How Does Penetrating Damp Occur?

Penetrating damp can occur in a number of ways, though most commonly it is due to an excessive amount of water coming into contact with the building’s structure.

If your building has been built with a solid wall, (generally those built prior to 1920’s had no cavity), then you are more likely to experience penetrating damp. This is because any defects in the outer wall will easily allow for the transfer of moisture through to the internal wall. In contrast, a cavity wall property means that any moisture from defects on the outside will not come into contact with the internal wall.

If you think you might be at risk of penetrating damp on internal or external walls due to suspected defects within your home or building, we can arrange a property survey to determine whether you require penetrating damp treatment.

Some of the main causes of penetrating damp include:

• Overflowing gutters
• Blocked or leaking pipes
• Missing roof tiles
• Old porous brickwork
• Damaged brickwork
• Damage caused by subsidence
• Damaged seals around doors and windows
