Trusted Industrial Hygiene & Indoor Air Quality Experts Serving Calgary & Southern Alberta
Doctor IAQ Inc. is a Calgary‑based industrial hygiene and indoor air quality consulting firm with more than 30 years of hands‑on experience supporting businesses, property managers, restoration companies, and homeowners across Alberta. We specialize in delivering accurate, defensible, and practical environmental assessments that help our clients protect health, meet regulatory requirements, and make informed decisions.
Our background spans decades of exposure monitoring, IAQ investigations, chemical sampling, mould assessments, noise surveys, silica testing, and workplace hazard evaluations. That experience allows us to approach every project with the confidence, clarity, and technical precision our clients rely on.
Our Mission
To provide clear, science‑based assessments that improve indoor environments, protect worker health, and support safe, compliant workplaces—without unnecessary complexity or conflict of interest.
