Water damage & mold help in Illinois
In Illinois, the basement is where most water damage happens. Chicago and many older suburbs are served by combined sewers that carry both stormwater and sewage, and heavy rain can push sewage back up through basement floor drains. Frozen pipes, sump pump failures and tornadoes round out the risks downstate.

Main water, mold and storm risks in Illinois
Basement flooding and sewer backup
Intense rain overwhelms combined sewers in Chicago and older suburbs, backing water and sewage into basements. Backwater valves and overhead sewers are common fixes.
Frozen pipes
Polar-vortex cold, like the January 2019 event, freezes pipes in exterior walls, garages and crawlspaces.
Sump pump failure
Power outages during storms stop sump pumps exactly when they're needed. Battery backups help.

Illinois questions
Is sewer backup covered by insurance in Illinois?

Do Illinois contractors need a license?
There's no statewide general contractor license, but Chicago and many suburbs require local licensing, and roofers need a state license.
