Air Leakage Testing (Blower Door) in Richmond, BC

Air leakage testing (blower door testing) measures the airtightness of a building envelope and identifies air leakage paths that also serve as water entry points. A calibrated fan is mounted in an exterior door opening and used to depressurize the building (drawing air outward) or pressurize it (forcing air inward). Using a combination of smoke pencils, thermal imaging during depressurization, and flow hood measurements, we identify the location and magnitude of air leakage paths. In BC's climate, where wind-driven rain is common, air leakage paths are significant water entry points — water is literally pushed through these openings by wind pressure during rain events. Blower door testing is essential for comprehensive building envelope investigations.
