Concord is our home suburb. Mr. Clog is based here, so Concord blocked drains are close to home for us. Most of the suburb was built between the wars, and the typical house is a brick bungalow still draining through the earthenware sewer it was built with, under a back garden that has had a century to grow. Between the reserves, the Parramatta River bays and the established gardens, there is no shortage of trees looking for water, and on the low ground towards Exile Bay stormwater is the other problem.

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

The bungalows built across Concord in the 1920s and 1930s drain through earthenware pipe with a joint every short length. Roots find those joints, and once they are in they grow back after every clearing. A drain that blocks on a cycle usually has roots in it, and a CCTV camera shows where they are getting in and whether the pipe is sound enough to reline.

Many Concord homes have been extended or had a bathroom added at the back, joined onto drainage laid when the house was built. When a newer bathroom drains slowly or gurgles, the fault is often where new pipe meets old rather than in the fixture, and the camera shows the join.

Streets that fall towards Exile Bay and the river carry stormwater from the higher ground behind them. A pit full of silt and leaves, or a line under a driveway that has cracked or been crushed, shows up as water pooling against the house in heavy rain. The high-pressure jet blaster clears the line; the camera shows whether it needs repair.

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

Yes. Mr. Clog is based in Concord, so Concord, Cabarita, Mortlake and North Strathfield are the streets closest to home.

Most often it is tree roots in the joints of the original clay sewer. Clearing them with the jet blaster gets it flowing again, but they grow back through the same joints. A camera inspection shows whether relining will stop it or a section needs to be dug up and replaced.

Usually. Where the camera shows the old pipe is sound enough, relining repairs it from the inside through existing access points, so the garden and driveway stay where they are. Where a section has collapsed, it has to be dug up and replaced, and we show you the footage first.

That points to stormwater rather than sewer; they are separate systems. On the low ground towards the bays a partly blocked pit or line is the usual cause, and jetting it clears the silt and debris.

We are based in Concord. For emergencies we aim to be there within 60 minutes, any hour, with a $0 call-out fee.

It depends on where the blockage is and what is causing it. You get a fixed price before we start, and there is a $0 call-out fee.
