Aeroseal in Gatineau and Ottawa: Revolutionary duct sealing

Since 1992, Prop-Air has been committed to optimizing the comfort and health of your environments. Today, we’re taking your energy efficiency to new heights with Aeroseal technology. Did you know that in most buildings, up to 40% of heated or cooled air escapes through leaks in ventilation ducts? Whether you’re looking to reduce your energy bills in Gatineau or stabilize the temperature in your Ottawa offices, Aeroseal is the sealing solution par excellence. This patented process seals leaks from the inside, ensuring that air finally gets to where you really need it.

What is Aeroseal technology?

Aeroseal is an automated process that injects suspended adhesive particles into your ductwork. Under pressure, these particles attach themselves precisely to holes and cracks, sealing them permanently. Unlike manual methods, Aeroseal reaches invisible sections behind walls and between ceilings, making your ventilation ducts virtually watertight without any demolition work.

Tangible benefits for your energy efficiency

Choosing Aeroseal Canada with Prop-Air means choosing measurable, long-lasting performance for your building or home.

Massive energy savings

By eliminating leaks, your heating and air-conditioning system works less hard to reach the desired temperature. The result: a direct and significant reduction in your monthly electricity and gas bills.

Unrivalled thermal comfort

No more rooms that are too cold in winter or too hot in summer. Aeroseal ensures uniform air distribution in all areas of your building, eliminating temperature differences between floors.

Air quality and cleanliness

Sealed ducts prevent the infiltration of dust, pollutants and radon from wall cavities or crawl spaces. Your air stays cleaner and your surfaces stay cleaner longer.

Our 3-step sealing process

An Aeroseal intervention is fast, clean and accompanied by an official performance certificate.

1. Initial leak test

We block all your vents and pressurize the system. Our software accurately calculates the current leakage percentage of your ductwork before any intervention.

2. Automated injection and sealing

We inject Aeroseal mist into the ducts. You can follow the progressive sealing of leaks on our screen in real time. The process stops automatically once optimum sealing has been achieved.

3. Certification of results

Once the work is complete, we carry out a final verification test. You receive an official certificate documenting the exact reduction in leakage (often in excess of 90%), which is invaluable to the value of your property.

What our industrial customers say about us

Thoroughness has been at the heart of every one of our interventions for over 30 years in the National Capital Region.

FAQ on Aeroseal technology and sealing

Yes, that’s right. The adhesive used is non-toxic and ULC-certified for safe use in sensitive environments. In fact, it’s frequently used in hospitals, clinics and schools, as it has no lingering odors and contains no harmful volatile organic compounds (VOCs).

For an average home, the whole process (preparation, sealing and final testing) usually takes between 2 and 5 hours. Once the work is complete, you can resume your normal activities, with no additional clean-up required on your part.

The seal is guaranteed for 10 years in residential applications, but laboratory durability tests show that it remains effective, flexible and strong for over 40 years, even with the constant vibrations of the ventilation system.

Only accessible joints can be sealed with duct tape or hand mastic. Aeroseal works from the inside out, treating the entire network, including leaks hidden behind drywall or under floors, where human intervention is impossible without demolition.
