Frequently Asked Questions

  • How do I know if I have a hidden water leak at home?

    Hidden leaks often show subtle signs before becoming major issues. Common indicators include unexplained increases in water bills, damp or discoloured patches on walls or ceilings, musty odours and reduced water pressure. You may also hear water running when no fixtures are in use. 


    In some cases, cracks in walls or flooring can appear due to prolonged moisture exposure. Because many leaks occur behind walls, under floors or underground, they are not always visible. 


    If any of these signs are present, professional leak detection can accurately identify the source before significant damage occurs.

  • Is leak detection non-invasive?

    Modern leak detection methods are typically non-invasive, meaning there is no need to dig up floors or break through walls unnecessarily. Specialists use advanced equipment such as acoustic sensors, thermal imaging and moisture meters to pinpoint the exact location of a leak. This approach helps minimise disruption to the property while still delivering highly accurate results. 


    Non-invasive techniques not only protect the structure of the home but also reduce repair costs and time, making them a preferred option for homeowners dealing with suspected leaks.

  • Can a water leak cause structural damage?

    Yes, even a small, undetected leak can lead to serious structural damage over time. Continuous exposure to moisture can weaken timber, corrode metal components and compromise the integrity of concrete foundations. It can also lead to mould growth, which poses health risks and further damages building materials. 


    If left untreated, what starts as a minor issue can result in costly repairs, including replacing flooring, repairing walls or addressing foundation problems. Early detection is key to preventing long-term damage and maintaining the safety and value of the property.

Signs You May Have A Leak

Water leaks can be tricky to spot, but ignoring them can lead to structural damage, rising water bills and mould growth. Knowing the early warning signs helps you act quickly and avoid costly repairs before the issue worsens.


The symptoms of a leak include:


  • Unexplained water bills: A sudden spike in usage without changes to your habits may indicate a hidden leak.
  • Damp spots or discolouration: Marks on walls, ceilings or floors can signal water leaking behind surfaces.
  • Unusual sounds: Hearing water running when taps are off could point to an issue within your pipes.
  • Low water pressure: A noticeable drop in pressure may suggest a leak in your plumbing system.
  • Mould or mildew smells: Persistent damp odours often mean moisture is building up where it shouldn’t.
