Flint particulars
Flint's sewer page counts what the city looks after: about 600 miles of sanitary sewers, 350 miles of storm sewers and 600 miles of water mains. It says the Water Service Center phones are answered 24 hours a day, and the emergency contact for the sewer and storm sewer group is (810) 766-7079, monitored around the clock, though the page does not word it as a sewer backup line. Water Pollution Control, the wastewater treatment facility, is at 810-766-7210.
Flint has 80,835 residents, 93.2 percent of its homes were built before 1980 and the median home is worth $47,600, the lowest among the 30 largest cities. Ask your insurer how it values the house and what the repair scope is before you authorize tear-out. Genesee County was not among the counties named in the four federal disaster declarations since 2021. Permits come from Building and Safety Inspections at 1101 S.

Mold remediation in Flint: what to know
EPA says older buildings may have materials containing asbestos or lead. There is no Michigan certification for a mold remediation firm to show you. MDHHS describes the reasons to clean mold up: headaches, runny eyes and noses, coughing, and complications for children and adults with asthma. Building and Safety Inspections, 810-766-7284, handles rebuilding permits.
At a median home value of $47,600, ask your insurer about valuation before a large rebuild.
With so many older homes, ask if the company will test or assume that old materials contain lead or asbestos, and what that does to the price. EPA says older buildings may contain either.
Permits for mold remediation in Flint
MDHHS says the state does not certify remediators.
Many cities run their own building department, so start by asking the City of Flint building department who issues restoration permits.
When mold cannot wait
- Mold followed sewage or floodwater.
- Growth covers a large area or has returned after cleaning.
- Someone with asthma, a lung condition or a weak immune system lives in the house.
- A small patch of visible mold under about 10 square feet on a hard surface, once the moisture is fixed.
- A musty smell with no visible growth and no active leak, which you can raise with your insurer first.
The first hour with mold
Try this first: photograph the growth and ask how the crew will handle old materials.
- Stop the moisture. A leak, a damp wall or standing water feeds mold, and cleaning without fixing it only resets the clock.
- Stay out of areas with visible or smelled mold if you have asthma, a lung condition or a suppressed immune system. MiReady says those people should not enter buildings with visible or smelled mold.
- Photograph the growth and the damp areas, and write down when the water event happened. Your insurer will ask.
- Measure the patch if you can. EPA says that under about 10 square feet, roughly 3 feet by 3 feet, most people can handle it; over that, or after a lot of water damage, read EPA's remediation guidance.
- Do not pay for a test first. MDHHS says it cannot test your home and does not recommend mold testing; its hotline is 800-648-6942.
- If the area is large, the water was sewage, or you cannot find the moisture source, request a company on the form.
What mold remediation costs
The estimate below is the Michigan-wide one, adjusted for Michigan wages and not for Flint in particular. The same table is on the mold remediation page. How we estimate costs. Prices as of Oct 19, 2026.
| Item | Figure | What it is |
|---|---|---|
| Estimated range, not a quote | $1,400 to $5,625 per job | Built from 3 national published ranges, adjusted by the Michigan hazardous materials removal worker median wage ratio (0.94). No Michigan restoration company price is shown, because none of the companies we looked at published a price we could count. |
| Estimated range per square foot, not a quote | $12 to $32 per square foot | Built from one national published range, adjusted by the Michigan hazardous materials removal worker median wage ratio (0.94). No Michigan restoration company price is shown, because none of the companies we looked at published a price we could count. |
| Hazardous materials removal worker wage, Michigan median | $22.30 an hour (middle half of workers: $19.66 to $26.65) | What the nearest federal occupation is paid (BLS May 2025, read through O*NET OnLine), not what you are charged. BLS has no water or fire restoration occupation. |
| Same occupation, Detroit-Warren-Dearborn median | $22.30 an hour (middle half: $19.83 to $27.17) | Pay, not price. Mapping to restoration crews is our inference. |
| Same occupation, Grand Rapids-Wyoming-Kentwood median | $21.82 an hour (middle half: $19.66 to $27.50) | Pay, not price. |
How we estimate costs: the Estimated range row is a model, not a quote. It takes 3 published national ranges for this job (cost guides from third-party sites that we have not verified and do not cite) and multiplies them by Michigan's hazardous materials removal worker median wage ratio to the US (0.94, BLS May 2025 data read through O*NET OnLine), the nearest federal occupation to a restoration crew. The wage rows in the table are what that occupation is paid, which is not a price. Restoration is priced from measured damage and equipment and is often paid by an insurer, so a real quote can land outside the range. We have not collected quotes, and we found no Michigan restoration company that publishes a price we could count. Full method.
Questions about mold remediation
Does Michigan require a license to remediate mold?
The State of Michigan does not provide certification for mold remediators or mold testing companies, MDHHS says. That covers certification only, and we can cite no state mold license page. Rebuilding work can still need the builder license.
Can I remediate mold myself?
For under about 10 square feet, roughly 3 feet by 3 feet, EPA says most people can handle it. For larger areas or after a lot of water damage, EPA points to its remediation guide. People with asthma or weak immunity should not do the cleanup.
Should I pay for a mold test in Michigan?
MDHHS does not recommend testing and cannot test your home, and EPA says sampling is unnecessary if mold is visible. Spend the effort on finding the moisture.
