Yes — mould can permanently damage an oil painting if it is left untreated for too long. Mould growth affects more than just the appearance of a painting; it can weaken the paint layer, stain surfaces, compromise canvas fibres, and create long-term structural issues. In humid coastal climates like Durban, mould damage is one of the more common reasons people seek professional restoration.
The good news is that early intervention can often prevent severe deterioration. If you suspect mould growth on your artwork, it is best to contact Barnard Oil Painting Restoration for professional advice:

Mould thrives in warm, humid environments with poor airflow. This makes oil paintings particularly vulnerable when they are stored incorrectly or exposed to moisture.
Common causes include:
Durban’s climate creates ideal conditions for mould growth, making preventative care especially important.
Mould can penetrate microscopic openings in the paint surface. Over time, this may cause discolouration, staining, or lifting of the paint layer.
If mould spreads into the canvas or support structure, it can weaken fibres and create structural instability.
Some mould species leave permanent staining behind if not treated quickly.
Left untreated, mould continues spreading. What begins as a small patch can eventually affect large areas of the artwork.
This is why mould damage should always be treated as early as possible.
People often mistake mould for dirt or surface staining. Knowing what to look for can help prevent permanent damage.
Signs include:
