Improve your building's Indoor Air Quality (IAQ)

Indoor air quality (IAQ) is a huge factor in the health and well being of a building's occupants.

The average office worker spends up to 90% of their time indoors, where experts estimate air contaminants can be 50x worse — thanks to leaky ductwork.

How does leaky ductwork affect IAQ?

Leaks in the return duct allow contaminants to be sucked into the duct system and spread from one area throughout the rest of the facility.


Leaks in the ventilation shaft reduce exhaust fan effectiveness in sucking dirty and stale air out of the building. This leads to mold and mildew issues which also hurts IAQ.

A Turnkey Solution

Aeroseal’s proven technology works from the inside of the ducts to locate and seal the leaks causing poor IAQ. No tearing down walls or stripping off insulation. In fact, multi-floor buildings can be treated with Aeroseal without disruption to its occupants.
