Professional Leak Detection with In-House Plumbing Repairs

We understand that every leak is different. Some are easy to spot, while others are hidden behind walls, beneath concrete, or underground. Our proven process begins with a site inspection by our licensed plumbers. If the leak is not immediately visible, we escalate the investigation to our trusted leak detection partner who uses ultrasonic listening devices and other specialised tools to locate the exact source.

Our priority is always to keep costs down and avoid unnecessary procedures. That is why we only involve leak detection technicians when absolutely necessary. If your issue can be resolved with a simple repair, we make it happen straight away.

We do more than just detect leaks – we repair them. LJM Plumbing is known throughout Brisbane for combining accurate water leak detection with prompt and effective plumbing services. While many companies subcontract both detection and repair, we keep repairs in-house to ensure quality, speed, and reliability.

Once a leak is located, our team completes the repair using durable materials and industry-standard techniques. Whether it's a leaking pipe in the wall, a burst underground main, or water ingress from an unknown source, we guarantee long-term solutions, not temporary fixes.

Our in-house equipment includes concrete saws, plumbing tools, earthmoving machinery and leak testing devices. This allows us to act fast without waiting on subcontractors or third-party service providers. Our 24-hour availability means we can respond to emergencies and prevent further water damage at any time.

    I've used LJM for years and am always very satisfied and grateful for their work. I've had a couple of jobs this year (thanks to Greg, Ethan, Jack, Andy and Danyelle) which are always scheduled promptly. The plumbers always turn up on time or early, are clear with all communication and advice, friendly, polite, and well mannered. The team is such a delight to deal with, and so rare to receive the standard of service LJM consistently delivers these days. Thank you!!

    I had Ethan from LJM Plumbing and Drainage come out today to fix a leaking shower, and I’m so impressed with the service. After a bad experience with another plumber who was going to rip me off, Ethan was a breath of fresh air. He was honest, professional, and very courteous. He fixed the problem quickly and explained everything along the way. I would definitely use them again and highly recommend them to anyone looking for reliable plumbing.
