Who We Write in This Trade

Solo service plumbers, 2-truck residential service operations, mid-sized residential new-construction plumbing contractors, and commercial mechanical contractors doing $5M+ in annual work.

Carrier Appetite

Standard NJ panel: Travelers, The Hartford, Nationwide, AmTrust, Merchants Mutual, Next. Service plumbers and small new-construction operations are typically standard-market placements. Mechanical contractors doing significant commercial work fit cleanly with Travelers and The Hartford. Loss history and water damage frequency are the main rating drivers.

The Coverage Stack You’ll Want

  • GL — $1M/$2M standard. Water damage to finished spaces is the most common claim — subrogation by property carriers is aggressive. Products-completed operations matters (a fitting that fails 18 months after install is your claim).
  • Workers Comp — class codes split between service plumbing, new construction, and supervisor payroll. Getting the split right saves real money.
  • Commercial Auto — trucks, vans, trailers, employee drivers.
  • Tools & Equipment — service vans full of tools, fittings inventory, equipment. Installation floater for customer-supplied fixtures (water heaters, boilers, fixtures bought via plumber for install).
  • Commercial Umbrella — recommended; sits over GL, Auto, and EL.

NJ-Specific Considerations

  • NJ master plumber license required for the supervising plumber on each job. We confirm licensure at intake.
  • Backflow prevention certification — separate cert, sometimes required for commercial.
  • Water damage subrogation: NJ property carriers are aggressive about subrogating water damage claims back to the plumbing contractor. Your GL needs to be structured to defend these efficiently.
  • Lead and copper work — pre-1986 buildings may have lead service lines; underwriting language sometimes addresses lead exposure.
FAQ

Common questions.

Solo service plumber — what does a typical program cost?
Rough order: $1,800–$3,500/year total for GL ($1M/$2M), Auto (one service van, $1M CSL), Tools ($15K), and Umbrella ($1M). WC if you’re an LLC/corp electing in adds $1,800–$3,000 depending on class code and payroll. We quote your actual numbers.
What about new construction vs. service?
Different class codes on WC, sometimes different sub-rates on GL. We split the operations at quote so you’re not paying new-construction rates on service revenue or vice versa.
Do you handle the master plumber license confirmation for the carrier?
Yes — most carriers require the supervising license number on the application. We capture it on the intake.
What about commercial backflow work?
Cert-dependent. Backflow prevention work generally fits standard market; we confirm the cert and quote alongside the main program.
Water damage on a finished home — how often does GL get hit?
It’s the most common contractor GL claim in NJ. Property carrier subrogates against you, your GL defends. Make sure your products-completed operations limit is adequate and your additional insured endorsements are correct.
