Blower-door testing.

For ratings & certifications

EnerGuide, ENERGY STAR and Net Zero all require a measured air-change rate. We run the test to the current standard and fold the result straight into the modelling and documentation.

Stand-alone diagnostics

Draughty rooms, uneven temperatures, ice damming or high bills often trace back to specific leaks. Paired with smoke or thermal imaging, a blower-door test locates them so you fix the right things.

Construction-stage testing

For new builds and deep retrofits, a mid-construction test while walls are still open lets the crew seal problems before drywall, far cheaper than chasing them later.
