- Contractor's bond: $25,000 with North River Insurance Company (The). The bond is there to pay consumers and workers harmed by licence-law violations; it is not liability insurance and it does not guarantee the work.
- Workers' comp: Workers' Compensation Insurance with Service American Indemnity Company, policy through Jul 16, 2027.
