How Much Is a Window Cleaning Business Worth in Australia?
A window cleaning business in Australia is typically worth between 1.5 and 3 times its annual seller's discretionary earnings (SDE). For most small operations turning over $300,000 to $600,000 a year, that puts the sale price somewhere between $150,000 and $500,000. The exact number depends almost entirely on four things: contract type, customer concentration, owner dependency, and whether the rounds can be transferred to a new owner without losing half the client list.
That range is wide for a reason. A one-person operation with $400,000 in residential rounds — all of it locked in the owner's head and phone — is worth something very different from a business with the same revenue, six staff, and three-year contracts with strata management companies. Both are "window cleaning businesses." The market treats them quite differently.
This is covered in depth in Module 4 of the Playbook, which walks through how to value trades businesses across the full range of Australian industries.
What multiple do window cleaning businesses sell at in Australia?
Window cleaning businesses typically sell at 1.5 to 2.5 times SDE for owner-operated rounds, and 2 to 3 times SDE for businesses with staff, contracts, and documented systems. Very few exceed 3x unless there are long-term commercial contracts with blue-chip clients.
Seller's discretionary earnings is the relevant metric here, not EBITDA. SDE adds back the owner's salary, personal expenses run through the business, depreciation, and any one-off costs. For a small business where the owner is working in it, SDE captures the true economic return better than EBITDA does.
A rough rule of thumb: if you can document the rounds, hand them over cleanly, and show three years of stable financials, you're in the 2x to 2.5x range. If the rounds are in the owner's head and the clients don't know a sale is happening until the new person shows up with a squeegee, you're at 1.5x if you're lucky.
Residential vs commercial — how the contract type affects value
This is the single biggest driver of valuation in window cleaning, and most sellers don't fully appreciate it until they're trying to get a price.
Residential rounds are the traditional model — a route of homes serviced monthly or quarterly, billed per visit or per month. Buyers like the predictability of round work but worry (rightly) that residential clients follow the cleaner, not the business. If the owner has been cleaning the same 200 homes for eight years and those clients have his mobile number, there's meaningful risk that a chunk of them drift away when he sells.
Commercial contracts — office buildings, strata buildings, retail centres — are typically documented, invoiced to a business or body corporate, and less dependent on a personal relationship. A three-year contract with a property management company is worth considerably more than the same revenue from 200 residential clients who'd probably follow whoever cleaned their windows for the last decade.
I've seen sellers try to value their residential-only businesses at the same multiple as comparable commercial operations. Buyers with any experience will push back hard. If you're a buyer, that conversation is worth having.
What a window cleaning business's financials actually look like
Margins in window cleaning are surprisingly healthy for a service business. A well-run operation should produce SDE margins of 25 to 40 percent of revenue. An owner-operator working the rounds themselves, keeping overheads lean, can clear 40 to 50 percent.
The cost structure is relatively simple: labour (if you have staff), vehicle costs, equipment, chemicals, insurance, and whatever software you're using to manage bookings. There's no cost of goods to speak of. That simplicity is part of what makes the industry attractive — it's hard to hide losses in a business with this kind of cost structure.
For context on how EBITDA multiples apply across trades businesses, window cleaning sits at the lower end of the multiple range because of the physical, route-based nature of the work and the relationship risk with residential clients.
A $500,000-revenue business with a 30 percent SDE margin generates $150,000 in SDE. At 2x, that's a $300,000 sale price. At 2.5x, it's $375,000. The difference between those outcomes usually comes down to how well the owner can demonstrate the business runs without them.
What makes a window cleaning business worth more
The factors that push a window cleaning valuation toward the top of the range:
Documented commercial contracts. Written agreements with strata companies, commercial property managers, or corporate clients with automatic renewal provisions. These transfer with the business, don't depend on relationships, and give a buyer genuine recurring revenue.
Multiple staff who know the routes. If the owner has stepped back from the physical work and the team operates independently, the business is less vulnerable to client attrition on sale.
Route software and documented systems. Businesses running on job management software — with routes logged, recurring schedules automated, and invoicing handled digitally — are more transferable. A buyer can learn the operation without relying on knowledge that currently lives in the owner's head.
Low customer concentration. If the top 10 clients represent under 30 percent of revenue, the business is much more resilient to losing one or two during the transition. Strata and commercial businesses often have many small contracts rather than a few big ones, which is structurally better for a buyer.
