Tell us what you have noticed, where the issue appears to be and whether it is internal, external or affecting your water supply.

Water Leak Detection Services

A hidden leak can quickly become expensive if it is left unresolved. From damp patches and low water pressure to unexplained water bills, mould growth or visible water outside the property, early investigation can help reduce damage, disruption and unnecessary repair costs.

Moling Experts provide professional leak detection services for residential and commercial properties across the South of the UK. Our team can investigate suspected leaks on external water supply pipes, internal pipework, central heating systems and underground services, helping to identify the most likely cause and advise on the next step.

Where possible, we aim to locate leaks with minimal disruption. Once the issue has been identified, we can advise whether a repair, pipe replacement or trenchless solution is the most practical option.

Signs You May Have a Water Leak

Water leaks are not always obvious. Some leaks show as visible water or damp, while others are hidden underground, beneath floors, behind walls or within heating systems. The sooner a suspected leak is checked, the easier it is to limit damage and plan the correct repair.

Common signs can include:

  • A sudden increase in your water bill
  • Low water pressure or poor flow from taps
  • Damp patches on walls, floors, ceilings or skirting boards
  • Wet or unusually soft ground outside the property
  • Sound of running water when taps are turned off
  • Mould growth, musty smells or persistent condensation
  • Boiler pressure dropping repeatedly on a central heating system
  • Water pooling around driveways, gardens, paths or external pipe routes

If you are unsure whether you have a leak, Moling Experts can assess the situation and recommend the most sensible next step.

How Leak Detection Works

Every property and leak is different, so the investigation needs to be methodical. We start by listening to the symptoms, checking where the issue is appearing and considering whether the likely source is internal pipework, an external water supply pipe, a heating system, water ingress or an underground service.

Depending on the situation, leak detection may involve visual inspection, pressure testing, checking pipe routes and investigating areas where water is likely to be escaping. The goal is to narrow down the source of the problem as accurately as possible before unnecessary excavation or disruption takes place.

Once the leak has been identified, Moling Experts can explain the options clearly. In some cases, a localised water pipe repair may be suitable. In other cases, a replacement water supply pipe or trenchless installation may be the better long-term solution.
