Property damp has many causes, water leaks, condensation but not always or even often rising damp. But it always has negative effects on your built environment including rot and infestation of wood boring creatures.

Wood Rot

Whether “dry rot” or wet rot all wood rots are caused by damp conditions. We need to find and control the water egress then remove the rot.


Evidence of Woodworm or other wood boring beetle infestation can be devastating to the structure of a building, or the marks and holes may be historic. For your peace of mind we need to diagnose quickly.

Japanese Knotweed

Evidence or suspected presence of Japanese Knotweed can halt a property sale or mortgage, we can survey the site quickly and accurately.


Condensation quickly leads to poor living conditions including black mold, wood rot or even infestation. We look at sources of moisture, ventilation, life style and building materials.
