Mr. Clog Plumbing

24 Hour & After Hours Plumber Sydney

Nights, weekends and public holidays: what needs a plumber tonight, what can wait until morning, and how an after-hours call works.

No surprise bills: $0 call-out and a fixed price before any work starts.

Our guarantee: 12 months on our workmanship, in writing. What it covers

Pipes rarely choose office hours to fail. A flexi hose lets go at 11pm, the only toilet overflows on a Sunday, the hot water tank splits on a public holiday with the whole family home. Mr. Clog takes calls around the clock, weekends and public holidays included, and sends a licensed plumber out after hours for problems that can't safely wait. Not every fault needs a night-time visit, though. The guide below helps you sort the urgent from the inconvenient, explains how an after-hours call and its pricing work, and lists a few checks worth doing before a long weekend or a holiday away.

  • Phones answered 24/7, including weekends and public holidays
  • $0 call-out fee at any hour, day or night
  • A fixed price before any work starts
  • Fully stocked vans, so most jobs are fixed on the first visit
  • Licensed & insured plumbers

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

The phones don't switch off at 5pm on a Friday.

Calls are answered through the night, every night. If the problem can't wait, a licensed plumber comes out. If it can, we'll say so and book a daytime visit.

Saturday and Sunday are normal working days for our phones. A blocked only toilet on a Saturday morning doesn't have to wait until Monday.

Christmas, New Year, Easter and long weekends included. We answer every day of the year.

These get worse by the minute or put people at risk, so don't wait for Monday. Our emergency plumbing page covers what to turn off for each one while you wait.

A burst pipe, a split flexi hose or a leak that keeps running after you close the nearest valve.

Water coming through a ceiling light, pooling near power points or reaching the switchboard. Keep clear of it and treat the electrical risk first.

A floor waste, shower or toilet backing up with waste water. Stop using water in the house until it is cleared.

With a second toilet it can wait. With only one, it can't.

Water running from the tank itself, not just a drip from the relief pipe.

Get everyone outside, leave switches and appliances alone, and ring 000 or your gas distributor's emergency line from outside. Then call a licensed gas fitter.

If you can isolate it and it isn't spreading, it can generally wait for a daytime booking.

Annoying and wasteful, but not damaging overnight. Put a cloth in the basin if the noise keeps you awake.

Turn off the small isolation valve on the wall behind the toilet. You can still flush once more by pouring a bucket of water into the bowl.

Stop using it and use the other toilet. If it is the only toilet in the house, it moves up to urgent.

A single sink or shower draining slowly, with everything else normal, is a local blockage. Avoid using it overnight.

We still take these calls at night, and with a baby, an elderly or unwell person in the house it may not be able to wait. If yours can manage until morning, our hot water troubleshooting guide covers the safe checks to try first.

A few minutes now saves a night-time call later, or coming home to a flooded house.

It is usually beside the water meter near the front boundary. Old taps seize, and it is better to find that out on a quiet afternoon than with water running across the floor.

The braided hoses under sinks, basins and toilets fail more often than people expect. A hose with rust spots, fraying or a bulge is worth replacing before you go.

If nobody will be home, turning off the two taps behind the washing machine takes the pressure off its hoses while it isn't being used.

Show whoever is minding the house where the main stop tap and the gas meter are, and leave our number where they can find it.

Our call-out fee is $0 at any time, including nights, weekends and public holidays.

The plumber assesses the problem and gives you a fixed price for the work before starting, so you decide whether to go ahead knowing the full cost.

How It Works

01

Shut the water off at the nearest valve, or get everyone outside if you smell gas. Our emergency plumbing page shows where the valves are.

02

Tell us what is happening, the address, and what you have already turned off. Any hour is fine.

03

The plumber looks at the problem on site and gives you a fixed price. Nothing starts until you say yes.

04

The fault is repaired, the water is turned back on, and everything is checked for leaks before we go.

Common Questions

Yes. Our phones are answered 24 hours a day, every day of the year, including weekends and public holidays.

Yes. We answer every day of the year, public holidays included, and send a plumber out for problems that can't wait.

No. The call-out fee is $0 at any hour. You also get a fixed price for the work before anything starts.

Usually not. Turn off the isolation valve behind the toilet and book a daytime visit. Call straight away if water is escaping onto the floor and the valve won't stop it.

If you have another toilet, usually yes: stop using the blocked one and book a weekday visit. If it is your only toilet, or water is coming up in the shower or floor waste as well, call us now.

Your address, what is happening and where, what you have already turned off, and whether water is near any electrics. Mention anything about access too, such as strata parking, a locked gate or pets.
