How to prevent penetrating damp

The traditional method of treating damp is chemical injection which is usually done by creating a barrier between the damp and the house, however, it doesn’t address the root cause and is not a permanent solution.

Penetrating damp occurs when water from outside your home leaks inside the property. The cause could be small cracks in a wall, leaky pipes or blocked guttering with flashing around a chimney stack, damaged pointing or poorly fitted windows other sources. Continually being on the lookout for any signs will help you identify issues quickly:

  • Test moisture levels with an electronic moisture meter
  • Check downpipes are clear and household appliances are not leaking regularly
  • Installation is carried out from the outside of your home only, not inside
  • More cost effective than traditional damp treatments that require replastering and redecorating
  • Look for water coming into the loft from the roof
  • Make sure there are no cracks in your rendering
  • Always keep your damp-proof courses clear
