Why Is Black Mould Growing? Key Causes and Conditions

Knowing the root cause of the black mould in your home helps you to diagnose and treat it properly.

Poor ventilation in areas such as bathrooms and kitchens also results in moisture accumulation, offering an ideal breeding ground for mould.

Leaks from roofs, windows, or pipes present additional risks by allowing water intrusion that fuels mould growth.

It’s important to inspect your home from time to time, paying special attention to areas like furniture or under sinks, where black mould can really begin to thrive.

How to check for black mould in your home:

• Walls and ceilings near bathrooms and kitchens.
• Corners behind furniture, especially in humid environments.
• Under sinks and around plumbing fixtures.
• Around windows and doors where condensation occurs.
