How Much Is a Pressure Washing Business Worth in Australia?
A pressure washing business in Australia is worth between 1.5 and 2.5 times its annual Seller's Discretionary Earnings (SDE). The range is wide because pressure washing spans two very different business types: residential round operators who clean driveways and decking on a call-out basis, and commercial operators with strata, council, and industrial facility contracts that generate predictable recurring revenue. A business sitting firmly in the second category is worth considerably more than one in the first — even if the revenue numbers look similar on the surface.
This guide covers how buyers actually value pressure washing businesses, what drives multiples up or down, and what the typical deal looks like in the Australian market.
What valuation method applies to pressure washing businesses
For pressure washing businesses generating under $1 million in annual profit, the right measure is Seller's Discretionary Earnings — the total economic benefit flowing to a working owner-operator. This includes the owner's wage (or what they draw from the business), the business's operating profit, and any personal or one-off expenses the business has been carrying that a new owner wouldn't.
A rule of thumb: a well-run pressure washing business with good commercial accounts and consistent earnings should sell for 2 to 2.5 times annual SDE. An owner-operated residential round with no contracts and no staff should sell for 1.5 times SDE, and only if the client list is documented and the goodwill is transferable.
Larger operations — say, above $300,000 in EBITDA, with multiple crews and a diversified commercial client base — can attract EBITDA-based valuations from trade buyers and small PE firms. In that range, you'd typically see 3 to 4 times EBITDA, though these deals are less common and take longer to find. Most pressure washing businesses in Australia sit well below that threshold.

What pressure washing businesses typically earn in Australia
Margins in this industry are genuinely good — if you're running it properly. A one-person owner-operator doing a mix of residential and small commercial work should be clearing $70,000 to $120,000 in SDE. A small operation with one employed team member and a solid commercial book can reach $150,000 to $250,000. Above that, you're usually looking at a multi-crew business with real systems in place.
Revenue-wise, most small pressure washing businesses in Australia turn over between $150,000 and $600,000 per year. EBITDA margins tend to land in the 25 to 40 percent range for operations that aren't carrying excessive equipment finance or over-staffed. The high margin is one of the reasons these businesses are attractive — low labour input relative to revenue, minimal materials cost, and pricing that holds in most economic conditions (dirty things stay dirty regardless of interest rates).
The problem with relying on revenue multiples: equipment financing, lease commitments, and owner drawings can make two businesses with the same revenue look very different at the profit level. Always normalise to SDE or EBITDA before you apply a multiple.
Commercial versus residential — the most important valuation driver
The single biggest factor in what a pressure washing business is worth is whether its revenue comes from commercial clients or residential ones.
Commercial pressure washing clients — strata managers, industrial facility managers, councils, food manufacturing sites, shopping centres — typically book on a set schedule. A strata building might require pressure washing of common areas quarterly. An industrial site might need regular concrete degreasing and graffiti removal. A council might have a term contract for maintenance of public infrastructure. These clients generate contracted, recurring income that a buyer can model with confidence.
Residential clients are the opposite. They call when the driveway looks bad enough. They cancel when it rains (and it rains a lot in south-east Queensland). They switch providers if someone leaflet-drops their street at the right time. The margins are reasonable but the predictability is low, which is exactly the thing that makes goodwill transferable — or not.
One rule of thumb I'd apply to any pressure washing acquisition: if the business can't demonstrate at least 35 percent of revenue from clients booked on a regular schedule, you're buying a job that happens to come with equipment. The multiple should reflect that.
I spoke to a business broker in Melbourne last year about a pressure washing business that had been on the market for four months without a serious offer. The numbers looked fine — $90,000 SDE, reasonable equipment, decent Google reviews. The problem was that 80 percent of the clients were residential one-offs. The seller was asking 2.3 times SDE. Buyers kept looking at the client list and doing the maths on retention risk, and the price didn't hold up. It eventually sold at 1.4 times.
Equipment value and what it adds (and doesn't add) to the sale price
Pressure washing businesses are more asset-heavy than something like a lawn mowing or pest control operation. A quality hot-water trailer rig — the kind used for commercial concrete cleaning, graffiti removal, or industrial degreasing — can be worth $15,000 to $40,000 new. Cold water units used for residential work are worth less: $2,000 to $8,000 for a decent setup.
In a business sale, equipment value matters, but it doesn't simply add to a multiple-based valuation in the way buyers sometimes expect. The equipment is necessary for the business to function — it's not a separate premium. What equipment quality does affect is buyer confidence and the amount of capex required post-acquisition.
A business where all equipment is owned outright, well-maintained, and within the first half of its useful life commands a higher multiple than one where the gear is financed (so it comes with monthly obligations) or aging (so the buyer faces an early replacement bill). I've seen buyers renegotiate the purchase price down by $30,000 to $50,000 after discovering the key hot-water unit was three years from needing replacement — something that should have been flagged up front but wasn't.
In an asset sale structure, the equipment is listed separately with agreed values. In a goodwill-plus-plant sale — which is the more common structure for these businesses in Australia — the equipment is bundled. Either way, ask for a current condition report and any recent service history before you commit to a price.

