How Blower Door and Infrared Assisted Air Sealing Helps Find Leaks

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. 

We go around the home with a smoke pen, hands/feet or the infrared camera, to see and feel all of these leaks. Determining where the majority of thes leaks are allow us to pinpoint the best places to eliminate the issue. If doors or windows are proving to be the problem we know some simple weatherstripping and caulk will solve the problem. However, most of the time it shows us hidden leaks behind the walls that connect our living spaces with the hot,humid and dirty air of the attic!

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