You’ve probably heard the expression, when someone leaves a door open on a cold day, “hey, we can’t afford to heat the outside!” Yet, that’s exactly what you’re doing if your home has substantial air leakage. Gaps and cracks in a house’s outer envelope allow warm air to infiltrate a home in the summer and escape from the same house in the winter. This forces your HVAC system to work all the harder to heat and cool your home, wasting energy and landing you with higher utility costs.
Fortunately, homeowners can address this problem by finding and sealing air leaks in a home’s outer envelope, either by way of a do-it-yourself energy audit or hiring a trained professional to do perform a comprehensive energy assessment.
Walk around the outside of your home, paying special attention to areas where air leakage is likely to occur. This includes the sill plate (where the drywall and foundation connect), other places where building materials meet, door and window frames, and locations where utility pipes, wires, vents and flues enter the home.
Inside the house, patrol the interior of outer walls with a lighted smoke pencil or incense stick. Pass the smoke in front of likely air leak locations, and watch for the smoke to waver. This points to a possible air leak.
Professional Energy Audit
A professional technician, using high-tech diagnostic equipment, can determine where air is leaking from your home, as well as where insulation is lacking. They’ll prepare a report identifying the problem and recommending a plan of action for remedying it.
Sealing Air Leaks
Once you know where air is leaking from your home, you can seal air leaks yourself. Depending on their type, size and location, air leaks in your home’s outer envelope can be sealed with caulk, weatherstripping or spray foam insulation. These sealants typically come with detailed instructions for how to use them, along with recommendations for what sort of tools are necessary for proper application.
