Blocked drains in the Hills are often not about what went down the drain at all. Reactive clay soil swells when wet and shrinks when dry, and over years it pulls joints apart and cracks pipe on the long runs that large blocks require. The blockage is a symptom; the soil is the cause.

The same job on camera: roots through a joint at 12.59 m. We locate the fault before we quote the fix.

Reactive clay moves whatever is buried in it. Joints separate and pipe cracks, and debris catches at the fault. Clearing it will not keep it clear.

Bigger homes on bigger blocks mean more pipe between house and connection — more joints, more fall to maintain, more places for a fault to sit unnoticed.

Clay does not absorb well, so stormwater has to be moved rather than drained into the ground. An undersized or partly blocked system leaves water ponding on the surface.

Fixed price quoted before we start. $0 call-out fee.

How It Works

01

Plunger or drain auger for a blockage near the fixture, the jet blaster for the main line.

02

For repeat blockages, a CCTV camera shows what is in the pipe and exactly where.

03

If the pipe is damaged, we explain relining or replacement, with a fixed price first.

04

We make sure the drain is flowing freely before we leave.

Common Questions

In the Hills that usually points to soil movement cracking the pipe rather than anything you have done. A camera inspection confirms it.

Often yes, where the pipe is still structurally continuous. Where a section has dropped or separated completely it needs excavating — the footage shows which, and we will show you.
