Buying a Pressure Washing Business
Crew-Days Against the Season
Pressure washing has the lowest equipment barrier in the exterior-service lane, which floods the bottom of the trade with weekend operators and makes the contracted commercial book the version worth an acquisition at this site's floor. The economics are crew-days sold against fuel, water, and insurance, and the business is either a marketing machine reselling one-off driveways every spring or a contract operator washing the same fleet yards, shopping centers, and restaurant chains on schedule. The two share equipment and nothing else.
What Pressure Washing Businesses Trade For
No publisher of sold data has a pressure washing page, so this reads the publisher's sold cleaning and janitorial class, half of transactions between 1.57x and 2.66x SDE, the same class this trade's nearest siblings read. That substitution is ours: the class names window, gutter, solar panel and industrial cleaning among its specialized trades and never names pressure washing. The route class this guide read before it was worse, since that page defines its own scope as pool service, ATM and delivery routes, a book of standing accounts rather than a service book. Trade buyer guides put commercial operators with recurring contract books in a higher lane and note that two businesses with identical earnings can transact far apart on mix alone.
The Contract-Mix Lever
The single valuation driver the trade's sale guidance names is recurring commercial share: HOA grounds, retail centers, restaurant chains, gas stations, and fleet washing on standing schedules. Recurring work smooths the season, runs without the owner selling every job, and is what a lender and a buyer can both underwrite. In diligence, build the revenue bridge by contract, check each for remaining term and assignment, and treat the residential remainder as marketing yield rather than a book. Washing pre-1978 housing exteriors for pay is renovation under the federal lead rule past twenty square feet: a certified firm, a certified renovator, and containment that holds the wastewater. Firm certification does not come with the assets.
The Season and the Crew
Revenue concentrates in the warm months across most of the country, so the working-capital question is what the winter costs and what commercial contracts still bill through it. The second question is who runs the crews: a book where the owner quotes, schedules, and leads every job is a job with equipment. Read a full year of weekly revenue for the seasonal spread, confirm crew leads are W-2 and paid to stay, and check whether quoting is priced by rule or by the owner's eye. Ask early where the water goes. Anything entering a storm drain that is not rain is an illicit discharge under federal rules, and detergent is the switch: a plain pavement wash is allowed on a construction site and the same wash with soap is not.
What to Verify in Diligence
The record to assemble before the offer holds:
- Revenue split by recurring commercial contract, repeat residential, and one-off
- Each commercial contract read for term, pricing, and assignment
- A full year of weekly revenue mapped for seasonality
- Crew leads and their pay confirmed against market
- Equipment condition, water permits or reclaim rules where they apply, and insurance claims history
- Customer concentration measured across the top five accounts
Financeability Notes
Equipment is cheap and used markets are liquid, so collateral is thin and 7(a) underwriting rides cash flow, seasonality, and the guaranty. A contracted commercial book underwrites like a service company; a residential one-off book underwrites like a marketing spend with weather risk, and lenders price the difference. Expect a working-capital line sized to the winter months rather than the summer's run rate. The small residential end trades on seller notes below bank appetite, which is most of the listings a search surfaces.

What the Data Says
Exterior cleaning has no census class of its own, and the containing class, other services to buildings and dwellings, counts 18,069 employer establishments as of 2023. That classification gap is worth knowing, because it means no federal series will ever confirm a broker's claim about this specific trade's size.

The nearest federal occupation to an exterior-cleaning crew, janitors and cleaners, employs 2,209,760 people at a $36,840 median in 2025. That wage line is the honest anchor for crew economics in a trade where the equipment is cheap and the margin lives in route density and commercial contracts.

In the quarterly Market Pulse survey run by the IBBA and M&A Source, businesses selling between $500k and $1M carried a 2.8x SDE multiple, and that band has printed 2.8x in nearly every quarter published since 2023. It is the band a contract-led pressure washing book prices against.

What It Costs to Replace the Owner
The multiples above are quoted on SDE, which adds the owner's pay back into earnings, so they hold only if you do the owner's job. Hire someone instead and the going rate for the role comes back out. For this trade that is usually the supervisor over cleaning crews, paid a median of $49,100 a year nationally. Subtract it from SDE before applying any multiple, because at a 3x multiple that wage also takes about $147,300 off what the business is worth to you.
