How Blower Door 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. 

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.

Video: Exterior Wall Insulation Retrofit

This video from our friends at Go Green Star explains how to insulate a home's walls from the exterior, for improved energy performance and reduced energy bills, with minimum intrusion.  Depending on the type of siding on your home the process can be more or less labor intensive.  Our company prides itself on spending a little extra time to make sure the holes are drilled evenly, the plug and patch work is done properly, and that you are given all the information you need to either paint the patches yourself or hire a local painting expert to help you.  Our installation technicians have spent years perfecting their craft and do an excellent job to ensure the job is done right.
