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 gas 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 leak detection 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 premises, which you can do by contacting your gas retailer or your strata manager if you live in a strata complex.

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.

We lived in Castle Hill for many years, and it has always been challenging to find a good and reliable local plumber until we met Greg. Greg is knowledgeable and easy to deal with. More importantly, unlike other plumbers who try to rip you off or take advantage of the situation, Greg's prices are very competitive compared to similar work. Greg is our number 1 go-to man in the Hills District.

I called GSM plumbing to discuss the stormwater drainage needs. Greg was quick to come over and explained the proposed plan in depth. He also went to the lengths of explaining how I should plan the different ongoing renovations to save time & money overall. I found him very honest and direct and will surely book him for any future plumbing work. Good bloke.
