Aeroseal® Duct Sealing

Frequently Asked Questions

  • How Many Homes Have Been Aerosealed? As of the end of 2013, nearly 100,000 homes have been sealed, with over 200 more homes being sealed every week.
  • What Is The Sealant Used With The Aeroseal Process?​Aeroseal’s proprietary sealant is a vinyl acetate polymer, which is the same substrate used in hairspray and chewing gum as a base.
  • Does It Harden After Application? No. The sealant remains flexible and malleable.
  • Is There An Odor? At the time of application, there is a very mild odor, similar to that of Elmer’s glue. However, that dissipates within a few hours.
  • Will The Ducts Be Covered With Sealant? Aeroseal does not coat the ductwork—it finds the pressure change across the leaks and seals it.
  • How Long Will It Last? Aeroseal has gone through multi-year testing with no signs of failure and is expected to last for many decades. Also, the Aeroseal result if guaranteed for 10 years.
  • Is It Safe? Aeroseal’s material is non-toxic and the main ingredient is used in water-based paints, hair sprays, and chewing gums. The material is approved by the state of Florida for use in your home.
  • How Long Does It Take To Dry? Drying time for the Aeroseal material is less than 2 hours.
  • What About Leaks That Are Too Big? A broken or disconnected air duct may need to be fixed before sealing. If a hidden leak is uncovered during sealing, the process stops and we will discuss a solution with you before proceeding.
  • Where Does The Sealant Leaking From The Ducts Go? The material escaping from the ducts will settle in your wall cavities, attics, or crawl spaces. During the process, fans capture any material leaking into your home.
