Wisconsin Mold Remediation Licensing & Laws

Does Wisconsin require a state license to do mold remediation?

No, Wisconsin does not have a mold-specific state license. Mold remediation work in Wisconsin is performed by contractors operating under Wisconsin’s general contractor licensing system. Verify any contractor’s license at the Wisconsin Department of Safety and Professional Services (DSPS, Dwelling Contractor) before signing a contract.

Who regulates mold work in Wisconsin?

In Wisconsin, mold work is governed by the contractor licensing rules of the Wisconsin Department of Safety and Professional Services (DSPS, Dwelling Contractor). Because there is no mold-specific state license, the practical questions when hiring are: does this contractor hold a current Wisconsin license that covers the work, do they carry insurance, and do they use a written contract with a clear scope. For tenant-side issues, the Wisconsin Attorney General consumer pages and your local code enforcement department are the right places to start.

How do I verify a Wisconsin contractor’s license?

Use the Wisconsin Department of Safety and Professional Services (DSPS, Dwelling Contractor) license verification or contractor search. Confirm the contractor is current, in the right classification for the work, and has no open disciplinary actions. Ask for proof of general liability insurance and (if the contractor has employees) workers’ compensation coverage.

What rights do Wisconsin tenants have when there is mold in a rental?

Most US states give residential tenants a statutory or common-law warranty of habitability. The exact mechanics in Wisconsin, including notice requirements, repair-and-deduct procedures, and termination remedies, are governed by state-specific statutes. The starting point is your state’s residential landlord-tenant law and, in some states, your local housing or health code.

This page is a state-level overview. Tenants in active disputes should not act unilaterally. Read the current statutes, talk to a Wisconsin attorney or a local legal aid organization, and document conditions in writing before withholding rent, vacating, or terminating a lease. The Wisconsin Attorney General consumer pages are a good starting point for state-specific guidance.

How do I file a complaint against a Wisconsin mold contractor?

Complaints about a Wisconsin licensed contractor go to the Wisconsin Department of Safety and Professional Services (DSPS, Dwelling Contractor). For tenant-side mold problems with a landlord rather than a contractor, the right channel is generally local code enforcement or the local health department, plus the Wisconsin Attorney General consumer protection division.
