The attic and basement are where most of the air leaks in a home occur, wasting hundreds of dollars worth of energy each year. By improving the air sealing in these areas and adding insulation, homeowners can save energy, keep their homes cooler and healthier, and reduce home maintenance costs.

Proper Attic Sealing Before Insulation

Before any insulation is installed, all attic openings, such as access hatches, pull-down stairs, and knee walls, should be sealed with caulk or expandable foam spray. Also, any active knob and tube wiring should be replaced and/or properly boxed before proceeding with attic work. In addition, the attic should be inspected to ensure adequate ventilation.

Leaky attic ductwork can allow conditioned air to escape into the attic, which will make the rest of the house more expensive to heat and cool. Look for leaks around duct connections using your hand, a lit incense stick, or a piece of paper, and seal with mastic sealant paste or foil HVAC tape. You can wrap leaking ducts with insulated sleeves for an extra boost in efficiency.

Use GE Advanced Silicone Window & Door Sealant to seal cracks, gaps, and joints that are exposed to seasonal temperature changes, as well as around plumbing vents, utility cutouts, and framing. For larger gaps, use GE Multipurpose Foam, which expands to fill irregular spaces and creates a durable, airtight seal that blocks pest entry. For a finished, attractive appearance, trim the excess with a utility knife.
