Aeroseal

Aeroseal is an advanced duct sealing technology that seals air leaks from the inside of your ductwork. Instead of relying on tape or mastic applied to the outside, Aeroseal uses a safe, nontoxic aerosolized sealant that travels through your system and automatically seals leaks wherever air is escaping.

The result is a tighter, cleaner, more efficient duct system — with verified, measurable improvements in performance.

How Aeroseal Works

Traditional duct sealing methods can miss hidden gaps and hard-to-reach connections. Even well-applied mastic can leave small leaks behind. Aeroseal solves that problem by sealing your ducts from the inside out.

Here’s what the process looks like:
  1. Isolate & Test – We temporarily seal off vents and pressurize your duct system to measure current air leakage.
  2. Seal from the Inside – Using a specialized Aeroseal machine, we inject microscopic sealant particles into the ductwork.
  3. Targeted Sealing – As air escapes through leaks, the particles are drawn to those gaps and bond together, sealing them precisely where needed.
  4. Verify Results – We retest the system and provide proof of the reduction in air leakage.

No guesswork. No tearing into walls. Just measurable results.

Why It Matters

Leaky ductwork can waste a significant amount of the air your HVAC system works hard to produce.

That means:
  • Higher energy bills
  • Uneven temperatures
  • Reduced airflow to living spaces
  • Conditioned air escaping into basements, attics, or wall cavities

For new construction, renovations, and Energy Star homes, duct leakage must be kept below strict thresholds, often under 5%. Aeroseal helps achieve those standards and ensures your home’s thermal envelope works the way it was designed.

Built for High-Performance Homes

If you’ve invested in a new build, a full renovation, or your “forever home,” Aeroseal ensures your heating and cooling system performs at its highest level.

A tighter duct system means:
  • More consistent comfort
  • Improved indoor air quality
  • Greater system efficiency
  • Less strain on HVAC equipment
