Air Leak Sealing Information

Sealed Air Leaks

Sealed Air Leaks
Spend $554 now and SAVE $180 each year.. RIO = 32.5%


Have a professional seal your home's air leaks. Typically, this reduces air leakage by 25%.

The U.S. Department of Energy (DOE) estimates that air leakage accounts for up to 10 percent of a homeowner’s annual energy bill, or about $70 per year for an average U.S. household. Your top priorities are sealing the attic, then basement, followed by windows, doors, vents, electrical sockets, and anywhere else air is escaping.

To help find leaks, hire a professional to pinpoint them with a blower door test or infrared technology. If you properly seal your house in addition to insulation, you may even be able to downsize your heating and cooling systems.

The ROI Calculation is based on using a professional service provider, and savings of $15 a month over the course of the year. If you take the time to find and seal the air leaks yourself, the ROI naturally goes up.

DIY Tips

If you are having difficulty locating leaks, you may want to conduct a basic building pressurization test: First, close all exterior doors, windows, and fireplace flues. Turn off all combustion appliances such as gas burning furnaces and water heaters. Then turn on all exhaust fans (generally located in the kitchen and bathrooms) or use a large window fan to suck the air out of the rooms. This test increases infiltration through cracks and leaks, making them easier to detect. You can use incense sticks or your damp hand to locate these leaks. If you use incense sticks, moving air will cause the smoke to waver, and if you use your damp hand, any drafts will feel cool to your hand.
  • Close the Damper - Shut the damper on your wood burning fire place in the winter to restrict the warm air from leaving your home. Naturally, open it if you use the fireplace!
  • Lock the Windows (Summer & Winter) - Reduce air leakage, secure on casement windows and the horizontal space between the upper and lower sash on double hand windows.

Good to Know

Naturally, homes with major window deterioration may cost more to seal. For DIY home improvement look for air leakage in the most common areas: Window frames, Baseboards, Weather stripping around doors, Fireplace dampers, Attic hatches, and Wall- or window-mounted air conditioners. Plus all of the little things add up. Electrical outlets and Switch plates often leak air even though you may not feel it, because the insulation does not hug the junction box in the wall. Foam backers are cost effective and take just a minute to put in by unscrewing the cover plate.

Attic Entrances - Any attic entrance, whether a pull down ladder, push up hatch, knee wall panel or permanent staircase is a big source of air leakage at exactly the right high point in your house to waste $50 to $250 a year of your heating and cooling costs. Because they are made of drywall or plywood, they will inevitably warp over time making the air leakage even greater. That ...
