Find the Air Leaks in Your Home

Leaks undermine the energy efficiency of your home by letting in air from the outdoors or by pulling the air you’ve paid to condition outside. In both cases, your energy bills go up. Finding the leaks and sealing them is the first step to take in making your home more comfortable and energy efficient.

Around Windows and Exterior Doors

Look for cracks around the window frames and exterior doors. Over time, the caulk around them can shrink, which lets air in from the outdoors. Weather permitting, remove the old caulk and reseal with new acrylic caulk.

Exterior door frames use weatherstripping to prevent air leakage. When it starts to wear out, it loses its effectiveness and needs replacing. Be sure you take a sample or a picture of the door frame to select the replacement material. Not all weatherstripping is the same.

Leaks in the Ceilings

Exhaust fans that vent through the ceilings are often the source of air leaks as are recessed lights in which the housing protrudes into the attic. Look for cracks between the fixture and the ceilings or feel for hot or cold air. You might even be able to see light coming through the cracks when the attic is dark.

Fireplace dampers are another area where air can easily leave or enter your home. A candle or incense stick will indicate whether there’s a draft coming from a leak. A new damper or chimney balloon will help seal it tightly.

Ductwork Leaks

Leaks in the ductwork can happen any time regardless of the age of your home. Look at the condition of the register covers for excessive dust and note any rooms you have that aren’t comfortable.
