Emergency blocked drains in St George
Updated October 2026
Some drain problems can wait until Monday. Sewage coming up through the shower drain is not one of them. If waste water is backing up inside your home, a toilet is overflowing, or stormwater is rising towards the house, you need a licensed drain plumber now, not a booking next week.
St George Blocked Drains connects you with licensed local drain plumbers who take emergency and after-hours work across St George, from Hurstville and Kogarah to Rockdale, Bexley and the Georges River suburbs. Send the quote form with a note that it is urgent and your details go straight through.
What counts as a drain emergency
- Sewage backing up into the house through floor drains, showers or toilets
- Every drain in the house blocked at once, which points to the main sewer line
- A toilet overflowing that will not stop with the water off
- Stormwater pooling against the house or garage during rain
- Strong sewage smell inside with gurgling from multiple drains
One slow sink is a booking. Waste water where you live is an emergency.
What to do right now
While you wait for a call back, three things limit the damage. Stop putting water down the drains, so no washing machine, dishwasher or showers. If sewage is surfacing at an outside gully, that gully is doing its job by keeping the overflow outside, so do not cap it. Keep people and pets away from any surfaced waste water, and if it has touched carpets or floors inside, photograph everything before cleaning for your insurer.
In a unit block, tell the strata manager or building manager as well. A blocked shared line affects every unit connected to it, and the fix is usually arranged through the owners corporation.
What emergency drain work costs
After-hours call-outs cost more than booked weekday work, and that is true of every plumber in Sydney. A standard clear that costs $150 to $400 in business hours will sit higher at night or on a Sunday. The licensed plumbers we work with still quote before they start, so you know the price up front. If the problem can safely wait until morning, they will tell you that too, because a booked morning job is cheaper than a midnight one.
Why mains matter in an emergency
If every fixture in the house is backing up, the blockage is usually in the main sewer line between the house and the Sydney Water connection point. If your neighbours have the same problem at the same time, the fault may be in Sydney Water's main itself, and Sydney Water fixes its side at no cost to you. A licensed drain plumber can usually establish which side of the connection the problem sits on, which can save you the whole bill.
Frequently asked questions
Can I get a plumber in the middle of the night?
Often, yes. Many of the plumbers we work with take after-hours calls. Expect a higher call-out rate, quoted before work starts.
Is sewage backup dangerous?
Treat it as contaminated. Keep children and pets away, wear gloves if you must touch anything, and wash thoroughly afterwards. Professional cleaning is worth it for any indoor spill.
Will my insurer cover an overflow?
Many home policies cover sudden water damage inside the house, though usually not the drain repair itself. Photograph the damage before cleanup and check your policy.
I live in a unit. Who do I call?
If the blockage affects only your unit's fixtures, it is usually yours to fix. If several units are affected, it is likely a common property line, so let your strata manager know as well as requesting a quote.
