For plumbing contractors

The van is stocked, the crew is paid, and the pay app is still in review.

A plumbing company buys the parts, the vans and the hours before any customer pays for them, and on new construction it waits on pay applications and retainage. The Business Funding Club is a free referral club: we send plumbing contractors to ROK Financial. ROK and the lenders it matches you with review each request and make every funding decision.

The math

The math

  1. BEFORE THE JOB

    You stock the van

    Fittings, valves and water heaters ride on the truck so the tech can finish in one trip. That stock is paid for before it is installed.

  2. EVERY PAY PERIOD

    You pay the crew

    Plumbers and apprentices are paid whether the invoice is out or not. Apprentices typically get about 2,000 hours of paid on-the-job training a year[1].

  3. MONTH END

    You bill the rough-in

    On a federal fixed-price job, progress payments are made monthly as the work proceeds[2].

  4. CLOSEOUT

    You collect what was held

    On a North Carolina public job of $150,000 or more, the owner can hold no more than 5 percent of each periodic payment to the prime contractor, released after substantial completion[3].

This is how plumbing is paid, not a sign of trouble. The more new-construction work you win, the more payroll and pipe you carry before the draw reaches you.

This page is about financing your plumbing business

Many searches for "plumbing financing" come from homeowners who want to pay for a repair over time. This page is for plumbing contractors who want capital for their own company. ROK Financial works with businesses. It does not offer consumer financing for your customers.

Service plumbing and new construction run on different clocks

Most plumbing companies do both, and they pay very differently.

Two cash cycles in one plumbing company (examples, not every contract)
Service and repairNew construction
Who paysHomeowner, property manager or commercial accountGeneral contractor, developer or public owner
When you billWhen the job is done, or on a commercial account's termsMonthly progress billing on federal work[2]
What is held backUsually nothingRetainage: up to 10 percent on federal work if progress is not satisfactory[2]; up to 5 percent on NC public jobs of $150,000 or more[3]

Service work has its own costs. Plumbers are often on call for emergencies, so evening and weekend work is common[1]. On new construction you are usually a sub, and your money comes through the general contractor. In North Carolina, a contractor must pay its sub within seven days of receiving a periodic or final payment[4].

Check your state and your subcontract

These are federal and North Carolina examples, and North Carolina's subcontractor rules exclude residential contractors and residential projects of 12 or fewer units, among others[4]. Read your contract and your state's rules. Our construction page covers pay-when-paid in depth.

Licensed crews, apprentices and payroll

Labor is the cost you cannot defer. Most states and some localities require plumbers to be licensed, usually after 2 to 5 years of experience and an exam[1]. Most plumbers learn through a 4- or 5-year apprenticeship[1], so a growing shop carries apprentices for years before they run calls alone.

BLS projects 7 percent job growth for plumbers, pipefitters and steamfitters from 2025 to 2035, with about 42,000 openings a year, and about 65 percent work for plumbing, heating and air-conditioning contractors[1]. The median annual wage was $63,800 in May 2025[1].

Vans, jetters, sewer cameras and lead service line work

Plumbers' tools include press fitting tools and drain cleaning tools[1]. The big-ticket items for a growing company:

  • Service vans with shelving, so each tech carries enough stock to finish in one trip.
  • Hydro-jetters for grease lines and root intrusion.
  • Sewer inspection cameras and locators to show the customer the problem and price the fix.
  • Pipe-bursting rigs for sewer laterals and water service replacement.
  • Parts inventory: water heaters and fixtures bought ahead of the jobs that use them.

Lead service line work is adding municipal demand. EPA estimates about 4 million lead service lines still serve properties nationwide[5], and its Lead and Copper Rule Improvements, issued in October 2024, require water systems to identify and replace lead pipes within 10 years[6]. The Bipartisan Infrastructure Law put $15 billion toward replacement through the Drinking Water State Revolving Fund[7], which flows from EPA to the states and from state agencies to water systems[8]. Funded projects must replace the entire line, not just a portion, unless part was already replaced[9].

For you, that usually means a public contract with a utility or city, paid on pay applications. EPA publishes Davis-Bacon wage guidance for contractors on State Revolving Fund work[10], and on covered work laborers and mechanics must be paid at least once a week[11]. Check current rules in the bid documents.

Equipment financing ties payments to the machine; ROK describes it as getting equipment through a loan or a lease[12]. Ask your tax preparer about Section 179, which lets a business elect to deduct eligible property in the year it is placed in service, within IRS limits[13]. See construction equipment financing.

What ROK will want to see

ROK's partner application lists at least 4 months in business and at least $10,000 in monthly gross sales, which is $120,000 a year[14]. Lenders commonly look at credit history, cash flow, equity and collateral[15]. For a plumbing company, have these ready:

  • Recent business bank statements showing service receipts and draws.
  • Your plumbing and contractor licenses.
  • Signed contracts and your last few pay applications.
  • A receivables aging, with retainage on its own line.
  • A dealer quote with make, model and year for any van, jetter or camera.
  • Your backlog, including any municipal or utility awards.

Credit is one input among several. ROK and the lenders it matches you with review each request and make every decision. The Business Funding Club does not. Size your gap with the cash gap calculator.

Financing that fits this kind of gap

Which one fits your business, if any, is a conversation to have with ROK’s advisor once they have seen your file. These are the types that usually come up.

Common questions

Is plumbing financing on this site for my customers?

No. This page is about financing your plumbing business: payroll, parts inventory, vans and equipment. ROK Financial works with businesses and does not offer consumer financing you could extend to homeowners. Customer payment plans are a different kind of program from a different kind of provider.

What do lenders look at for plumbing business loans?

Lenders commonly look at credit history, cash flow, equity and collateral[15]. For a plumbing company, bank statements, licenses, contracts, pay applications and a receivables aging tell the story. ROK's partner application lists at least 4 months in business and $10,000 in monthly gross sales[14]. ROK and its lenders decide.

Can I finance a hydro-jetter, sewer camera or service van?

Equipment financing is usually the closest fit, because payments are tied to the equipment instead of your working cash. ROK describes it as a loan or a lease[12]. Bring a dealer quote with make, model and year, and ask your tax preparer whether Section 179 applies[13].

What does The Business Funding Club cost?

Nothing. The Business Funding Club is a free referral club. We are not a lender and not a broker. We send your application to ROK Financial. ROK and the lenders it matches you with review it and make every funding decision. If your business is funded, ROK pays us a referral commission. You never pay the Club anything.

Plainly

What we are, and what we are not.

We are a referral club. We introduce small businesses to ROK Financial. That's the whole service, and it's free to you.

We are not a lender and not a broker. We don't fund anything, we don't quote figures, and we don't negotiate on your behalf. If someone tells you what your financing will look like before ROK has reviewed your file, that person is guessing.

We are paid by ROK, not by you. When a business we refer gets funded, ROK compensates us. You are never charged a membership fee or an application fee, by us or by anyone acting for us. Full disclosure here.
