Burst Pipe Water Damage in Wollongong
Pipe let go and there’s water through the house? We’re Wollongong based and we answer the phone 24/7.
What To Do Right Now, Before We Get There
If water is still running, work through this first. It takes two minutes and it makes a real difference to what the job ends up costing you.
Turn the water off at the mains
Your water meter is usually near the front boundary. Turn the tap clockwise until it stops. If the leak is under a sink or behind a toilet, there may be a small isolation valve right there you can close instead.
Turn off the power to affected areas if you can do it safely
Water and electricity in the same room is the part of this that can actually hurt you. If the switchboard is wet, or water is anywhere near powerpoints or light fittings, don’t touch it. Call an electrician or leave it to us.
Get what you can up off the floor
Rugs, boxes, anything with a fabric base, and lift furniture legs onto blocks or foil if it’s sitting in water.
Photograph everything before you clean up
Wide shots of each room, close shots of the damage, and a photo of the hose or pipe that failed. Do this before anything gets moved or mopped. If you end up claiming, these photos matter more than anything you say later.
Don’t wait for it to dry on its own
Water travels sideways under floors and up inside walls, and mould can take hold within a day or two. The damage that costs you is nearly always the water you can’t see.
FREE INSPECTION, NO OBLIGATION
We will call you back personally to arrange a time.
Trusted Burst Pipe Water Damage Restoration across the Illawarra
A burst pipe is different to a storm or a flood. There’s no warning, no weather to watch, and it happens inside the house, often overnight or while you’re away. People come home to a ceiling on the floor and the downstairs carpet under an inch of water.
Where it does the most damage is out of sight. Water at mains pressure finds the gaps, runs along joists, soaks into wall cavities, gets under floating floors and sits in insulation. You mop the visible water, the surface looks dry in a day, and the moisture behind the plasterboard stays there feeding mould for weeks.
We’ve been doing water damage and mould work across the Illawarra for 15 years here at Wollongong Mould Cleaning & Removal. We’re locally based, so we can be there quickly, and we run a 24/7 callout because a burst pipe at 11pm doesn’t wait until Monday.
Is this you?
- A pipe, flexi hose or fitting has let go and water has spread through the house
- Water came through the ceiling from a bathroom or pipe upstairs
- You came home or woke up to it and don't know how long it ran
- Carpet, floorboards or a floating floor have been soaked
- The surface looks dry but there's a damp smell, or the skirting is swelling
- The plumber has stopped the water and now you need the drying done
- You need to lodge an insurance claim and want it documented properly
Call us and we’ll talk you through it on the phone, then get someone out.
Burst Pipe or Storm Damage? The Difference Matters for Your Claim
Both leave you with a wet house, but insurers treat them very differently, so it’s worth knowing which one you’ve had.
A burst pipe is sudden internal water. A pipe, a fitting or a flexi hose fails and releases clean mains water inside the building. It’s usually the strongest position to be in with an insurer, because it’s a sudden and identifiable event rather than something that crept up.
Weather events are the other category. Water entering from outside during a storm, or rising floodwater, are assessed under different parts of your policy, sometimes with separate excesses or optional flood cover. Those sit with storm damage restoration and flood damage restoration.
The third category is the one that catches people out: a slow leak that’s been going for months. That’s typically treated as gradual damage and is often excluded. It’s also why the wording you use with your insurer matters, and why photographing the failed part on day one is worth doing.
If mould has already taken hold from water that sat too long, that becomes a mould remediation job as well as a drying one.
How We Dry Out a Burst Pipe Job
We make the site safe and stop the spread
First job is containing where the water can still travel, protecting what can be saved, and making sure nothing electrical is live near water.
We extract the standing water
Proper extraction units, not a mop and a wet vac. The faster the bulk water is out, the less of it soaks into materials that are expensive to replace.
We map the moisture, including what you can’t see
This is the part that separates a dried house from a house that looks dry. We use moisture meters and thermal imaging to find where the water has actually travelled: inside wall cavities, under floating floors, into insulation and along the underside of the floor. Water spreads much further than the wet patch suggests.
We set up structural drying and monitor it
Air movers and commercial dehumidifiers, positioned for the way your building is built, then monitored with readings over several days rather than guessed at. Cavities often need targeted drying, injecting dry air directly into the wall or floor space. There’s more on how that works on our dehumidification and structural drying page.
We deal with carpet, flooring and soft furnishings
Some carpet can be saved with extraction and sanitising, some can’t, and underlay usually can’t. We’ll tell you which is which rather than charging you to dry something that’s finished, and the detail sits on our water-damaged carpet and sanitisation page.
