Penetrating Damp: Causes, Signs and Treatment

If you’re a homeowner, chances are that you’ve been subjected to penetrating damp on interior walls at some stage in your life. If not, consider yourself lucky!

Penetrating damp also known as lateral damp is the horizontal intrusion of moisture through walls. It can happen as a result of structural issues such as damaged roofing or gutters as well as cracks in external walls. This type of damp can happen at any level thus affect walls, roofs, and ceilings. Below are some of the common causes of penetrating damp according to the professionals.

Leaking Walls

Wet walls are typically the first sign of penetrating damp. Damp patches, discolouration, mould growth, flaking plaster are all signs of penetrating damp.

Openings

Damage to doors and window frames that allow for air gaps, can lead to penetrating damp. Ensure that you fix damage promptly whenever it occurs to secure an airtight property.

Burst Pipes and Leaky Gutters

Leaks from gutters and downpipes can cause penetrating damp so make sure you identify cracks and fix them to solve the problem.

Permeable Bricks

Bricks that are old can become porous and allow water to enter your home. If you suspect that this is the case, you might need to have them replaced. Another option to consider is to use damp-proof exterior paint to coat your property exterior. This will seal your walls while allowing them to breathe. Before you commence with this treatment option, we advise you to consult with a professional to determine what would work best in your unique situation.
