Mould growth is a common problem that many homeowners face. Not only is it unsightly and can damage building materials, but it can also pose health risks if left untreated. In this article, we'll provide you with valuable tips to help you get rid of and prevent mould growth in your house. By following these tips, you can ensure a healthier living environment for you and your family.

Understanding Indoor Mold Growth

Before we dive into the tips, it's essential to understand how indoor mould growth occurs. Mould thrives in warm, damp, and humid environments. It reproduces by releasing tiny spores into the air, which can then settle on various surfaces and grow. Common areas where mould can develop include bathrooms, kitchens, basements, and areas with poor ventilation.

What are the Most Common Indoor Molds?

There are various types of indoor moulds, but some are more common than others. The most prevalent indoor moulds include the following:

Each type of mould has its characteristics and potential health risks, making it crucial to address any mould growth promptly.

Signs that Your Home Has a Mold Problem

Identifying a mould problem in your home is essential to take immediate action. Some signs that indicate the presence of mould include a musty odour, visible mold growth on walls or ceilings, discoloured patches, and peeling wallpaper or paint. The presence of mould mites may also indicate mould problems, as the mentioned arthropods feed on mould.

Health Problems Caused by Indoor Mold Growth

Mould can have severe health consequences, particularly for individuals with respiratory conditions or weakened immune systems. Here are some health issues that can be caused by indoor mould growth:


Exposure to mould spores can trigger asthma attacks in individuals who already have this condition. The presence of mould in the house can worsen asthma symptoms, leading to coughing, wheezing, and difficulty breathing.

Allergic Reactions

Many people have mold allergies. When exposed to mold spores, people with mold allergy may experience symptoms such as sneezing, runny nose, itchy eyes, and skin rashes. These allergic reactions can be uncomfortable and impact overall well-being.

Opportunistic Infections

In some cases, mold exposure can cause opportunistic infections, particularly in individuals with a weakened immune system. These infections can range from mild respiratory infections to more severe conditions, depending on the type of mould and the individual's health.

How to Get Rid of Household Mold Growth

Now that we understand the risks associated with mould growth, let's explore some effective ways to kill mold in your household:

Use Protective Gear

To avoid direct contact with mould and mold spores and prevent inhalation, it's important to wear gloves, goggles, and a mask. These protective measures help minimise the risk of exposure to potentially harmful mould spores.

Gloves provide a barrier between your hands and the spores, while goggles protect your eyes from any airborne particles. The mask helps filter out the spores, preventing them from being inhaled.

Clean the Affected Area

For small areas affected by mould, you can use a mixture of water and detergent to clean the surfaces. Scrub the affected area thoroughly, making sure to remove all visible mould. Use a brush with stiff bristles to reach into crevices and remove any stubborn mould stains.

Disinfect Mouldy Surfaces

After cleaning the moldy surfaces, it's important to disinfect them to kill any remaining mould spores. You can use a solution of bleach and water, following the manufacturer's instructions for the appropriate dilution. Apply the solution to the affected areas and let it sit for a few minutes before wiping it clean.

Ensure Proper Ventilation

Once you have cleaned and disinfected the mouldy surfaces, it's crucial to allow them to air dry completely. Proper ventilation will help prevent the growth of mould in the future. Open windows and use fans to circulate fresh air and facilitate the drying process.

Sort Out and Dispose of Unsalvageable Items

In some cases, mould may have penetrated porous materials, making it impossible to clean and eliminate. If you come across items like carpets, furniture, or drywall that are extensively affected by mould, it's best to dispose of them to prevent further contamination and ensure the complete removal of mould from your home.

When to Contact Professionals for Your Mold Problem

While these tips can be effective in dealing with small areas of mould growth, there are instances where it's best to seek professional help. Consider contacting a professional mould cleaning service for your mould problem in the following situations:

How to Prevent Mold Growth

Preventing potential mould growth is key to maintaining a healthy living environment, which may be done by focusing on controlling moisture and indoor humidity. Here are some essential tips to help you prevent mould growth in your house:

Prevent Excess Moisture

Mould grows and thrives in damp environments, so it's crucial to remove moisture and keep your home as dry as possible. Fix any water leaks promptly, whether it's a leaking pipe, roof, or window. Dry wet areas within 24 to 48 hours to prevent mould from taking hold.

Maintain Proper Air Circulation

Proper air circulation is vital to prevent stagnant air and excess humidity. Ensure that your house has adequate ventilation, particularly in areas prone to moisture, such as bathrooms and kitchens. Use exhaust fans or open windows when cooking, showering, or using appliances that generate moisture.

Consider Using a Dehumidifier

If you live in a particularly humid climate or your house has persistent moisture issues, consider using a dehumidifier. A dehumidifier will help reduce excess relative humidity, making it less favourable for mould growth. Empty and clean the dehumidifier regularly to prevent mould from forming inside.

Address Moisture Problems Before Finishing Your Basement

Basements are susceptible to mould growth due to their typically damp and dark environment. If your basement is prone to moisture problems, it's best to avoid finishing it unless you can address the underlying issues effectively. Finishing a damp basement can trap moisture and lead to extensive mould growth.

Final Words

Mould growth in the house can be a significant concern, affecting both the aesthetics and the health of your living environment. By understanding the causes, signs, and health risks of mould growth, you can take the necessary steps to get rid of and prevent mould in your home.
