## 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](https://searchspheresource.com/glossary/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](https://searchspheresource.com/glossary/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](https://searchspheresource.com/glossary/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:

## Financeability Notes

Equipment is cheap and used markets are liquid, so collateral is thin and [7(a)](https://searchspheresource.com/glossary/sba-7a) 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](https://searchspheresource.com/glossary/run-rate). The small residential end trades on [seller notes](https://searchspheresource.com/glossary/seller-note) below bank appetite, which is most of the listings a search surfaces.

## What this guide verified

- 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. (Census County Business Patterns, services to buildings and dwellings (2023): https://www.census.gov/programs-surveys/cbp.html)
- 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. (BLS Occupational Employment and Wage Statistics, janitors and cleaners (2025): https://www.bls.gov/oes/)
- 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. (IBBA and M&A Source, Market Pulse quarterly highlights: https://www.ibba.org/resource-center/industry-research/)

## Terms of the trade

- **Soft washing**: Low-pressure chemical cleaning for surfaces that high pressure would destroy, priced higher. It is the difference between a business that cleans concrete and one a homeowner calls for a roof, and roofs price several times higher per hour on site. It needs chemical knowledge, different equipment and, in some states, a pesticide applicator license for the algaecides involved. Ask what share of revenue comes from soft-wash work, what licenses the crew holds, and whether those licenses belong to a person who is leaving.
- **Fleet washing**: Contracted washing of a company's trucks on a standing schedule, billed monthly. Fleet accounts wash the same trucks weekly or monthly on contracted rates, which converts a seasonal one-off trade into schedulable, year-round revenue. Sale guidance for the trade treats recurring commercial share as the central multiple lever, and fleet work is its steadiest form. A fleet book also concentrates: count how much of it sits with the top accounts before pricing it, because one lost yard can be a season's margin.
- **Crew-day**: One crew's full day of sellable work, the unit pressure washing prices and plans by. Pricing a pressure washing business starts with what one crew produces in a full day and how many crew-days a season actually sells. Revenue per crew-day, by month, shows the productivity and the seasonality in one line, and it is the number that separates a contract operator from a weekend competitor. A book that cannot state it is quoting jobs by the owner's eye, which is a system a buyer must build, not one they are buying.
- **Wash water capture**: Catching and disposing of the runoff a job produces, which many commercial sites require. Stormwater rules make the wash water a regulated discharge on a lot of commercial work, so a contractor without the recovery equipment and a disposal arrangement is quietly limited to residential jobs and to clients who have not asked yet. That is a ceiling on the book rather than a fine waiting to happen. Ask what recovery gear is owned, where the water goes, and which current customers require documentation of it.
- **Home improvement line**: Where washing stops and home improvement starts, which is what turns the whole rulebook on. Three of the strictest home improvement statutes define the trade with verbs that alter a structure, and none of them reaches cleaning, so washing alone triggers no registration, no statutory contract, and no guaranty fund payment. The moment the same crew seals a deck, paints, or treats a roof, all of it switches on. In Massachusetts that means a registration certificate the statute says is not transferable, and a fund payment scaled by headcount from one hundred dollars under four employees to five hundred above thirty. It also means a named individual personally on the hook alongside the company. Ask exactly which services the crews sold last year, because the answer decides which business is being bought.
- **Door-knock sale notice**: A job the crew sold at the door carries the full cancellation notice and no exclusion at all. Every exclusion in this area opens with the buyer having initiated the contact, so a sale the crew solicited forecloses all of them at once. The rule switches on at twenty five dollars where the sale is made at a residence and a hundred and thirty dollars everywhere else it reaches, and it names the customer's workplace as one of those places. What is owed is the whole apparatus: three business days, the boldface statement beside the signature line, and the detachable notice of cancellation in duplicate. North Carolina makes a willful failure to hand over the paperwork a Class 3 misdemeanor, and adds a second one for failing to refund within ten business days. Where no form was given an oral cancellation is good, which removes the shelter of nothing having arrived in writing. Ask what share of last year's work was sold at the door, and read the door script beside the ticket.
- **Shingle warranty exclusion**: The clause that voids a roof warranty if the roof is cleaned with pressure. Roof cleaning is the highest-priced work this trade sells to homeowners, and asphalt shingle manufacturers exclude damage caused by pressure washing from their warranties, which is why the trade moved to low-pressure chemical washing for roofs. A crew that pressure washes a roof can void a warranty worth more than the job, and the homeowner finds out years later when a claim is denied. Ask which method the book's roof work uses, whether the quotes say so in writing, and whether anybody has ever had a claim come back.
- **Discharge point**: The place captured wash water may legally go, which is never a storm drain. Wash water capture is the equipment and this is the recurring cost behind it. Federal law requires a municipal storm sewer permit to effectively prohibit non-stormwater discharges, and any discharge to a storm sewer not composed entirely of storm water is an illicit discharge, which is why the local ordinance a crew actually meets exists at all. The sanitary sewer is the alternative and it is not automatic. One large authority allows discharge only through a private connection at the customer's own facility, at a rate that will not back the system up, and forbids it at any manhole in the public right of way. The federal pretreatment rule allows hauled waste only at a point the treatment works itself designates. So route density is disposal density too. Ask whether the seller's own yard has a permitted discharge point, because a business without one is paying a hauler forever.
