Verify the license and insurance

Any contractor building a block or retaining wall in Orange County should hold a valid California contractor license and carry liability insurance. Ask for the license number and verify it on the CSLB website. (RIVO Construction is CA Lic #1148578.)

Ask about engineering and permits

Walls over about 4 feet, or any wall retaining soil, usually require permits and engineered plans. A good contractor handles this and won’t suggest skipping it — unpermitted walls cause problems at resale and can fail inspection.

Questions worth asking

• How do you handle drainage behind retaining walls?
• What footing depth and rebar will you use?
• Can I see photos and reviews of local projects?
• Is demolition and haul-away included?
• What’s your written warranty?

Look for local reviews