Long handover period. A seller who agrees to 3 to 6 months working alongside the new owner, doing client introductions and handling the transition properly, reduces buyer risk and justifies a higher price. (Most sellers say they'll do this. Whether they actually follow through is a different story — which is why the seller handover checklist matters.)
What makes a window cleaning business worth less
Equally important to understand if you're a seller trying to price realistically, or a buyer trying to negotiate:
Owner is the relationship. If every client knows the owner by name, texts him directly, and has never dealt with anyone else from the business, that goodwill is not fully transferable. A sophisticated buyer will price that risk in.
Verbal agreements only. "I've cleaned their windows every month for 12 years and they've never complained" is not the same as a contract. Without written agreements, a buyer has no certainty that clients will stay.
Ageing equipment. Water-fed pole systems, vans, and high-reach equipment have finite lives. If the equipment is due for replacement, a buyer will factor that capital expenditure into their offer — or use it as a chip to renegotiate.
Residential-only client base. As noted above, residential rounds carry more attrition risk than commercial contracts. Not a dealbreaker, but it limits the multiple you can justify.
Cash revenue without records. Some window cleaners operate partly in cash. If the financials don't reflect actual revenue, a buyer can't lend against it, can't justify a bank loan, and won't pay a multiple for income that can't be verified. This is an area where sellers routinely overestimate what they'll get.
How buyers typically finance a window cleaning business purchase
Most window cleaning businesses in the $150,000 to $500,000 range are financed through a combination of cash deposit (20 to 30 percent), bank lending, and sometimes vendor finance.
Bank lending for service businesses like window cleaning depends on tangible assets and documented recurring revenue. A business with commercial contracts and three years of clean financials will get better lending terms than a purely residential operation. Lenders want to see that revenue is genuinely recurring and not dependent on the owner's ongoing presence.
For more on how to finance buying a small business in Australia, the key variables for window cleaning are the quality of the financials and whether contracts are documented.
Vendor finance — where the seller takes a portion of the purchase price as structured repayments over 12 to 36 months — is common in this industry. Sellers will sometimes accept a lower price in exchange for a structured payout, particularly if they're worried about getting the full amount up front from a bank-funded deal. From a buyer's perspective, vendor finance aligns the seller's incentive to support the transition, which is genuinely useful in a relationship-heavy business.

FAQ
Is window cleaning a profitable business in Australia?
Yes, for a well-run operation. SDE margins of 25 to 35 percent are typical; an owner-operator working the rounds can clear 40 percent or more. The business model is simple, overheads are manageable, and demand is consistent. Profitability drops significantly if labour costs are poorly managed or if the client base is too concentrated.
What business can I start with $100K in Australia?
With $100,000, you can buy a small owner-operated window cleaning round or launch a new operation with equipment and working capital. Buying an established round is generally lower risk than starting from scratch — you're acquiring existing clients and revenue rather than building from zero. See whether a window cleaning business is worth buying for a more detailed breakdown.
How much is a business worth with $1,000,000 in sales?
It depends on the profit margin, not the revenue. A window cleaning business turning over $1,000,000 might generate $250,000 to $350,000 in SDE. At a 2x to 2.5x multiple, that's a $500,000 to $875,000 business. Revenue alone doesn't determine value — what matters is how much of it flows through to the owner after costs.
How profitable is a cleaning business in Australia?
Commercial cleaning typically runs thinner margins than window cleaning — 10 to 20 percent net — because of higher labour intensity and more competitive pricing. Window cleaning margins are generally better. For how much a cleaning business is worth in Australia, the same multiples framework applies, but the margin starting point is usually lower.
The bottom line
A window cleaning business in Australia is worth what a buyer can verify and finance — which means the multiple you get as a seller depends almost entirely on how well you've documented the business, formalised the client relationships, and built something that doesn't fall apart the moment you hand over the keys.
Sellers who've built that kind of operation typically get 2x to 2.5x SDE. Sellers who haven't usually find out the hard way that residential rounds and a strong personal reputation don't translate into the price they were expecting.
If you're a buyer evaluating one of these businesses, the key questions are always: how dependent is this revenue on the specific person selling, and can I verify that it'll still be there in 12 months? If you can answer both confidently, you've got a deal worth looking at.
