Mold Armor DIY Mold Test Kit

Mold Remediation · $1,500–$6,000 for a professional service

Check price →

A budget surface-and-air screening kit that tells you whether mold is present, useful as a first signal after a leak. Be realistic about its limits: a DIY kit confirms presence, not species or concentration, and it cannot replace an IICRC-certified assessor for anything beyond a small visible patch. We recommend it only as a triage step — if it is positive, or the affected area is over ~10 square feet, move to a professional assessment and an IICRC S520 remediation protocol.

When a kit isn’t enough: a DIY kit is a screening tool. For mold remediation, confirm any concerning result with a IICRC-aligned professional or certified lab before acting.
