Blocked Drains / Double Bay

Blocked Drains Double Bay

Same-day drain clearing across Double Bay — camera inspection, high-pressure jetting, and a fixed price before we start.

$0 call-out fee — any hour, any day · Available 24/7

Double Bay sits at the bottom of a stormwater catchment of about 2.8 square kilometres, taking in parts of Edgecliff, Woollahra and Bellevue Hill, on low ground that was swamp and market gardens behind the beach. So its blocked drains are as much about stormwater as sewer. Add the restaurants and cafés around Knox, Cross and Bay Streets, basements that drain to a pump-out pit, and the fact that about three in four homes are flats or apartments.

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

Runoff from Bellevue Hill, Woollahra and Edgecliff all heads for the Double Bay flat, and Coopers Creek runs in covered channels under the shops to the bay. When the public system is running full, a private stormwater line that is already partly blocked with silt or leaves is the first thing to overflow. Jetting the line and clearing the pits means it can empty as soon as the street system recovers.

Commercial kitchens send fats and food scraps into their drains every service. A grease arrestor that misses its service or a waste line that is never jetted is the usual reason a kitchen drain stops halfway through dinner. A plunger will not shift set grease; the high-pressure jet blaster scours it off the full width of the pipe.

With most homes in apartment buildings, one blocked stack can back up into the lowest units first. Below street level, basements often drain to a pump-out pit, and a pit half full of silt or a pump that has quietly failed is usually found out in the next heavy storm.

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 low parts of Double Bay it is often because the public drainage downstream is full, so your stormwater has nowhere to go. We check that your own pits, grates and pipes are clear and graded towards their outlet, so they can empty as soon as the street system can take the water.

Yes. We schedule commercial jetting early or late so it does not interrupt trade, and in an emergency we answer the phone 24/7.

Often it is a blockage in the shared stack below you rather than in your unit. We find where it is with a CCTV camera, so the owner or the owners corporation knows whose it is to fix.

Yes. We clear silt and debris from the pit, check the pump and its discharge line, and tell you if the pump is near the end of its working life so it can be replaced before the wet season rather than during it.

Our phones are answered 24/7, and for emergencies we aim to be there within 60 minutes, 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.
