Flood Damage Restoration in Wollongong and the Illawarra
Flooded home or business? We’re Wollongong based, we answer the phone 24/7, and we start extracting before mould gets a hold.
What To Do Right Now
Floodwater is not the same as water from a burst pipe. It has run across ground, roads and drains before it reached you, so treat it as contaminated from the first minute.
Stay out of the water if you can
Don’t wade through it, and keep kids and pets well clear. If you’ve had contact with it, wash properly with soap and clean water.
Do not touch anything electrical
Not switches, not powerpoints, not appliances that have been wet. If water has been anywhere near the switchboard or wiring, leave the power off and get an electrician before anyone turns anything back on.
Photograph everything before you move it
Wide shots of each room, close shots of damage, and get the high-water mark on the walls in frame. Then photograph outside: where the water came from, which direction it flowed, how deep it got. That last part matters more than most people realise, and here’s why.
Note where the water came from
Creek or river over its banks, water sheeting down off the escarpment, or the street drain backing up? Your insurer will investigate this, and it can decide which part of your policy responds. Write down what you saw and when, while it’s fresh.
Don’t start pulling things out yet
Once you’ve photographed it, wet carpet and soft furnishings need handling carefully rather than dragged through the house. Call us and we’ll tell you what’s worth saving before anything goes in a skip.
FREE INSPECTION, NO OBLIGATION
We will call you back personally to arrange a time.
Trusted Flood Damage Restoration Services
The water goes down faster than people expect. What it leaves behind is the problem: saturated carpet and underlay, plasterboard wicking moisture up the walls, silt and contamination through everything it touched, and a smell that tells you something is already growing.
Then there’s the part you can’t see. Water sits in wall cavities, under floorboards and in insulation long after the floors look dry, and in the Illawarra’s humidity it doesn’t leave on its own. That’s where a flood becomes a mould problem, usually within a couple of days.
The team at Wollongong Mould Cleaning & Removal have been doing water damage and mould work across the Illawarra for 15 years. Being local matters here, because when the escarpment dumps moisture on us there are a lot of houses needing help at once and the crews driving down from Sydney arrive last.
Does this sound familiar?
- Water through the ground floor of your home or business after heavy rain
- A creek or stormwater drain has come up and into the building
- Water came down off the escarpment and through the property
- The water's gone but the carpet, walls and floors are saturated
- Silt, mud or debris left through the place
- You need it documented properly for an insurance claim
- It happened days ago and now there's a musty smell
Call us and we’ll talk you through it on the phone, then get someone out.
Flood, Storm or Runoff? The Answer Decides Your Claim
This catches more people than anything else, and in the Illawarra it often works in your favour rather than against you. So it’s worth understanding before you speak to your insurer.
Australia has a legislated standard definition of flood, brought in after the 2010 and 2011 floods. It means the covering of normally dry land by water that has escaped from a normally confined watercourse, lake, reservoir, canal or dam. In plain terms, a creek or river over its banks.
Stormwater and rainfall runoff is a different category: high intensity, short duration rain producing localised flooding, which is what most people call flash flooding. Most policies cover that risk, and they cover it whether or not you took flood cover.
That distinction matters enormously here, because Wollongong’s flooding is overwhelmingly the second kind. Intense rain on the escarpment, water coming downhill fast, drains overwhelmed, and it’s through your house within the hour. So if you declined flood cover to keep the premium down and you’re now assuming you have nothing, don’t assume that. The Insurance Council of Australia makes the point that even where a policy excludes flood, storm or rainwater cover may still respond. Some insurers do decline runoff where flood cover was refused, so it comes down to your wording, but it’s very much worth checking rather than writing it off.
Insurers investigate the source to work out which applies. They look at rainfall records, creek levels and drainage, the direction the water travelled, and how high it would have reached on its own. Which is exactly why your photos of where the water came from, taken on day one, are worth more than anything you tell an assessor from memory three weeks later.
If yours was rain coming in through a damaged roof or broken window rather than water across the ground, that’s storm damage restoration. If it was a pipe or flexi hose inside the house, that’s burst pipe water damage, and it’s treated differently again.
This is general information rather than advice on your policy. Read your product disclosure statement and talk to your insurer.
