Do your floors get cold in the wintertime? Do you find that no matter how high you crank the heat, you never seem to get to the right temperature? You may want to look in your basement for air leaks. Sealing leaks means you're going to keep more conditioned air in your home and the outside air outdoors where it belongs.

Air sealing is easy once you know where to look. There are three places where air leaks occur in a basement.

  1. Where the masonry foundation meets the wood.
  2. Gaps between the wood up to the bottom of the floor.
  3. Any place where something goes in or out of the house, such as wiring or pipes.

You can use caulk to seal gaps, or expanding foam. Expanding foam is really handy because you spray just a little in the gap and it expands to fill it in. It may take a little while, but the time you spend fixing leaks can pay big dividends.  

Check your basement and see if you have air leaks. If you do, try a little air sealing of your own. It will make your home more comfortable and efficient.
