Estimate your repair in the calculator Is my quote fair?

Before you hire

• Ask how far the wall has moved and whether the plan stops movement or also straightens it
• Ask whether anchors need room in the yard (and neighbors' consent near a property line)
• Ask for drainage to be part of the plan
• For walls over about 2 inches of movement, get an engineer's opinion

Permits, codes and licensing

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.
