Best business loans for plumbing companies in 2026
The best financing for most plumbing companies is equipment financing for trucks and specialty tools, with a business line of credit behind it for commercial jobs that pay on 30-day terms or longer. Plumbing demand is steadier than most trades, so plumbers usually qualify on consistent deposits and need financing for growth more than survival.

The short list
- Best for trucks, jetters, and cameras

- Best for adding a crew

- SBA 7(a) loan
The 4 best options, ranked
1. Equipment loan Best for trucks, jetters, and cameras
A stocked service truck, a hydro-jetter, or a sewer camera pays for itself in billable work. Financing each against its own value preserves cash for payroll.
Watch for: Older or highly specialized equipment gets shorter terms and higher rates. Equipment financing guide →
2. Business line of credit Best for commercial and new-construction jobs
Service calls pay at the door, but commercial and new-construction plumbing pays on draws. A line carries materials and labor until the general contractor pays.
Watch for: Some lenders add draw or maintenance fees, and a limit can be cut at renewal. Business line of credit guide →
3. Online term loan Best for adding a crew
Hiring and outfitting another crew is a known, one-time cost. A fixed-payment loan funds it with a clear payoff date.
Watch for: A longer term lowers the payment but raises the total interest you pay. Term loan guide →
4. SBA 7(a) loan Best for buying a shop or a competitor
For established plumbers, a 7(a) loan finances a building or an acquisition over a long term at a capped rate.
Watch for: Heavy documentation, and the timeline rules it out for anything urgent. SBA loan guide →
Side-by-side comparison
| Option | Verdict | Cost basis | Funding speed | Qualifies on |
|---|---|---|---|---|
| Equipment loan | Best for trucks, jetters, and cameras | Representative 8%–30% APR, with the term matched to the equipment's useful life | Days to weeks | The equipment is the collateral, which can offset a thinner credit profile |
| Business line of credit | Best for commercial and new-construction jobs | Representative 8%–30% APR, charged only on what you draw | Often days | Revenue, time in business, and credit |
| Online term loan | Best for adding a crew | Representative 8%–30% APR, fixed payments over 6 to 60 months | Days | Revenue, time in business, and credit |
| SBA 7(a) loan | Best for buying a shop or a competitor | Capped at 10.00%–13.50% by loan size (prime plus the SBA maximum spread) | Weeks to months | Generally stronger credit and two or more years in business |
What it costs
Monthly payments on a standard fixed-payment loan at the representative 8%–30% APR band. The low end of each range is 8% APR and the high end is 30% APR.
| Amount | 36 mo | 48 mo | 60 mo |
|---|---|---|---|
| $30,000 | $940–$1,274 | $732–$1,080 | $608–$971 |

Financing $80,000 over 48 months costs about $1,953–$2,880 a month, or $13,746 to $58,263 in total interest, depending on the rate you qualify for. WithFunded calculation, representative 8%–30% APR band. Not a quote.
A line of credit charges interest only on the balance you have drawn. This is the monthly interest on a carried draw, before any principal is repaid:
| Carried draw | At 8% APR | At 19% APR | At 30% APR |
|---|---|---|---|
| $25,000 | $167 | $396 | $625 |
| $60,000 | $400 | $950 | $1,500 |
| $120,000 | $800 | $1,900 | $3,000 |

What lenders look at
- Consistency of deposits. Steady service revenue is a plumbing company's strongest argument.
- Licensing and how long the master license holder has been with the business.
- The share of revenue from new construction, which is more cyclical than repair work.
Mistakes to avoid
- Paying cash for a truck and then borrowing at a higher rate for working capital a few months later.
- Taking on a large commercial job without checking how its payment terms line up with your credit limit.
Frequently asked questions
- What is the best way to finance plumbing equipment?
- An equipment loan or lease secured by the equipment. Terms are matched to useful life, and approval leans on the asset, so it is usually easier to get than an unsecured loan of the same size.
- Do plumbers need a line of credit?
- A plumber doing mostly residential service can run without one. Once commercial or new-construction work is a real share of revenue, a line becomes close to essential because costs come weeks before payment.
- Can I get an SBA loan for my plumbing business?
- Yes, if you have solid credit and typically two or more years in business. SBA loans take weeks to months, so they suit planned moves like a building purchase, not an urgent need.

Landon and Austin were greatLandon and Austin were great. Knowledgable and explained everything in a way that made it all really easy to understand. I avoid these call like the plague but these two were a joy to work with.
Highly recommendedHighly recommended! I worked with Corey, and he was awesome. He found an option after I received multiple rejections that no other company had presented to me. It was within my budget and my timeline. I'm so thankful!
BTC has become my go to for working…BTC has become my go to for working capital. Recently, my company was in a bind and needed funds. The BTC team, headed by Drew, took a problem solving approach and helped to overcome an initial denial, resulting in a better facility than the one I was turned down for. Thanks BTC! Thanks Drew!

How we ranked these options
This guide ranks types of financing, not individual lenders. Each option is ordered by how well it fits the need described on this page, judged on four things in this order: whether the structure matches how the money will be used and repaid, total cost, funding speed, and how hard it is to qualify. Cost figures are WithFunded calculations from published rate inputs as of November 2026: the bank prime loan rate from the Federal Reserve, the SBA maximum-rate schedule, and Federal Reserve survey data. The method follows our 2026 SMB Financing Cost Report, whose own figures use June 2026 rates.
WithFunded is a financing marketplace, not a lender. Our 2-minute form suggests a product type from the families we cover, and a funding partner reviews the request. Not every structure named in this guide is available through WithFunded: options such as SBA microloans, USDA farm loans, bank loans, and seller financing are ones you would pursue directly with the provider. They are listed because leaving out a good fit would make the ranking less useful.
