Is a plumbing contractor bankable?

Emergency service is the most profitable revenue in the trades and the most bankable. New-construction plumbing is neither.

Written by the Transparent underwriting desk·Reviewed against equipment, line of credit and SBA 7(a) criteria·Reviewed

2,186 plumbing businesses closed an SBA 7(a) loan in FY2025–FY2026 — a median of $200,000 at 10.00%, with the cheapest quarter under 9.24%. Getting financed is not the unusual move in your industry; getting the cheap end of it is.

Three revenue types, three different credits

Plumbing revenue is not interchangeable, and lenders read the mix before they read the total.

  • Emergency and service — the best revenue in the trade. Collected at the door or within days, high margin, no receivable risk, and demand is non-discretionary.
  • Repair and replacement — good margins, homeowner-paid, occasionally financed.
  • New construction — the weakest from a credit standpoint. You are a subcontractor waiting on a GC, exposed to retainage, someone else's schedule, and payment terms you did not set.

A shop doing 70% service is a fundamentally better credit than one doing 70% new construction at the same revenue. If your mix favours service, say so with numbers — most contractors never mention it and it is the strongest thing on the file.

Recurring work exists here and is under-claimed

Backflow testing, grease trap service, commercial maintenance agreements and municipal contracts are contracted recurring revenue with renewal histories. They are worth far more to a lender than the same dollars of one-off work, and most plumbing shops present them as undifferentiated revenue.

What places, and what does not

  • Service trucks and vans — titled, easy, often zero down for established shops.
  • Jetters, camera and locating equipment, vacuum trailers — finance well when trailer-mounted and titled.
  • Hand tools and small equipment — bundled into a truck deal rather than financed alone.
  • Shop and yard real estate — SBA 504 territory, and usually the cheapest long-term money a growing shop can access.

Where plumbing files get declined

  • Cash-basis books that cannot separate service margin from install margin.
  • Subcontracted labor paid without documentation. Classification exposure a lender cannot size.
  • New-construction concentration with a single GC carrying the receivables.
  • Owner comp mixed into field payroll, making coverage impossible to compute.
  • Stacked advances taken to cover a slow winter.
