The brittle old flexible behind the cooktop: tiny part, outsized share of the leaks we find.

Sutherland
Gas does not grade on a curve. A connection is either tested and certified or it is a liability with a warranty problem, so every gas job we do across Sutherland, from a cooktop swap to a full outdoor kitchen line, ends the same way: needle steady on the manometer, appliances burning blue, paperwork done.

Why The Law Keeps Gas Licensed In Sutherland
NSW law reserves every millimetre of gas work for licensed gasfitters, connecting an oven included, because gas fails differently to water. A water mistake stains a ceiling; a gas mistake is a leak you breathe, a fire you host, or carbon monoxide you never smell. It is no coincidence that the leaks we chase most often trace back to a confident handyman and a roll of thread tape.
The licence is not the paperwork, it is the finish line it enforces: the whole installation held against a manometer until the needle stays put, appliances burning correctly with the ventilation they need, work done to AS/NZS 5601, the standard your insurer will ask about if it ever matters. Across Sutherland and the Shire, that gauge test is how every one of our gas jobs ends.
Appliances outliving their standards
A gas appliance can keep working for decades after the standard it was built to has been superseded. Old wall furnaces and unflued heaters are the ones worth attention, because their failure mode is carbon monoxide rather than an obvious fault.
Weatherboard and brick homes from the suburb’s post-war growth still drain through original earthenware lines that crack and sag with age.
If a heater of that vintage is still in service, have it tested rather than assumed. It is an inexpensive check and it is the one category of gas appliance where the risk is genuinely invisible.
A failed appliance is a closed kitchen
For a food business, gas is production. A cooktop out of service is not an inconvenience to schedule around, it is a menu that cannot be served.
In a block the line into your kitchen is usually the end of a service other homes depend on, so isolating, testing and proving that section still holds is part of even a simple cooktop swap.
So we carry the common commercial failure parts and we work to your service times rather than ours. Where a part genuinely has to be ordered, you will hear that immediately along with what can be kept running in the meantime.
Pool and outdoor heating near the water
Ventilation and clearance clauses were not written with small apartment kitchens in mind, and they regularly rule out the position people assume will work. We establish a compliant location first.
Pool heaters, outdoor fires and alfresco appliances are common on waterfront properties, and they are the largest gas loads most homes ever add. A pool heater alone can exceed the rest of the house combined.
So the first question is never the appliance, it is whether the meter and the run can carry it. That gets established before anything is ordered, because the alternative is an expensive heater that never reaches temperature.
Gas in an apartment: what is yours
In a block, the supply to the building and the risers are common property; the pipework and appliances inside your lot are generally yours. Individual meters may sit in a common meter room, which frequently confuses the question of access.
Establish it before arranging work. Anything on common property needs the owners corporation to authorise it, and a plumber cannot simply proceed because a resident asked.
Whole streets, one vintage
Where an area went up in a single wave, its gas installations date from that wave too. Neighbours comparing notes about the same faults are usually right that there is a pattern.
That is useful context rather than cause for alarm. It means a test on your installation is informative about more than your house, and it is worth doing before any renovation adds load to it.
Ventilation, flues and living close to the water
Homes near the water are often closed up tighter against wind and weather than their inland equivalents, and modern draught-proofing has made that more pronounced. Gas appliances need air, and a well-sealed room changes the ventilation calculation.
It matters most for older heaters and anything unflued. If a room with a gas appliance has been renovated to be more airtight, the appliance should be re-assessed for that room rather than assumed still suitable.
What a blue flame is telling you
Correct combustion is blue and steady. Yellow, lazy or lifting flames mean the air-to-gas ratio is wrong, a blocked jet, a starved supply, insufficient ventilation, or an appliance set up for a different gas type.
It is the one diagnostic anyone can do without equipment, and it is worth a look at every gas appliance in the house once a year.
What it costs in Sutherland
Joints & fittings, $200–$600
Thread and valve leaks sealed properly and proven again on the gauge.
Pipe runs, $400–$1,500
Corroded or damaged sections replaced; concealed lines with access work run $800–$2,500.
Appliance connections, from ~$200
Connected, tested, certified. New line or bayonet to reach it quoted fixed on top.
The market rate, $120–$220/hr
Sydney's 2026 licensed-gasfitter range; attendance typically $80–$150. Certification is included, because without it there is no job.
The receipt that matters is not paper: it is the needle on the manometer refusing to drop. Figures here are indicative of the 2026 Sydney market rather than a quote from us, you get your own number as a fixed price before any work starts.
Anatomy Of A Gas Job
Step 01
Step 01
Isolate Before Anything
Suspected leaks start with the supply off at the meter and air moving through the space. Diagnosis begins only after the installation stops feeding the problem.
Step 02
Let The Gauge Accuse
A manometer says whether the system is losing gas; detection fluid and instruments then walk the installation to the guilty joint, fitting or run.
Step 03
Replace, Never Bodge
The failed component comes out and compliant material goes in, to AS/NZS 5601, whether that is one connector or metres of rerun line.
Step 04
Prove, Relight, Certify
The full installation holds on the gauge or we are not done. Appliances relit, flames checked blue, ventilation confirmed, compliance documented.
New Appliance Still In Its Box?
New cooktop in its box, a bayonet that needs moving, or a smell you are not sure about: call and it gets done properly.
The installation is isolated, brought to a set pressure and watched on a manometer for a defined period. If the needle holds, the system is tight; if it drops, gas is escaping and the test indicates roughly how much. It is the only way to know the condition of pipework you cannot see.
Leave the building and take everyone with you. No light switches, no appliances, no phone calls made inside: a switch operating is an ignition source. From outside, ring 131 909, the gas network's emergency line, staffed around the clock. They attend and make the supply safe at no cost to you.
Indicatively: a pressure test and leak location $220-$450; a new bayonet or appliance point $350-$800 depending on the run; an appliance service $180-$320; a cooktop changeover $250-$500 where the point already exists. Market figures for 2026, not a quote, and every job includes the compliance certificate rather than adding it.
Unlikely. Where an area went up in one wave, its gas installations date from that wave too. It is useful context rather than cause for alarm, it means a test on your installation is informative about more than your house, and worth doing before any renovation adds load.
Substantially. Interlocked ventilation, larger loads, appliance isolation requirements and inspection obligations that fall on the operator. The practical consequence is that a commercial installation cannot be extended casually, adding a wok burner changes the load, the ventilation calculation and the certification together.
It can. Gas appliances need air, and modern draught-proofing changes the ventilation calculation for a room. It matters most for older heaters and anything unflued, if a room with a gas appliance has been renovated to be more airtight, the appliance should be re-assessed for that room rather than assumed still suitable.
Same procedure, more urgency: a leak on a shared riser affects everyone on it. Leave, take others with you, ring 131 909 from outside, then notify the building manager. Do not attempt to isolate anything in a common meter room yourself.
