See moisture or spots? Mold kit vs a licensed assessor

There is no federal mold license and no EPA numeric “safe” mold count for homes. Moisture control is the actual control. This page summarizes EPA and the four state programs that license mold work. It is not medical, legal, or real-estate advice.

A kit is not a clearance

A consumer kit collects one tape-lift, swab, bulk piece, or settling dish and mails it to a lab — or grows colonies on a dish at home. That result describes that sample. It does not map hidden growth, find the water source, write a remediation plan, or certify that a cleanup is finished.

Post-remediation clearance (sometimes called a post-remediation assessment) is a separate inspection after the work, usually by an assessor who did not do the cleanup. A kit you run yourself is not that inspection. New York Labor Law Article 32 requires an independent licensed assessment to define the scope, and it forbids the same licensee from performing both assessment and remediation on the same project.

EPA’s homeowner guide: if the moldy area is less than about 10 square feet (roughly 3 ft by 3 ft), most people can clean hard surfaces themselves after they fix the water problem. Larger areas, HVAC contamination, sewage, or people who are sensitive to mold are reasons to hire. Source: A Brief Guide to Mold, Moisture and Your Home.

Assessor vs remediator (four states only)

Only Florida, Texas, New York, and Louisiana run a state mold license. This index does not invent a national credential.

Florida (DBPR). Individuals: mold assessor (MRSA) vs mold remediator (MRSR). The department does not license mold businesses. 2,991 current/active assessors and 2,882 current/active remediators on the weekly extract retrieved 2026-09-01.
Texas (TDLR). Companies and individuals. This index transcribed the company extracts: 204 current mold assessment companies and 465 current mold remediation companies. Confirm any individual consultant or technician on TDLR’s license search.
New York (DOL). Contractor licenses for assessment (SH125) and remediation (SH126), plus separate individual licenses. 794 active assessment contractors and 934 active remediation contractors on the Open Data four-year window. The same licensee must not assess and remediate the same project.
Louisiana (LSLBC). A mold remediation license certificate. The public lookup is a JavaScript search. This site does not invent a roster. verify on LSLBC.

Hire an assessor when you need to know whether there is a mold condition, where the moisture is, and what the scope of work should be — including after a cleanup. Hire a remediator to do the work in the plan. Do not let one company write its own clearance in a state that splits those jobs.

When a kit can be a first look

You see a small spot, you can dry the source, and you want a lab to name what is on that surface.
You are not in a real-estate, insurance, or landlord dispute that will demand a licensed report.
You understand a “present” result is common (mold spores are everywhere) and a “not detected on this tape” result is not a whole-house all-clear.

When to hire a licensed assessor

The area is larger than about 10 square feet, or mold is in the HVAC system, or the water was sewage or floodwater.
You are buying, selling, or documenting a rental, and someone will ask for a licensed report.
You need a written remediation plan or a post-remediation assessment.
Someone in the household is an infant, elderly, pregnant, or has asthma, allergies, or a weakened immune system — and you want a professional judgment, not a dish.
A kit result is positive, confusing, or was collected from the wrong surface.

This index lists Florida licensed mold assessors, Texas mold assessment companies, and New York licensed mold contractors. Louisiana: verify on LSLBC. Everywhere else, there may be no state mold license; do not treat a private trade-group logo as one.

If you buy a consumer kit

Both products below are mail-in sample kits analyzed at Schneider Laboratories Global. Lab fees are included. They are not a licensed mold assessment, not air testing of a whole house, and not post-remediation clearance. The mold-only kit is a surface tape-lift (not air). The combo kit adds one asbestos sample and one lead sample; those extra tests are not a mold clearance either.

What this site does not do

Mold Assessor Index does not rank contractors, take referral fees, or sell inspections. Amazon Associates links appear only on this how-to page. There is no live-call page, no tracking phone numbers, and no click-to-call. Always verify a professional’s license with the issuing agency.
