Signs You Have a Hidden Water Leak

How to Spot a Hidden Water Leak in Your Home or Business

A hidden water leak can cause serious damage before you even know it’s there. From rising water bills to mould and damp walls, small leaks often go unnoticed until major repairs are needed.

At Mobile Leak Detection, we specialise in finding and fixing hidden water leaks throughout Gauteng. If you notice any of the signs below, it’s time to book a professional leak detection service.

1. Unexplained Increase in Water Bills

One of the first signs of a hidden water leak is a sudden rise in your monthly water bill – even when your usage hasn’t changed. Leaks from underground pipes or behind walls can waste hundreds of litres a day.

2. Damp or Wet Patches

Have you spotted damp marks on your ceilings, floors, or walls? Wet patches that don’t dry out are a key sign of a leaking pipe, especially if the area feels soft or warm to the touch.

3. Mould or Mildew Smells

Mould and mildew grow in moist environments. A hidden leak can cause constant dampness, creating the perfect conditions for mould growth – and an unpleasant, musty smell inside your home or business.

4. Low Water Pressure

Leaks reduce water pressure in your plumbing system. If you’ve noticed weaker water flow from your taps or shower, especially in just one area of the property, there may be a leak somewhere in the pipes.

5. Noisy Pipes or Dripping Sounds

Can you hear dripping, hissing, or running water when no taps are open? Sounds like these may point to a leak behind a wall, under the floor, or even inside your foundation.

6. Cracks in Walls or Floors

Over time, leaks can cause foundations or walls to shift, leading to cracks. While some cracks are harmless, those combined with dampness or mould may signal water damage from a leak.

7. Water Meter Changes When No Water Is Used

A simple test: turn off all taps, appliances, and water systems, then check your water meter. If it continues to move, there's likely a leak in your plumbing system.
