From new gas installations to appliance servicing and compliance certification, our fully licensed team handles residential, strata and commercial gas work to Australian Standards and NSW Fair Trading requirements.

Our Gas Fitting Sydney Services

• New gas installations — complete system setup from the street connection through to your appliances, for new builds, renovations and conversions.
• Gas appliance installation & servicing — cooktops, ovens, heaters and gas units, installed and maintained by licensed gas fitters.
• Gas leak detection — advanced electronic and pressure-testing equipment to accurately pinpoint leaks before they become a safety issue.

• Strata gas services — ongoing gas testing and reporting for unit blocks and strata buildings across the Eastern Suburbs.

Signs You Need a Licensed Gas Fitter

Not every gas issue is obvious. Call a licensed gas fitter if you notice the smell of gas near an appliance or meter, a pilot light that keeps going out, scorching or soot marks around a gas unit, a hissing sound near gas pipework, or if your last compliance certificate has expired. Gas work in NSW must legally be carried out by a licensed gas fitter — DIY repairs on gas appliances or pipework are illegal and dangerous.

Gas Compliance Certificates Sydney

Whether it’s a rental turnover, a pre-sale requirement, or a routine safety check, Sterling Gasfitting & Plumbing issues gas compliance certificates for every new installation or modification, meeting strict NSW Fair Trading and Australian Standards requirements.

Our compliance service covers gas safety inspections and pressure testing, appliance safety checks, fast turnarounds for real estate deadlines, and strata and heritage property assessments.

How the Gas Compliance Process Works

• Book an inspection — call or message us with your address and the reason for the certificate (sale, rental, renovation or routine check).
• On-site inspection — our licensed gas fitter checks all gas appliances, pipework, flues and ventilation against Australian Standards.
• Pressure testing — we pressure test the gas system to confirm there are no leaks.
• Certificate issued — once everything passes, we issue your compliance certificate, usually within 24-48 hours.

Sterling Gasfitting & Plumbing provides leak detection Sydney homeowners, landlords and strata managers call on when a hidden water or gas leak needs finding fast. Hidden leaks cause real damage if they go unnoticed — rising water bills, damp walls, mould, and in the case of gas, genuine safety risk. We use non-invasive detection technology to find the source fast, without unnecessary demolition.

Our Leak Detection Sydney Methods

• Thermal imaging — spotting hidden leaks behind walls, under floors and within slabs without cutting into them.
• Acoustic & electronic pipe locating — specialist listening equipment to pinpoint underground and in-wall leaks precisely.
• Nitrogen pressure testing — isolates and confirms leak locations in gas and water lines.
• Trace gas testing — advanced detection for leaks that don’t show up through standard methods.
• Moisture detection — identifying water ingress behind walls and under flooring before it becomes structural damage.

Signs You May Have a Hidden Leak

An unexplained rise in your water bill is often the first clue, even when no leak is visible anywhere on the property. Other common signs include damp or discoloured patches on walls and ceilings, a musty smell that won’t go away, the sound of running water when every tap is off, or a gas smell near an appliance or meter. Strata buildings should also watch for unexplained dampness in common areas or the floor below a bathroom or kitchen.
If you smell gas, the safest first step is to turn off the gas supply at the meter if it’s safe to do so, avoid using switches or naked flames, ventilate the area, and call a licensed gasfitter immediately rather than waiting to see if the smell clears on its own.

2. On-site investigation — we use thermal imaging, acoustic listening and pressure testing to narrow down the source.
3. Confirmed location — we pinpoint the leak before any cutting or digging begins.

Common Hot Water Repairs We Handle

No hot water, water that won’t stay hot, a leaking tank, a pilot light that won’t stay lit, unusual noises from the unit, or inconsistent temperature are the faults we see most often on hot water repairs Sydney-wide. Most calls are diagnosed and quoted on the spot, with many repairs completed same visit using genuine parts.

Keeping Your Hot Water System Running

A few simple habits extend the life of any hot water system and reduce the chance of an unexpected breakdown. Annual servicing lets a licensed technician check the anode, pressure relief valve and thermostat before small issues become expensive ones.

This is especially important for gas systems, where a poorly maintained unit can also raise safety concerns. Storage tank systems typically last 8 to 12 years depending on water quality and usage, while continuous flow units can run longer with regular servicing.

If your hot water system is over a decade old and starting to make noise, run out of hot water faster than it used to, or show rust-coloured water, it’s worth having it inspected rather than waiting for a full failure.
