Using our plumber’s expertise, you are receiving a professional, quick leak detection service. We are proud to serve across North London, and save them from major water damage.

More about thermal imaging camera leak detection!

The camera detects temperature by recognizing different levels of infrared light. Hidden water behind the walls can be found without even a cut. It can detect the temperature differences inside the wall or a floor. The wall and floor must be room temperature, between 18-21. If you have underfloor heating, it can rise by 4- 5 degrees. The camera can show this heat difference underneath. 

There is a lot of benefit to using this camera. 

  • They have a different temperature than the environment temperature.
  • No damage was caused to any surface.
  • Quick and efficient leak detection.
  • Professional identification of hot and cold temperatures within the walls, or underneath the floor.

The camera is endoscopic, extendable, and flexible. It gives a visual inspection to our expert, for the areas which are hard or impossible to reach.
