between the chimney and siding.
  • Door and window frames
  • Mail chutes
  • Outlets and switch plates
  • Electrical and gas service entrances
  • Cable TV and phone lines
  • Outdoor water faucets
  • Where dryer vents pass through walls
  • Damaged bricks, siding, stucco and foundation
  • Air conditioners
  • Vents and fans
