When completed work does not meet the standard you contracted for, you have both contractual and legal remedies. Here is how to approach the situation systematically.
Document Everything First
Photograph the defect, note when you discovered it, and describe the visible evidence. If there is active water intrusion, stop the water first — document original conditions before emergency repairs.
Notify the Contractor in Writing
Send written notice (email with read receipt, or certified mail) describing the defect. California law and most contracts require written notice before claims can be filed. Give the contractor 10–14 business days to respond with a proposed resolution.
CSLB Complaint
If the contractor does not respond or resolve the issue, file a complaint at cslb.ca.gov. The CSLB investigates complaints and can suspend or revoke licences. The Contractors Recovery Fund compensates homeowners up to $12,500 per project for losses from licenced contractor misconduct.
Legal Options
For disputes over $10,000, consult a construction attorney before escalating. Many disputes resolve through mediation faster and cheaper than litigation. Keep all project documents — contract, permits, change orders, payment records, communications.
