The Top Causes of Mould Damage

Mould is present in a lot of air and surfaces, especially in spaces that are humid and damp. It causes a variety of health concerns, such as nasal stuffiness, throat irritation, coughing, wheezing, eye irritation, and more. Unfortunately, these conditions are worse for people who already have a compromised immune system. Mould can occur both inside and outside your home, with its presence being the source of a lot of damage when it forms.  By addressing the areas known to contribute to mould damage, you effectively prevent future mould issues in your home.


Large amounts of water result in an immediate increase of moisture levels. Because the amount of water entering a space is much more than usual, mould has the potential to grow in as quickly as 24 to 48 hours. By calling a restoration company as soon as flooding has occurred, you prevent the additional issues associated with mould. A professional restoration company works quickly to remove the excess moisture that causes mould growth.

High Humidity Levels

Humidity refers to the amount of moisture content found in the air. Many factors contribute to the humidity found in a home, including local climate, the amount of rain, lots of cooking, hot showers, and a lack of ventilation. Although you can’t control the local climate, you can implement ventilation to reduce the effects of humidity in your home. To measure the amount of humidity, purchase a humidity meter at a local hardware store. Humidity levels in the home should be kept around 55%.

To increase ventilation in the home, open windows and doors regularly for improved air flow.  Another option is to install fans to boost circulation.

Household Leaks

Pipes and roofs are the two most common leaks found within a home’s structure. Oftentimes, these leaks go undetected for long periods of time because their damage isn’t always visible. Leaking pipes can be hidden within walls, which provide a dark and damp space for mould to grow. Regularly inspect your walls for any stains caused by water damage. These stains usually change the wall’s texture and result in the discolouration of paint. If you suspect that your home has undergone water damage caused by a leak, it’s paramount that you contact a professional restoration company to safely assess the damage.

Mould Damage in Basements

An unfinished basement provides the ideal climate for mould to grow; it’s dark, damp, and most likely experiences a high humidity level due to a lack of air circulation. Basements are also subject to flooding in the event of extreme weather or broken pipes. Be sure to check your basements regularly and get a professional restoration company to test for mould damage if your basement has flooded recently or in the past.
