Professional leak detection for annoying hidden plumbing problems

Not every plumbing leak is easy to spot. Some leaks happen behind walls, under floors, in ceilings or underground, where the signs may not be obvious at first.
You might notice damp patches, mould, stained surfaces, low water pressure or a water bill that suddenly seems too high. In some cases, you may hear water running when nothing is turned on.
Service Today helps homeowners investigate hidden water leaks, identify the likely source and understand what needs to happen next.

Signs you may have a hidden water leak problem

Some leaks stay hidden for a long time before they are discovered. The earlier the issue is identified, the better the chance of reducing further damage and unnecessary water loss.

Common signs can include:

Unexpectedly high water bills
Damp patches on walls, ceilings or floors
Mould or mildew growth
Reduced water pressure
Water stains or discolouration
The sound of running water when nothing is in use
Warm or wet spots on floors
A leak that cannot be easily located

Why hidden leaks should not be ignored

Even a small hidden leak can lead to bigger problems over time. Water can damage walls, ceilings, floors, cabinetry and surrounding materials, and ongoing moisture can create conditions for mould or structural deterioration.

In some homes, a concealed leak may also waste a significant amount of water before the problem is found. That is why it is worth investigating early rather than waiting for clearer damage to appear.
