24/7 On Call Anytime

Available 24/7, we can get to you quickly whether it is early in the morning or late at night.

Emergency Blocked Drains

A blocked drains emergency can occur at the most inconvenient time and is often caused due to hair, food waste or toilet paper clogs. We are well prepared to resolve your issue, day or night, with specialist tools like CCTV cameras, high-pressure water jets, drain snakes and more to prevent it from overflowing and causing massive damage to the structure of your home.

Emergency Hot Water Repairs

We know how much you depend on hot water especially if the temperatures plummet outside, which is why we provide emergency hot water assistance to fix any issues in no time. Just give us a call and we can find a repair or replacement solution that minimises disruption to your life.

Emergency Burst Pipe Repair

A burst pipe should never be ignored because of the potential damage it could cause to the structure of your home. In an emergency, we ask you to turn off the main valve to cut off water supply until we get there as quickly as possible.

Emergency Gas Plumbing

Gas appliances are a great, cost-effective choice for many homeowners, but if you notice a gas leak or any other issue, call our emergency gas plumbing team so we can arrive at your doorstep straight away to fix the problem. Never ignore a gas emergency because it could have catastrophic consequences.

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.

Greg came out to look at my stormwater drainage issues today, only an hour after I called, was very helpful, professional and genuinely interested in working with me to find a cost effective and effective solution to my issues. He advised a possible solution that would both solve my issue and save money. Thanks Greg, look forward to working with you in the next few weeks to solve my drainage issues.

Greg and his team when called and offered prompt and professional service to repair and restore all Flexi hoses and install taps quickly after a major flooding drama. No job too small and always helpful.

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.
