Why Basements Leak After Rain
The puddle rarely sits under the leak. Water tends to enter where wall meets slab, at cracks in poured walls, through worn mortar in block or stone, around pipe openings and in window wells that fill up.
In April 2013, nearly ten inches fell over two weeks (WOOD-TV), the Grand River set a downtown record near 21.85 feet on April 21, and many homes and businesses saw basement flooding (CBS Detroit, citing the National Weather Service). A hail-and-rain storm on March 10, 2026 brought close to 3 inches, and some city residents found water in their basements (WOOD-TV).
During one wet stretch, with Lakes Michigan and Huron at a record July level, a City Environmental Services superintendent told WOOD TV that groundwater was "getting into more basements than we've ever seen this year." A sump that keeps cycling days after the rain stops often points to a high water table.
Water rising from a floor drain is different: that is a sewer backup, and waterproofing won't stop it. Since the City completed its $400 million sewer separation in 2015, rain and sewage travel in separate pipes. The City treats the lateral as the resident's responsibility, so the lateral, any footing-drain connection and the water table are the places to ask about.

Jobs That Fall Under Basement Leak Repair
- One crack that seeps. Usually injected from inside, with no digging.
- Worn joints in block, brick or stone. Repointing where mortar has gone soft.
- Seepage at the floor edge. A short interior drain run to a sump that empties into the yard.
- Roof water dropped at the wall. Clean gutters, longer downspouts and soil sloped away from the house.

How the Work Usually Goes
- Tracing the source. Followed back past the wet spot, outdoors as well as in.
- A written estimate. The repair, its location, materials and warranty terms, signed by both of you first.
- Your checks. Search the license on LARA's online license verification and ask who pulls any permit.

Why Homeowners Use This Service
This site passes your request to one independent local contractor and steps aside. It is not a contractor or anyone's agent, holds no Michigan builder or maintenance and alteration contractor license, quotes nothing and stays out of insurance. Contractors may pay a flat advertising fee (waived during a free trial); homeowners never pay and are never paid.
What Insurance Usually Covers Below Grade
Sewer-backup coverage is often a separate endorsement and gradual seepage is commonly excluded, so check the wording and ask your insurer or agent. The City strongly urges residents to carry backup coverage. If you think a City sewer caused a backup, the City requires a written damage claim within 45 days under Michigan's PA 222; its Risk Management office is 616-456-3467. That process is the City's own, and this site has no role in insurance.

Answers Before You Call
Where do I report water coming up a floor drain?
Inside the City of Grand Rapids, dial 311, or 616-456-3000 from outside the City, to reach Environmental Services; the City notes that time of day and workload affect how quickly crews respond. In a suburb, contact your own city or township's public works office instead.
Why does the leak only show up in spring?
Snowmelt and spring rain soak the soil and raise the water table together, so pressure on the walls peaks then; a midwinter thaw can do the same thing. Tell the contractor which months it happens, which helps separate runoff from groundwater.
Does stopping a leak mean digging up the yard?
Rarely. A lone crack or weak joint is normally sealed from inside, and the outdoor part is often just a longer downspout or soil regraded to fall away from the house. Excavation mostly comes up when one wall leaks along its whole length.
Who is responsible for the sewer lateral?
Inside the City, the owner. When City crews trace a problem to the lateral, the City says the owner arranges for a plumber or sewer cleaner to check or clean it. Repairing that line, or adding a backwater valve, is plumbing for a licensed plumbing contractor with a permit.
