Bulk air movement through the ceiling, walls, and 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.
Of course, homes can also be too tight. CAZ uses a nationally-accepted process to determine how tight a home is, and how tight it should be. If a home needs air sealing, we use a blower door to guide our work, allowing us to find the smallest of leaks and to quantify our results.
