Understanding Mould: What Is It and Why Does It Grow?

Mould is a type of fungus that naturally exists in the environment and plays a vital role in decomposing organic matter. However, it becomes problematic when it grows indoors. Mould reproduces through tiny spores that float in the air, settling and thriving in damp, dark, and warm environments.

Common places mould can grow include:

• Bathrooms due to steamy showers or leaking pipes.
• Basements where humidity often builds up.
• Kitchens around sinks, refrigerators, and other appliances.
• Windowsills with condensation.

Why does it matter? Mould can cause structural damage to your home, discolor walls, and even release unpleasant odors. Health-wise, exposure to mould can trigger allergic reactions, respiratory problems, or asthma attacks, especially for sensitive individuals.

Prevention: Tips to Keep Mould Away

Prevention is always better than dealing with mould afterward. Here are some detailed tips:

1. Control Humidity Levels:

• Invest in a hygrometer to monitor indoor humidity. Ideally, levels should stay between 30%-50%.
• Use dehumidifiers, especially in areas like basements.
• Run air conditioners during hot, humid days to prevent moisture buildup.

1. Ensure Proper Ventilation:

• Install exhaust fans in bathrooms and kitchens to remove excess moisture.
• Open windows regularly to increase airflow.
• If your home lacks ventilation, consider installing vents or louvers to encourage air circulation.

1. Fix Leaks Promptly:

• Check faucets, pipes, roofs, and walls for leaks or drips. Even a tiny leak can lead to water accumulation over time.
• Seal window frames and gaps around doors that could let rain in.

1. Regular Cleaning:

• Clean areas that experience frequent moisture, such as shower stalls and kitchen counters.
• Use cleaning agents like white vinegar, hydrogen peroxide, or baking soda, which inhibit mould growth naturally.

1. Keep Indoor Plants Mould-Free:

• Water plants moderately, and avoid leaving excess water sitting in trays.
• Wipe leaves occasionally to remove accumulated moisture and dust.

Spotting Mould: Early Signs to Watch For

Detecting mould early can save you from larger problems later. Here’s what to look for:

• Discoloration: Mould appears as black, green, brown, or white spots and patches. Sometimes, it looks fuzzy.
• Musty Smell: A persistent earthy odor that doesn’t go away after cleaning may indicate hidden mould.
• Water Damage: Look for signs like peeling paint, bubbling drywall, or stains on ceilings—these often indicate trapped moisture, which can encourage mould growth.
• Condensation: If condensation frequently forms on walls, windows, or pipes, it could be a red flag for mould-prone conditions.

Safe Mould Removal: DIY Methods

If mould growth is minor, you can tackle it yourself with these methods:

1. Small Areas:

• Mix one part bleach with ten parts water and apply it to the affected area. Let it sit for 15 minutes before scrubbing.
• For natural alternatives, spray white vinegar or hydrogen peroxide directly onto mould and let it air-dry.

1. Equipment:

• Always wear safety gear: gloves, goggles, and a mask (preferably N95) to prevent exposure to mould spores.
• Use a HEPA vacuum cleaner to capture mould spores from surfaces after scrubbing.

1. Techniques to Avoid:

• Don’t use dry brushing or scrubbing methods, as these can release mould spores into the air and make the problem worse.

When to Call Professionals

Some situations are too dangerous or extensive for DIY efforts. Knowing when to involve experts is crucial:

• Large Mould Infestations: If mould covers more than 10 square feet, it’s best to hire professionals.
• Contaminated Water: Mould caused by sewage backups or flooding should be handled by specialists trained in biohazard cleanup.
• Persistent Mould Issues: If mould keeps returning after repeated cleaning, there may be hidden leaks, poor ventilation, or other problems requiring professional intervention.

Long-Term Mould Management

Once you’ve removed mould, it’s time to take steps to ensure it doesn’t return. Here’s how:

• Use Mould-Resistant Paint: Specialty paints and primers can be applied to walls and ceilings prone to moisture.
• Install Vapor Barriers: Especially useful in basements, vapor barriers prevent ground moisture from seeping in.
• Inspect and Maintain Appliances: Make sure air conditioners, humidifiers, and other appliances aren’t leaking or contributing to humidity.
• Monitor Flood-Prone Areas: If you live in a region prone to flooding, keep sandbags handy and ensure your home’s foundation is sealed properly.

When to Call a Mould Specialist

While Ottawa Handyman Inc. can assist with general repairs and small mould removal tasks, large infestations or mould caused by contaminated water (like sewage backups) should be handled by certified mould remediation professionals.
