Air Sealing

Air leaks rob your home of energy and comfort. Find and seal up leaks for a safer, more comfortable and energy efficient home — and earn up to $150 back.

Even when you don’t feel a draft, air leaks may be letting heated or cooled air out of your home — and letting unwanted pollutants inside. Sealing leaks is an inexpensive, effective way to lower heating and cooling costs, increase comfort, improve durability and create a healthier home.


Get $150 cash back on air sealing when you work with a BayREN Participating Contractor.
