Document the condition first
Note the location, when it showed up, any weather pattern, how it has changed, and any earlier repairs. Photos and rough measurements make the first conversation more productive.
Read the Local Context
Housing that old has usually had its ventilation, crawlspace, and moisture-control systems altered or added onto more than once, and West Michigan's location in Lake Michigan's lake-effect snowbelt adds a heavy winter precipitation load on top of that -- February 2013 alone brought over three feet of snow to Grand Rapids -- both of which shape where hidden moisture tends to build up in the city's older housing stock.
Think about what gets hidden again
What's visible is only part of the story -- a workable plan also addresses water entry, humidity, material condition, containment, and verification once work is finished. The scope should explain what prep and checks happen before it's covered up again.
Compare full scopes, not just price
Look for protection measures, access, materials, permits, testing, cleanup, restoration, exclusions, warranties, and change-order terms.
What official local sources add
Grand Rapids participates in the National Flood Insurance Program, and land near the Grand River and its tributaries can fall within FEMA-designated Special Flood Hazard Areas, where projects may require an Elevation Certificate and compliance with the city's floodplain development standards under Chapter 32 of its code of ordinances. The city promotes Low Impact Development as its preferred stormwater strategy, and a 2021 state MS4 permit added a requirement that most development and redevelopment projects retain the runoff difference for the 2-year, 24-hour storm.
