How much can I sell my plumbing business for in Illinois?

SBA and owner-operator lenders

SBA buyers want an Illinois-licensed plumber in the deal — as buyer, key employee, or a documented hire before closing. Underwriters will ask how permits get pulled after the seller’s license leaves the wall. They will also test customer concentration if one general contractor is a third of revenue.

Private equity and platforms

Home-services platforms buy plumbing when the route density is real and the commercial mix does not depend on one construction GC. They will normalize owner trucks, family payroll, and one-time new-construction spikes. If your SDE is mostly remodel mark-up from a housing boom year, expect a lower multiple or a heavy earnout.

Owner-operators next door

The most common closer is still another plumber — a competitor who wants your north-side route, or a licensed tech whose spouse can run the office. They pay for call volume they can keep. They discount names they know will follow the seller to a ‘consulting’ side hustle.

We do not spray your identity across listing sites to ‘test the market.’ Plumbing is a small community in every Illinois county. Confidential outreach beats a public listing that tells every helper the shop is for sale.

Illinois plumbing licenses attach to people. The asset sale does not move the seller’s license onto the buyer. If the buyer is not already licensed, the deal needs a transition plan that a lender and the municipality will accept. Chicago and many suburbs also require contractor registration that must be updated, not wished through.

Bulk Sales procedures can apply to the equipment and inventory transfer. Landlord consent is often slower than buyer enthusiasm — especially in industrial parks where the landlord likes the current tenant and has not thought about assignment. Put the lease in the data room before the LOI, not after.

Drain-camera footage and water-heater serial lists look like diligence theater until a buyer asks who owns the customer relationship on a Saturday night. If the answer is still your cell phone, the multiple will say so. A dispatcher who already books the board is worth more than a new camera you bought in December to save tax.

Municipalities along the Fox River, the I-55 corridor, and the city do not share one permit culture. A buyer who is licensed in one village still has to land the others. We put that map in the file before an LOI pretends the close is forty-five days. SBA underwriters will ask the same question in plainer English.

Competitors who already run the next township are often the real buyers. They are also the people most able to use a customer list if the deal dies. Stage the file. NDA first. See the competitor-sale page if that is your likely path, and the fees page if you are still deciding whether representation is worth a success fee.

Educational only — not legal or tax advice. Confirm Bulk Sales, Secretary of State filings, license transfers, and lease assignment with counsel and a CPA. We work on a success fee with no upfront listing fee.

A plumbing company in Illinois is underwritten as licensed labor plus a call book, not as a row of branded vans. The first question is how many Illinois-licensed plumbers stay after closing, and whether the buyer can pull permits the following Monday. A Schaumburg shop with three licensed plumbers and a dispatcher is an enterprise. A one-license owner who still crawls every crawlspace is a job with trucks attached. SBA 7(a) lenders treat that difference as credit risk, not as color.

Neighboring plumbers remain the most common closer in many Illinois counties. They already know your north-side route and they will discount names they expect to follow the seller. Platforms buy density and commercial mix that does not hang on one general contractor. New-construction mark-up from a single housing year is the first number they normalize. If that spike is your SDE, expect an earnout conversation, not a full multiple on last year’s tax return.

We will not invent a house plumbing multiple on this page. We recast seller’s discretionary earnings, then have a planning conversation against risk: license coverage, residential versus commercial mix, and contract quality. Market-wide, BizBuySell’s Q2 2026 Insight Report showed 2.7× cash flow and a $349,250 median sale — useful context, not a plumbing appraisal. Start that conversation at /contact.

Start with tax-return profit, then add only documented, transferable owner benefits. A replacement licensed plumber’s market wage is the honest charge against owner production. One-time camera replacements and a flood-year overtime spike need footnotes, not automatic add-backs. Family payroll that does not answer the phone gets added back only when the work truly disappears. Buyers will test every line.

Written drain and water-heater programs support earnings quality. A stack of invoices from one GC does the opposite. Specialty tools that are leased should not appear as if they were owned assets on top of a cash-flow multiple. Fleet condition matters, but a new transit van is not a second check. Separate the operating company from a parts-and-truck liquidation so you do not argue with yourself in diligence.

The IBBA glossary definition of seller’s discretionary earnings is the language we use with buyers. We will not publish a house plumbing multiple we do not stand behind on this page. If you want a range that survives a quality-of-earnings review, bring three years of returns and the license list. The IRS selling-a-business page is the federal starting point for your CPA, not a substitute for one.
