What Is Green Mould? Identification, Prevention, and Removal Tips

What Is Green Mould?

Green mould is a common fungal species that appears greenish. The most common types of green mould include:

• Cladosporium: Often found on wood, fabrics, and cooling systems.
• Aspergillus: Food, walls, and insulation systems are the common targets.
• Penicillium moulds: Found on water-damaged materials and spread quickly.

Where Does Green Mould Grow?

Damp and humid environments are hotbeds where green mould thrives. Places around windows, or bathrooms, kitchens, basements, and attics often attract them. Basically, if there’s condensation or water leaks, there could be green mould. Poor ventilation and organic materials, like wood or drywall, often fuel mould growth. If conditions are right, mould spores can start colonising within 24 to 48 hours.

How to Identify Green Mould

Let’s check out some visual signs and other clues indicating that this uninvited guest has entered your property.

Visual Signs of Green Mould

Green mould usually appears in bright green or dark olive patches. But despite having the green hue, it’s a complete red flag. Depending on moisture levels, this pesky fungus can have powdery or slimy textures.

Musty Odours and Other Clues

To spot green mould growth, your nose can act faster than your eyes. Green mould has a musty, earthy smell. Does your room consistently smell damp or unpleasant despite cleaning? If yes, this green fungus is probably taking over. Check behind walls, under carpets, or inside your HVAC ducts. These are the most common spots these unwanted guests hide in.

Health Symptoms Associated with Green Mould Exposure

Green mould exposure can trigger a variety of symptoms. These include:

• Allergic reactions: Sneezing, coughing, nasal congestion, and eye irritation.
• Asthma flare-ups: Mould spores can aggravate breathing conditions.
• Skin rashes: Direct contact may cause itchy or inflamed skin.

Prevention Tips for Green Mould

Follow these best practices to keep mould from infiltrating your property so you don’t end up spending time and money on it later.

Moisture Control and Ventilation

This is the most rudimentary mould prevention method. Keeping indoor humidity under 50% is one of those first steps you can take towards mould growth prevention. For bathrooms, kitchens and other moisture-prone areas, use exhaust fans and open windows to dehumidify the area. Or you can just use dehumidifiers for highly-humid areas like basements. Often check for leaks or condensation on windows as well. If you spot it, stopping it right away can prevent future mould growth.

Routine Cleaning and Maintenance

Cleanliness goes a long way in preventing mould growth, especially in high-risk spots like shower tiles and under sinks. Natural solutions like baking soda or commercial mould cleaner can also work on stubborn stains.

Home Inspection and Repairs

Prevention saves you stress and the dollars you’ll end up spending on those surface damage repairs if you don’t get rid of it early. Inspect your home (at least once a year) for signs of water damage, leaks, or poor drainage. Your HVAC systems and gutters can also shelter green mould. Clogged gutters or dirty vents also create a sweet spot for green mould growth. In the end, water intrusion is the biggest culprit behind mould infestation. Stop it, and you won’t have to worry about this pesky issue.

How to Remove Green Mould Safely

Depending on the intensity, you can take on the mould growth on your own or with a professional’s help.

DIY Mould Removal Methods

If that green patch is frail and small, a DIY cleaning session can save you time and dollars. Just make sure you wear protective gear such as gloves, a mask, and goggles. You don’t want to risk your health while cleaning it. You can use DIY cleaners like:

• Vinegar: Spray onto the mould, let it sit for 30 minutes to an hour, and then scrub.
• Baking soda: Mix with water to prepare a gentle, anti-mould cleaning solution.
• Hydrogen peroxide: This is useful on hard surfaces and effective against most mould types.
