What a water damage job actually looks like, hour by hour
A callout from arrival to sign-off — what techs actually do, what the gear is for, and how cleaners get into this work in Australia.

Most people picture a flood job as blokes with a wet vac. That's about twenty minutes of it.
Water damage restoration is one of the few trades in Australia you can walk into from cleaning without a licence or an apprenticeship, and one of the few where knowing the theory changes your pay rather than just your paperwork. Here's what the day actually involves.
The call comes in
Usually it's an insurer or a facilities manager, and usually it's not convenient. Burst flexi hose overnight. Storm through a roof. A washing machine that let go while everyone was at work.
The first thing a tech does on arrival isn't touch anything. It's stand still and look. Water jobs hurt people in predictable ways, and the biggest one isn't what you'd guess. It's not the sewage and it's not the electricity. It's the floor. Slips, trips and falls put more restoration techs in hospital than anything else on site.
Second thing: kill the power. Not "check whether the lights work." Isolate it at the board. There's wiring above every ceiling you're about to pull down.
Working out what you're dealing with
Two questions decide the whole job, and getting either wrong wrecks it.
How dirty is the water? Clean water from a burst supply line is one thing. Water that's come up out of a sewer is another entirely, and so is clean water that's been sitting in a filthy subfloor for three days. Contamination isn't fixed — it degrades with time and temperature. What was clean on Monday morning isn't clean by Wednesday.
That call changes your PPE, what comes out of the building, and whether the family can sleep there tonight.
How much material is wet? Not how much water. How much material. A tiled bathroom holds almost nothing. A carpeted lounge with wet plaster halfway up the walls holds a lot. Concrete and hardwood hold water for weeks and barely give it back.
That call decides how much gear goes in and how long you're coming back.
Making it safe
Sagging ceilings come down, and they come down early. Wet plasterboard loses strength and holds water, and linings can collapse mid-dry with someone underneath.
The technique is specific. Isolate power. Bucket ready. Drill a small weep hole at the lowest point of the sag and let it drain. Then decide whether the sheet goes. Plasterboard that's still flat and sound can often be dried and saved.
If there's a second layer under the flooring you're lifting, assume that layer or its glue contains asbestos until someone qualified says otherwise. No brooms, no compressed air, no pressure washing.
Setting up the dry

Here's where most people's mental model of the job is wrong.
Air movers don't dry buildings. They speed up evaporation off surfaces. If you run them without dehumidification or ventilation, all that water goes into the room air, and then materials that were dry to start with absorb it. You haven't dried the house. You've moved the water into the walls.
Moisture goes where it's drier, always. Warming a wet material pushes moisture out of it faster. Pulling humidity out of the air gives it somewhere to go. Airflow is one part of a system, not the system.
That's the bit that separates a labourer from a technician, and it's why the pay is different.
Proving it
The job isn't done when it looks dry. It's done when the numbers say so and you can show them.
Readings go in daily, minimum. Temperature, relative humidity, dew point, moisture content in the affected materials and in unaffected material for comparison. Where you took each reading. Outside, inside, dehumidifier output, unaffected area.
If it's not drying, you change the plan. If you can't show it dried, the insurer can decline it — and the tech who took no photos on day one is the one wearing that.
Getting into it
The entry gate in Australia is smaller than most people think. Driver's licence, construction White Card, police check. That's the list on most restoration ads. Plenty say experience preferred but not required, with training provided.
The certification is closer than people assume too. The IICRC Water Damage Restoration Technician course runs three days in Australia, around $895 plus the exam fee, and has no prerequisites. You don't need a trade background. You don't need to already be employed in restoration.
It also opens the next doors. Mould remediation certification requires WRT first. So does most of the path upward.
If you're cleaning now and wondering what the next rung looks like, this is usually it.
