Penetrating Damp Symptoms

Before any form of dampness in walls can be treated, the source of the damp problem must be correctly identified. In order to find out which type of dampness is affecting masonry, a full examination of the property should be undertaken.

Penetrating Damp Symptoms on External Walls

External walls

Signs of penetrating damp can often be seen on the outside of houses. Damaged brickwork, moss and algae growth, as well as localised damp patches are common symptoms of penetrating damp.

Damage to Brickwork

Damaged brickwork will worsen if left untreated

One of the symptoms of penetrating damp is damaged brickwork on external walls. This is mostly caused by frost damage. When water freezes it expands. Moisture, which penetrated brickwork, expands in freezing weather conditions causing spalling and cracks in the structure of the wall.

Moss Growth on Outer Walls

Moss growing on brickwork

Damp walls are a perfect substrate for moss and algae growth. These organisms are attracted to damp substrates and can spread widely along walls. Damp penetrating masonry ensures a habitable space for moss, resulting in an unaesthetic appearance.

Isolated Localised Dampness

Isolated localised dampness

Common symptoms of penetrating damp are localised damp patches on walls. Watermarks appear as a result of damp penetrating brickwork. These damp patches can grow in size when moisture continues to enter bricks.

Internal Penetrating Damp Symptoms

Internal walls

Symptoms of penetrating damp are not only visible on external walls. Common signs of penetrating damp on the inside of walls are damaged plasterwork, rotten timber and mould growth.

Damage to Plasterwork

Damaged plaster

Penetrating damp can cause the deterioration of paints and plaster, blistering, and the appearance of stains and salts on the surface of walls.

Wet Rot Affecting Wooden Fixtures

Wet rot

Damp brickwork can seriously affect wooden fixtures directly connected with it. Water can seep through bricks and saturate timber, causing it to rot and decay.

Mould on Walls

Mould on Walls

Mould growth on walls is commonly associated with condensation, but can also be a symptom of penetrating damp. The damp wall surface is an ideal substrate for mould growth.
