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
Champaign's growth since its 1855 founding has produced housing spanning well over a century of construction, much of it built before vapor barriers or mechanical ventilation were standard, sitting on Champaign County's historically poorly-drained black prairie soil. Central Illinois's humid summers working on that combination of older construction and slow-draining ground is what keeps moisture and mold assessment in steady demand across the Champaign-Urbana area.
Ask what will be hidden
A written scope should explain the preparation and verification that will no longer be visible at completion, not just the finished appearance.
Compare complete scopes
Look for protection, access, materials, permits, testing, cleanup, restoration, exclusions, warranties, and change-order rules.
What official local sources add
The City of Champaign requires a permit (a $70 fee) for new or modified connections to the municipal stormwater drainage system and is the permitting authority for land-disturbing activity, requiring an approved stormwater control plan for qualifying construction projects. Champaign coordinates that permitting with Champaign County, the City of Urbana, the University of Illinois, and the Village of Savoy through the Champaign County Stormwater Partnership's shared MS4 permit program. Moisture-source correction work that changes exterior grading or drainage can fall under Champaign's stormwater permitting requirements, worth checking before work begins.
