Gas Leak Detection & Repairs Sydney

Smell gas? Get everyone outside and call the gas emergency line from outside first. Then our licensed gas fitters find the leak, repair it and test the system.

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

A gas leak needs a licensed gas fitter. Our licensed gas fitters test your gas installation for leaks, track down where the gas is escaping, whether that is a fitting, a connection behind an appliance or the pipework itself, and repair or replace the faulty part. We test again before the gas goes back into use. We also test gas connections for leaks whenever we connect an appliance. You get a fixed price before we start the repair. Licence 347993C.

Gas leaks are a safety issue before they are a plumbing one. Do these in order, and only what you can do safely.

Don't light anything, and don't turn lights, appliances or power points on or off. A switch can spark.

If you can reach the gas meter on your way out, turn the valve a quarter turn so the lever sits across the pipe. If the smell is strong, don't stop to do it.

Leave the doors open on the way out if you can, and keep everyone away from the house.

For natural gas in Sydney, call Jemena's faults and emergencies line on 131 909. If you use bottled LPG, call your gas supplier. If anyone is unwell or you think there is immediate danger, call 000.

Once it is safe, the leak has to be found and repaired by a licensed gas fitter before the gas goes back on.

Gas has a rotten egg odour added so that leaks can be noticed. If you can smell it, take it seriously.

A hissing sound near a gas pipe, meter or appliance can mean gas is escaping.

Dead plants over a buried gas line, or a gas bill that has jumped for no obvious reason, are worth getting checked.

When we connect a gas appliance, we test the connection for leaks before we leave. On a recent job in Greystanes we replaced a cracked gas cooktop and tested the gas connection for leaks.

In NSW, gas work must be done by a licensed gas fitter. Don't try to fix a gas leak yourself.
