8 Effective Ways to Prevent Mold Growth in Your House

  • Written by

Mold and mildew can grow easily in areas with high moisture content and can be a challenge to remove completely. It can grow almost anywhere in the house, such as the toilet, drywall, ceiling, carpet, and pipes. The mold spores can trigger serious respiratory diseases such as asthma, bronchitis, and even pneumonia.

Although not all types of fungi are detrimental to health, there is a specific type like the black mould that has a serious effect on health and can be removed by professionals only. Moreover, some people are more sensitive to mildew and mould than others. For example, infants, the elderly, people with a compromised immune system, and chronic lung diseases are more sensitive to mold spores than others.

Once the mold starts to grow, it can be challenging to control its growth, and the best way to deal with it is to prevent it from happening. Here are some things you can do to prevent its growth.

Dry Wet Areas Immediately

One simple yet easy way to prevent mold is to wipe any wet area. Mildew and mold need moisture to thrive, and wiping an area to dry will keep any growth opportunity. A spill on the carpet, leaky pipes, and or broken ventilation system should be fixed immediately. This also includes cleaning your gutters and downspouts to avoid the accumulation of water.

Improve ventilation

Poor indoor airflow causes moisture to build up around the house. Improving airflow inside the house can be done by opening the windows and door of each room. Proper ventilation is important as this will allow clean air to flow in and help bring in the air that will help reduce dampness and musty air. You can also install exhaust fans in high moisture areas such as the kitchen, laundry room, and toilet.

Maintain proper humidity

Maintaining humidity at home will help you control potential mould growth, and you can do this by using a moisture meter. A range of 30% to 60% of humidity is considered safe. However, if you do not own any moisture meter, simply observe any condensation around the house. When this happens, wipe to dry and find what’s causing the moisture. You can also use a dehumidifier to reduce the presence of moisture.

HEPA filtration

Moulds can easily grow on carpet and floor, but using a vacuum with a HEPA filter can help remove the spores. You can also use this type of vacuum to clean air vents or other areas prone to mold. Aside from the vacuum, there are also HEPA air purifiers that you can use in rooms that have poor ventilation and are prone to dampness.

Get mould-resistant products

If you are renovating or building a new home, choose mould resistant materials. There are paints, drywall, and sheetrock that inhibit the growth of these fungi. These materials are effective because it does not absorb moisture thus highly effective in areas like kitchen, laundry areas, and basement. You can also do bathroom waterproofing to prevent any water absorption.


Decluttering can help reduce the chances of mould growing in your home, especially during the cold rainy season. Donate any unused clothing, recycle stuff or throw away things that can’t be used anymore. Clutter is a conducive place for mildew and mould to grow because the more congested space is, the less air circulation.

You can do a complete clearing and cleanup as the cold season approaches. Moreover, fungi thrive in materials that absorb moisture, such as clothes, newspapers, and cardboard. Getting rid of and avoiding the accumulation of these types of materials at home would significantly improve air quality.

Avoid drying clothes indoors.

Drying your clothes indoors can increase moisture content in the house. Without proper ventilation, the moisture evaporates and settles on walls and ceilings. If you prefer drying your clothes indoors, allow plenty of air circulation by opening windows or using vents to help pull out moisture from the room. You can also opt for a tumble dry machine. If possible, dry your clothes in an open space area with plenty of air circulation.

Look for leaks

Leaks are often the cause of mildew and mould growing in the house. Do regular checks around the house, particularly in the kitchen, toilet, roof, and gutters. Preventing leaks is easy yet one of the effective ways to prevent any fungi growth. If you notice any discoloration on the ceiling or wall or a musty smell around the area, it is an early sign of mould growth. Deal with the leak as soon as possible.


Mould and mildew can be prevented when areas are kept dry and clean, ensuring proper ventilation, checking for any leaks, and frequent decluttering to improve air circulation. However, once the fungi start growing, it can be difficult to remove them altogether, and this will eventually cause more damage, affect health and cause a significant amount of money for repair.
