Air Sealing a home is one of the most cost-effective ways to make a home more comfortable and energy-efficient. Air leakage through windows, doors, walls, rim bands, floors and ceilings has been shown to increase heating and cooling costs 35-40%. For the average American home, it's like having a 2' x 2' window open ALL THE TIME!
Unsealed chases and cavities in attics and crawl spaces bring unconditioned and unfiltered air into living areas. Sealing these air leaks will not only make your home more comfortable and energy efficient – it'll improve the quality of the air you breathe.
