Document the condition
Write down where the condition shows up on the Evansville property, when it started, how it tracks with wet or dry weather, and anything done about it previously; a handful of photos and basic measurements go a long way in that first call.
Read the local context
Figure out early which side of the local soil divide the property is on -- river-lowland alluvium down near the Ohio, or loess on the bluffs above it -- since drainage needs and crawlspace conditions diverge sharply between the two, well before the reworked coal-country ground in Warrick and Gibson counties even comes up.
Ask what will be hidden
Ask specifically what will be buried or covered once the work is done -- flashing, drainage fabric, pier connections -- because a written Evansville scope is only as good as what it documents about the parts nobody will see again after finish restoration.
Compare complete scopes
Line competing Evansville proposals up side by side on protection, access, materials, permits, testing, cleanup, restoration, exclusions, warranties, and change-order terms, not just the total price.
What official local sources add
Evansville's Riverside Historic District (added to the National Register in 1978) and the Lamasco / Independence Historic District document a 19th-century core of river-proximate construction built on the alluvial lowland described above, distinct from the loess-capped bluff ground under the city's later subdivisions.
