Aeroseal Duct Sealing

Danforth Aeroseal Duct Sealing Service

Danforth is an official provider of Aeroseal Duct Sealing Services. This groundbreaking technology allows us to seal any leaks in your air duct from the inside. As the safe polymer is injected into the duct, it begins adhering to the edges of the leak and then compounds together to form the seal. We are able to seal any leaks without dismantling your air ducts, which reduces downtime and labor cost.

Leaking air ducts cause stress to your HVAC system. Like contaminant build up, the leaks make your system work harder to maintain a comfortable environment in your building while using more energy. This can lead to shortened equipment life and increased energy bills.

Our Team, coupled with the Aeroseal technology, gives us the ability to accurately measure and seal air duct leaks. We follow 6 steps to ensure savings, safety, and comfort:

  • Cover any designed opening in the system
  • Inject the sealant
  • Circulate particulate through the air ducts
  • Particle conglomeration occurs in leakage locations
  • Reseal air duct access locations
  • Flush excess particulate

Our Team then provides a comprehensive report summarizing the amount of leakage and verifying the success of the Aeroseal process.
