Air sealing is one of the most cost-effective energy efficiency improvements a home or building can undergo. The many benefits of air sealing include: 

  • More even indoor temperatures 

  • Fewer cold drafts 

  • Healthier indoor air quality 

  • Less risk of condensation 

  • Lower energy bills

  • Better insulation performance

The Insulation Man prioritizes air sealing with every insulation project we complete. We take the time to do it right so that you can enjoy long-term home comfort and energy bill savings.


Where to Air Seal in a House 

Very few homes are airtight. Most are riddled with small openings, called air leaks, that allow air to flow into and out of the house without control. This is a huge problem that can greatly reduce the R-value effectiveness of any insulation that is installed and bring outdoor air pollutants into your home. 

Air leaks can be found just about anywhere in your home, although they are especially common in the attic, making air sealing your attic especially important. Other areas of concern include: 

  • Utility penetrations 

  • Seams between building materials

  • Windows and doors 

  • Recessed lighting 

  • Ceiling fans 

  • Chimney shafts 

  • Basement rim joists 

The Best Materials for Air Sealing a House 

At The Insulation Man, we utilize professional insulation and air sealing techniques and will identify the most cost-effective methods of improving your home or building's air barriers. We often use a combination of caulk, spray foam, and weatherstripping to air seal and weatherize a home.

In December 2010, I had my entire EJ home, including the basement insulated by The Insulation Man. Pat Dundon came highly recommended by several people. These recommendations did not disappoint.
