How to Keep Your Home Mould-Free After Wet Weather (Without the Stress!)

Let’s talk about an unwelcomed guest that loves to show up after a stretch of wet weather (like the recent ex-cyclone Alfred here in Queensland!)—mould. That musty smell, those sneaky little spots creeping across your walls, and that feeling of frustration when you realize your cozy space has been taken over? Ugh, no thanks!

Mould adores damp, humid environments, making rainy weeks its perfect excuse to settle in. But don’t worry! With a few simple steps, you can stop it before it even starts and keep your home fresh, dry, and healthy.

Why Does Mould Show Up After Wet Weather?

Mould spores are always floating around in the air, but they need moisture to latch onto and grow. After days of wet weather, excess moisture in your home can create the ideal conditions for mould to flourish. Here’s why:

• Hidden leaks and dampness – Water can sneak into walls, floors, and furniture, leading to long-lasting moisture issues.
• Humidity overload – Post-rain humidity levels can soar, making it hard for things to dry out properly.
• Poor ventilation – If windows and doors are shut tight to keep out the rain, air circulation slows, and moisture gets trapped inside.
• Soaked materials – Waterlogged carpets, drywall, or insulation take forever to dry, giving mould the perfect breeding ground.

Easy Steps to Keep Mould Away

The good news? You don’t need to stress—just a few proactive moves can keep your home mould-free.

1. Dry It Out—Fast!

Mould can start growing within 24-48 hours, so time is key! As soon as the rain stops, open up windows and doors to let fresh air in. Turn on fans, use dehumidifiers, and if any fabrics or furniture got damp, dry them out ASAP.

2. Check for Sneaky Leaks

Even small leaks can lead to major mould issues. Inspect your roof, walls, and plumbing for any drips or water damage. Fix leaks quickly and use waterproof sealants in moisture-prone areas.

3. Wipe It Down & Disinfect

Any damp surfaces? Give them a thorough wipe-down with a mix of white vinegar and water, hydrogen peroxide, or a gentle bleach solution. These help kill off any lurking mould spores before they spread.

4. Boost Airflow & Ventilation

Good air circulation is your best friend when it comes to moisture control. Turn on exhaust fans in the kitchen, bathroom, and laundry room. If you can, leave windows slightly open on dry days to keep fresh air moving through your home.

5. Toss Water-Damaged Materials

Unfortunately, some materials just won’t recover from too much moisture. If carpets, insulation, or drywall have been soaked for too long, it’s best to remove and replace them before mould becomes a long-term issue.

6. Keep an Eye on Humidity

Using a simple hygrometer (a handy little gadget that measures humidity), aim to keep indoor levels below 60%. If it’s creeping up, use a dehumidifier or air conditioner to bring things back to balance.

What If Mould Has Already Started Growing?

If you’ve spotted mould, don’t panic—but don’t ignore it either. Small patches can be scrubbed away with mould-killing cleaners, but if it keeps coming back or covers a large area, professional help might be the way to go.

Mould exposure can trigger allergies, respiratory issues, and even fatigue, so keeping your home mould-free isn’t just about cleanliness—it’s about your health and well-being too.

Keep Your Space Fresh & Healthy

Dealing with mould might not be the most glamorous part of home care, but a little prevention goes a long way. After wet weather, stay on top of moisture levels, keep things dry, and act fast if you spot trouble. Your home will stay fresh, cosy, and safe for you and your family.
