Frequently Asked Questions about Aeroseal

Aeroseal® Duct Seal is guaranteed for 10 years in residential applications. Based on testing, you can expect your sealant to last for 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. An independent lab tested the sealant and found it to have an extremely low concentration of VOCs, which are present during the sealing process 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 must 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 settles in wall cavities, attics, or crawl spaces. During the process, we filter the air to capture any sealant entering living areas.

The sealant is not expected to harm any electronics, but we do encourage you to cover them, as a precaution.

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.
