Penetrating Damp

Penetrating damp happens when water gets into a property from outside. There are many different problems that can cause this. For example, your guttering or mortar may be damaged, or you may have loose roof tiles. Internal leaks, plumbing problems and gaps in windows or doors can also lead to penetrating damp.

Common signs of penetrating damp include:

• damp patches on your walls or ceilings
• wet or crumbling plaster (this can also occur on unlined chimney breasts)
• signs of spores or black mould that are isolated to one area
• drips and puddles.
