Air sealing is one of the most cost-effective ways to boost efficiency and save money in your home or business.
Air sealing can save an average of $375 a year in home heating and cooling costs. If done properly, air sealing reduces the risk of moisture-related mold and rot, and boosts personal comfort by eliminating drafts. The most common air leakage points are in your attic and basement (windows, doors, and heating ducts are also frequent culprits). The average home has enough cracks and openings, that when combined, equate to a two-foot-square hole. Leaving them unsealed is like leaving a window open all year long.
