Invasive moisture testing looks below the surface.

Our invasive moisture testing gives you valuable insight into what’s causing any leaks and enables an accurate scope of works to be drawn up.


Don’t be left wondering what’s causing an abnormal moisture reading.

So you’ve got a high moisture reading – now what?

Don’t turn your back on a high moisture reading, cracking, cladding damage or discolouration – get to the bottom of the issue with our thorough invasive moisture testing service.

Invasive moisture testing (also known as intrusive inspection) involves physically opening up areas of, or around, a high moisture reading. We use specialist equipment such as driven probe hammers and endoscope cameras to gain a detailed picture of what’s going on within a building.

Invasive testing can involve:

  • Accurate moisture readings taken at different depths to ascertain the extent and spread of the issue
  • Taking core samples of internal framing to ascertain the condition of affected timbers
  • Determining the cause and extent of water ingress or internal leakage
  • Taking photographs within the building structure, with the use of endoscope cameras, to determine the condition of hidden building elements
  • Production of a scope of works to road map needed repairs and remedial works
  • Recommendations for improvements and direction to contractors

Once the invasive moisture testing process has been completed, we provide you with an accurate scope of works that outlines needed repairs so you (and your tradesmen) can plan and understand the remedial work required.
