Air Sealing

Air sealing a home is the most important step in making an energy efficient home. Air sealing consist of sealing all gaps and penetrations to the exterior of a house to stop air infiltration. This includes light fixtures, plumbing penetrations, windows, doors, attic scuttles, etc. With the help of infrared imaging we can asses your home to find hidden leaks and combat the unseen problems. Insulation is useless unless air movement is stopped.
