Mold Remediation & Assessment
Mold inspection, testing and remediation — with state licence status verified where licensing exists.
Mold remediation is the only restoration trade that some states license. Five US jurisdictions — Texas, Florida, New York, Louisiana and the District of Columbia — run mold licensing programs; everywhere else, IICRC certification is the primary credential a consumer can check.

What mold remediation services actually include
A complete scope covers five things: containing the affected area so the work does not spread contamination, physically removing the growth and the materials supporting it, cleaning the settled spores in adjoining areas, correcting the moisture source that caused it, and verifying the result. A quote missing the moisture step is not a complete scope — under IICRC S520 the growth returns because the condition that produced it was never addressed. What the process involves →
What makes a mold remediation specialist different from a general contractor
The credential. AMRT — Applied Microbial Remediation Technician — is the core IICRC certification for this work, with AMRS and MRS as rarer advanced designations. A general contractor may do excellent work and hold none of them; a firm advertising mould expertise while holding only cleaning credentials is a different proposition again. Every profile here decodes exactly which certifications are on record with the issuing body.
Signs of mold in a house, and what they are worth
The evidence that matters most is the evidence you can see and smell: visible growth, a persistent musty odour, staining or bubbling on walls and ceilings, and a known water history — a leak, a flood, a slow seep, condensation. IICRC S520 treats visual inspection, moisture verification and surface assessment as carrying more weight than air sampling, and EPA does not recommend routine sampling for most situations and states there are no federal limits for mould or mould spores — so there is no threshold a lab number could be measured against. If you can see it or smell it, you already have the finding that counts. Why testing is the weakest tool →
Mold inspection and mold remediation are different jobs
An inspection or assessment establishes what is there and writes the protocol; remediation carries it out. Four of the five US jurisdictions that license mould work require those roles to be held by different parties, and where no licence exists it is still worth insisting on — a contractor who writes their own scope of work decides how much work they will be paid for.
Mold Remediation: the questions worth asking
What is the difference between mold removal and mold remediation?
Mold removal implies eliminating mold, which is not achievable — mold spores are present in all indoor air. Remediation means returning the affected area to a normal fungal ecology: fixing the moisture source, containing the work area, removing contaminated materials and verifying the result. IICRC S520 is the governing standard, and it uses the word remediation for exactly this reason.
Does my state license mold remediation?
Five US jurisdictions license mold assessment and remediation. Illinois has enacted a registration law that is not yet in force. The rest have no mold-specific licence, though general contractor and business registration may still apply. Our state-by-state chart shows each jurisdiction with the statute it comes from and the date we checked it.
Can my mold inspector also do the remediation?
In every jurisdiction that licenses mold work, no — the assessor writes the protocol and an independent remediator carries it out. In the other states nothing stops a single firm doing both, which is precisely why it is worth insisting on the separation: a contractor who writes their own scope of work decides how much work they are going to be paid for.
Which certification should a mold remediation firm hold?
AMRT — Applied Microbial Remediation Technician — is the core credential. AMRS and MRS are rarer advanced designations. A firm advertising mold expertise while holding only cleaning credentials is a different proposition, and our profiles decode exactly which certifications a firm actually holds.