How We Restore a Flooded Property
We make the site safe first
Power, structural safety and contamination. Nothing starts until we know the building is safe to work in and we’re set up to handle contaminated water properly.
We extract the water and remove the contaminated material
Submersible pumps and extraction units for the standing water, then the materials that can’t be saved come out. More on why below, because this is the part that surprises people.
We clean and sanitise what stays
Structural surfaces get cleaned and treated with antimicrobial products, because floodwater leaves more behind than moisture.
We map the moisture, including what you can’t see
Moisture meters and thermal imaging through wall cavities, under floors and into the subfloor. Floodwater travels much further than the waterline suggests, and the readings tell us where.
We dry the structure properly and monitor it
Commercial dehumidifiers and air movers, positioned for how your building is built and monitored with daily readings until the materials are actually dry. The detail is on our dehumidification and structural drying page.
We document all of it for your insurer
Photos, moisture readings, water category, scope of works, drying logs and final clearance readings. That file is what gets a claim settled without a fight.
Why Floodwater Can't Just Be Dried Out Like a Burst Pipe
This is the part people push back on, and it’s worth explaining properly rather than just telling you the carpet has to go.
The restoration industry classifies water by how contaminated it is. Water from a burst supply pipe is Category 1, clean water, and materials soaked in it can often be dried in place if you get to them quickly. Floodwater is Category 3, the most contaminated class, because it has run across ground surfaces, roads, gardens, drains and sometimes septic systems before it reached your floorboards. Most Australian flood events produce Category 3 water.
That changes what can be saved. Porous materials that have been in Category 3 water cannot be reliably decontaminated, so carpet, underlay, plasterboard, insulation and upholstered furniture come out rather than getting dried. Plasterboard is normally cut back to a set height above the waterline. It isn’t a case of a restorer being cautious or padding an invoice. Porous material behaves like a filter, holding contaminants deep inside where no disinfectant reaches.
There’s a second reason, and it’s the one that matters for what we do. Pathogens and organic material left in those materials don’t disappear when the surface dries. They sit there as food, and the moment there’s moisture again they’re back. That’s the direct line from a flood to a mould problem six weeks later in a house somebody thought was fixed.
So when we tell you the carpet is finished but the floorboards can be saved, or that the bottom of that wall has to come out, there’s a standard behind it. And when something can be saved, we’ll tell you that too, because there’s no sense throwing out a floor that will dry.
If mould has already established by the time we get there, that’s mould remediation alongside the drying. Getting it dry fast is what keeps that from happening.
Why the Illawarra Floods the Way It Does
Our geography is the reason. The escarpment rises to around 700 metres within about 12 kilometres of the coast, and that wall of land forces moist air upward and wrings intense rain out of it. Water then has a short, steep run to the sea through suburbs and undersized drains.
August 1998 is the benchmark. Wollongong recorded 316 millimetres in 24 hours and Mt Ousley 445 millimetres, with the worst of it in a three hour window on the evening of the 17th. More than a thousand homes were damaged and a man tragically lost his life. Rainfall intensity topped 120 millimetres an hour in places, and the escarpment catchments shed close to all of it straight downhill. Blocked drains, choked with debris washed down from above, made much of the damage worse.
It hasn’t stopped since. If you remember, Wollongong has had repeated flash flood events in the years since, with 2022 bringing several across Dapto, Kembla Grange, Bellambi, Thirroul and the city itself. Council has spent decades on floodplain work, detention basins and buying back the worst-affected properties, and the Cabbage Tree Creek catchment through Fairy Meadow, Balgownie, Mount Pleasant and North Wollongong is still one to watch when the rain sets in.
What that means for you: local flooding here arrives fast, carries ground contamination and debris with it, and hits a lot of properties in the same few hours. We know which streets go under, we’re already here when it happens, and we don’t have to be told where Cabbage Tree Creek is.
How Much Does Flood Damage Restoration Cost?
Most flood jobs run through insurance, so the number that matters to you is often your excess rather than the invoice. Our emergency assessment is free.
