What causes mould?

Mold is a type of fungus that is always present in our environment. Its spores are always floating in the air, and when they settle on surfaces where there is excess moisture and organic matter to feed on, they begin to grow. You can learn more about how mold grows in this blog.

The main cause of this excess moisture is high humidity. Warm, humid air carries a lot of water vapor that condenses on cold surfaces such as walls and windows, making them damp. This is why it is very common to find mold growing on and around windows.

Another cause is penetrating and rising moisture. Damp spots caused by leaks or spills can also give way to rapid mold growth if not addressed promptly. Poor ventilation and airflow can trap moist air, allowing it to make surfaces damp.

Why mould comes back after treatment

Mold is a stubborn problem that requires expertise and specialized equipment to eliminate. The main reason it comes back is that mold spores are microscopic and can easily spread through air currents or attach themselves to people and pets. If any mold is left behind during mold cleaning, it may start growing again.

Many people fail to diagnose the cause of mold in their homes either, so after the mold is removed, the conditions for mold growth are still there.

Many DIY mold cleaning methods, such as bleach cleaning, fail to get rid of mold and may even encourage it to spread. For example, cleaning can worsen mold and release spores into the air.

Ineffective cleaning techniques also remove visible mold at the surface level. They do not address the root causes such as infestations hidden behind walls or inadequate ventilation systems.

How to stop mould coming back

First, make sure you keep humidity levels below 50% throughout the day using dehumidifiers and air conditioners.

Make sure you ventilate rooms that are prone to high humidity, such as bathrooms or kitchens, regularly as well. This includes opening windows during or after cooking and washing, or installing exhaust fans to bring in fresh air.

Cleaning your home frequently can help remove any dirt, dust, or dead insects that mold can feed on. Don’t forget to get any leaks or other sources of moisture repaired by professionals right away and dry out any moisture they may be causing.

You should also avoid drying clothes indoors as water vapor can make the air damp.

It’s recommended to use a mold-resistant paint, especially in the bathroom and kitchen. You can learn more about the best ways to prevent mold growth here.

How to remove mould

You shouldn’t attempt to clean mold yourself unless you have the training, personal protective equipment, and specialized tools to do so. Without personal protective equipment, for example, you could end up inhaling or touching harmful spores. This can put you at risk for various health problems, including allergies.

Many household cleaners don’t completely eliminate mold but only bleach it or get rid of surface spores. This can give you false reassurance while the problem persists beneath the surface.

Professional mold removal professionals can give you peace of mind that they will remove all mold while effectively containing its spread. They can even determine the specific cause of mold in your home and advise on the best way to prevent it from returning.
