Why mold is common in Springfield
Abraham Lincoln Capital Airport averages about 38 inches of precipitation a year under NOAA's 1991–2020 normals, with May and June the wettest months, often in heavy thunderstorms. Humid summers slow drying in basements, and cold winters bring condensation on foundation walls and windows.
About 65% of Springfield's homes were built before 1980, and about 18% before 1940, according to the Census Bureau. Older houses near downtown, in Enos Park and the historic districts around the Lincoln Home, and postwar homes across the west side mostly have full basements with block or brick walls that let groundwater through. Sump pumps, floor drains, and downspouts that drain beside the house decide whether a basement stays dry.
A basement dried within a day or two, as the EPA recommends, rarely grows mold.

Illinois mold licensing: what to check
The state's new mold remediator registry is on the books but not running, so a Springfield homeowner has no state record to check. Ask the company which mold certification its technicians hold, get a copy of its insurance certificate, and find out from City Hall whether finishing the basement back out needs a permit. See the Illinois page.
Will insurance cover it?
In a Springfield basement, the endorsement decides the claim. A failed sump pump or a floor drain backup is usually covered only with a backup endorsement. Groundwater seeping through the wall is generally excluded, and creek or river flooding needs a flood policy. A burst pipe is more likely to be covered, with a mold limit. The Illinois Department of Insurance handles complaints. See does insurance cover mold.
