Where to look for air leaks?
Cold and windy weather makes air leaks most noticeable. We usually say that a house is drafty, but what that actually means is that there are many air leaks in it, allowing warm air to escape, and cold air to enter the house. Even though it’s easiest to feel air leaks around windows and doors, the most significant air leaks are usually in the attic and basement.
In general, troublesome areas are places where two building materials meet and wherever there are visible cracks and gaps. Here are the specific areas that Energy Star and other expert sources warn about:
- In the attic: kneewalls, the hatch
- Open soffit (where recessed lights are)
- Basement rim joists
- Dryer vent
- Crawl space
- Plumbing vent stack
- Flue and fireplace dampers
- Duct chaseway (or wall chase)
- Duct registers
- Window and door frames
- Wiring holes
- Electrical outlets and switch plates
What can you do about it?
By plugging air leaks around your home, you could bring your monthly energy costs by 30%. Here are some ideas:
- Caulk and weatherstrip doors and windows
- Caulk holes where wiring, plumbing or ducting goes through walls, floors and ceiling.
- Use foam gaskets for outlets and switch plates.
- Use expanding foam to seal larger gaps around windows, doors and baseboards.
- Cover kitchen exhaust fan when it’s not in use.
- Add pliable sealing gaskets to door frames.
- Use sheet metal, sheetrock or fireplace cement caulk to seal gaps around chimneys and fireplaces.
