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.

  • I'm pleased to share a word of appreciation for the work A-A Exteriors did for our condo association. They conducted a blower-door test for our six-building, sixty units. This was a complex project.
