Our process

Four steps to a detailed, defensible report.

  1. 1
    Consultation

    We listen to your concern — visible mold, musty odor, recent leak, or a real estate deadline — and scope the inspection.

  2. 2
    On-site Inspection

    Full visual assessment, moisture mapping, thermal imaging, and, when needed, wall cavity or HVAC evaluation.

  3. 3
    Laboratory Testing

    Air and surface samples are analyzed by an independent, accredited laboratory — never by us.

  4. 4
    Detailed Report

    Photographs, moisture readings, lab data, and clear next steps delivered within 2–3 business days.