We document the lot for your insurer
Moisture readings, photos, what was affected, what was done, drying logs and the final readings that show the structure is actually dry. That’s what an insurer wants to see, and it’s what settles a claim without an argument.
The Flexi Hose Behind Your Toilet Is the Most Likely Thing to Flood Your House
Most people picture a burst pipe as a copper line inside a wall. In Australian homes the far more common culprit is a flexi hose: the short braided steel hose connecting the water supply to your toilet cistern, taps, dishwasher or washing machine. They cost under twenty dollars and there are usually a dozen or more in a house.
The numbers are worth reading twice. Analysing more than 22,000 home water damage claims, Suncorp found that about one in ten were caused by a burst flexi hose. Their 2026 figures put the average claim at $30,000, up from $27,500 the year before, and six per cent of those claims now top $100,000.
Then there’s how many are sitting there ready to go. Suncorp spent six months inspecting customers’ hoses and found 30 per cent were at risk of bursting and needed replacing, an average of two in every home. They are designed to last five to ten years. One of their assessors, a licensed plumber, put the scale of a failure plainly: a burst hose left undiscovered for 24 hours can release enough water to fill a household swimming pool.
Despite all that, around 60 per cent of homeowners have never had their hoses inspected at all.
One Suncorp claim shows what the worst case looks like. A bathroom hose let go while the owners were overseas and ran undetected for roughly two days. Water went through the master bedroom, ensuite, four more bedrooms, the kitchen, lounge and study. The family was out of the house for months while it was gutted and rebuilt, and the final bill passed $500,000.
Why flexi hoses fail, and why installation matters so much
Suncorp’s head of claims and assessing describes the cause as almost always the same thing: corrosion, rust, or a hose that was twisted or kinked when it was installed.
That last one is worth sitting with, because it is the part you can control. A hose that is slightly too long gets bent to fit the space. A nut gets done up while the hose is held at an angle, leaving a twist in it. Neither looks like a problem on the day. Both create a permanent stress point that fails quietly years later.
It is also why do-it-yourself installs are over-represented in these failures. Behind a toilet cistern or inside a cramped vanity is exactly the sort of spot where it is hard to see what you are doing and easy to leave a kink in the hose without realising.
Access is the other half of the story, and it is why so many old hoses stay in place. The hoses inside toilet cisterns and behind heavy appliances are the hardest ones to inspect. Getting a plumber out to a hose you cannot easily reach costs money today, the hose looks perfectly fine, so it goes on the list of jobs to do when there are a few things worth a call-out for. With money tight, that list keeps getting bumped. Meanwhile the hose is nine years old.
The insurance catch nobody mentions
Here is the part worth knowing before you need it, rather than after.
Escape of liquid cover pays for the damage the water caused. As CHOICE explains, it does not cover repairing or replacing the item that leaked in the first place, and damage from leaks caused by poor maintenance is generally excluded.
That exclusion is where flexi hoses get awkward. A hose that failed suddenly is one thing. A hose that was visibly rusted, frayed or kinked for a year before it went can be assessed as gradual damage rather than a sudden event, which is a very different conversation with an assessor. Some insurers also look harder at a claim where there has already been a flexi hose failure at the same address, on the reasoning that the rest of them were due for attention.
Warranties do not help as much as people assume, either. Quality hoses carry ten and fifteen year warranties, which sounds reassuring and quietly cuts against the five year replacement advice, so the hose stays where it is. And a warranty on a twenty dollar part is a very different thing from a claim for the damage that part caused.
What to actually do about it
This costs almost nothing and takes ten minutes twice a year.
Put your head under the sink, behind the toilet and behind the washing machine, and look at each hose for rust spots, fraying in the braid, kinks, twists or discolouration. Any of those and it needs replacing now, not later. Replace them at around the five year mark whether they look worn or not. And write the install date on the hose or inside the cupboard door with a marker, because otherwise nobody has any idea how old they are. They all look identical whether they went in last month or twelve years ago.
Do that and there is a decent chance you never need to call us for this at all. We would rather tell you that than not.
Where Burst Pipe Water Ends Up
Water from a burst pipe rarely stays in the room it started in. Here’s where it goes and what each part needs.
- Soaked carpet and underlay, which need extraction and sanitising, and sometimes replacement of the underlay even where the carpet is saved. That’s water-damaged carpet and sanitisation.
- Wall cavities and under floating floors, where the water sits out of sight and takes specialist equipment to dry properly. That’s dehumidification and structural drying.
- Down through the ceiling from a bathroom or pipe on the floor above, which often means saturated plasterboard and insulation that has to come out.
- Into the subfloor, where it soaks the joists and bearers and can sit for months. If yours is a raised timber floor, see subfloor mould removal.
