Your first hour in a flooded basement
- Smell gas? Leave and call 911, then DTE at (800) 947-5000 or Consumers Energy at 800-477-5050. Never go back for anything.
- Do not go down the stairs if water covers outlets, the furnace or the panel. MiReady says not to touch electrical equipment that is wet or while standing in water, and underground power lines can charge floodwater.
- If the water came up a drain or toilet, treat it as sewage, because MDHHS says floodwater can carry bacteria and raw sewage. Run no water in the house, since every flush and every load of laundry sends more down the same pipe.
- Photograph the water line from the stairs before anything is pumped, then call your insurer and say you have water damage.
- Request a company on the form next. Run generators only outdoors, away from windows, and keep children out of the cleanup.
- If you have a private well, MDHHS says to test the well water after a flood; its hotline is 844-934-1315.
Clean water, sewage or flood: three different basements
Water from a failed supply line, water that seeped in through a wall, and water that rose through a floor drain are not the same job, and they are not the same insurance claim. The first is mitigation and drying. The last is Category 3 under the IICRC definition, which includes sewage and wasteline backflows, and it is covered on the sewage cleanup page.
Older homes carry another risk. EPA says older homes and buildings may have building materials that contain asbestos or lead, and to read its protecting-your-health pages before cleanup. EPA's lead rule for contractors has a narrow emergency provision, but a company that tears out painted surfaces in a pre-1978 house later still has to be certified under it.
What flooded basement cleanup costs in Michigan: estimates, not quotes
Our estimate for flooded basement cleanup in Michigan is $1,700 to $8,900 per job, or $3 to $13 per square foot. It is a model, not a quote. Two public figures show how large flood losses get, and neither is a price list: DIFS prints an illustration for a 1,000 square foot slab home, and our own count of NFIP claim records shows what insured Michigan flood claims have paid since 2021.
| Item | Figure | What it is |
|---|---|---|
| Estimated range, not a quote | $1,700 to $8,900 per job | Built from 2 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 | $3 to $13 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. |
| DIFS flood cost illustration, 1,000 sq ft slab home | $10,600 for 1 inch of water; $20,150 for 6 inches; $27,150 for 1 foot | DIFS marks this table illustrative only, not for estimating real losses. |
| NFIP claims paid in Michigan since 2021 | 780 of 1,105 claims paid; mean about $23,800, median about $10,900 | Our own calculation from OpenFEMA records, not a FEMA statement. Insured claims only. |
How we estimate costs: the Estimated range row is a model, not a quote. It takes 2 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. Prices as of Oct 19, 2026.
Which policy answers for a flooded basement
DIFS says flood damage is typically not covered unless you bought flood insurance, and that water and sewer backup is not automatically covered under a homeowners or renters policy. It also says you do not have to be in a flood zone to have a flood. The backup coverage is an endorsement: it pays for backup of water through a sewer or drain and for water that overflows from a sump, up to a selected limit, but typically not for flood, a broken sump pump or a pump worn out for lack of maintenance.
Flood coverage comes from the National Flood Insurance Program or a private insurer. The NFIP takes effect 30 days after purchase, with four listed exceptions, and its building cover goes to $250,000 with $100,000 for contents. Its basement coverage is limited, it does not cover mold, and it excludes temporary housing costs. The flood versus homeowners policy guide covers it in full.
When the city's sewer is involved
A sewage backup can be a government problem. Under MCL 691.1419 you must give the responsible agency written notice within 45 days after you discovered the damage, and the law does not treat a backup as a sewage disposal system event when a substantial cause was a blockage in a service lead the agency did not cause, or a connection on your property such as a sump system or building drain. Your city page lists the public works number where we found one, and the sewer backup guide explains the notice.
When a flooded basement cannot wait
- Water is above the outlets, the furnace or the panel.
- Water came up through a floor drain or toilet.
- Water is still rising.
- You smell gas or fuel.
- A damp floor with no standing water after a storm, once the source is clear. Photograph it and start drying.
- Seepage that has stopped and left the carpet wet but nothing electrical in it.
Basement flood repairs: which licenses and permits apply
Pumping out and drying are not licensed crafts in Michigan, and the maintenance and alteration license lists waterproofing a basement as a craft, so a company that waterproofs for pay on a one- or two-family home needs that license from $600 of work. Replacing a flooded furnace, water heater or electrical panel is trade work under its own license and usually a permit; your city page names the permit office.
Ask which licenses your state requires for the work, and check them with your state's licensing office before any work starts. A credential from a private body, such as IICRC, is not a license.
A tool for this job
Will insurance pay?
What insurance pays depends on the cause and on the policy in your drawer, and nobody here has read yours. This tool gives what the Michigan insurance regulator (DIFS) and the National Flood Insurance Program say for each common cause, and what to ask your agent. It is not a coverage decision.
Open the toolQuestions people ask
Who do I contact if my basement is flooded in Michigan?
Your insurer, a restoration company, and your city's public works if the water is sewage. Public works numbers are on the city pages where we found them, such as Dearborn and Ann Arbor. For a sewage backup, remember the 45-day written notice if you may claim against the city or county.
Does homeowners insurance pay for a flooded basement in Michigan?
Not automatically: DIFS says flood damage is typically not covered unless you bought flood insurance, and water and sewer backup is not automatically covered. Tell your insurer you have water damage, because rain intrusion, sewer backup or a failing sump pump may be covered.
How much does flooded basement cleanup cost in Michigan?
Our estimate is $1,700 to $8,900 per job, or $3 to $13 per square foot. It is a model, not a quote and not a Michigan company price. DIFS's illustration for a 1,000 square foot slab home runs from $10,600 for 1 inch of water to $27,150 for 1 foot, and DIFS marks it as not for estimating real losses. The widely repeated $25,000 per inch figure did not appear on any FEMA or DIFS page we read, so we do not use it.
Does flood insurance start right away?
No: NFIP coverage takes effect 30 days after purchase, with exceptions such as buying with a new or increased mortgage. FloodSmart lists them. MiReady says a policy typically takes up to 30 days to go into effect.
Is a flooded basement dangerous to clean up myself?
It can be. MiReady says not to touch wet electrical equipment, MDHHS says floodwater can contain raw sewage, and EPA says older homes may contain asbestos or lead. EPA, the Red Cross and MiReady also say children and people with asthma or weak immunity should not take part in cleanup.
