Air sealing is one of the most significant energy efficiency improvements you can make to your home.  Air infiltration occurs when outside air enters a house uncontrollably through cracks and openings.  Properly air sealing such cracks and openings in your home can significantly reduce heating and cooling costs, improve building durability, and create a healthier indoor environment.  As an energy services company, Sustainable Services specializes in meeting all of your home weatherization needs.


how weatherization can make your home more energy efficient

Sustainable Services will first test your home’s air leakage using the blower door. Based on those results, the following weatherization measures may be conducted to help seal those air leaks:

  • Caulking and weatherstripping doors and windows
  • Caulking and sealing air leaks around plumbing, ducting, and electrical wiring
  • Sealing dirty spots in your insulation, which indicate holes where air leaks into and out of your home
  • Using foam sealant around large gaps around windows, baseboards, and other places where warm air may be leaking out
