Verify the CSLB license at cslb.ca.gov. Confirm general liability and workers comp insurance. Get 3 references with photos. Get a written fixed-price contract. Never pay more than 10% or 1000 dollars upfront.
Go to cslb.ca.gov and enter the contractor's license number. Check: license is active, bond is current, workers' comp insurance is active, and there are no outstanding complaints. NP Line Design: #1105249 — active, bonded, insured. This 2-minute check eliminates 90% of bad contractors.
Request certificates of: General liability insurance ($2M minimum) and Workers' compensation insurance. Call the insurance company to verify — certificates can be forged. If the contractor doesn't have workers' comp, YOU are liable if a worker is injured on your property.
Ask for references from projects similar to yours in size and scope. Call them. Ask: Was the project completed on time? On budget? Were there surprises? Would you hire them again? Visit a completed project if possible — photos don't show quality of trim work and finishes.
The contract should include: detailed scope of work (not just 'kitchen remodel'), fixed price, payment schedule tied to milestones (not dates), start and estimated completion date, change order process, warranty terms, and license/insurance numbers. California law: never sign a contract exceeding $500 without these elements.
No license number on business card or contract. Requests cash payment. Demands more than 10% or $1,000 upfront (California law maximum). No written contract. Pressures you to sign immediately. Can't provide local references. Shows up in an unmarked vehicle. Offers a 'special discount if you sign today.' Any of these = walk away.
