How to Get Mould Out of Carpet After a Flood or Leak

Mould damage in your carpet is more than just unsightly—it’s a health hazard. Whether caused by a flood, a leaky pipe or condensation, mould spreads quickly and thrives in damp fibres. If you’ve recently experienced water damage, knowing how to get mould out of carpet is crucial to protect your home and your health.

At Disaster Care Capital, we’ve helped countless homeowners recover from fire and flood damage. Carpet mould is one of the most common—and preventable—issues we see during home restoration.

Why Does Mould Grow in Carpets

Mould spores exist naturally in the air. When they land on damp material, they begin to grow. Carpet and underlay hold moisture easily, especially after flooding, spills, or poor ventilation. If left untreated, mould can lead to:

• Musty odours
• Discolouration
• Allergic reactions
• Structural damage to floors

How to Get Mould Out of Carpet Yourself

If the affected area is small and caught early, you can try these DIY mould removal methods using common household items:

1. White Vinegar

White vinegar kills 80% of mould species. Mix equal parts vinegar and water, spray onto the affected area, scrub gently, and leave to dry.

2. Baking Soda

Sprinkle baking soda over the mouldy area. Let it sit for a few hours, scrub with a brush, then vacuum thoroughly.

3. Clove Oil

Mix ¼ teaspoon of clove oil with 1 litre of water. Apply lightly with a cloth, leave to sit, then vacuum or dab dry.

Always wear gloves, a mask, and eye protection. Mould spores can be hazardous to breathe in—especially for asthma sufferers.

For larger infestations, or if you’re unsure about black mould, it’s safer to call a professional.

When to Call the Professionals

You should call professional mould removal services if:

• Mould keeps returning
• The area is larger than one square metre
• There’s a persistent mouldy smell
  
• You experience respiratory symptoms during cleaning

At Disaster Care Capital, our team uses commercial-grade dehumidifiers and HEPA filtration to safely remove carpet mould and prevent regrowth.

We also inspect for hidden moisture using thermal imaging.

• Fix leaks quickly and dry wet carpets within 24 hours
• Improve ventilation—especially in basements and bathrooms
• Avoid carpeting in high-risk areas like kitchens or wet rooms
