Could your London property be suffering from penetrating damp?

Penetrating Damp has another name-- 'rain penetration,' which refers to moisture seeping inside the structure from outside sources. The following are the usual suspects of moisture penetration:

  • Guttering and downspouts that are broken or missing
  • Rendering or masonry cracks
  • Brickwork and pointing damage
  • Poor-quality mortar or porous bricks
  • Roof cracks/damage or missing roof tiles
  • Drainage systems that are faulty or clogged
  • Coatings/paint for non-breathable outer walls
  • Window sills that are broken or missing

Damp can impact both old and new structures, and if left unchecked, it can cause irreversible property damage. The problem is frequently worse during extended periods of rain.
