From the shaded courtyards of Alamo Heights to the historic stone homes of King William, our mission is to safeguard the indoor air quality of every San Antonio residence. With deep local knowledge, we know where mold hides—whether it’s in aging HVAC systems of Mission-style homes, beneath tile in Southtown remodels, or behind walls in high-rise condos near the River Walk. Our inspections combine visual expertise, precision moisture detection, certified air sampling, and accredited lab analysis to deliver fast, accurate, and unbiased mold reports you can rely on.

Inspections Only – Not Remediation
Unlike cheaper companies with a conflict of interest, our partners provide unbiased assessments because they don't profit from finding problems. Our only job is to make sure you get the truth, not buy services you don't need.
Texas Occupations Code 1958.155(a) prohibits licensed mold inspectors from both inspecting and cleaning/remediating. We follow this ethical standard nationwide, even where not legally required.
