What Is the Air Sealing Process?

Technician setting up a red blower door in a home's front doorway.Air leakage, or infiltration, is outside air that enters a house through cracks and openings.

The recommended strategy in both new and old homes is to reduce air leakage as much as possible and provide controlled ventilation as needed.

Air sealing involves using a blower door, which includes a fan that pulls air out of the house and allows outside air to flow in through unsealed cracks and openings.

With smoke pencils, our mechanics can find these leaks and seal them. This helps homeowners reduce energy consumption and prevent moisture condensation problems, uncomfortable drafts and uneven heating or cooling.

What Are the Biggest Sources of Energy Loss?

Although windows, doors and outside walls contribute to air leakage, the biggest holes are usually hidden and connect the house to the attic, crawl space or basement.

The key is to identify these areas during the design process, assign responsibility for sealing holes and check to make sure the air sealing was done effectively. Usually, all big holes are sealed first, then the large cracks and penetrations and, finally, the smaller cracks and seams.

What Are the Benefits of Air Sealing?

Air infiltration can account for 30% or more of a home’s heating and cooling costs and contribute to problems such as:

  • Moisture infiltration
  • Mold and mildew development
  • Infiltration of dust, pollen and other debris
  • And more

Reducing infiltration can help significantly cut annual heating and cooling costs, improve interior comfort and contribute to a healthier indoor environment.
