Signs You Might Have a Leak

Not every leak shows up as a puddle on the floor. In fact, many start small and stay hidden until they’ve done serious damage. Here are a few common red flags that may signal a hidden leak in your Seven Hills property:
    Unexplained spike in your water bill: If your usage hasn’t changed but your bill has, a hidden leak might be wasting water out of sight. Mouldy smells or musty odours: Dampness behind walls or under flooring can lead to mould growth and unpleasant smells that linger. Peeling paint, bubbling plaster or warped timber: Moisture behind walls is a major cause of surface damage in homes and offices. Water meter running while everything is off: Turn off all taps, then check the meter. If it’s still spinning, water’s escaping somewhere. Wet or soft patches outside: Soggy lawn or sunken ground could mean a burst pipe or underground leak that’s seeping into the soil.
