How much does mold air testing cost?

A standalone visit with limited sampling in this area is typically $250–$450, depending on how many samples the question actually needs and whether the attic or crawl is accessible. Clearance sampling after remediation is often $150–$350. Lab fees should be understandable in the quote, not a surprise line.

More cassettes are not a better test. An outdoor control plus the rooms that matter beats a dozen samples with no moisture map.
