The short answer: The 2025 median plumbing sale price was about $837,500 (up 46% from 2022). Price = SDE × the ~2.62× multiple. With an SBA 7(a) loan you need a 10% equity injection, $80K on an $800K shop, and up to half can be a seller note on standby, so your own cash can be as low as ~$40,000 plus closing costs, working capital, and the cost of securing a master-plumber license. Run it in the valuation calculator.
What plumbing businesses actually cost
| Business | Revenue | SDE | Typical price |
|---|---|---|---|
| Small owner-operator | $400K, $700K | $90K, $180K | $240K, $470K |
| Established shop (median deal) | ~$1.29M | ~$277K | ~$838K |
| Larger commercial firm | $2M, $5M | $400K, $1M | $1.3M, $5M+ |
The median sale price climbed from $572,500 in 2022 to $837,500 in 2025, a 46% jump, as demand surged, margins hit a five-year high, and PE consolidators entered. Within a size band, the biggest price driver is revenue mix: commercial recurring beats residential service beats new construction.
How the price is set: the multiple
Main Street plumbing deals price off SDE × a multiple. The median runs about 2.24×, 2.62×, but mix swings it hard:
| Multiple | Implied price | When it applies |
|---|---|---|
| 2.0× (low) | $554,000 | New-construction-heavy, owner-dependent |
| 2.62× (anchor) | $725,000 | Typical residential-service shop |
| 4.5× (high) | $1,246,000 | Commercial recurring-maintenance, manager-run |
Same $277K of earnings, a $692,000 spread in price, all driven by revenue quality and owner-dependence. See the live figure on plumbing multiples.
The fastest way to overpay for a plumbing business is to pay a commercial multiple for new-construction revenue. Know which dollars you're buying.
The down payment and full capital stack
| Source / use | Amount | % of price |
|---|---|---|
| SBA 7(a) bank loan | $720,000 | 90% |
| Your cash injection | $40,000 | 5% |
| Seller note (full standby) | $40,000 | 5% |
| Purchase price | $800,000 | 100% |
| + Est. closing costs & fees (financed) | ~$30,000 | |
| + Working-capital reserve | $40K, $60K |
So real "cash to close" is your ~$40,000 injection plus a working-capital cushion, not $800K. Note plumbing deals often carry heavier seller financing (SBA buyers commonly ask for 20 to 30% seller notes, with only part on standby). The loan is sized to a DSCR of ~1.15×, 1.25×.
Does this deal cash-flow?
At $277K SDE and ~$110K annual debt service, DSCR is about 2.5× before owner salary. After reserving a $130K market salary (or a master-plumber's), it's still comfortably above 1.25×. Verify in the DSCR guide.
Plumbing-specific costs buyers forget
- Securing the license. If you're not a master plumber, budget for retaining the seller's license-holder or hiring a qualifying master plumber, a recurring payroll cost, not a one-time fee.
- SBA guarantee & packaging fees, usually financed into the loan.
- Legal, closing & quality-of-earnings, verify those add-backs behind SDE over a 60 to 90 day diligence window.
- Bonds & insurance, GL of $500K, $1M and municipal permit bonds.
- Fleet & equipment capex, aging trucks and jetters are near-term cash needs.
- Working capital, a buffer for the seasonal slow stretch.

Frequently asked questions
The 2025 median sale price was ~$837,500, up 46% from 2022. Small shops sell for a few hundred thousand, larger commercial firms into the millions. Price is SDE × the ~2.62× multiple. See plumbing multiples.
An SBA 7(a) loan needs a 10% injection, $80K on an $800K shop, and up to half can be a standby seller note, so your own cash can be as little as ~$40,000 plus closing costs and working capital.
Median prices rose 46% from 2022 to 2025 as demand surged, sold-shop margins hit a five-year high (~26.7%), and PE consolidators entered. Non-discretionary demand and recurring revenue attract both SBA buyers and roll-up platforms.
SBA fees, legal/closing, a quality-of-earnings review, and, unique to plumbing, securing a licensed master plumber if you aren't one. Also reserve working capital for the slow season. Many costs can be rolled into the loan.
