Spotting Mould Before It Throws a Party

Trust your nose and your eyes.

• Look for black, green, or white specks on walls and ceilings.
• Check skirting boards behind furniture and inside cupboards.
• Watch for paint that bubbles or peels like a bad sunburn.
• Sniff for that musty gym bag smell after rain.
• Keep an eye on bathrooms, laundries, and basements.

First 48 Hours After a Soak

Act fast and keep it simple.

• Stay safe and cut power to wet areas if there is any risk.
• Wear gloves, eye protection, and a good mask.
• Open windows and doors for fresh air.
• Set up fans to push air out of the room.
• Run a dehumidifier if you have one.
• Remove standing water with mops and a wet vac.
• Blot carpets and rugs and get them drying in fresh air.
• Lift furniture on blocks so air can move under it.
• Bag and bin soggy items that cannot be cleaned.
• Dry everything within 24 to 48 hours if you can.

CASE STUDY: Mould Inspection and Moisture Assessment

On 5 March 2026, Elite Restoration conducted a professional mould inspection following concerns of microbial growth caused by ongoing water ingress from leaking bathroom showers.

The inspection identified failure in shower waterproofing as the likely cause, leading to moisture migration into adjacent wall cavities and surrounding areas.

While general living spaces showed no visible mould contamination, elevated moisture levels were detected within bathroom areas.

Further investigation confirmed localised mould growth within the Bathroom 1 shower wall cavity, along with elevated airborne fungal levels across the bathroom and nearby areas.

Moisture intrusion was also identified in the ensuite walk-in robe, indicating concealed water damage linked to the leaking shower system.

Laboratory testing supported these findings, detecting increased fungal spore counts consistent with moisture-affected environments.

Elite Restoration recommended immediate repair of the leaking showers to prevent further water damage and mould growth.

Additional actions include opening wall cavities to assess hidden damage, replacing affected materials, and improving ventilation systems to control humidity.

Professional duct cleaning was also advised to remove mould spores from the HVAC system and prevent re-contamination.

How to Clean Small Mould Patches

Keep it small and keep it safe.

• Send young kids and pets out of the room.
• Wear gloves, goggles, and a mask.
• Mix warm water with a squirt of dish detergent.
• Scrub the mould on hard surfaces with a sponge.
• Rinse with clean water and dry the area well.
• If stains remain on hard surfaces, you can use bleach as directed on the label.
• Never mix bleach with any other cleaner.
• Open windows while you clean and for a while after.
• Throw out porous items like soggy ceiling tiles and mouldy cushions if they stay musty.
• Vacuum with a HEPA filter once the area is dry.

When to Bring in the Pros

Call for help when the mould looks like it is hosting a music fest.

• The area is bigger than a door.
• Water came from stormwater or sewage.
• The mould keeps coming back like a boomerang.
• It is in the air conditioning or inside the walls.
• Someone in the home has asthma, allergies, or low immunity.

Keep Mould Away After the Clean

Think dry air and good flow.

• Keep indoor humidity near 50 percent or lower.
• Use exhaust fans in the bathroom and laundry.
• Open windows on dry days like it is a fresh ocean breeze.
• Fix leaks in roofs, pipes, and showers fast.
• Clean gutters so water does not spill into walls.
• Leave space between furniture and walls.
• Dry wet spots within a day.
• Run a dehumidifier during wet months.
• Service your air con and clean filters.

Quick Checklist for Owners and Renters

FAQs About Mould Growth After Water Damage

Is the smell a worry?

A musty smell means moisture is still around, and that invites mould.

Keep drying until the smell fades.

What kills mould best?

Detergent and water on hard surfaces work for many small spots.

Use bleach only on hard surfaces and follow the label.

Never mix cleaners.

How long does drying take?

Small areas can dry in a day with good airflow.

Big wet rooms can need a few days with fans and a dehumidifier.

Can I keep the wet carpet?

You can if it dries fast and smells fresh.

If it stays musty or stained, it may need to go.

Will paint stop mould?

Paint is not a raincoat for mould.

Fix the moisture first, then paint.
