We offer air sealing as a standard service.

There are certain areas of the attic and crawlspace where insulation alone may not be able to stop air from leaking into and out of your home. Take a look at some sites where air leakage may be lessened with air sealing.

through the Home Performance with Energy Star Program.

Warning: Through our experience, it is difficult to reach target goals for utility Home Performance with Energy Star program by doing air sealing yourself. Homes should have atleast a minimum starting NACH of 0.50 or greater to have a good probability of success. Of those homes: air sealing of crawlspaces and extensive air sealing of the attic should be done. Insulating attic and walls should also be done to help reach this goal in our oppion. (Remember to follow the IRC 2006 Code+ & moisture safety practices).

NACH = Natural Air Changes Per Hour (The percentage of air that leaves your home every hour).
