13 certified mold remediation firms in Louisville, KY
Ordered by verified credentials only — cross-verified firms first, then active state licences, then breadth of certification. Payment never affects this order.
Kentucky does not run a mold-specific licensing program. Only five US jurisdictions do (Texas, Florida, New York, Louisiana and the District of Columbia; Illinois has enacted a program that is not yet in force). In Kentucky, the credentials to check are IICRC certification, general contractor licensing where applicable, and insurance.
Can my mold inspector also do the remediation?
4 of the 5 licensing jurisdictions bar the same party from assessing and remediating the same property or project: Texas, Florida, New York and Louisiana. District of Columbia does not — the rule there is disclosure of conflicts and a bar on working where the licensee has a financial interest, not a prohibition on holding both roles. Where no mold licence exists, nothing stops one firm doing both — using an independent assessor is then your own protection against a contractor writing the scope of work they will be paid to perform.

Housing here
288,047 housing units in Louisville/Jefferson County metro government (balance), Kentucky, of which 62% were built before 1980 and 16% before 1940. 39% of occupied homes are rented.
Why this is on the page: older housing has had longer to accumulate water events, and its plumbing and building envelope are closer to end of life — so age is a reasonable proxy for how often local firms meet older construction, not a statement about any individual property. It does not mean older homes have mold. With 39% of homes rented, a large share of water and mold problems here are a landlord repair duty before they are a contractor decision.
