5 Signs of a Hidden Water Leak in Your Home

Hidden water leaks are more common than most homeowners realise—and the longer they go undetected, the more damage they can silently cause. From structural issues to mould growth and sky-high utility bills, a small leak can quickly become a major problem. At Sweeney Property Services Donegal, we specialise in locating leaks quickly, accurately, and without unnecessary damage. Here are the top signs to look out for.

1. Unexplained Increases in Your Water Bill

If your bill suddenly rises without any change in usage, there’s a good chance water is escaping somewhere. A professional leak detection survey can pinpoint the exact source.

2. Damp Patches or Mysterious Stains

Patches on walls, ceilings, or floors often indicate water travelling from pipes hidden behind surfaces. Thermal imaging is one of the most effective ways to trace the path of moisture before major damage occurs.

3. Mould or Musty Odours

Persistent dampness encourages mould growth, which can affect both your property and your health. Identifying the root cause is more effective than simply cleaning it away.

4. Reduced Water Pressure

A drop in pressure typically means water is escaping along the way. Leak detection equipment can quickly locate the issue before the pipe fails completely.

5. Sounds of Running Water

If you hear water running when no taps or appliances are in use, it’s time to investigate.
