Air leaks can be uncomfortable, maybe even frustrating,…There’s a nip in the air.

And whether you live in the city or the suburbs, you don’t want the chill to come in with you — or your home’s warmed air to leak out — when you settle in for the night.

The fan pulls air out of the house, lowering the pressure inside, and allows the higher outside air pressure to flow in through cracks and other openings (the professionals typically use something called a smoke pencil, similar to the smoke test outlined above, to help spot the culprits; a blower door test not only locates air leaks but can also assess the overall air tightness of your home).

Now that you’ve found your home’s air leaks, it’s important to get familiar with the tools of the trade.

Caulk and spray foam are designed to help seal up stationary materials and fixtures like window frames (Energy recommends using caulk on holes 1/2 inch or less and spray foam on holes 1/2 inch to 3 inches).

A basement air sealing project might include using spray foam or caulk to seal cracks and openings in the basement walls, ceiling or floor.

You may also want to seal along the gap between the sill plate and the foundation and at the bottom and top of each rim joist (where cement walls meet the wood frame) at each end of the house.

Weatherstripping is meant for items that move, like doors and operable windows (between the frames and sashes).

You might also need a few specialty materials, like high-temperature caulk, metal flashing and reflective foils, depending on the project.

If you don't order the correct backset, your latches will either be too long or too short and you will not be able to mount your door hardware.

Some brands of door hardware like Schlage, Weiser, Kwikset, Sure-Loc and Weslock are shipped with adjustable backset latches which makes ordering easy.

An attic air sealing project might include creating pouches of fiberglass insulation to plug open stud cavities and gaps behind knee walls.
