Detecting Leaks

Energy Audit

For a thorough and accurate measurement of air leakage in your home, hire a qualified technician to conduct an energy audit, particularly a blower door test. A blower door test, which depressurizes a home, can reveal the location of many leaks. A complete energy audit will also help determine areas in your home that need more insulation.

Without a blower door test, there are ways to find some air leaks yourself. First, look at areas where different materials meet, such as between brick and wood siding, between foundation and walls, and between the chimney and siding. Also inspect around the following areas for any cracks and gaps that could cause air leaks:

    Door and window frames
    Mail chutes
    Electrical and gas service entrances
    Cable TV and phone lines
    Outdoor water faucets
    Where dryer vents pass through walls
    Bricks, siding, stucco, and foundation
    Air conditioners
    Vents and fans.

You can also try these steps to depressurize your home to help detect leaks:

    Turn off your furnace on a cool, very windy day.
    Shut all windows and doors.
    Turn on all exhaust fans that blow air outside, such as bathroom fans or stove vents.
    Light an incense stick and pass it around the edges of common leak sites. Wherever the smoke is sucked out of or blown into the room, there's a draft.

If you don't want to turn off your furnace, you can just turn on all your exhaust fans to depressurize your home.

Other air-leak detection methods include the following:

    Shining flashlight at night over all potential gaps while a partner observes the house from outside. Large cracks will show up as rays of light. Not a good way to detect small cracks.

    Shutting a door or window on a piece of paper. If you can pull the paper out without tearing it, you're losing energy. You may as well just shove some $10s and $20s through those cracks while you're at it.
