    Act Early, Prevent Damage

    Early Water Leak Warning Signs

    Water leaks often begin unnoticed but can quickly lead to serious structural damage, mould growth, and rising repair costs. Acting early helps protect your property and reduces the risk of long-term issues. Our team focuses on identifying leaks at the source and resolving them before they escalate.

    Hidden leaks can develop behind walls, beneath floors, or underground, making them difficult to detect without proper equipment. Knowing what to look for can help you take action sooner and avoid major disruptions.

    • Sudden or unexplained increase in water bills
    • Damp patches on walls, ceilings, or flooring
    • Sounds of running water when no taps are in use
    • Mould growth or persistent musty odours indoors

    Great service and excellent work Recommend them
    Melanie Carroll
    We had a major leak at our property and WSG Group were fantastic from start to finish. They organised leak detection, located and isolated the leak quickly, and kept us well informed throughout the whole process. Communication was excellent, the quote was clear and reasonable, and they were very flexible with arranging the work around us. Everyone we dealt with was friendly, professional and helpful, which made a stressful situation so much easier. The repair involved digging underground to access the leak, and they did a great job restoring the area afterwards. They left the site clean and tidy and repaired the section they had to remove, which we really appreciated. We’re extremely happy with the service and workmanship and would definitely recommend WSG Group to anyone needing a reliable plumber. Thanks again!

    They were both very professional & knew what they were doing, as well as friendly & letting me know what they were doing. Insurance job.

    Shout out to the professionalism of WSG's Jake Duncan and his team redesigning and repairing a roof that was built below Australian standards by a local Central Coast builder. This caused us a lot of heartache but now there is peace of mind. Highly recommend.

    Jail was excellent in finding the issue with one of my cctv cameras. Fixed quickly and he also installed my replacement ceiling fan in the bedroom. No mess left behind either. I would highly recommend this mob.

    We had a dishwasher replacement which turned out to be not so straight forward as we thought. Due to the fact that the replacement dishwasher was a different brand to the one being replaced & therefore slightly different dimensions. Our dishwasher has a cupboard door front to match the kitchen cupboards & it proved to be quite challenging to fit. We want to thank the young man who was given the challenge do this job, his name is Jonty & he was a joy to have in our home. He is polite, friendly,engaging & thorough with his work, he’s the type of young man that we felt safe with & to us that’s an important characteristic. We’d also like to thank Dean who came out this morning to check that we were happy with the job & that it was installed to perfection & also to run us through the mechanics of our new dishwasher . He was also very affable, thorough & someone that we were happy to have in our home. We are elderly & these attributes are rare these days sadly. To the manager of the WSG GROUP, these young men are a credit to your company & a credit to society in general. Thank you for your service. Gail & Ron Reed.
