Mold Remediation & Removal Companies in Minnesota

If you have found mold in your home or business, or an inspection has confirmed a problem, the next step is finding a qualified company to remove it. Below we introduce our directory of independent mold remediation and removal companies serving Minnesota. Mold Inspection & Testing (MI&T) is an inspection-and-testing-only firm, so we offer this directory as a courtesy to help you connect with contractors who do the physical remediation work.

Find a mold remediation company near you

Browse remediation companies serving communities throughout Minnesota, from the Twin Cities metro to Greater Minnesota.

Because MI&T performs independent inspection and testing only, we do not remediate. Scheduling your assessment separately from the company that performs the removal keeps your testing and clearance results objective.

We built this resource to make an unwelcome situation a little easier to navigate. The remediation companies listed here are independent businesses, not MI&T. We do not receive the removal work ourselves, and we are not a party to any agreement you reach with a contractor. Our role is to inspect, test, and document conditions so you can make an informed decision, and then, if you choose, to verify that the work was done.

Why mold is a common problem in Minnesota homes

Minnesota sits in a cold, humid continental climate where the same location that pulls in bitterly cold Arctic air in winter also draws warm, humid air from the Gulf of Mexico in summer. That combination gives indoor moisture many pathways. Annual precipitation ranges from about 23 inches in the far northwest to more than 35 inches in the southeast, and the state's long-term average is roughly 26 inches, according to the NOAA National Centers for Environmental Information State Climate Summary for Minnesota.

Water arrives in bulk, too. Most of the state averages 30 to 70 inches of snow a year, with totals near 90 inches along the shores of Lake Superior. When that snow melts in spring, or when the Red River of the North rises in the Red River Valley, low-lying basements and crawl spaces are among the first places moisture collects. With thousands of lakes across the state, high water tables and damp foundations are a familiar story for Minnesota homeowners.

The trend is toward more intense rainfall. NOAA reports that since 2000, very heavy rains of six inches or more in a single day have occurred two to three times more often than during the 20th century. Sudden heavy rain overwhelms drainage, backs up around foundations, and leaves behind exactly the damp, undisturbed conditions where mold thrives. A leak, a flooded basement, or elevated indoor humidity that is not dried quickly can lead to growth within a day or two.

Is mold remediation regulated in Minnesota?

Here is the key point for Minnesota residents: as of August 2026, Minnesota does not license or register mold remediation contractors or mold assessors specifically. There is no state-issued mold license or mold certification requirement. The Minnesota Department of Labor and Industry (DLI) licenses residential building contractors and remodelers by trade skill, such as carpentry, roofing, or drywall, but that general licensing framework does not include a mold-specific credential.

Because there is no state mold license to rely on, the burden of vetting a remediator falls to you. That makes voluntary industry certification, adequate liability insurance, and independent testing more important, not less. Look for training and certification through recognized bodies, ask for proof of insurance, and use an independent inspection and test to define the scope of work before removal begins and to verify results after. Confirm current requirements directly with DLI, since regulations can change.

Mold, renters, and landlords in Minnesota

Minnesota gives renters a notably strong statutory foundation. Under Minn. Stat. 504B.161, every residential lease includes covenants that the landlord will keep the premises and common areas fit for their intended use, in reasonable repair, and in compliance with applicable health and safety codes. These covenants apply to leases entered or renewed after June 15, 1971, and they cannot be waived or modified by the lease. While the statute does not single out mold by name, a mold problem tied to a moisture defect can fall within these habitability duties.

If a landlord does not address a covered condition, Minnesota provides a formal remedy. Under Minn. Stat. 504B.385, a tenant may file a rent-escrow action and deposit rent with the court administrator rather than paying it to the landlord, prompting a court hearing, typically within about 10 to 14 days. The court can order rent abatement, direct escrowed funds toward repairs, or require future deposits until the problem is fixed. Tenants generally cannot simply withhold rent outside this process. An independent inspection and test can help document conditions for either party. This is general information, not legal advice; consult an attorney about your situation.

Standards a good remediator follows

Because Minnesota sets no mold-specific licensing bar, professional standards do the heavy lifting. A competent remediation company generally works to the ANSI/IICRC S520 Standard for Professional Mold Remediation, which covers assessment, containment, safe removal, and the critical step of correcting the moisture source so mold does not return. Reputable contractors also follow the EPA's guidance on mold cleanup and moisture control. When samples are collected, they should be analyzed by an accredited laboratory, such as one participating in AIHA laboratory accreditation programs. Ask a prospective remediator how they establish containment, verify drying, and confirm the work with post-remediation testing.

How to choose a mold remediation contractor in Minnesota

Start with an independent inspection and test

Define the problem before you buy the solution. An independent assessment establishes the type and extent of the issue and gives you a written baseline. You can schedule an inspection with us at https://moldinspectionandtest.com/minnesota.

Confirm certification and insurance

Since there is no state mold license, ask for voluntary certifications, proof of general liability insurance, and references from recent Minnesota jobs. Confirm the company follows IICRC S520 and EPA guidance.

Get a written scope and clear pricing

A trustworthy contractor provides a detailed written scope that addresses the moisture source, containment, removal, and cleanup, with pricing you can compare against other bids.

Insist on post-remediation verification

Arrange for independent post-remediation testing so a party without a stake in the removal confirms the work succeeded. Keeping testing separate from remediation protects the objectivity of your clearance.

Frequently asked questions

• How do I find a mold remediation company near me in Minnesota?

  Use the directory on this page to browse independent mold remediation companies serving communities across Minnesota, from the Twin Cities metro to Duluth, Rochester, St. Cloud, and the Red River Valley. Mold Inspection & Testing provides independent inspection and testing only; we do not perform remediation, so the assessment we provide stays objective and separate from any company that does the work.

• Does Minnesota require a license to perform mold remediation?

  As of August 2026, Minnesota does not issue a state license specifically for mold remediation or mold assessment. The Minnesota Department of Labor and Industry licenses residential building contractors and remodelers by trade skill, but there is no mold-specific credential. Because the bar is set by voluntary industry certification rather than a mold license, it is worth confirming a contractor's training, insurance, and references.

• Why is mold so common in Minnesota homes?

  Minnesota's humid continental climate pairs cold, snowy winters with warm, humid summers, and the state has seen very heavy rains of six inches or more in a day occur two to three times more often since 2000 than in the 20th century. Spring snowmelt, Red River Valley flooding, thousands of lakes, and damp basements all give moisture a way indoors, where it can feed mold growth.

• What are a Minnesota renter's rights if there is mold in the unit?

  Under Minn. Stat. 504B.161, every residential lease in Minnesota carries covenants that the premises are fit for their intended use, kept in reasonable repair, and maintained in compliance with health and safety codes. These covenants cannot be waived. If conditions are not addressed, Minn. Stat. 504B.385 lets a tenant file a rent-escrow action and deposit rent with the court rather than the landlord. This is general information, not legal advice.

• What standards should a good mold remediation company follow?

  Reputable remediators work to the ANSI/IICRC S520 Standard for Professional Mold Remediation, follow EPA guidance on mold cleanup and moisture control, and send samples to accredited laboratories, such as those participating in AIHA laboratory accreditation programs. Ask whether a contractor documents containment, moisture correction, and post-remediation verification.

• Should mold inspection and mold remediation be done by the same company?

  Keeping them separate avoids a conflict of interest. When the company that inspects and tests is not the company that performs the removal, the findings and the post-remediation clearance test are not influenced by an incentive to sell more work. Mold Inspection & Testing is inspection-and-testing-only for exactly this reason, and the remediation companies in our directory are independent.
