How do you value a plumbing company for sale?
Valuing a plumbing company is a two-step exercise. First, normalize earnings: start from profit and add back the owner's salary, perks, and one-time or non-business expenses to get SDE (for smaller shops) or EBITDA (for larger, managed companies). Second, apply a market multiple. Plumbing companies typically trade at about 3.5x-6.5x EBITDA, or 2.0x-4.0x SDE for owner-operated businesses.
Where you land in the range is driven by the quality of the earnings. Recurring service and maintenance revenue is worth more than one-off new-construction jobs; a strong service mix, repeat residential and commercial customers, licensed technicians who will stay, and a business that runs without the owner all argue for the top of the range. Heavy reliance on a few large customers, thin margins, or an owner who is the lead technician pull the multiple down.
Buyer type sets the ceiling. An individual buyer usually pays 2x-3x SDE with SBA financing; a private-equity platform consolidating the trades pays 4x-8x EBITDA, commonly 60%-80% cash at close with the balance as equity rollover or a seller note. DealSeam is not a traditional business broker; where there's a fit, it introduces owners to qualified buyers, and the buyer pays the success fee.
