Our seal of approval on these top spots to seal-

Written By Frank Caputo

“Common air leakage points to check and seal include:

  • The areas around plumbing, electrical, and duct work in exterior walls.

  • Any chases open to spaces like an attic.

  • Gaps between interior and exterior walls and ceiling sheetrock.

  • Any sheetrock areas, including between interior and exterior walls and where sheetrock is sealed to the subfloor.

  • Openings around windows.

  • Floors, including cantilevered floors and band joist areas in floor systems.

  • Kneewalls in cape-style structures.

  • Joints between existing buildings and additions or modular buildings.”
