Water leak detection - How do you find a leak you can't see?

You cannot unless you are using special equipment. We always say, even a plumber will not be able to help without tools. They might be able to ”locate” by their knowledge, and experience, but it cannot be 100% located without tools seeing through the walls.


If you suspect you have a leak, here is what you can do as a homeowner.

  • Check your usage regularly.
  • Check the bills regularly.
  • Check for damps, watermarks or leaks.

Our leak detection includes disruption provide photographic reports.

Hidden leaks cannot be found without special equipment, however. However, if the source of a water leak is hidden, leak detection specialists are a better option.

Leaky water pipes can have several detrimental effects. So it must be your goal to resolve any suspected leaks as fast as possible. Various visible markers will help locate leakages in the house. A typical sign is a damp spot on walls or pools of water near a place of unknown origin, the sound of dripping water from walls, discolouration of walls or ceiling etc. But leaks found in walls can sometimes be difficult to detect. Prices may vary in each part of the UK, depending on the method used, but in London, an average cost for a special leak detection team is around £90-£220 + VAT/hrs.

Thermal imaging cameras can’t distinguish moisture within the wall, however, they can find the subtle temperature differences and patterns to discover the existence of water. Is using an infrared camera for water leak detection effective? Yes, using an infrared camera to find a water leak is incredibly effective because it senses and translates the radiation emitted by objects into thermal pictures. Very successful water leak detection services can be carried out.
We have found leaks that have been running for more than 10 years that other leak detection companies and water authorities failed to find.
