The same burst pipe costs three very different amounts depending on whether you can reach it. Here are the 2026 ranges by access type, what leak detection adds, and what to do in the first five minutes.
These are typical price ranges for the Illawarra and NSW, drawn from published 2026 industry pricing data — not a quote, and not our fixed prices. What your job actually costs depends on access, the age and condition of the plumbing, parts, and whether it is after hours. We give you a fixed price before we start work, so you are never guessing.
Burst pipe pricing is almost entirely about access. The pipe itself, the fittings and the labour to make the joint are a small part of the invoice. What you are really paying for is getting to it and putting back what had to come out.
The ranges below are published 2026 NSW figures. The access breakdown comes from a single source, so treat the tiers as indicative rather than settled — but the shape of it matches what the work actually involves.
Before after-hours loading. Emergency attendance outside standard hours adds 30 to 50 per cent on weeknights and 50 to 100 per cent on weekends.
| Job | Typical range | What affects it |
|---|---|---|
| Exposed or accessible pipe | $250 – $500 | Under a sink, in a cupboard, on an external wall. |
| In-wall pipe | $400 – $800 | Includes opening and making good the wall. |
| Underground, with excavation | $800 – $2,500+ | Driveways, paving and deep runs push this higher. |
| Leak detection (before any repair) | $250 – $600 | Acoustic and thermal. Finds it without digging up the yard first. |
An underground repair means excavation, and excavation means whatever is on top of the pipe. A run under lawn is a morning's work. The same run under a concrete driveway, a paved courtyard or established landscaping is a different project, and reinstating the surface is often the largest line on the invoice.
This is exactly why leak detection earns its cost. Acoustic and thermal equipment locates the failure to within a small area, so you excavate once in the right place rather than opening a trench along the whole run hoping to find it.
Turn off every tap and appliance in the house, including the washing machine, the dishwasher and any irrigation. Go out to the water meter and watch the smallest dial for a few minutes. If it is still turning, water is going somewhere it should not.
Other signs worth acting on: an unexplained jump in the bill, a warm patch on the floor, a musty smell in a room, paint bubbling on a wall, or a patch of lawn that stays green through dry weather. A slow leak that runs for months does far more damage than the repair would have cost, and many insurance policies treat gradual damage differently from a sudden burst.
Age. The Illawarra has a lot of ageing pipework — post-war stock in the older Wollongong suburbs, and the 1980s Gainsborough Estate homes in Kiama Downs now at around forty years, which is when original runs start letting go.
Salt. Coastal properties corrode faster. Homes near the surf at Gerroa, Minnamurra and Werri Beach see failures earlier than equivalent houses inland.
Ground movement. The escarpment side of the Illawarra gets significant movement after heavy rain, and buried pipework is not flexible. Underground failures often follow a big weather event by weeks rather than appearing during it.
Water hammer. That bang when a tap or a washing machine valve shuts. It is a pressure spike hitting the pipework repeatedly, and over years it works joints loose. It is cheap to fix and worth doing.
We handle burst and leaking pipes across the Illawarra, with 24/7 emergency callout and non-invasive leak detection so we are not digging up your yard to find the problem. More on pipe repairs, leak detection, or emergency plumbing.
Published 2026 ranges are roughly $250 to $500 for an exposed or accessible pipe, $400 to $800 for a pipe inside a wall including making good, and $800 to $2,500 or more where excavation is needed. Leak detection, if the leak has to be located first, runs $250 to $600. After-hours attendance adds to all of these.
Turn the water off at the meter — usually at the front boundary — and turn it clockwise until it stops. If water is anywhere near electrical outlets, switchboards or lighting, turn the power off at the switchboard as well and do not touch anything wet. Then open the lowest tap in the house to drain the remaining pressure, and photograph the damage before you clean up, for insurance. Then call.
Because finding a concealed leak and fixing it are two different jobs. Acoustic and thermal equipment locates a leak under a slab, in a wall or underground without excavating the whole run first, which is almost always cheaper than digging speculatively. On an obvious burst you can see, no detection is needed and you should not be charged for it.
Most home policies cover the resulting water damage but not the failed pipe itself, and many exclude damage from gradual leaks as opposed to sudden bursts. That distinction is why it is worth acting fast on a suspected slow leak, and why you should photograph everything before cleaning up. We are not insurance advisers, so check your policy wording, but we can provide a written report on the cause if your insurer asks for one.
Turn off every tap and appliance in the house and watch the water meter. If the dial is still moving, water is going somewhere. Other signs are an unexplained jump in the bill, a warm patch on a floor, a musty smell, paint bubbling on a wall, or a patch of lawn that stays green through dry weather. Any of those is worth a leak detection visit before it becomes a repair to the structure as well as the pipe.
Ageing pipework is the main driver, and the Illawarra has plenty of it — from post-war stock in the older Wollongong suburbs to the 1980s Gainsborough Estate homes in Kiama Downs now at forty years. Coastal properties add another factor: salt accelerates corrosion on copper and on fittings, so homes near the surf at Gerroa, Minnamurra and Werri Beach tend to see failures earlier than equivalent houses inland.
