Does a foundation repair contractor need a license in New Hampshire?
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.
