Mould buildup reasons are numerous and varied. This stealthy intruder frequently finds its way into homes, undermining aesthetics, structural strength, and even health. But why exactly does mould decide to breach our living spaces? Let’s delve deeper to understand the primary factors

Moisture and Humidity: A Mould Magnet

  • Every home has its damp corners. Whether it’s a result of external weather conditions, indoor activities like cooking and showering, or unnoticed leaks, mould relishes in these moist environments. By maintaining indoor humidity below 60% and fixing leaks promptly, you can starve mould of its favourite snack.

Ventilation Woes: Trapped Moisture’s Playground

  • It’s crucial to ensure every room in your home breathes. Bathrooms, kitchens, and basements are especially susceptible. The moisture generated in these spaces can become trapped due to inadequate ventilation, setting the perfect stage for mould to grow. Simple habits like turning on exhaust fans and regularly opening windows can help.

Dark Corners: Mould’s Secret Hideout

  • One of the often-overlooked mould buildup reasons is the presence of dark and undisturbed areas in our homes. Mould thrives in the shadows. These dimly lit corners, hidden nooks, and infrequently accessed storage areas provide the perfect sanctuary for mould spores to settle and multiply. Combine this darkness with even a slight amount of moisture, and you’ve got an environment where mould can flourish unhindered.

Household Leaks: Uninvited Guests

  • A small drip might seem harmless, but over time, it creates a moist environment where mould can flourish. Regular maintenance checks for plumbing, roofing, and other structures can save you from bigger troubles down the line.

Material Choices: Building a Mould-Resistant Home

  • Materials like wood and wallpaper can act as food for mould when they get damp. Opting for mould-resistant products when building or renovating can make a significant difference.


Mould can be a daunting adversary, but with awareness and proactive measures, you can keep your home mould-free. Remember, prevention is always better than the cure.
