Signs you have a gas leak at your home or business

You can smell gas

It is not normal to smell gas inside or outside your house, so if you notice a gas or rotten egg type smell then it could be a leak, which needs an immediate fix.

You can hear a hissing sound

A hissing sound near your gas appliance or gas line could also indicate a hole or crack somewhere that is causing the noise and the leak.

Deteriorating Vegetation

If the vegetation around your home suddenly looks discoloured or close to dying, it could be because carbon monoxide is replacing the oxygen needed by plants to survive.

Bubbling in Wet Flooded Areas

Gas leaks in an underground or concealed pipe will likely trigger bubbles in wet flooded areas, indicating an emergency issue that needs a quick, professional fix.

If you have said yes to one of these signs, call your local gas plumber at GSM Plumbing immediately

Gas Appliance Installation Checklist

Here's a checklist if you're thinking about installing a gas appliance in your property:

Contact your gas retailer & make sure gas is available at your property

Your first step is to make sure you have gas at your property, which you can do by contacting your gas retailer or your strata manager if you live in a strata property.

Decide on where you would like your appliance installed

Next, have an idea of where you want to install your stove. We can help you identify the best location based on underground gas piping, exhaust requirements and more.

Choose appliances/outlets for a gas connection

This is a good time to consider other gas appliances like fixed gas heaters, gas hot water systems, alfresco gas outlets and living room gas outlets, so you complete your installation needs in one go.

Get an on-site inspection and fixed price quote by our qualified plumbers

An on-site inspection helps us understand your specific needs so we can give you a transparent, fixed price quote with absolutely no hidden costs or call-out fees.

Why You Need A Gas Compliance Certificate

A gas compliance certificate is a guarantee that covers the following:

Your gas fitter has the appropriate qualifications and licenses to perform this type of work
Completed work has been tested and safe for your house or business to use
All work meets legal requirements and Australian Standards
The job has been legally recorded

If any gas-related work has been completed on your property, you are entitled to receiving a Gas Compliance Certificate within 30 days. This includes installation of new gas pipelines, repairing existing gas pipelines, along with installation, replacement and repair of gas appliances like hot water systems, stoves, ovens and heaters.

The Gas Compliance Certificate lets your gas supplier know that a licensed gas fitter has completed the job, making it safe and legal to supply gas to the property. It is extremely important to note that insurance companies will not cover issues like public liability claims and fire caused by unlicensed or DIY gas appliance or pipeline installations.

The gas fitting team at GSM Plumbing have the qualifications, training and licenses to comply with all legal requirements – ensuring we test and certify any gas installation, repair or replacement to keep everyone on your property safe.

Why does natural gas smell so bad?

Natural gas itself is colourless and odourless, which is why a harmless chemical is added to it to give it a distinctive odour that resembles a rotten egg. Despite the nasty smell, it is designed to keep you and your property safe, allowing you to notice and get a gas leak professionally fixed immediately to prevent any catastrophes in your home or office.

Can you install gas appliances?

Yes, we can install any gas appliance if you have a gas line connected to your house. If you need a gas line from your house connected to the main line on your street, we can do that too. If there is no gas on your street, we can install LPG bottles if needed. Just give us a call with your questions and we’ll answer them for you.
