Write down what you're observing
Note where it's located, when you first noticed it, any connection to weather or humidity, how it's changed over time, and whatever repairs have already been attempted. A few photos and rough measurements go a long way toward a more useful first conversation.
Read the local context
Lansing's housing stock runs from early-1900s in-town homes near the Grand River and Red Cedar River confluence through a long run of postwar ranches built during the Oldsmobile and REO Motor Car Company years, with new construction filling in outlying areas since the 2005 plant closure freed up land for redevelopment. Mid-Michigan winters bring roughly 46 inches of snow a year with hard freeze-thaw cycling, and that seasonal moisture swing, combined with older crawl spaces and basements sitting on clay-heavy glacial till, keeps humidity and moisture-source work in steady demand across the capital region.
Ask about what gets covered up
What you can see is rarely the whole extent of the problem. A workable plan traces water entry, humidity, the condition of affected materials, containment during the work, and a way to verify results afterward. Ask the provider to spell out, in writing, exactly what preparation and testing happens before everything gets closed back up and is no longer visible.
Weigh full scopes against each other
When comparing proposals, look past the bottom line to how each one handles surface protection, site access, material choices, permits, testing, cleanup, restoration, exclusions, warranty terms, and what happens if the scope changes mid-project.
What the city's own sources add
The City of Lansing maintains dedicated floodplain-permit and stormwater/sewer program pages, including a Basement Backup Protection Program, because the Grand River and Red Cedar River corridors that run through the city carry mapped flood risk. Work proposed near mapped flood hazard areas, or work affecting drainage and grading, should be checked against current City of Lansing requirements before it begins.
