Why is Your Home Growing Mould?

You might have spotted it lurking in the bathroom, flaunting itself on the walls, or, heaven forbid, snuggling into your wardrobe. But why, oh why, is mould turning your home into something more akin to a mushroom frame than a cosy living space? Here are a few possibilities:

1. The Leaky Roof Problem

Let’s start from the top, shall we? Your roof. If it’s in disrepair, it might as well be sending out engraved invitations to every spore in the vicinity. Cracked tiles or worn-out roofing materials can let water sneak into your loft, creating a plush, damp environment where mould thrives like gossip in a tea shop. Regularly check your roof for signs of damage, and call a roof repair company to patch up any issues quicker than you can say "drip."

2. Condensation: The Mould’s Cocktail Party

Ever noticed how mould is a social creature, loving areas like your kitchen and bathroom? That’s because these spots frequently host the hottest parties, a.k.a. condensation. Cooking, showering, or even breathing—yes, how dare you—creates moisture. If your home isn’t well-ventilated, that moisture will settle down and get comfortable, and before you know it, mould starts to crash the party. Invest in a decent extractor fan, and let that steamy air out!

3. That Shady Cold Wall

Mould adores a good, cold wall, particularly the ones that never see the sun. These chilly, damp surfaces are prime real estate for mould spores. It’s like mould’s version of a chilly beach holiday, minus the piña coladas. Insulating your walls or even rearranging your furniture so that air can circulate freely might just evict those freeloading fungi.

4. Floods and Spills: Mould’s Favourite Disaster Movie

Had a little flood recently? Or maybe just a spill you didn’t dry up as quickly as you should have? Mould loves a good water feature inside your house. Whether it’s from leaking pipes, overflowing baths, or that time you tried to water your indoor plants with a hosepipe, any standing water that’s left to its own devices can and will encourage mould growth. Dry out any wet areas promptly—mould moves faster than a bargain hunter at a sale.

5. Heating or Lack Thereof

Turning the heating on and off or letting your home get too cold can cause condensation when it suddenly warms up again. It’s like when you leave a cold drink out on a warm day, and suddenly it’s sweating like it ran a marathon. Keeping a consistent temperature in your home can help prevent this kind of moisture build-up.



6. Your Green Thumb

Lastly, let’s talk houseplants. While they’re great for air quality, overwatering them can increase humidity levels in your home. Mould might just think it’s landed in a tropical paradise. Make sure your indoor jungle is well-maintained and not turning your home into a greenhouse.

Now you know some of the most common causes of mould, you can start eliminating each and every threat to your house from the problematic invader, and get your home back, to its best!
