Using a blower door--a device that sucks the air out of your house to simulate an especially windy day--is the best way to identify where your house leaks. For many of us, a thousand little pin pricks may add up to a hole in your house the size of a window left open 24 hours a day, 365 says per year. 

By using a blower door in coordination with air sealing, we can identify the biggest leaks and get them sealed. 

This video from Green Building Advisor shows how it's done.

  • Thanks for recommending the home performance testing and air sealing of our house last fall. Air sealing was done and sealing completed in a day. The two employees at our home were most professional checking the house top-to-bottom for air leaks, while answering all my questions.
