If you have found mold in your home or business, or a musty basement smell that will not go away, you are looking for a qualified company to remove it. Below you will find our courtesy directory of independent mold remediation and removal companies serving Michigan. At Mold Inspection & Testing (MI&T), we specialize in independent mold inspection and testing only — we do not perform remediation — so we offer this list purely as a resource to help Michigan property owners connect with reputable remediators and move forward with confidence.
Select your city or region below to see independent mold remediation companies that serve your area of Michigan, from the Lower Peninsula to the Upper Peninsula.
Before you hire, consider an independent inspection. Because we test but never remediate, an independent inspection and test from MI&T gives you an unbiased, documented scope of work you can hand to any remediator on this list — so bids are comparable and the work is verified when it is done.
This directory is provided as a free courtesy. The remediation companies listed are independent businesses and are not owned by, employed by, or affiliated with MI&T. We do not remediate mold ourselves; our role is limited to inspection, testing, and post-remediation verification. Listing a company is not an endorsement or a guarantee of its work, and we encourage you to do your own due diligence before signing any contract.
Michigan sits in a humid-continental climate that is defined by the Great Lakes. All that surrounding water feeds humid summers, heavy lake-effect snow, and abundant year-round moisture — ideal conditions for indoor mold whenever it finds its way inside. According to the NOAA Michigan State Climate Summary, statewide annual precipitation has ranged from as little as 22.7 inches in the drought year of 1930 to 41.8 inches in 2019, and the frequency of 2-inch extreme precipitation events during 2010–2020 was the highest on record. More water arriving in heavier bursts means more opportunities for it to reach basements, crawl spaces, and wall cavities.
Metro Detroit and other older urban areas add a distinct risk: flash flooding and sanitary-sewer backups. Southeast Michigan experienced major, widely reported flood events in August 2014 and again in June and July of 2021, sending water into thousands of basements. When storm water or sewage backs up into a finished basement, porous materials like drywall, carpet padding, and framing can begin growing mold within a day or two if they are not dried quickly and correctly.
Finally, much of Michigan's housing stock is old. Detroit, Flint, Grand Rapids, Lansing, and many smaller towns are full of homes built decades ago, often with below-grade basements, limited waterproofing, and aging plumbing. NOAA also notes that Lake Michigan–Huron water levels rose rapidly through the late 2010s to their highest point since record-keeping began in 1886, raising groundwater and seepage pressure on those older foundations. Combine humid summers, snowmelt, urban flooding, and older construction, and it is easy to see why mold is a recurring concern for Michigan property owners.
This surprises many homeowners: Michigan does not license or register mold remediation contractors or mold assessors. There is no mold-specific state credential, no state exam, and no state-mandated fee schedule for this trade. The Michigan Department of Health and Human Services publishes helpful consumer guidance on moisture and mold, but that guidance is advisory, not a licensing requirement. Separately, the Michigan Department of Licensing and Regulatory Affairs (LARA) licenses residential builders and maintenance-and-alteration contractors, but that is a general construction license — it is not a mold-remediation license and does not certify anyone's expertise in mold work.
Because the state sets no minimum bar, the burden of vetting falls on you. We suggest looking for voluntary industry credentials — most notably certification through the IICRC — along with current general-liability insurance, verifiable references, and a clear written scope of work. In a state with no license to fall back on, an independent inspection and test becomes even more valuable: it documents what actually needs to be done, so you are not relying on a contractor's word alone.
Michigan has no statute that specifically addresses mold in rental housing, and no mold-disclosure requirement. Instead, tenant protections come from general habitability law. Under MCL 554.139, every residential lease in Michigan includes a landlord covenant to keep the premises and common areas fit for the use intended by the parties and to keep the premises in reasonable repair and comply with applicable health and safety laws. These statutory covenants work alongside the implied warranty of habitability, and the Truth in Renting Act regulates what a lease may and may not say.
In practice, a serious moisture or mold problem that makes a unit unfit can fall within these duties. Michigan tenants generally must notify the landlord and allow a reasonable chance to repair; remedies such as repair-and-deduct or paying rent into court escrow typically run through the district courts rather than being taken unilaterally. If you are a renter documenting a mold concern, an independent inspection report and lab results create an objective record of conditions and dates that can support a conversation with your landlord. The above is general information about Michigan law, not legal advice; for your situation, consult a qualified attorney.
Since Michigan does not define what "good" remediation looks like, the industry's voluntary standards fill that gap. A reputable Michigan remediator should be able to explain how their work aligns with:
A remediator who fixes the moisture source, contains the work area, and supports post-remediation verification testing is following the spirit of these standards — and giving you a result you can trust.
Have the problem assessed by a company that only inspects and tests, not one that also sells removal. This separates diagnosis from the sales pitch and gives you a documented scope. You can schedule an independent Michigan inspection with us at https://moldinspectionandtest.com/michigan.
With no state license to check, confirm current general-liability insurance, IICRC or equivalent certification, and recent local references. Ask specifically about experience with Michigan basements and flood or sewer-backup cleanups.
Insist on a written scope of work naming affected materials, containment, and moisture correction. Share the same inspection report with two or three remediators so bids are truly comparable.
Once removal is complete, have an independent party perform post-remediation verification testing before you pay in full. Passing an independent clearance test is your proof the job was done right.
Browse the directory on this page to find independent mold remediation and removal companies serving communities across Michigan, from Detroit and Grand Rapids to Traverse City and the Upper Peninsula. We are an inspection-and-testing-only firm, so the remediation companies listed here are independent businesses. We suggest getting an independent inspection and test first, then sharing that documented scope with two or three remediators so you can compare bids on equal footing.
No. Michigan does not license or register mold remediators or mold assessors, and there is no mold-specific state credential. The Michigan Department of Health and Human Services offers guidance only. Because there is no state license, we recommend verifying voluntary certification (such as IICRC), current liability insurance, references, and a written scope of work before hiring.
Michigan's humid-continental climate, Great Lakes moisture, humid summers, and heavy lake-effect snowmelt keep indoor humidity high. Annual precipitation has trended upward, reaching 41.8 inches statewide in 2019, and the state's older housing stock with damp basements is prone to seepage. Urban flooding and sewer backups, like the major Metro Detroit floods of 2014 and 2021, are a frequent trigger for basement mold.
Michigan has no mold-specific landlord statute, but under MCL 554.139 a landlord covenants to keep residential premises fit for the intended use and in reasonable repair and to comply with applicable health and safety laws. This works alongside the implied warranty of habitability and the Truth in Renting Act. Tenants generally must give notice, and remedies such as repair-and-deduct or rent escrow typically involve the courts. This is general information, not legal advice.
Look for a remediator who works to the ANSI/IICRC S520 Standard for Professional Mold Remediation, follows U.S. EPA mold guidance, and uses independent laboratories accredited through the AIHA Laboratory Accreditation Programs for sample analysis. These voluntary standards matter especially in Michigan, where no state license sets a minimum bar.
We think it helps. An independent inspection and test from a testing-only firm like ours identifies the moisture source and defines the scope before any removal begins, and because we do not perform remediation there is no incentive to over-scope the work. You can then compare remediation bids objectively and confirm the job with post-remediation verification testing.
