Sydney's Trusted Leak Detection & Inspection Specialists

A hidden leak is one of the most damaging plumbing problems a home or business can face. Whether it’s behind a wall, under concrete, inside a ceiling or somewhere in your drainage system, water leaks can go unnoticed for weeks — causing structural damage, mould, rising damp, high water bills and costly repairs.

Jayco Plumbing provides professional leak detection and inspection services using industry-leading equipment and more than two decades of hands-on plumbing experience. We locate leaks fast, accurately and without unnecessary damage to your property.

If you suspect a leak, don’t ignore it. Early detection saves thousands.

    Common Signs You Have a Hidden Leak

    • Sudden spike in water bills
    • Damp walls or bubbling paint
    • Mould or musty smells
    • Dripping sounds in walls or ceilings
    • Warm or wet patches on the floor
    • Water stains on ceilings
    • Cracks in walls
    • Toilet running constantly
    • Low water pressure
    • Soil or garden areas always wet
    • Moving water meter when taps are off

    If you notice any of these, you likely have a leak.

    What Causes Hidden Water Leaks?

    • Ageing or corroded pipes
    • Poor installation from previous plumbers
    • Tree root intrusion
    • Bathroom waterproofing failure
    • Movement in concrete or foundations
    • High pressure in pipes
    • Faulty connectors and joints
    • Damaged stormwater lines
    • Incorrect drainage falls
    • Broken toilet seals
    • Underground pipe fatigue

    These issues can range from small drips to major bursts.
