"How much will it cost?" is the first question most people ask, and the honest answer is that it depends on the job. A dripping tap and a collapsed sewer pipe are both "plumbing", but they have very little in common on price. Rather than throw around numbers that won't match your situation, here's what actually moves the price on the most common jobs we see around Mandurah and the Peel region.
Blocked drains
The big variables are where the blockage is and what's causing it. A blocked basin trap is quick. A main sewer line blocked by tree roots, which is common under older homes in Halls Head and Dudley Park, may need high-pressure jetting and a camera inspection to see whether the pipe is damaged. If it is, a repair is a separate job. See our blocked drains page for how we approach it.
Leaks and burst pipes
A leak you can see under a sink is straightforward. A leak you can't see is mostly a finding job. In sandy coastal soil, water often drains away without leaving a wet patch, so locating an underground leak takes time and the right equipment. After that, price depends on access: through a wall, under pavers, or under a slab.
Hot water systems
A repair, such as a thermostat, element or valve, is usually a smaller job than a replacement. For a new system, the price depends on:
- The type: electric storage, gas storage, continuous flow, heat pump or solar
- Whether you're replacing like-for-like or changing type, which can mean new gas, power or pipework
- Where it's going and how easy the old unit is to get out

Gas fitting
Gas jobs include installing cooktops, heaters and bayonet points, running new gas lines, and connecting or converting LPG bottle setups on outer properties that aren't on mains gas. The length of pipe run, the appliance and any compliance testing all affect price. Gas work is licensed work and must be done by a licensed gas fitter.
Septic and ATU properties
On semi-rural blocks around Karnup, Pinjarra, Nambeelup and the Yunderups, a slow drain can be a pipe problem or a system problem. Working out which comes first, and the answer changes what the job involves.
