What's My Plumbing Business Worth in 2026?

It's one of the most common questions a plumbing business owner types into a search bar late at night, usually after a good year or a bad one: what's my business actually worth? The results are almost always the same: A stack of articles with vague ranges that never quite seem to describe a business that looks like yours.

That's the frustrating part. There isn't a single number you can look up. What buyers actually pay comes out of a calculation of your revenue tier, your adjusted EBITDA, and a handful of factors that move the multiple up or down. Once you understand how that calculation works, the vague ranges online start to make a lot more sense.

Start With Adjusted EBITDA, Not Revenue

Buyers don't price plumbing businesses off revenue. They price them off adjusted EBITDA (earnings before interest, taxes, depreciation, and amortization) adjusted further for owner compensation above market rate, personal expenses run through the business, and one-time costs that won't carry over to a new owner.

Two plumbing businesses with identical revenue can land at very different adjusted EBITDA numbers once those adjustments are made. That's usually the first place a real valuation starts to pull away from a rough guess based on top-line sales.

What Your Plumbing Business Is Worth, by EBITDA Tier

Smaller, owner-operated businesses, generally those with adjusted EBITDA under roughly $500,000, have historically sold at the lower end of the multiple range, often in the low single digits. At this size, the business still tends to lean heavily on the owner personally, and buyers price that risk in.

Established businesses in the $500,000 to $1.5 million adjusted EBITDA range have historically traded in the 3.5x to 5.5x range, with businesses that show documented recurring revenue and some independence from the owner landing toward the top of that band.

Businesses with $1.5 million to $3 million in adjusted EBITDA have historically commanded stronger multiples, often in the 5x to 7x range. At this size, there's usually more infrastructure in place, a management layer between the owner and the crews, and a customer base that isn't riding on any single relationship.

Above $3 million in adjusted EBITDA, plumbing businesses start attracting serious interest from private equity-backed platforms building out regional footprints, and multiples at this tier have historically moved higher still. Where you land depends heavily on growth trend, recurring revenue percentage, and how active buyers currently are in your specific market.

It's worth noting that these ranges aren't fixed. They move with the broader deal-making environment. Interest rates are one of the clearer examples: acquisition financing gets more expensive when rates rise, which tends to compress the multiples buyers are willing to offer, and financing gets cheaper and multiples tend to loosen back up when rates come down. The Federal Reserve has held its benchmark rate at 3.50%–3.75% through mid-2026, according to the Fed's own H.15 report, after a multi-year run of increases and cuts. Context that matters if you're trying to time a sale.

The broader small-business market backs up the general direction, too. Across the service-business category as a whole, median sale prices have climbed by an average of roughly 8% a year over the past five years, according to BizBuySell's aggregated valuation data, one of the more reliable public benchmarks for how buyer demand and pricing have trended in this space.

None of this replaces getting a real number for your specific business. Our Ask NorthBase tool at northbase.com/asknorthbase can give you a starting point based on your revenue and EBITDA tier, and from there, a conversation about your actual financials gets you a far more accurate picture.

What Pushes You Toward the Higher End of Your Tier

A few things consistently move a business toward the top of its range.

• Recurring revenue. Maintenance agreements and service contracts make your income predictable, and predictable income lowers a buyer's risk.

• Clean, documented financials. Itemized add-backs let a buyer trust the number you're presenting instead of discounting it out of caution.

• Real operational independence. If the business runs without you personally handling every pricing decision or key customer relationship, that tells a buyer it will keep performing after you're gone.

What Mike Learned About His Own Number

Mike is one of the owners who typed that question into a search bar. When he finally got a real valuation instead of a guess, his adjusted EBITDA landed him solidly in the middle tier — higher than the number he'd been quietly assuming for years, mostly because he hadn't been accounting for his above-market compensation or a handful of legitimate add-backs.

The multiple he ended up with reflected his strong maintenance agreement base and a customer concentration issue he'd already worked to bring down. It wasn't the vague range he'd found online that night. It was a specific number tied to his specific business.

Looking back, Mike says the real value wasn't the number itself. It was understanding exactly which levers moved that number and which ones he still had time to pull before going to market. That's the difference between a rough guess and a real valuation you can actually plan around.
