Identifying Rising Damp in Umhlanga

Rising damp on walls refers to the slow upward movement of water in the lower sections of walls. You can observe this by placing a brick in a shallow tray of water and watching how the water is absorbed and transported above the water line.

Rising damp can be identified by tide marks on the lower section of affected walls, caused by soluble salts (particularly nitrates and chlorides) contained in groundwater. If water enters your property due to prolonged rainfall, damp patches may appear on inner walls, leading to condensation in cold, damp areas. Water droplets may be visible if the damp problem is severe, but there will be no salts rising from the ground.

Symptoms of Rising Damp

Look for these symptoms to identify rising damp:

• Damp patches on walls, especially during windy and rainy weather, which may disappear when the weather clears.
• Deterioration and blistering of plaster and paint.
• Rotting skirting boards.
• Mold growth and a moldy smell.

Identifying Penetrating Damp in Umhlanga

Watermarks on walls, windows, and ceilings indicate a penetrating damp problem. When SMDA Maintenance checks these areas, we will invariably show high moisture readings.

Symptoms of Penetrating Damp

These signs indicate penetrating damp:

• Damaged plaster, as moisture compromises its quality.
• Mold growth on walls, which can also be a symptom of condensation.
• Wet rot affecting timber, leading to wood rotting and serious damage to the building’s infrastructure.
• Discoloration or dampness in the property’s interior décor.

Identifying Condensation Damp in Umhlanga

Condensation occurs when warm, moisture-laden air contacts a cold surface, such as a wall or window. Unlike rising and penetrating damp, condensation is more common during colder months. Condensation tends to leave patches of black mold on walls rather than stain marks, and it usually occurs in still air areas like corners of rooms or behind furniture.

Symptoms of Condensation Damp

Watch for these symptoms of condensation damp:

• Black mold, which can appear on any walls of the property.
• Water collection on windows.
• Deterioration of plaster if the problem isn’t addressed quickly, with walls appearing wet.
