Mold is a common problem in humid and dusty climates, and one of the most frustrating issues homeowners face is black mold on the outside of the house. It not only looks unpleasant but also weakens walls and poses health risks if it spreads indoors. Whether you’re dealing with mouldy walls outside or inside your bathroom, knowing the right techniques for removing mould from walls is essential for protecting both your property and your health.
🌬️ Why Does Black Mold Appear on Walls?
Mold thrives in damp, shaded, and poorly ventilated areas. On the exterior of houses, it usually grows due to:
- Constant exposure to rain and humidity.
- Shaded walls with little sunlight.
- Poor drainage or water leaks.
- Porous wall materials that absorb moisture.
Indoors, mouldy walls are often found in bathrooms, kitchens, and areas near air conditioning ducts.
🚫 Risks of Leaving Mold Untreated
Ignoring black mold on outside of house or on indoor walls can lead to:
- Permanent staining and structural damage.
- Spread of spores indoors, affecting indoor air quality.
- Health issues such as allergies, asthma, and skin irritation.
That’s why getting rid of mould on walls should never be delayed.
