A gas leak is a serious emergency. If you smell gas, hear hissing near a pipe or appliance, or notice higher gas bills for no reason, you must act immediately. Gas leaks can lead to fire, explosions, carbon monoxide exposure and major property damage — and they must only be handled by a licensed gas fitter.

Jayco Plumbing provides rapid-response gas leak detection and repairs across Greater Sydney, 24 hours a day. With more than two decades of gas fitting experience, advanced leak detection tools and full compliance certification, we locate and repair leaks safely, quickly and professionally.

Gas leaks are never something you wait on. We fix them fast — the right way.

    Common Signs of a Gas Leak

    Smell of Gas (Rotten Egg Odour)

    The most reliable sign of a leak.

    Hissing or Whistling Sounds

    Indicates gas escaping from pipes or fittings.

    Higher Gas Bills

    A hidden leak may be wasting gas constantly.

    Weak Flame on Cooktop

    Often caused by low pressure from a leak.

    Flame Changes Colour

    Yellow or orange flame = incomplete combustion.

    Headaches or Nausea Indoors

    Could indicate carbon monoxide exposure.

    Dying Plants Near Gas Lines

    A sign of underground leakage.

    If you notice any of these signs — shut off your gas immediately.

    Common Causes of Gas Leaks

    1. Old or Corroded Gas Pipes

    Copper pipes can wear out over time.

    2. Faulty Appliances

    Cooktops, heaters, hot water systems and ovens may leak if faulty.

    3. Incorrect or Illegal Installation

    A major cause of leaks — especially from unlicensed tradies.

    4. Loose or Damaged Fittings

    Joints and connectors can loosen or degrade.

    5. Damaged Flexible Hoses

    Often found behind ovens or outdoor BBQ areas.

    6. Underground Gas Line Damage

    Movement, age or accidental digging can break lines.

    7. Incorrect Appliance Conversion

    LPG-to-natural gas conversions done incorrectly are dangerous.

    8. DIY Renovation Damage

    People unknowingly drill into concealed gas lines.

    We diagnose the exact cause — then eliminate the risk completely.
