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
A foundation evaluation in the Evansville area has to start with which of those two soil conditions -- river-lowland alluvium or bluff-top loess -- a given property actually sits on, since settlement patterns, drainage needs, and crawlspace conditions differ meaningfully between them, and that's before accounting for the additional coal-mining-era ground found throughout Warrick and Gibson counties to the east and west.
Ask what will be hidden
Cracks and sticking doors are clues, not diagnoses. Soil moisture, grading, drainage, framing, and foundation type need to be considered together before a repair plan is proposed. The written scope should explain the preparation and verification that will no longer be visible at completion.
Compare complete scopes
Look for protection, access, materials, permits, testing, cleanup, restoration, exclusions, warranties, and change-order rules.
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.
