πŸ’‘ What TenPenny Vetting Means

Unlike other directories that let anyone list themselves, every TenPenny contractor goes through our 7-point verification process. We contact insurance providers directly, verify licenses with state databases, run background checks, and confirm reviews are from real customers. Then we sit down with them β€” every contractor gets a personal interview with our team so we can look them in the eye and make sure they share our standards for quality and customer service. Only contractors who pass every check earn the TenPenny Vetted badge. We re-verify quarterly to ensure continued compliance.
