Common Signs of a Hidden Leak

  • Damp patches or bubbling paint on walls or ceilings
  • Mould or mildew growth
  • Low water pressure
  • Unexplained increase in water bills
  • Hissing or dripping sounds when taps are off
  • Wet or soft ground around the property
If you notice these signs, don’t wait, leaks get worse over time and can cause serious structural or water damage.