Owner dependency — the number that drives discounts
Pressure washing businesses are highly susceptible to owner dependency, and buyers tend to discount aggressively for it.
The owner is usually the face of the business, the quality control, the safety supervisor, and often the person who personally manages the commercial client relationships. When that person leaves, some of those relationships go with them. The question is how many.
For commercial clients under contract, the risk is lower — the contract runs with the business entity, not the individual. For residential clients and informal commercial arrangements, the risk is higher. A commercial client who books because they like the owner and trust his crew will behave very differently to a strata manager whose building is covered by a written agreement.
This is where Seller's Discretionary Earnings can be misleading if you take it at face value. A business generating $150,000 in SDE might look like a 2x purchase at $300,000 — but if you honestly assess that 40 percent of the client base is at retention risk, you're looking at a business worth $180,000 to $200,000 at best, after you've discounted for the likely revenue loss in year one.
Buyers who want a realistic view of what they're actually inheriting should work through the Owner Dependency Scorecard.
This is covered as part of Module 4 in the Playbook, where valuation and risk assessment work together rather than as separate steps.
What a premium pressure washing business looks like
For context, here's what a pressure washing business that commands 2.5 times SDE actually looks like in practice:
- Minimum 40 percent of revenue from commercial clients booked on a schedule
- Written agreements with at least some commercial clients (even informal LOA-style arrangements beat verbal)
- One or two employed or subcontracted operators who can complete work without the owner on-site
- Equipment owned outright, maintained, within useful life
- Job management software in use — client history, access details, job notes documented
- Google rating of 4.5 or above with at least 30 reviews
- Revenue stable or growing over the past three years
- Owner has been running the business for at least five years (shorter tenure increases goodwill transferability risk)
A business that ticks all of these can reasonably ask for 2.2 to 2.5 times SDE and find motivated buyers.
A business with none of these ticking — residential only, owner does everything, nothing documented — should expect 1.2 to 1.5 times SDE, and finding a buyer who isn't just acquiring the equipment may take a while. (Not impossible. Just harder.)

Typical deal sizes for pressure washing businesses in Australia
At the small end — a one-person residential round generating $60,000 to $80,000 in SDE — you're looking at deals in the $80,000 to $150,000 range, usually structured as asset sales with a short handover period.
In the mid-range — $100,000 to $200,000 in SDE with some commercial accounts and one or two staff — deals typically land between $200,000 and $400,000. These are the most common transactions in the Australian market and attract the most interest from buyers with $200,000 to $500,000 to invest.
At the upper end — $250,000 or more in EBITDA, multi-crew, diversified commercial base — you're in a different market. These businesses can attract $600,000 to $900,000, occasionally more, but they're rare and take time to locate. Brokers see them occasionally; private equity sees them even less often because the deal sizes are below most firms' minimum.

Frequently asked questions
How profitable is a pressure washing business in Australia?
A well-run pressure washing business generates EBITDA margins of 25 to 40 percent. An owner-operator typically clears $70,000 to $120,000 per year. Operations with employed staff and commercial accounts can reach $200,000 or more in annual profit.
Is pressure washing a good business to buy?
It can be. The margin structure is attractive, entry costs are low, and demand is consistent. The risks are owner dependency, low commercial contract conversion, and equipment that ages faster than some buyers account for. Commercial-heavy operations with documented clients make the most defensible acquisitions.
What multiple do pressure washing businesses sell for in Australia?
Small owner-operated businesses typically sell for 1.5 to 2 times annual SDE. Operations with commercial accounts and employed staff can reach 2 to 2.5 times. Larger operations above $300,000 in EBITDA may attract 3 to 4 times EBITDA from trade buyers.
Why do some pressure washing businesses fail after acquisition?
Client retention is the most common reason. Buyers pay for goodwill that they can't hold — particularly in residential-heavy operations where clients were loyal to the previous owner rather than the business. The second most common reason is equipment failure in year one that wasn't identified during due diligence.
How do I verify the revenue of a pressure washing business I'm buying?
Ask for three years of bank statements, BAS lodgements, and tax returns. Cross-reference the revenue against the client list — each commercial client should have a corresponding invoice history. For residential work, check the job management software records or, if the business uses none, ask for a full client list with last service date and average spend.
