How Much Is A plumbing business Worth?
Plumbing businesses earn a solid trade multiple, built on essential, recession-resistant demand that doesn't wait for good times.
Averages across real reported sales of plumbing business businesses, businesses sold Q3 2021 – Q2 2026. Multiples are averages; sale price is the median.
A worked example
A business is worth its earnings times a multiple. Take a plumbing business with $265,000 of SDE and apply the average 2.61×:

Like HVAC, plumbing earns its multiple through repeat and emergency service work that doesn't depend on discretionary spending. The strongest sellers carry service agreements and a licensed team; pure new-construction plumbing, which rises and falls with the building cycle, prices lower and is harder for a buyer to underwrite.
What raises the multiple
- Recurring service and maintenance agreements
- Licensed plumbers who remain after the sale
- A service-and-repair mix over new construction
- Established commercial or property-management accounts
What lowers it
- The master license held personally by the departing owner
- Revenue tied to the local building cycle
- Concentration in one or two big accounts
- An aging service fleet due for replacement
Where these numbers come from
The multiples and median price above are transcribed from BizBuySell, Business Valuation Multiples by Industry, which aggregates real sold-business transactions (businesses sold Q3 2021 – Q2 2026). 80% of businesses in the source data set sold between $50,000 and $2,000,000 — the “main street” segment. SDE (Seller’s Discretionary Earnings) follows the IBBA standard: pre-tax profit plus one owner’s compensation and other add-backs.

Frequently asked questions
How much does a plumbing business sell for on average?
Over the period businesses sold Q3 2021 – Q2 2026, plumbing business businesses sold for a median price of $699,000 and an average of 2.61× SDE (Seller's Discretionary Earnings). Your own number depends on your earnings — for example, $265,000 of SDE at the average multiple works out to about $691,650.
Why do plumbing business businesses sell for 2.61× SDE?
Like HVAC, plumbing earns its multiple through repeat and emergency service work that doesn't depend on discretionary spending. The strongest sellers carry service agreements and a licensed team; pure new-construction plumbing, which rises and falls with the building cycle, prices lower and is harder for a buyer to underwrite.
How can I increase what my plumbing business is worth?
The multiple rewards earnings a buyer believes will survive the ownership change. For plumbing business businesses that means: recurring service and maintenance agreements; licensed plumbers who remain after the sale; a service-and-repair mix over new construction. Each one makes the earnings look more durable to a buyer and nudges the multiple up.
Is this an official plumbing business valuation?
No. This is an informational estimate built from published transaction averages, not a formal business appraisal or a broker's opinion of value. Treat it as a starting point to bring to a real conversation — run your own numbers in the calculator, then confirm with a qualified broker or appraiser.