Flood work costs more than a clean water job, and it’s important to know before you compare quotes. Category 3 water means mandatory removal of porous materials rather than drying them, controlled disposal of that waste, protective equipment for the crew, and antimicrobial treatment through the affected areas. A quote that’s dramatically cheaper than the others usually means someone is planning to dry material that should be coming out.
| Stage | What it covers | Cost |
|---|---|---|
| Emergency assessment | We attend, assess the water category and damage, and document it for your claim | Free |
| Extraction and strip-out | Pumping out, removing contaminated porous materials, disposal | Quoted on site |
| Cleaning and sanitising | Silt removal, antimicrobial treatment of structural surfaces | Priced by area affected |
| Structural drying | Dehumidifiers and air movers, monitored daily until readings confirm dry | Priced by area and days on site |
| Reinstatement | Replacing plasterboard, insulation, flooring and finishing | Quoted with the repair |
What drives the price?
- How deep the water got and how far through the building it went
- How much porous material has to come out
- How long it sat before we started, and
- How many days the drying equipment runs
Getting us there quickly reduces every one of those.
We give you the figures in writing and the documentation your insurer needs before work goes ahead.
Why Being Local Matters When Half the Suburb Floods
Flash flooding doesn’t damage one house, it damages a street. When that happens, restoration crews get booked out fast and the ones based out of Sydney work through their own city first.
We’re in Wollongong. We answer the phone 24/7, and when the escarpment lets go on a Saturday night we’re already here. On a flood job that difference is measured in how much of your house can still be saved.
We also know how these homes are built and where the water ends up in each of them. Raised timber floors that let it straight into the subfloor. Slab-on-ground homes where it wicks up the walls. Apartments where the ground floor and the car park take it first. It also means that we find the moisture faster and dry it in the right order.
Call Us Now, Every Hour Counts After a Flood Event
The water level tells you almost nothing about the damage. What matters is how long the building stays wet, and that clock started when the water arrived.
Call us and we’ll tell you what to do next, get someone out, and document the lot for your insurer. 24/7, no obligation.
Frequently Asked Questions
What should I do first after a flood?
- Stay out of the water and away from anything electrical until it’s been checked.
- Photograph everything before you move it, including the high-water mark and where the water came from.
- Then call us before you start pulling up carpet, because what gets saved and what gets thrown out affects your claim.
- Stay out of the water and away from anything electrical until it’s been checked.
Is floodwater dangerous?
Treat it as contaminated.
It has run across ground, roads, gardens and drains before reaching your home, so it can carry bacteria, chemicals and sewage.
Wear gloves and boots, wash thoroughly after any contact, keep children and pets out of it, and don’t attempt a clean-up of a large affected area yourself.
Why does the carpet have to be thrown out when it looks fine?
Because floodwater is classed as grossly contaminated, and porous materials like carpet and underlay hold the contamination deep inside where cleaning can’t reach.
Industry standards require them to be removed rather than dried. It’s the same reason plasterboard and insulation come out to a set height above the waterline.
How quickly does mould grow after flooding?
It can take hold within a day or two of materials staying wet, and warm humid conditions speed it up.
Getting a professional assessment as soon as it’s safe to enter, ideally within the first couple of days, is what keeps a flood from turning into a mould job.
I don't have flood cover. Am I covered at all?
Possibly, and it’s worth checking rather than assuming. Flood has a legal definition in Australia and refers to water escaping from a watercourse, dam or similar. Flash flooding from intense rain, which is the common pattern in the Illawarra, is often classified as stormwater or rainfall runoff and is covered by most policies. Some insurers do exclude runoff where flood cover was declined, so read your policy and speak to your insurer.
Will you work with my insurance company?
Yes.
We document the job the way insurers expect: photos, moisture readings, the water category, scope of works, drying logs and final readings showing the structure is dry. That’s what settles a claim without a drawn-out argument.
How long does drying take after a flood?
Usually longer than a clean water job, often a week or more, because there’s typically strip-out work before drying starts and the materials involved have been thoroughly saturated.
We keep the equipment running and monitored until the readings confirm dry, rather than to a set number of days.
My house flooded weeks ago and now it smells musty. Is it too late?
Not too late, but it does mean mould has almost certainly established in materials that stayed wet.
That becomes a remediation job as well as a drying one. Call us and we’ll find where the moisture still is and what’s growing on it.
