What Comes First When You Smell Gas?
Safety comes before plumbing. Do these in order, and none of them involve waiting:
- Get every person and pet outside, and keep them there.
- Leave light switches alone, keep phones for outside, and do not start a car near the building.
- Shut the gas off at the cylinder or meter only when that is on your way out and safe.
- Call the gas network's emergency line from outside, then call us once the place is clear.
A leak inside a closed room builds fast, and the source is often a joint buried in a wall or under a floor. That is why we would rather you make two calls from the footpath than one from the kitchen.
How Does a Leak Trace Run?
Once the site is safe, the trace follows four steps.
- 1
Isolate and test
The line is shut off and pressurised so a gauge shows whether gas is escaping and how fast.
- 2
Detector sweep
A gas detector works along the pipe run, pinpointing where the concentration rises.
- 3
Expose the fault
The failing joint, fitting or section is opened up, and the locator confirms the line's path where access is tight.
- 4
Repair and re-test
The fix goes in, the whole run goes back on the gauge to the current standard, and appliances are relit and checked.
The second test is the proof. A gauge reading does not argue, and you should not take anyone's word for a gas line without one.
What Moves the Price of Repairs?
We provide up-front, honest quotes that will always match the final price, should you decide to go ahead.
What shifts the figure:
- Where the fault sits, since a fitting at the meter is far quicker to reach than a joint under a floor or inside a wall cavity.
- How much of the old line fails the pressure test, because one bad fitting and a whole corroded run are two very different quotes.
- After-hours timing, which changes the rate and gets discussed before anyone leaves for the job.

Once the line holds pressure again, new cooktops, ovens and BBQs come under gas appliance installation, and the wider gas fitting page sets out the rest of the gas work.
When we're not the right call: a billing or supply question belongs to your retailer, and a faulty appliance still under manufacturer warranty belongs to the manufacturer. A leak upstream of your meter is the gas network's to repair, and their emergency line is the call for it.
Straight Answers Before You Ring
What should I do if I can smell gas inside my Cessnock home?
Get everyone outside first and keep hands off every switch and appliance. If the bottle or meter tap is easy to reach on the way out, shut it there, then ring the gas network's emergency line from the footpath and (02) 4063 3475 after that.
Do you find leaks in the older cottages around the town centre?
Yes. A lot of the gas work behind the weatherboard and fibro stock near the centre went in generations ago, and fittings that old often seep under modern test pressures. We trace the run, pressure test it and quote the repair before anything is touched.
Does the line get tested again after the repair?
Yes, every time. The repaired section and the rest of the run both go back on the gauge before we relight any appliance, because a fix is only proven when the needle holds steady. You see the result, not just our word for it.
Can a small leak wait until a more convenient time?
No. Every suspected leak is an urgent job, because gas fills a closed room quickly and the fault can hide in a joint you never see. Shut it down if it is safe, get clear of the house and make both calls from outside.
