Eastern Ontario’s # 1 home sealing organization

Airtight Home Technologies

Providing AeroBarrier Sealing to New Homes & Major Renovations in Eastern Ontario


An airtight house is a comfortable house. Imagine if you had a window in your house that could not be closed. That’s what air leakage is. It creates drafts and cold spots in your home and reduces your comfort.

Energy Savings

As much as 50% of the energy required to heat and cool your house is due to uncontrolled air leakage through your walls, ceilings, and exposed floors. Make your house tight and save money on your heating and cooling bills.


When air leaks into your building envelope it carries with it moisture. Mould can form especially during the winter. Making your building airtight makes your building more durable, and that protects your investment.

Our Process

Set Up

Equipment is set up at the job site. Conveniently transported by trailer, AeroBarrier install equipment is mobile and portable. The equipment includes a compressor, generator, blower door, sprayers, hoses, and the AeroBarrier machine.


Prep the space. This includes taping or covering any areas that won’t be sealed. Sprayers are then set up throughout the area to be sealed.


Pressurize the space with the use of a blower door. A computer does the rest, including the control of temperature, pressure, humidity, and distribution of sealant during the process.


See the results in real-time. Throughout the application process, the computer monitor displays the ACH improvement, allowing you full control over your desired level of envelope tightness and leakage reduction.


Run a final blower door test to verify the sealing results. At the end of the process, receive an AeroBarrier Certificate, with a pre and post leakage report.
