HIGH-RESOLUTION INFRARED THERMOGRAPHY • 4K VISIBLE PHOTO vs. FLIR THERMAL IMAGING

Hidden water leaks behind painted walls create evaporative cooling patterns (ΔT) long before stains appear on the surface. Drag the interactive slider below to see how our calibrated FLIR thermal cameras pinpoint hidden moisture non-invasively.

Surface is within 3.0°F of the dew point. Relative humidity in the surface boundary layer exceeds 80%, creating an active incubation zone for Aspergillus and Penicillium without bulk liquid water.
TEXAS OCCUPATIONS CODE CH. 1958

Our Zero-Conflict Guarantee: Honest Answers Without a Sales Pitch

16 TAC § 78.70 • TOC § 1958.155 • 100% UNBIASED DIAGNOSTICS • CONSUMER PROTECTION

Texas law strictly separates mold inspection from mold remediation to protect homeowners and commercial buyers from predatory conflicts of interest. Under Texas Occupations Code § 1958.155, a licensed Mold Assessment Consultant (MAC) who inspects your property is legally prohibited from selling you the remediation cleanup on that same building for regulated projects (≥ 25 contiguous sq ft).

TEXAS STATUTORY CONSUMER PROTECTION

Why Our Consulting Division Never Upsells Unnecessary Remediation

Many unregulated contractors advertise "free mold inspections" only to invent expensive, unnecessary demolition estimates. When you hire Envirogyn's Consulting Division (TDLR MAC #1544), our sole responsibility is to give you objective scientific facts, map moisture accurately, test your air at our accredited laboratory, and write a precise scope of work so no contractor can overcharge you.

OFFICIAL STATE CLEARANCE TESTING

Post-Remediation Verification (PRV) & Certificate MDR-1

HEALTHY AIR VERIFICATION • TDI FORM MDR-1 ISSUANCE • INSURANCE & REAL ESTATE PROTECTION

Before your contractor takes down their plastic containment or rebuilds your drywall, Texas law requires an independent Mold Assessment Consultant to verify that the area is completely clean, dry, and safe to breathe. Passing clearance allows us to issue your official Texas Certificate of Mold Damage Remediation (Form MDR-1).

Independent Post-Remediation Verification moisture and air clearance check
STEP 01 • ON-SITE CLEARANCE AUDIT

Independent PRV Clearance Inspection

Thorough visual inspection, moisture verification, and air quality clearance testing inside the containment zone before barriers are removed.
