Air leaks throughout your home can contribute to significant wasted energy and money spent on utility bills while causing your home to lose some of its comfort. The simplest and most cost-effective way to get a better home environment is to identify sources of air leaks and to seal them.

Sealing Methods

Caulking: Caulk is a type of material used to seal air leaks in smaller, stationary gaps and cracks in your home.  When used around faucets, pipes, drains, and other plumbing fixtures, caulk can also help to prevent water damage.

Weatherstripping: Weatherstripping is used in moveable areas in your home like windows and doors. Weatherstripping comes in self-stick plastic, felt, foam, and other materials depending on the location where it is being applied.

Identifying and Sealing Air Leaks

  • Test your home for air leaks by checking windows, doors, outlets, ducts, ceilings, plumbing access panels, and anywhere else air may leak.
  • Pay close attention to your attic and basement where air leaks are common, including the attic entrance, recessed lights that vent into the attic, and the basement foundation.
  • Caulk or weatherstrip leaky doors and windows and leaks where plumbing, ducting, or wiring comes through your walls, floors, ceiling, etc.
  • A foam sealant can be used on larger gaps that exist around windows, baseboards, etc.
  • Use fire-resistant materials to seal leaks around fireplace chimneys, furnaces and other gas-associated areas.

Sealing air leaks not only helps to save energy and money but also helps with your home’s overall comfort. Sealed leaks can reduce mold, dust, pests, drafty rooms, and peeling paint, making your home a more comfortable and energy-efficient place year-round.
