Our goal is simple:

To deliver cleaner air, lower bills, and consistent temperatures throughout your home.

Bringing Advanced Duct Sealing Technology to Your Home

Duct Sealing GTA was founded to help homeowners across the GTA achieve true comfort and efficiency.

As a certified Aeroseal partner, we offer solutions that traditional methods can’t — by sealing your ducts from the inside out using patented Aeroseal technology.

Why Choose Aeroseal Duct Sealing?

No tearing down walls — just measurable, lasting results.

Traditional duct tape and mastic only fix what you can see. Hidden cracks behind walls, floors, and ceilings leak up to 30–40 % of your heated or cooled air, driving up bills and reducing comfort.

Our Aeroseal duct sealing process seals those invisible leaks using a safe, aerosolized mist that precisely finds and fixes every gap.

  • Reduce energy waste by up to 30%
  • Enjoy consistent comfort year-round
  • Improve indoor air quality
  • Balance air flow and fix drafty rooms
