Sealing air leaks in your home

Man!  It is cold out.  I know in my home there are certain areas I can feel the cold air sneaking in.  Here are a few easy do-it yourself projects to help keep the cold out…

Caulking, sealing and weather-stripping all seams, cracks, and openings to the outside, will reduce air leaks in your home and reduce your heating and cooling bills.

The US Department of Energy recommends the following steps to seal air leaks in your home:

  • First, test your home for air tightness. On a windy day, carefully hold a lit incense stick or a smoke pen next to your windows, doors, electrical boxes, plumbing fixtures, electrical outlets, ceiling fixtures, attic hatches, and other locations where there is a possible air path to the outside. If the smoke stream travels horizontally, you have located an air leak that may need caulking, sealing, or weather-stripping.
  • Caulk and weather-strip doors and windows that leak air.
  • Caulk and seal air leaks where plumbing, ducting, or electrical wiring penetrates through walls, floors, ceilings, and soffits over cabinets.
  • Install foam gaskets behind outlet and switch plates on walls.
  • Look for dirty spots in your insulation, which often indicate holes where air leaks into and out of your house. You can seal the holes with low-expansion spray foam made for this purpose.
  • Look for dirty spots on your ceiling paint and carpet, which may indicate air leaks at interior wall/ceiling joints and wall/floor joists. These joints can be caulked.
