Mould is a common household issue that can have serious health and structural consequences if left unchecked. These tiny microorganisms thrive in moist environments, and their presence can lead to a host of problems ranging from allergic reactions to respiratory issues.

In this comprehensive guide, we'll explore the dangers of mould, how it enters our homes, and most importantly, practical tips to prevent it from growing in your living spaces.

What is Mould?

Mould is a type of fungus that grows in damp and humid conditions. It is found virtually everywhere and can grow on almost any surface if the conditions are right. Indoors, mould often appears on damp surfaces like bathroom walls, around windows, and in basements. Mould can take on various appearances, such as furry growth, black stains, or specks of different colors like black, white, orange, green, or brown. The growth of mould is not just a cosmetic issue; it can significantly impact the quality of air in your home and the health of its occupants.

How Does Mould Get Into Our Homes?

Mould spores are microscopic and can easily enter your home through open doors, windows, and vents. They can also be carried indoors on clothing, shoes, and pets. Once inside, mould spores can settle on surfaces and begin to grow if the conditions are favorable.

The more people living in a home, the higher the likelihood of mould growth due to increased moisture in the air. Activities like cooking, showering, and even breathing release moisture, creating an ideal environment for mould to thrive. Additionally, unattended water damage, lack of ventilation, storing wet items like firewood, overwatering plants can contribute to mould problems.

The Health Risks of Mould Exposure

Mould can be harmful to your health, especially for those who are sensitive or allergic to mould spores. When mould grows, it releases spores into the air, which can cause a range of health issues if inhaled. Some common health problems associated with mould exposure include:

Chronic Allergies: Mould spores can trigger allergic reactions ranging from mild to severe, including symptoms like sneezing, runny nose, and itchy eyes.
Respiratory Issues: Mould can cause irritation of the respiratory system, leading to asthma attacks, chronic coughing, and shortness of breath.
Infections: Some types of mould can cause infections, particularly in individuals with weakened immune systems.
Chronic Inflammation: Prolonged exposure to mould can lead to chronic inflammation in the body, contributing to more serious health issues over time.
Skin Irritation: Direct contact with mould can cause skin rashes and irritation.

One particularly alarming fact is that one in four people are unable to produce antibodies to fungi, making them more susceptible to the long-term health effects of mould exposure. Even small amounts of mould can have devastating consequences for those affected, making it crucial to keep your home as mould-free as possible.

Identifying Mould in Your Home

Mould can grow in hidden areas of your home, making it difficult to detect. However, there are several signs that can help you identify a potential mould problem:

Leaks: Check for leaks in your roof, plumbing, or walls. Mould can grow in areas where water is trapped, even if it is not immediately visible.
Subfloor Dampness: Mould often grows in basements and subfloors, especially if they are prone to flooding or moisture seepage through the foundation.
Water Damage: Look for water stains around windows, doors, and other areas where moisture might accumulate. In winter, condensation on cooler surfaces can also lead to mould growth.
Musty Odor: A strong musty smell in certain areas of your home can be an indication of active mould growth.

The Dangers of Using Biocides for Mould Removal

When it comes to removing mould, many people turn to biocides like chlorine bleach. While these substances can be effective at killing mould on surfaces, their use is not recommended as a routine practice during mould cleanup. According to the US Environmental Protection Agency (EPA), dead mould is still allergenic and can cause health reactions. Instead of relying on biocides, the best approach is to remove the moisture source and clean the mould thoroughly from the property by professional mould remediation..

Practical Tips to Prevent Mould Growth in Your Home

Preventing mould growth in your home requires proactive measures to control moisture and improve ventilation. Here are some practical tips to help you keep mould at bay:

Control Humidity Levels

Mould thrives in moist environments, so it’s essential to keep your home dry and well-ventilated. Use extractor fans in bathrooms and kitchens, open windows when cooking or showering, and avoid drying clothes indoors. Keep humidity levels below 60% by using a dehumidifier if necessary.

Fix Leaks and Dampness

Moisture can enter your home through leaks, condensation, or rising damp. Inspect your roof, gutters, pipes, and walls for any signs of damage or dampness. Repair leaks promptly and ensure proper drainage. Use waterproof sealant or damp-proof membrane to prevent moisture from seeping through walls or floors.

Improve Ventilation

Good air circulation can help prevent moisture build-up and mould growth. Keep doors open, use ceiling fans or air conditioning, and avoid blocking air vents. If your home is poorly ventilated, consider installing additional vents or a mechanical ventilation system.

Use Mould-Resistant Materials

When renovating or building, consider using mould-resistant materials like certain paints, drywall, and insulation. These products are designed to resist moisture and mould growth, making them an excellent investment for areas prone to dampness.

Seal Windows and Doors

Ensure that windows and doors are properly sealed to prevent moisture from entering your home. Use weather stripping and caulking to keep out dampness, especially during the rainy season.

Use a Dehumidifier

If your basement is damp, get a dehumidifier to remove moisture from the air. If you have an air conditioner to run in the summer, it will remove some moisture as it cools the air. When using an air conditioner or dehumidifier, don’t keep your windows open if it is damp outside.

How to Remove Mould Safely

If you discover mould in your home, it's important to remove it safely to prevent further health risks. Here’s how to do it:

Use Protective Equipment

When working around mould, it's essential to use protective equipment to minimize exposure. This includes rubber gloves, eye goggles, and outer clothing that can be easily removed and laundered.

Clean Surfaces

Scrub all mouldy surfaces using a stiff brush, hot water, and a soap or detergent that does not contain ammonia. Collect used liquid with a wet/dry vacuum, mop, or sponge, and rinse the area clean with water. Make sure to dry the area thoroughly.

Allow Surfaces to Air Dry

Allow surfaces to air dry to maximize their contact time with the bleach, ensuring that any remaining mould spores are effectively killed.

Throw Away What Can’t Be Cleaned

When mould gets inside materials like carpets and mattresses, they cannot be cleaned and should be discarded. Always dispose of contaminated materials according to local regulations.

Wash or Dry Clean Fabric Items

You can remove mould from bedding, curtains, drapes, and clothes by washing or dry cleaning them if there is no visible mould. Once you have visible mould on porous items they are best to be disposed of.
