Mold Testing Services in Maryland Heights, MO

Maryland Heights ranches have a moisture source most homeowners never think about: the HVAC system itself. Homes from the 70s and 80s run original or second-generation ductwork, and air conditioning condensate, undersized returns, and aging drain lines create moisture right inside the system that distributes air to every room.

A typical Maryland Heights job: a homeowner smells mustiness only when the AC kicks on, strongest in summer. That pattern points at the system, not the structure. Our inspection found a condensate drain backing up into the plenum and visible growth at the coil housing, with air samples confirming the system was distributing spores house-wide every cooling cycle. The fix was a defined HVAC cleaning and remediation plus the drain repair, and the retest confirmed clean air at the registers.

Our inspection covers the structure and the system: moisture readings throughout, a look at HVAC moisture points, air samples compared against an outdoor baseline, and surface sampling wherever growth appears. Accredited lab analysis, written report, plain language.

Call us for odors that track with heating or cooling cycles, slab-level moisture and flooring issues common in ranches, musty basements and utility rooms, symptoms that flare at home, pre-purchase testing, and post-remediation clearance.

We're NORMI certified assessors, and if your air comes back normal, the report says normal and you're done.
