Penetrating damp internal wall

Many people will be unaware that their property has a problem with penetrating damp until the signs become visible on their internal walls.

Internal walls display the signs of penetrating damp due to water infiltrating the building through porous walls or via a defect in the building. If you notice the appearance of damp patches or crumbly plaster on your walls but you can not identify the source of water ingress then it is recommended that you seek professional assistance to identify and fix the problem before it deteriorates any further.

Do I have penetrating damp on my internal walls?

Amongst the various signs of penetrating damp affecting internal walls, the most common is the appearance of blotchy patches of damp on the surface of the internal wall that may get darker and larger in the event of heavy rainfall. In addition to this, the other signs to look out for are:

  • Paint and plaster deterioration
  • Water staining
  • The appearance of black mould
  • In extreme cases you may find water dripping and leaking through the wall

Evidence of damp on internal walls does not necessarily point to penetrating damp straight away. There are other types of damp you might want to consider. What we would suggest however, is that if there is no obvious source of the water ingress into the property leading to penetrating damp and you are struggling to determine why you are suffering damp on your internal walls,  then it is recommended that you should contact a damp specialist such as ourselves to organise a damp survey.

How to treat penetrating damp on interior walls

The initial step to combating penetrating damp on internal walls or anywhere else in the property is to firstly identify and repair the defect that is allowing water ingress into the property.
