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.
