What is Air Sealing? 

Air sealing is an energy efficiency home upgrade that every homeowner should be aware of. The service is done in the attic and crawl space to ensure there are no air leakages that cause energy loss and increasing utility bills. Air sealing is essentially blocking gaps and cracks around light fixtures, vents, pipes, and electrical wiring to prevent air transfer. Many homeowners may think it is not a big of a deal but when combining all these gaps and cracks together it’s like having a 2 ft x 2 ft window open in the house which results in a huge energy loss. Experts saying “Air sealing is the secret sauce to make people more comfortable in their homes”. New building codes like “Title 24” requires the contractor to air seal the attic and crawl space in new construction projects as well as attic and crawl space retrofitting.
