What is Penetrating Dampness and how does it occur? 

Penetrating Dampness is the result of moisture, usually in the form of water, penetrating the walls, floors and ceilings, which can cause serious damage to the property. It occurs when water penetrates cracks and voids in the building’s structure, or when water is driven into the building by wind, rain or condensation.

Penetrating walls, floors and ceilings

Penetrating dampness occurs when water enters the building’s structure from the outside, or from an internal source. It can be caused by a number of different factors including leaking or broken pipes, poorly maintained roofs, poor drainage and inadequate weatherproofing.

A myriad of problems

When water penetrates a building it can cause a number of different problems that can be damaging to both your property’s structure and your health. It can cause damage to walls, floors, ceilings, furniture and structural timber whilst promoting mould growth and condensation.

Survey and solutions

If you suspect that you have a problem with penetrating dampness in your building, it is best to contact a specialist to undertake a survey and recommend solutions. The sooner you identify and address the issue, the better, as problems with dampness can quickly cause extensive damage if left untreated.

How do I identify Penetrating Dampness


Penetrating Dampness often causes very clear areas of discolouration of your walls, floors or ceilings. In some cases, this will have a “blotchy” appearance.


Similar to other damp problems you may notice a general musty smell in the air. This can indicate that the moisture levels are high and that the dampness is a problem.


Identifying by touch is as simple as placing your hand on the wall, floor or ceiling and feeling for dampness. Other indicators can be the flaking or peeling of paint when you brush your hand over the area.

What does Penetrating Dampness look like?

The most common signs of penetrating dampness are staining, discolouration, or bubbling of paint or wallpaper, as well as mould or mildew growth. Musty odours, a feeling of dampness in the air, and the presence of insects such as silverfish or woodlice can all be signs of dampness
