Signs You Need a Plumber in Kwinana
Kwinana's housing comes in two very different waves: original homes from the 1950s and 60s, and new estates built in the last couple of decades. The problems we see depend on which one you're in. If any of these sound familiar, get it looked at before it turns into a bigger job.
Drains gurgling, backing up or slow to clear. Older homes on big blocks often have long drain runs and mature trees. Roots find their way into old joints, and gurgling usually comes before a full blockage.
A water bill that jumped for no obvious reason. Other signs are a damp patch, a warm spot in the floor, or a meter moving with every tap off. If your home was built between 2005 and 2015, get pipe leaks checked early.
Planning a bathroom, kitchen or laundry update in an older home? Original fittings in homes of this age were never designed for today's appliances and water pressure. Some original homes also have asbestos sheeting in the walls. We'll flag that before any work starts so the job is planned properly.

What our customers are saying…
Kwinana: What We See Locally
Kwinana was a planned town. The State Government built it in the early 1950s to house workers for the new oil refinery, starting with Medina, and Orelia, Calista and Parmelia followed. Several suburbs are named after the ships that brought the first settlers to the Swan River Colony.
Many of those original homes were weatherboard to window height with asbestos sheeting above, on large blocks, often 730 square metres or more. That shapes the plumbing work in the older streets:
-
Drain runs tend to be long, and mature trees mean root intrusion is common.
-
Pipework and fittings are often decades past their design life.
-
Renovations need planning around any asbestos sheeting before walls are opened.
Newer suburbs like Wellard and Bertram are a different story. The issues there are more about installations, fit-outs and new-build defects.
If your home was built between 2005 and 2015, Iplex pipe failures and BGC Construction plumbing defects affect homes from that era across the southern corridor. A persistent leak or unexplained water bill is worth checking early.
