Get Started

Our AeroSeal Duct Sealing Process

Step 1: Duct Cleaning
We begin by performing a full duct cleaning, which is a complimentary part of our service. This helps prepare the duct system before sealing begins.

Step 2: Pre-Seal Leakage Test
Next, we perform a pre-seal test to measure the amount of air leaking from your duct system.

Step 3: AeroSeal Application
We pressurize the duct system and release the aerosol sealant. The sealant travels through the ductwork and accumulates at leak points, sealing them from the inside.

Step 4: Post-Seal Testing
After sealing is complete, we perform a second test and provide before-and-after leakage measurements so you can see the results.

What to Expect During Your Appointment

Most AeroSeal services take approximately 6–8 hours to complete. Our team will walk you through the process beforehand and answer any questions, so you feel comfortable every step of the way.

To perform the service properly, our technicians will need:

  • Access to the entire home or building
  • The ability to block off all vents during the sealing process

During the aerosol application:

  • The sealant is typically applied mid-day to early afternoon
  • We recommend leaving the home briefly to run errands or grab lunch
  • Birds and reptiles cannot be present in the home during the spraying portion

Advanced Duct Sealing with AeroSeal Technology

AeroSeal is an automated technology designed to seal leaks in ductwork for both residential and commercial buildings.

This process uses a patented, non-toxic aerosol sealant distributed throughout the duct system while it is pressurized. As air escapes through leaks, sealant particles travel directly to those leak points and collect there, sealing them from the inside without coating the entire duct.

Because the sealant is carried by escaping air, AeroSeal can reach leaks that are difficult to locate or repair with traditional duct sealing methods.
