What to Do in the First Few Minutes
Safety comes before any diagnosis. Do these things in order:
- Get people and pets outside and keep well clear of the building.
- Do not touch light switches, power points or anything that can spark.
- Shut the meter tap off if the meter is accessible and you can do it safely.
- Open doors and windows on your way out if it takes seconds, not minutes.
- Ring the gas network's emergency line, then call us.
Do not go back inside until the supply has been made safe. Once the network has isolated the leak, we trace the fault on your side of the meter, repair it, and test the whole run before restoring the gas.
How Do We Find a Hidden Leak?
Gas leaks hide in the places you least want to pull apart: under floors, inside wall cavities, along buried runs to BBQ points and pool heaters. Guessing means opening up the wrong wall, so we work by instrument instead.

The Repair, Step by Step
- 1
Make it safe
The supply is isolated at the meter before any fitting comes apart.
- 2
Trace and confirm
The detector and the pressure test agree on where the leak is before we open anything up.
- 3
Repair or replace the section
A failed joint gets remade; a corroded or damaged run gets replaced with new-rated pipe, and we fit coastal-rated fittings where the exposure calls for it.
- 4
Test and certify
The full line is pressure tested again, every appliance is checked, and the supply is restored only once the readings are clean.
What Decides the Final Cost?
We provide up-front, honest quotes that will always match the final price, should you decide to go ahead.
It costs nothing to get us out to your door (excluding after-hours).
The main drivers are:
- Where the leak sits A fitting behind the cooktop is a short job; a buried run under the driveway means locating and excavating.
- The age of the line Older runs sometimes fail at more than one point, and if the line is beyond a sound repair, replacing the section is the honest option.
- Access Under-floor crawls, tight side passages and roof-space runs all change the time the job takes.
- What the repair needs in parts Valves, regulators and pipe are quoted at cost before we start.
Gas Runs From Another Era
Old lines, slow weeps. Plenty of homes near St Augustine's, where Windsor and Llewellyn Streets meet, date to the Federation and inter-war eras, and some still carry gas runs fitted decades ago with fittings from their own era.
A joint that has held for sixty years rarely fails loudly. It weeps, the smell builds on still days, and the problem only shows when someone lights the cooktop. We check the whole run rather than patching the one fitting that announced itself, because the next-weakest joint is rarely far away.
"We had an urgent gas problem that required immediate attention at our home…on a Friday afternoon. … Identified the issue, fixed and tested" Lee
When We're Not the Right Call
If the smell is coming from the street side of the meter, from a main in the road reserve, or from a neighbouring property you cannot access, the gas network owns that fault and their emergency line is the first call. And if the leak involves an appliance still under another fitter's warranty, ring them first so you keep that cover intact.
Gas Leak Questions We Get
Everything above covers the practical side. Here are the questions that come up most often on the phone.
What should I do first if I smell gas in Merewether?
Move everyone outside, leave switches and appliances alone, and shut the meter tap if it is safe to reach. Ring the network's emergency line first, then call us to trace and repair the leak on your side once the supply is safe.
Can you find a leak that only smells some days?
Yes. Electronic detectors and pressure testing pick up intermittent leaks, including slow weeps on buried runs or behind appliances that only show on still days or when the line is working hard.
Do you work on gas lines in the older cottages?
We do. Plenty of older Glebe homes still carry gas runs from their own era, so we check the whole line rather than patching the fitting that announced the problem.
Do you attend a suspected gas leak after hours?
We do. A suspected leak should never wait for morning, and we are available 24/7. Ring (02) 4063 1093 at any hour and we will walk you through the immediate safety steps.
Back on the Gas Side of the House
Once the leak is sorted, it is worth having the rest of the gas work checked over. Our gas fitting hub covers the full range, including gas appliance installation for cooktops, heaters and BBQ points. If it turns out the problem is water rather than gas, water leak detection is a separate service, and emergency plumbing covers burst pipes and overflows at any hour.
