What Is Aeroseal Duct Sealing?
Aeroseal is a patented, state-of-the-art method that seals leaks in your ductwork from the inside out. Rather than manually hunting for every crack, we pressurize the duct system with a safe aerosol sealant that finds and plugs leaks automatically.
How the Process Works
- Inspect & pre-test — We measure how much air is leaking today.
- Seal off registers & protect equipment — All vents and registers are blocked so air is forced through leaks.
- Introduce the sealant — A fine aerosol mist circulates through the ducts.
- Seal leaks internally — The particles accumulate at leak edges until they seal them.
- Post-test & report — We compare before/after leakage and deliver a performance report.
- Restore & cleanup — All access points are patched and the system is returned to normal.
Because the sealant is low-VOC, code compliant, and only accumulates where needed, it doesn’t coat the entire duct interior — it targets leaks.
Benefits You’ll Notice

FAQs
Is the Aeroseal sealant safe?
Yes. It’s a water-based, ultra low VOC (volatile organic compound) emulsion tested for safety.
What size leaks can it seal?
Aeroseal can reliably seal leaks up to 5/8″ diameter. Larger openings may need manual repair first.
Will I be home during the work?
You may stay home, but we sometimes recommend vacating during the process so installers can move freely.
Do ducts need to be cleaned first?
If needed, yes. We will inspect and recommend cleaning if there’s dust, debris, or build-up.
How long does the seal last?
Residential systems often get a 10-year warranty, and the sealant’s expected life is 40+ years.

FAQ
How long does Aeroseal take?
Most homes are sealed in a single visit, typically a few hours depending on size and access.

Yes—water-based, ultra-low VOC, and it only accumulates at leak points.
Do you clean ducts first?
If dust/debris is excessive, we’ll recommend cleaning prior to sealing for best results.
How long does it last?
Aeroseal’s seals are designed for multi-decade performance under normal operating conditions.
Will this fix hot/cold rooms?
Sealing usually improves airflow balance significantly. We can also adjust dampers or recommend minor duct mods if needed.
