Frequently Asked Questions about Aeroseal
Aeroseal® Duct Seal is guaranteed for 10 years in residential applications. Based on testing, the sealant has an expected life of at least 40 years
Our sealant is non-toxic; it has been used in hospitals, schools, surgery centers, and government facilities all over the world. The sealant has been tested by an independent lab and found to have an extremely low concentration of VOCs, during sealing time only. The primary component has NO OSHA maximum exposure limit.
The primary component in our sealant is Vinyl Acetate Polymer, which is commonly used in things like water-based paints, hair spray, and chewing gum.
Drying time is less than two hours.
There is a mild odor, like Elmer’s Glue, during sealing. The odor should dissipate by the next morning, if not before.
We prefer that no one is in the house during sealing primarily due to the impact on productivity. We want to complete the sealing process for you as quickly as possible. However, If you are pregnant, a senior citizen, have an infant in the home, or are utilizing medical equipment, we do encourage you to leave as a safety precaution.
Our sealing process can accommodate holes as large as 5/8” during the normal range of productivity.
Broken and disconnected ducts and large leaks need to be fixed prior to sealing. If a hidden, large leak is uncovered during sealing, the process will be halted while we discuss solutions with you.
Sealant escaping from the ducts will settle in wall cavities, attics, or crawl spaces. During the process, we will filter the air to capture any sealant entering the living areas.
We recommend that sensitive electronics be covered.
Ducts of all material types can be successfully cleaned after sealing
The Aeroseal process does not coat or line the ductwork. The only sealant remaining in the ducts will be at locations where leaks were found prior to sealing.
