The short answer: construction businesses sell for an average of 2.56× SDE across 408 reported transactions, with heavy construction averaging 2.98×, and appraiser ranges running 2.16–2.85× SDE. In dollars: roughly $640,000 for a contractor producing $250,000 of SDE. The two things that make construction different from every other purchase here: the backlog (signed future work is part of what you buy) and work-in-progress accounting, where more small-contractor fictions live than anywhere else.
Why construction deals attract operators
Construction rewards buyers who can actually run projects: the businesses are plentiful (the largest deal sample of any vertical in this library), retiring founders outnumber successors, and a contractor with recurring commercial relationships and a real estimator is a system, not a job. The cyclicality is the honest trade-off: backlog can evaporate in a downturn, which is why the market prices most contractors below the service-business multiples, and why the quality of the backlog matters more than its size.
What you are really buying, in order: the signed backlog and the margin actually left in it, the estimator and project managers who produce the next backlog, the license and bonding capacity that let the company bid, and the relationships that invite it to bid at all.
What construction businesses sell for
| Measure | Figure | Notes |
|---|---|---|
| SDE multiple, general | 2.56× average | Across 408 reported construction transactions |
| SDE multiple, heavy construction | 2.98× average | 65 reported transactions |
| Appraiser SDE range | 2.16–2.85× | Peak Business Valuation, $1–5M revenue cohort |
| Revenue multiple | 0.60–0.70× | General to heavy, same datasets |
| Worked example | $250K SDE → ~$640,000 | At the general average |
| Pushes the price up | Pulls it down |
|---|---|
| Signed backlog with verified margin remaining | Backlog booked at margins that will not materialize |
| Repeat commercial and municipal relationships | One developer feeding the pipeline |
| An estimator and PMs who are not the owner | The owner as the only estimator and closer |
| Clean WIP schedules tying to the financials | Billings ahead of costs with no schedule to prove it |
| Transferable license and bonding capacity | A license and bond line that die with the seller |
| Business size | Implied price | Note |
|---|---|---|
| $1M revenue | ~$600,000 | Owner-led crew work |
| $3M revenue | ~$1.8M | Estimator on staff; the classic first acquisition |
| $8M revenue | ~$4.8M | Bonded commercial work; EBITDA pricing |
Illustrative sizes at the dataset average; backlog quality moves a specific contractor far off these marks in both directions.
The diligence that makes or breaks a construction deal
| What to verify | The question it answers | Where it shows up |
|---|---|---|
| WIP schedule | Are stated profits real, or borrowed from unfinished jobs? | WIP tied to contracts, billings, and costs, job by job |
| Backlog contracts | What work is actually signed, at what margin? | Executed contracts and change orders, not the pipeline list |
| License and bonding transfer | Can the company keep bidding after closing? | State board rules; surety relationship |
| Estimator and PM retention | Who wins and runs the next job? | Org chart, comp, and non-solicits |
| Warranty and defect exposure | What finished jobs can come back? | Warranty terms, claim history, insurance |
The schedule that decides construction deals
Work-in-progress. Overbilled jobs book profit today that the remaining work will consume tomorrow; underbilled jobs hide profit the seller has not collected. If the WIP schedule does not tie to the contracts and the financials job by job, the earnings you are pricing are a guess, and usually the seller's guess.
Licensing and bonding: the gates on the business
Contractor licensing is state-law territory, and like HVAC and plumbing, the company typically needs a qualifying license holder, who may currently be the seller. Bonding is the second gate: surety capacity is a relationship underwritten on the company's financials and the people running it, so introduce yourself to the surety early. Losing the qualifier or the bond line after closing stops the bidding engine, which is the business.
How a typical construction purchase is financed
| Source | Amount | % of price |
|---|---|---|
| SBA 7(a) loan | $900,000 | 90% |
| Equity injection (total) | $100,000 | 10% |
| of which: standby seller note can cover | up to $50,000 | up to 5% |
| of which: your cash portion | as low as ~$50,000 | ~5% |
Working capital deserves priority in the structure, because construction pays slowly and retainage holds part of every invoice; the mechanics are in the working-capital guide and the financing stack.

Frequently asked questions
Construction businesses sell for an average of 2.56 times SDE across 408 reported transactions, with heavy construction averaging 2.98 times and appraiser ranges at 2.16 to 2.85 times. A contractor producing $250,000 of SDE prices around $640,000 at the general average.
The work-in-progress schedule shows each unfinished job's contract value, billings, and costs. Overbilled jobs book profit the remaining work will consume; underbilled jobs hide it. If the WIP does not tie to the financials job by job, the stated earnings are unreliable.
Signed contracts generally convey with the company, and they are part of what you pay for, at the margin actually remaining in them. Verify executed contracts and change orders rather than the pipeline list, and check each contract's assignment terms in an asset sale.
The company needs a qualifying license holder, who is often the seller, and state rules govern how that transfers. Bonding capacity is the second gate: the surety relationship is underwritten on the company and its people, so engage the surety before closing.
Yes, with the standard 10% equity injection, about $100,000 on a $1M contractor, and up to half as a standby seller note. Prioritize working capital in the structure, because construction pays slowly and retainage holds part of every invoice.
