What Is Aeroseal Duct Sealing?

How Aeroseal Duct Sealing Works

Aeroseal is a modern method of sealing air leaks in your duct system from the inside, without needing to tear into walls, ceilings, or ductwork.

Instead of manually sealing ducts, the process uses a specialized machine to push a fine mist of sealant through your system. The sealant particles travel through the ducts and stick to the edges of leaks, sealing them over time.

Here’s how the process works:

• Your duct system is tested to measure how much air is leaking
• Vents and registers are temporarily sealed off
• The Aeroseal system injects sealant into the ducts
• The sealant collects at leak points and closes gaps from the inside
• A final test confirms how much leakage has been reduced

This method can seal leaks that are difficult or impossible to reach with traditional duct sealing.

In homes across Fredericksburg, Kerrville, and the Texas Hill Country, duct leaks can lead to uneven temperatures, higher energy bills, and reduced comfort. Aeroseal offers a way to improve system performance without major disruption to your home.

It’s often used as part of a larger effort to improve airflow, efficiency, and indoor air quality.
