Gas Appliance Installation for Homes and Businesses

Gas Leak Detection and Urgent Repairs
Gas leaks must be found and fixed straight away to keep your household or workplace safe. Our certified gas fitters use advanced tools for gas leak detection in your gas pipe, fitting, or connected appliances.
Once we’ve isolated the issue, we do gas leak repairs or replace damaged components and carry out full system testing before restoring your supply.
We’re ready to help if you need emergency gas repairs, and we make safety our first priority every time.
Gas Hot Water System Services
Our gas plumbers install, maintain, and repair gas hot water systems, including storage tanks and continuous flow models. We handle all connections, flue fittings, and compliance checks to ensure reliable, consistent hot water.
If your hot water gas system isn’t working properly, our team will diagnose faults and put things right promptly. We can also talk you through replacement options if it’s time for an upgrade.
Gas Compliance Certification and Safety Inspections
After any major gas work, you’ll often need compliance certification. Our gasfitters are qualified to carry out safety inspections, pressure testing, and issue the right paperwork required by insurance or for property sales.
We give you confidence that your gas set-up is up to code and safe for daily use.

Signs You Need Gas Fitter Services
When it comes to gas safety and system reliability, knowing the early signs of trouble makes all the difference. Our team at JSW Plumbing has seen just how quickly a small issue can become a safety concern. Here’s what to look for if you suspect you need a gasfitter.
Persistent Gas Smell at Home
Any unusual smell of gas, inside or out, is a direct signal that something isn’t right. In Australia, natural gas is given a strong odour so you can detect even a minor leak.
If you notice this sulphur or rotten egg smell near appliances or pipework, it’s an urgent situation.
Our gasfitters use precise leak detection methods to find and resolve leaks quickly and safely, meeting all Thornleigh and NSW regulations.
Issues With Gas Appliance Flames
When the blue flame on your gas heater or gas cooktop turns yellow or orange, it means the gas isn’t burning cleanly. This points to blocked jets, a build-up inside burners, or even low pressure in the line.
These problems do more than impact performance; they create risks of carbon monoxide exposure or fire. Our gasfitters can repair or service any gas appliance to ensure complete combustion and safe operation every time.
Visible Pipework or Appliance Damage
Rust, pitting, corrosion, or visible cracks in gas pipes or fittings should never be ignored. Thornleigh’s climate can speed up this kind of wear, especially near older pipe runs or exposed joints.
Our team carries out thorough inspections and targeted repairs, providing detailed compliance certification as required under NSW law for any gasfitting service.
Unexplained High Gas Bills
If your usage jumps suddenly, and there’s no clear reason, undetected gas leaks or faulty appliances are often the hidden cause. Our local gasfitters use specialised testing tools to check lines and appliances.
We provide full reporting, so you know exactly what’s happening and what’s been done to correct it.
If you notice any of these signs in your property, our team at JSW Plumbing is ready to help. Reach out, and we’ll handle your gasfitting needs with care and expertise.
Why You Should Get Gasfitting Services
Proper gasfitting brings both immediate and long-term value to homes. Our team at JSW Plumbing focuses on safety, compliance, and durability with every gas-related job.
Here’s how a qualified gasfitter protects your property and peace of mind from day one.
Safety, Risk Management, and Compliance
A licensed gasfitter ensures all gas systems in your home are installed and maintained according to Australian standards. This greatly lowers the risk of leaks, fire, and carbon monoxide exposure.
In Thornleigh, only certified gasfitters can legally carry out gas work, offering homeowners protection from hazards and legal penalties. We provide compliance certificates for every job, essential for insurance, future property sales, or rentals.
Ongoing System Assessment and Preventive Maintenance
Regular checks from a skilled gasfitter pick up early signs of wear, corrosion, or leaks. This saves you from unexpected breakdowns and costly repairs down the track.
JSW Plumbing doesn’t just react to problems, we help you avoid them altogether with a maintenance-first approach that improves appliance life and system reliability.
Insurance, Legal Requirements, and Financial Security
Gas systems must meet strict codes, and insurance providers often insist on documented, compliant gasfitting. Unauthorised work not only leads to heavy fines but can also void your insurance.
Our gasfitter service delivers all required paperwork so your property stays covered and your costs stay predictable.

With JSW Plumbing, you have direct access to local gasfitters who know Thornleigh’s rules and house types. We guide you on appliance use, maintenance, and recognise issues before they escalate.
A relationship with our team means ongoing support if you ever need upgrades or urgent help.
