Which suburbs around Wanneroo do you cover?

Wanneroo plus Hocking, Pearsall, Sinagra, Wangara, Gnangara, Jandabup, Mariginiup, Pinjar and nearby streets. If you’re not sure which side of the boundary you’re on, call (08) 6187 3999 with the street name.

How quickly can you get to Wanneroo from Ellenbrook?

It depends where we are when you ring. Wanneroo is a cross-town run from Ellenbrook, so we give a real ETA on the phone rather than a promise we can’t keep. Planned jobs get a booked window.

Do you work on commercial units in Wangara?

Yes, for licensed plumbing and gas work on warehouses, workshops and small commercial tenancies — leaks, blocked amenities, hot water and gas connections. Tell us about access hours and any site rules when you book.

Can you fix a bore or reticulation on a Wanneroo lifestyle block?

We work on the potable plumbing and licensed gas. Bore pumps, controllers and garden irrigation are usually a reticulation specialist. If the leak or fault is on the house water side of the setup, that’s us — call and describe it.

Do you do gas fitting in Wanneroo?

Yes. McDermott Plumbing does licensed gas fitting, including cooktop and hot water connections and gas leak checks. If you smell gas inside, get out, avoid switches and phones near the smell, and call ATCO on 13 13 52 first.

How we cover Wanneroo

Wanneroo is north-west of Ellenbrook across the Gnangara pine belt and Wanneroo Road. It isn’t next door, but it’s a regular run for us rather than a once-a-month favour. For planned work — hot water replacements, rental make-safes, shop fit-offs in Wangara — we book a set time. For emergencies, ring and we’ll say how long from where we are. If a closer crew can get to you sooner, we’ll say that too.

What we see around Wanneroo

The City of Wanneroo mixes town-centre housing, 2000s estates, market-garden fringes and industrial yards. That mix shows up in the plumbing:

Hocking, Pearsall and Sinagra: mostly 2000s brick-and-tile homes. Many are due for their first or second hot water replacement, often a gas storage unit on an outside wall, plus ageing flexi hoses under sinks and toilets.
Wanneroo township and older streets: a wider mix of eras, including copper supply lines and clay or older PVC sewer laterals that block when street trees push roots in.
Wangara: warehouses, trade workshops and small commercial units. Jobs here are often after-hours leaks, blocked amenities, or gas and hot water on a commercial tenancy — tell us about access and any site induction when you book.
Gnangara, Jandabup, Mariginiup and Pinjar: larger semi-rural lots with long supply runs from the meter, garden and bore pipework, and sheds that share the house water. We fix licensed plumbing and gas on the house and outbuildings; bore pumps and irrigation controllers are a different trade unless the fault is on the potable side.
Sandy soils across much of the corridor shift poly and copper lines between the meter and the house, which is a common source of unexplained high water bills.

Blocked sewer? Who pays

If a toilet won’t flush or the overflow relief gully is full, the blockage is usually in the property sewer up to the Water Corporation connection. That’s the owner’s job. If we find the problem is in their main, we report it and their crew clears it. Sewage overflowing on the property: call Water Corporation on 13 13 75 as well as us.
