Every spring a particular kind of operator works through Sydney’s older and wealthier suburbs. The approach is consistent enough to be a script, and it is worth recognising.
This is not about undercutting competitors. Plenty of good small operators quote cheaply and do fine work. It is about a specific pattern that produces the damage we get called to assess afterwards.
The script
We were doing a job up the road and have product left over. There is no leftover product. Chemistry is mixed to the job, and the line exists to explain an implausible price and to create urgency.
We noticed your roof from the street. Sometimes followed by a photograph of a roof in poor condition. It is frequently not your roof. Ask them to show you where on your roof it is, and to point at it from the ground.
We can start right now. Legitimate operators are booked. Immediate availability on a knock is not a lucky gap.
The price is only good today. A deadline exists to prevent you getting a second quote, which is the single action that would end the conversation.
Cash, or a deposit up front. The point of the exercise in the worst cases.
What the law already says about this
Here is the part most people do not know, and it is strong.
If someone approaches you uninvited — knocks on your door or cold-calls — and negotiates a service agreement, the Australian Consumer Law treats it as an unsolicited consumer agreement, and a set of rules applies whether or not the trader likes them.
Permitted hours. Door-to-door traders may only call between 9am and 6pm on weekdays and 9am to 5pm on Saturdays. Not Sundays, not public holidays.
They must identify themselves and state their purpose before negotiating, and must leave immediately if you ask them to. They must not approach a residence displaying a do-not-knock notice.
Ten business days to cancel. You have a cooling-off period and can cancel for any reason, verbally or in writing.
No payment and no work during the cooling-off period. This is the crucial one for exterior cleaning. A trader who signs you up at the door and starts washing that afternoon has breached it, and a trader who takes your money has too.
The penalty for those breaches is that your cancellation right extends — to three months, or to six months depending on the breach. So the operator who took cash and started immediately has handed you six months to unwind the agreement. The ACCC sets out the rules, and NSW Fair Trading handles complaints.
Worth knowing: asking for a quote at the door does not make it solicited. If the approach came from them, the protections apply.
What goes wrong technically
Separate from the money, the work itself is the lasting problem, because a doorstep job is a fast job by definition.
Roofs get pressure washed, which strips the factory coating from concrete tiles and leaves a porous surface that regrows moss faster than before, drives water under laps, and breaks tiles. Sandstone gets hit with high pressure or acid, both of which are permanent. Render gets lanced and the drummy sections come off. Fibro gets washed, which is the serious one.
None of this involves a test patch, a tap test, masking or a rainwater tank being disconnected, because all of those take time that the economics do not allow.

Where it is worst
Older housing stock with valuable, damageable materials, and suburbs with a high proportion of retirees.
Which in Sydney means sandstone country and the heritage terraces — Woollahra, Paddington, Hunters Hill, Mosman — plus the Northern Beaches and anywhere with visible roof growth after a wet winter. The visible roof is what makes a property a target, and a visibly mossy roof in a good street is effectively advertising.
The verification that takes two minutes
Ask for a business name and an ABN, and check it on the ABN Lookup register while they stand there. Registered last month, or no ABN at all, is the answer you are looking for.
Ask for a certificate of currency for public liability, emailed before any work. Check the entity name on it matches the name on the quote.
Ask what method they will use on your specific roof material, and listen for whether they distinguish between pressure washing and soft washing at all.
Ask for a local address and two recent local references. Then say you will get a second quote and call them back. The reaction to that sentence tells you everything — a real operator says fine, and a doorstep operator starts negotiating.

If an older relative has already signed
Act quickly, but know the position is stronger than it feels.
Put the cancellation in writing and keep a copy. If payment was taken or work started during the cooling-off period, the cancellation right is extended well beyond ten business days. Photograph everything, including any damage. Contact NSW Fair Trading, and the bank if a card payment was involved.
The consumer guarantees of due care and skill apply regardless of what was signed, and no clause in a doorstep contract removes them.
And the honest caveat
Not everyone who knocks is a problem. Small local operators sometimes door-knock a street legitimately, and some of them do good work.
The distinction is not the knock. It is the urgency, the cash, the immediate start and the refusal to let you get a second quote. A trader who is happy to leave a written quote and wait a week is behaving normally. More: how to compare quotes.