- Left long enough, into mould through the affected rooms, which needs mould remediation rather than drying alone.
- Soaked carpet and underlay, which need extraction and sanitising, and sometimes replacement of the underlay even where the carpet is saved. That’s water-damaged carpet and sanitisation.
Once everything is dry, putting the house back together, plasterboard, insulation, flooring and paint, is part of the job and carries into our building restoration work.
How Much Does Burst Pipe Water Damage Restoration Cost?
Most burst pipe jobs go through insurance, so for a lot of people the real number is their excess rather than the invoice. For scale, Suncorp puts the average burst flexi hose claim at $30,000, with six per cent of them passing $100,000. That is what clean water at mains pressure can do to a house in a few hours.
The emergency assessment is free. What the job itself costs depends almost entirely on how long the water ran and how far it travelled.
| Stage | What it covers | Cost |
|---|---|---|
| Emergency assessment | We attend, find where the water has gone and tell you what it needs | Free |
| Extraction and make safe | Removing standing water and protecting what can still be saved | Quoted on site |
| Structural drying | Air movers and dehumidifiers, monitored daily until readings confirm dry | Priced by area and days on site |
| Reinstatement | Replacing plasterboard, insulation, flooring and finishing | Quoted with the repair |
Drying is priced on the size of the affected area and how many days the equipment has to run, because a floor that’s been wet for six hours dries far faster than one that sat for three days. That’s the honest reason we push you to call straight away rather than waiting to see how it dries out.
We give you the figures in writing, and the documentation your insurer needs, before the work goes ahead.
Why a Local Team Matters When Water Is Still Running
With a burst pipe, response time is the job. Every extra hour is more water into the plasterboard, further along the joists and deeper into the flooring, and the difference between drying a room and rebuilding it.
We’re based in Wollongong, so we’re not driving down from Sydney while your ceiling gets heavier. We answer the phone 24/7, because these things happen at 2am and on long weekends, which is precisely when a hose that’s been left in for a decade tends to give up.
We also know the local housing. Raised timber floors that let water run straight into the subfloor, two-storey homes where an upstairs ensuite empties into the living room ceiling, and units where your burst pipe becomes the neighbour’s problem too. Knowing where the water goes in each of them means we find it faster.
Call Us Now, the Sooner We Start Drying the Less You Lose
If water is still running, turn it off at the mains and call.
If it’s already stopped, call anyway, because the moisture in the walls and under the floor is doing damage right now whether you can see it or not.
We’ll talk you through what to do, get someone out, and document it properly for your insurer. 24/7, no obligation.
Frequently Asked Questions
What should I do first when a pipe bursts?
- Turn the water off at the mains, which is usually a tap near your front boundary at the meter.
- Then turn off power to any affected area if you can do it safely, and stay away from wet powerpoints and light fittings.
- Photograph everything before you start cleaning up, then call us and a plumber.
How quickly does mould grow after a burst pipe?
It can start within a day or two of materials getting wet, which is why drying quickly matters so much.
Mould that’s already taken hold needs remediation, not just drying, and that’s a bigger job than getting the water out on day one.
The floor looks dry. Do I still need it professionally dried?
Very likely, yes.
Surfaces dry long before the material underneath does. Water sits in wall cavities, in insulation, under floating floors and in the subfloor, and it can look completely normal from the room while still being wet enough to grow mould.
Moisture meters and thermal imaging are the only way to know.
Is a burst pipe damage covered by insurance?
Usually, because it’s a sudden event rather than gradual damage, and that’s the category insurers cover most readily.
It depends on your policy though, and a hose or pipe that was visibly deteriorating before it failed can be assessed differently.
Talk to your insurer early, and keep the failed part and your photos.
Why do flexi hoses burst so often?
They corrode on the outside, break down on the inside under constant pressure, and fail at any point where they’ve been kinked or twisted during installation.
They’re only designed to last five to ten years, and most people have never checked or replaced theirs.
Suncorp found 30 per cent of the hoses they inspected were already at risk.
How often should flexi hoses be replaced?
Every five years is the general advice, and check them twice a year for rust, fraying, kinks or discolouration.
Write the install date somewhere near them, because they all look the same whether they’re brand new or twelve years old.
Do you work with insurance companies?
Yes.
We document the job the way insurers want it: photos, moisture readings, drying logs, scope of works and final readings confirming the structure is dry. That’s what gets a claim settled without an argument.
How long does drying take?
Most jobs run three to five days of equipment on site, monitored daily.
It depends on how long the water ran, how far it travelled and what materials got wet. We keep drying until the readings say it’s dry, not until the calendar says so.
