Does a foundation repair contractor need a license in Illinois?
Contractor licensing is set by each state, and some leave it to cities or counties. Some states license this work at state level (for example the CSLB in California, the Registrar of Contractors in Arizona or the DBPR in Florida); others only require registration or local licenses. Check the license or registration number on your state's or city's public lookup before you pay a deposit, and ask for proof of liability insurance.
How are companies in Illinois chosen?
They come from Google Maps searches for foundation repair in each state; we read each website for the repairs it names. Nobody pays for a position. See how this directory works.
