What Is Happening Right Now?

The three gas calls we get most, and what to do first.

Smell inside

You Can Smell Gas Inside

That rotten egg smell near a cooktop, heater or bayonet point. Natural gas collects high, LPG collects low. Do this now: do not switch anything on or off, not even a light. Open a door, get everyone outside, then call from outside.

Smell outside

You Can Smell Gas At The Meter Or Bottles

A smell around the meter box, regulator or cylinders, or stronger outside than in. Often a perished fitting or failed regulator. Do this now: turn the gas off at the meter or bottle valve if you can reach it safely, keep clear, and call. Never hunt a leak with a flame.

An Appliance Smells Or Will Not Light

A cooktop that will not stay lit, a heater that smells when it runs, or hot water gone cold with a smell at the unit. Do this now: turn the appliance off at its isolation valve, ventilate the room, and book a licensed gas fitter rather than relighting it.

How A Gas Leak Plumber Finds It And Fixes It

Gas leak repair in Sydney follows the same three steps, at 2pm and at 2am.

Isolate The Gas

The gas goes off at the meter or bottle first and the area is ventilated. Nothing is switched on or off until the site is safe.

Test And Find It

A pressure test shows whether the installation holds and roughly where it does not. A detector and a bubble test then pin the leak to the fitting.

Gas Leak Detection FAQs

Answer:

If you can smell gas, get everyone outside first and call from outside the house. For a suspected leak inside your property, on your appliances or on your own gas lines, a licensed gas fitter is who you need, and that is what we send. If gas is escaping from the street main or from the meter itself, that part belongs to the network operator and we will tell you so rather than charge you to find out.

Answer:

Do not switch anything on or off, including light switches, and do not use a phone inside the building. Open a door and a window on your way out. If you can safely reach the meter or the bottle valve, turn the gas off there. Then stay outside until we arrive. The six steps are in our guide smell gas in the house? What to do right now.

Answer:

The price depends on what the leak turns out to be, so we do not quote a figure over the phone before anyone has looked. What is fixed is the process: the gas fitter makes the site safe, finds the leak, and gives you one fixed price for the repair before any work begins. During business hours, Monday to Friday 7am to 4pm, there is no call-out fee just to come and look.

Answer:

A soap solution on an exposed fitting will show bubbles, and it is a reasonable first check on something you can see, like a bottle connection. It will not find a leak inside a wall, under a floor or on a buried line, and it cannot tell you whether the whole installation holds pressure. Only a pressure test can do that, and only a licensed gas fitter can legally repair and certify gas work.

Answer:

Yes. A small leak in an enclosed space becomes a large problem over hours, and the smell you notice in a doorway can be much stronger in a cupboard or a subfloor. Gas also displaces air, so headaches and dizziness are warning signs to get out rather than investigate. Treat any gas smell as urgent.

Answer:

Most leaks on visible pipework or an appliance connection are found and repaired in the one visit. A leak on a buried line takes longer, because the section has to be isolated and pressure tested before anything is dug up, and excavation only starts where the test says the fault is.

Answer:

Yes. The licensed gas fitter who carries out the repair pressure tests the installation and issues a compliance certificate for the work. Keep it: it is the record that the gas work on your property was done and tested by a licensed person.

Answer:

Yes, 24 hours a day, 7 days a week across Sydney. A call-out fee may apply after hours and on weekends, and if it does you are told the amount on the phone before anyone is sent.
