Document the condition
Note location, timing, weather relationship, changes over time, and any previous work. Photos and simple measurements can improve the first conversation.
Read the local context
Homes from that pre-1920s building wave went up decades before vapor barriers, crawlspace ventilation standards, or real moisture-control expectations existed, and a fair number sit close enough to the St. Joseph River corridor to have flooded more than once in the city's recorded history. That combination of age and river-adjacent ground is exactly what keeps moisture control a live issue for South Bend's older housing stock.
Ask what will be hidden
By the time drywall goes back up, nobody can see whether the crew actually corrected the moisture source or just treated what was visible — put in writing what gets verified before the walls close, not after.
Compare complete scopes
Look for protection, access, materials, permits, testing, cleanup, restoration, exclusions, warranties, and change-order rules.
What official local sources add
Neither program governs remediation, and their value here is upstream. Most persistent moisture in this housing stock is a site-drainage problem before it is an indoor one, and correcting it means regrading or changing where water discharges -- which is precisely what the MS4 program covers. The flood-zone check the city recommends is worth doing for a different reason: it tells you whether the property has taken water before, which changes what an assessment should look for inside wall cavities rather than only on their surfaces.
