On-Site Lab and Mold Testing Services in Central Florida

With our on-site lab, sample results are available within hours, so you can act on findings the same day rather than waiting on a third-party turnaround.

Air samples measure airborne spore types and concentrations, and gets compared against an outdoor baseline — without that comparison, a raw spore count means very little. Swab samples from visible growth or suspect surfaces identify specific species. Pairing those with moisture mapping and detection tools uncovers mold behind walls, above ceilings, and in other concealed areas that a visual inspection alone will miss. Full coverage across our Tampa Bay and Gulf Coast service areas.

Home kits confirm that mold spores exist, which they will in essentially any building. They don't identify species, measure concentration, or compare against outdoor conditions — so they produce both false alarms and false confidence. A professional report gives you spore counts, species names, laboratory data, and expert opinion on health and structural risk. That's the difference between suspecting a problem and documenting one.

Yes. Mold assessors and remediators must hold a license through the Florida Department of Business and Professional Regulation. This matters beyond compliance: insurers and courts generally only accept reports from a licensed assessor. IET is led by licensed Florida mold assessor Matthew Fitzgerald, MRSA5590, who also serves as an expert witness. Verify credentials before hiring anyone, and confirm the assessor has no financial stake in the remediation work.

Warm coastal air, year-round humidity averaging around 74%, and a steady cycle of rain, storms, and flooding keep building materials damp. Mold consumes organic material — wood framing, drywall paper, insulation backing — so a problem left undetected turns into a structural repair cost, not just an air quality issue. Proactive testing catches it while it's still cheap to fix.

No. We test and report; for removal, we refer you to certified remediation professionals and provide clearance testing afterward to confirm the work succeeded. Guidance generally puts around 10 square feet as the threshold where professional cleanup is warranted rather than DIY. Whatever the size, fixing the moisture source — the leak, the ventilation failure, the humidity load — is what keeps mold from returning. Follow health and safety precautions during any cleanup, and keep monitoring afterward.

Several firms operate in the St. Petersburg market, including MSE Environmental and The Mold Girl, and any of them can collect a sample. What separates assessors is licensure, tenure, and whether they profit from what the report recommends. IET has tested buildings across Tampa Bay since 1992 under licensed Florida mold assessor Matthew Fitzgerald, MRSA5590, who also serves as an expert witness — and has never performed remediation.
