Short answer: usually no. Standard Michigan homeowners insurance treats basement waterproofing as home maintenance, so the waterproofing system itself (drain tile, membrane, sump pump, exterior excavation) is almost never covered. What can be covered is the damage from a sudden, accidental event – and only if you have the right add-ons. Here is how it actually plays out for homeowners in Macomb and Oakland counties.
What a standard policy does and doesn’t cover
- Not covered – seepage and groundwater. Water that comes in through the cove joint, a foundation crack or the floor because of hydrostatic pressure is “seepage,” and nearly every policy excludes it. The same goes for a slow leak you didn’t notice for weeks.
- Not covered – the waterproofing work itself. Interior or exterior waterproofing, crack injection, drain tile, membranes and grading are considered preventive maintenance.
- Sometimes covered – sudden and accidental damage. A burst supply line or a water heater that lets go all at once is typically covered under the standard “sudden and accidental discharge” language. The cleanup and the damaged finishes may be paid; the cause of the leak often is not.
- Covered only with a rider – sewer and drain backup. City sewer backups and sump pump failures are excluded by default. Most Michigan carriers sell a “water backup / sump overflow” endorsement for roughly $40–$150 a year. In older neighborhoods with combined sewers (parts of Warren, Royal Oak, Eastpointe, St. Clair Shores, Detroit) this rider is worth every dollar.
- Separate policy – flooding. Water that rises from outside (overland flooding, a creek, a storm surge) is only covered by flood insurance (NFIP or private), not by homeowners insurance.
Why insurance usually says no to waterproofing
Insurers cover sudden events, not conditions that develop over time. A leaking basement in Michigan clay is almost always a drainage problem that built up over years: a plugged footing drain, a sump pump that is undersized, downspouts dumping next to the foundation, or a cracked wall that lets water in every spring. Because the fix (a drainage system) prevents future damage instead of repairing a one-time loss, it is treated as an improvement you pay for.
What to do before you call your insurance company
- Figure out where the water came from. A sudden pipe failure is a claim. Groundwater seepage is not. If you are not sure, a quick inspection (we do these across Macomb and Oakland counties) tells you before you open a claim that might be denied and still count against you.
- Read your declarations page. Look for “water backup,” “sump overflow” or “sewer backup” coverage. If it isn’t there, ask your agent to add it – it is one of the cheapest endorsements you can buy.
- Document everything. Photos of the water line on the wall, the failed pump, damaged drywall and flooring, plus the date and the weather that day.
- Stop the damage. Policies require you to prevent further loss. Pumping out water, removing wet drywall and running fans are reasonable steps and are usually reimbursable when the loss is covered.
Cheaper than a claim: protection that pays for itself
Most of the basements we pump out every spring could have stayed dry for less than the deductible on one claim:
- A backwater valve on the main sewer line stops city sewer surges from backing up into the basement.
- A properly sized sump pump with a battery backup keeps running when the power drops during the storm.
- Crack injection seals the vertical cracks and rod holes that leak every heavy rain.
- For chronic seepage, a full interior drainage system or exterior waterproofing fixes the cause – and our waterproofing work carries a 25-year transferable limited warranty.
Frequently asked questions
Does homeowners insurance cover a leaking basement in Michigan?
Only if the leak is sudden and accidental, such as a burst pipe. Groundwater seepage through walls, floors or cracks is excluded on standard policies.
Does insurance cover a sump pump failure?
Not unless you carry a water backup / sump overflow endorsement. Check your declarations page; the rider is inexpensive and worth adding before spring.
Does insurance cover foundation crack repair?
Rarely. Cracks from settling, soil pressure or freeze-thaw are considered wear and tear. Crack injection is usually a few hundred to a couple thousand dollars and is paid out of pocket.
Will a waterproofing system lower my premium?
Some carriers give a small discount for a backwater valve or a sump pump with battery backup, and a documented waterproofing system with a transferable warranty helps when you sell. Ask your agent.
