Water Ingress Investigation and Flood Testing Melbourne

Water coming through walls, windows, ceilings or balconies? Plumb Melbourne investigates the source across south-east Melbourne so the right repair is made first.

Water ingress is rarely obvious. A stain on a ceiling or a damp patch on a wall can come from a leaking pipe, a failed drain, a roof or gutter fault, or water getting in through windows, walls, or a balcony. Repairing the wrong thing costs money and the problem returns.

Our licensed plumbers use pressure testing, moisture readings, and flood testing to isolate each possible source, one at a time, and rule it in or out. Where plumbing is the cause, we repair it. Where it isn't, we tell you, and give you photos and a written report to take to your builder, waterproofer, window specialist, or insurer.

This suits houses, apartments, and commercial properties, and is especially useful for strata and rental properties where several parties need to agree on the cause. We service Glen Iris, Camberwell, Malvern, Toorak, Caulfield, Carnegie, Bentleigh, Brighton and surrounding inner east and south-east Melbourne suburbs.

When you need to call a plumber

Ceiling stains with no obvious source

We test each possible source in turn, from pipes and drains to roof plumbing and balconies.

Damp patches on walls or around windows

We use moisture readings to trace where water is entering.

Leaks after rain that nobody can find

We inspect roof plumbing, gutters, and external drainage to identify rain-related entry points.

Suspected shower or balcony leak

We flood test the area to confirm whether it is leaking before any work starts.

Disagreement about the cause between owner, tenant, builder, or strata

We provide a written report with photos and test results so everyone is working from the same facts.

What is flood testing and when is it used?

Flood testing involves temporarily blocking a drain or outlet and holding water to a set level in an area, such as a balcony, shower base, or bathroom floor, then monitoring whether the water level drops or damp appears below. It helps confirm whether a suspected area is leaking before any repairs or demolition. It is one of several methods used to isolate a leak, alongside pressure testing and moisture readings. A plumber will usually combine them to rule out sources one at a time and give you a documented result.
