Common Causes of Mould on Skirting Boards

Skirting boards near floors and skirting joints trap moisture, especially in humid or poorly ventilated areas. Leaky pipes, condensation from warm air, and spills create ideal conditions for mould spores to colonize. Over time, organic materials in the wood surface feed the growth, turning minor dampness into visible black or green patches.

Effective Prevention and Removal Strategies

To keep skirting boards mould-free, ensure proper ventilation and reduce humidity with dehumidifiers or exhaust fans. Clean regularly with mild detergent and water, avoiding harsh chemicals that damage wood. Seal joints and apply mould-resistant paints or treatments. For severe infestations, professional remediation is recommended to eliminate spores and restore safety.
