Sealing Your Minneapolis Home

Air sealing entails closing up leaks in houses to keep warm or cool air from escaping to the outside. A home’s envelope (exterior)—including the walls, roofing, foundation, windows and doors—has many small cracks and crevices through which air leaks out.

Too many air leaks left unsealed can lead to problems such as:

  • A drafty, uncomfortable home interior
  • Higher energy bills
  • Excess moisture and mold development
  • Window damage (like sill deterioration)

Two common air sealing methods are caulking and weatherstripping. Caulking is typically used for cracks and crevices between stationary house parts, while weatherstripping is used for moving components, like windows and doors.

Common Air Leak Sites

Air leaks most frequently occur in:

  • Walls
  • Windows and doors
  • Attic
  • Place where siding and chimney meets
  • Electrical outlets
  • Fireplace dampers
  • Place where dryer vents enter the wall
  • And more

Benefits of Air Sealing

Air sealing offers a lot of benefits for your home. It can help:

  • Lower your energy bills: If leaks are sealed up (and your home is properly insulated), your HVAC systems won’t have to work as hard, which can help lower your monthly utility bills and extend the lifespan of your heating and cooling systems.
  • Increase year-round home comfort: Air leaks can cause a lot of drafts in your home, so sealing can eliminate them and help increase overall comfort levels (as well as reduce outside noises).
  • Improve indoor air quality: If your home’s envelope isn’t properly sealed, there’s a higher risk of air pollutants, pollen, dust, etc. leaking in and decreasing the indoor air quality. This can have negative effects on your health and everyday comfort.
  • Reduce home damage: Sealing air leaks can help eliminate problems in your home, such as moisture infiltration, mold growth, insulation damage, etc.—which is good for the durability of your home.
