Cash-only pricing may indicate tax avoidance or unlicensed operation.
Licensing and Insurance Issues
Inability to provide license numbers immediately disqualifies contractors.
Expired or suspended licenses indicate serious compliance problems.
No insurance verification creates liability risks for property owners.
Pressure Tactics and Unprofessional Behavior
Door-to-door sales pressure after storms or outages often indicates storm-chasing contractors.
Limited-time offers that require immediate decisions prevent proper vetting.
Reluctance to provide references suggests poor previous work quality.
No written contracts create disputes and liability issues.
Technical Red Flags
Unwillingness to pull permits indicates either inexperience or intentional code violations.
Vague installation descriptions suggest limited technical knowledge.
No site evaluation before quoting indicates inexperience with installation requirements.
Recommending inappropriate generator sizes suggests focus on profit over customer needs.
