Tips for sealing air leaks

As the autumn air turns crisp, it’s time to make sure your home’s air leaks are sealed properly to keep winter winds away. Here, Burke-Divide Electric Cooperative shares information on properly sealing air leaks.

 

Tips for sealing air leaks

  • Test your home for air tightness.
  • Caulk and weatherstrip doors and windows that leak air.
  • Caulk and seal air leaks where plumbing, ducting or electrical wiring comes through walls, doors, ceilings and soffits over cabinets.
  • Install foam gaskets behind outlet and switch plates on walls.
  • Inspect dirty spots in your insulation for air leaks and mold. Seal leaks with low-expansion spray foam made for this purpose and install house flashing if needed.
  • Look for dirty spots on your ceiling paint and carpet, which may indicate air leaks at interior wall/ceiling joints and wall/floor joists, and caulk them.
  • Cover single-pane windows with storm windows or replace them with more efficient double-pane low-emissivity windows.
  • Use foam sealant on larger gaps around windows, baseboards and other places where air may leak out.
  • Cover your kitchen exhaust fan to stop air leaks when not in use.
  • Check your dryer vent to be sure it is not blocked.  This will save energy and may prevent a fire.
  • Replace door bottoms and thresholds with ones that have pliable sealing gaskets.
  • Keep the fireplace flue damper tightly closed when not in use.
  • Seal air leaks around replace chimneys, furnaces and gas-fired water heater vents with re-resistant materials.
