Quick Answers
These replies are general by nature; your own walls and drains may change them.
Is this site a contractor, and what does asking cost me?
No, and asking is free. Because the site has no Michigan residential builder or maintenance and alteration contractor license, basement work is never something it offers or agrees to. Your request goes to one independent local contractor, who reaches out and writes its own estimate. A contractor can buy a flat-fee ad here, waived during a trial; you are never charged or rewarded.
Why do so many basements in Grand Rapids take on water?
Age and ground both matter. Census survey figures show more than a third of the City's housing was built before 1940, with a median build year around 1953, so older stone, brick and block foundations are common. The USGS found that glacial sands and gravels along the rivers hold the most groundwater, and spring rain or a midwinter thaw can raise it.
Water came up through my floor drain. Is that seepage?
Usually not; it points to a sewer backup. Inside the City, report it to 311, or 616-456-3000 from outside city limits. The City treats the lateral, the pipe from your house to the main, as the owner's to look after. If you believe a City sewer caused the backup, the City wants a written claim within 45 days (Risk Management, 616-456-3467). In a suburb, reach your own city or township.
Didn't the City already separate its sewers?
It did. A $400 million project begun in 1991 wrapped up in 2015, laying 119 miles of new pipe and closing all 59 overflow points, so rain and sewage now run in separate pipes. Worth asking about: your lateral's condition, whether a footing drain feeds the sanitary line, and how high groundwater sits.
What is the City's Footing Drain Disconnection Program?
The City uses it to pull footing drains off the sanitary sewer, where extra water can cause basement backups. The City picks the neighborhoods, taking part is required inside them, its FAQ caps the City's share of reasonable costs at $4,500, and City pre-qualified contractors do the work (616-456-3057). A separate City backwater valve and sump program exists too; ask the City whether it is taking new properties.
What does basement waterproofing usually cost?
Fixr's 2026 national numbers show most whole projects landing between about $3,000 and $10,000, averaging close to $5,000. By the same source, an interior perimeter drain runs $40 to $120 per linear foot, a new sump pump $600 to $2,500, and epoxy injection $250 to $1,000 for each crack. No Michigan-only study exists, so your written estimate is the figure that counts.
How do I look up a contractor's license?
Michigan's Department of Licensing and Regulatory Affairs (LARA) licenses residential builders and maintenance and alteration contractors, and "waterproofing a basement" is one of the listed trades. The Attorney General suggests asking for the 10-digit license number, and LARA calls a contractor who can't produce one a red flag. Search it on LARA's online license verification at michigan.gov/lara.
What should the contract say, and how should I pay?
Michigan's rule wants a written agreement signed by you and the contractor that spells out the price, what work will be done and how much of it, and which materials go in at what quality, with a copy for you. Changes get the same treatment. LARA advises paying in stages as the job moves, and written lien waivers before the final payment are a sensible precaution.
Can I back out after signing?
Often. Under the Michigan Home Solicitation Sales Act, when a sale over $25 was pitched to you at home, face to face, through a call or in writing, a buyer who said yes there can generally undo it up to midnight on the third business day after signing. A genuine emergency can set that aside, but only through a separate statement you write by hand, date and sign.
Will my homeowners policy pay for basement water?
Maybe. Backup protection is often an add-on endorsement rather than standard, and water that slowly seeps through walls is a frequent exclusion. The City of Grand Rapids urges residents to carry sewer-backup coverage. Read your policy and take the question to your insurer or agent; this site stays out of insurance matters.
