Mold Testing Services in Clayton, MO

Clayton's air quality questions come from every direction: pre-war homes with old masonry, mid-century condo buildings running shared HVAC, and office space where an odor complaint involves a property manager, a tenant, and sometimes a lease dispute. What they share is the need for independent, documented answers.

A representative Clayton job: a condo owner reports a persistent musty smell the building engineer can't locate. Shared walls and shared air handling make condo mold genuinely tricky, because the source can be someone else's unit or the building's own systems. Our testing established elevated levels in the unit, sampling narrowed the source to a chase wall carrying a slow leak from above, and the lab documentation gave the owner what they needed for the building's insurance process. Without independent testing, that stays an argument; with it, it became a claim.

Our inspection covers residential and commercial: moisture readings, air samples compared against an outdoor baseline, surface sampling, HVAC considerations in shared systems, and source identification. Accredited lab analysis with reports formatted for property managers, insurers, and attorneys when needed.

Call us for condo and apartment air quality disputes, office tenant complaints, pre-purchase testing on homes and units, musty odors in older Clayton homes, and post-remediation clearance verification.

We're NORMI certified mold assessors, and independence is our entire value in situations like these: our results hold up because we have no stake in what they say.
