Bulk air movement across a structure’s pressure boundary (typically walls, ceiling, floor) is often one of the greatest sources of heat loss in a home.  On top of that, air movement across these surfaces can lead to other problems such as poor indoor air quality, ice damming, and condensation in your attic.
CAZ uses a blower door to guide our air sealing, allowing us to find non-obvious leaks and to quantify our results.  A few hours with a blower door, some backer rod, and a foam gun can go a long way to making a home more efficient, durable, and healthier for its occupants.
