Air Sealing

Simple and Effective
Air Sealing


Did you know that air leakage and improperly installed insulation can waste 20% or more of the energy used to heat and cool your home? That’s why air sealing is an important and cost-effective way to increase comfort throughout your home while minimizing your utility bill.

Effective air sealing blocks uncontrolled air flow into your home that can undermine even the most high-performance insulation systems. This will leave you with a quieter, more comfortable home that wastes less energy and lasts longer.

Cost, Payback and Incentives

The typical price range for professional air sealing is $250–$700. You can also save by doing your own air sealing — visit ENERGY STAR’s guide for more information.

An incentive of up to $200 may be available. Check with your local utility for offers and information about insulation, air sealing and other weatherization opportunities for your home.

Depending on factors such as the size of your home and the type of heating system you have, the simple payback period for air sealing is typically between 2 and 15 years. Effective air sealing should last for at least 40 years in a home.
