Top Sources of Mold

We will be discussing the primary sources of mold that are commonly found in homes. As we all know mold needs moisture and food (porous materials) to grow. Mold also likes dark humid environments. Some key causes to look out for mold are:

1. Leaky Appliances

Daily wear and tear to your appliances can cause leaks or splits that can allow moisture to escape. Unfortunately most appliances have the pipes and hoses hidden out of sight running inside walls or cabinets. So it may take some digging around to find any leaks. We recommend checking regularly for loose washers or leaky hoses. 

2. Air Conditioning Units

The condensation from an air conditioning unit creates moisture for mold. On top of that it also sucks in air from the outside that contains dirt and pollen which are attractive materials for mold. You can help minimize mold growth by running it everyday for at least 10 minutes. When it sits for long periods of time it is more likely to grow mold. When not in use like during winter season you should remove it and store in a dry place. 

3. Water Intrusion

It is beneficial to check your ceilings and cracks of your windows for any water getting in. This can be a sign of poor building construction so you may need a professional to diagnose and treat the issue. 

4. Window Sills

This area is subject to higher levels of moisture and humidity along with dirt that is a valuable source for mold. 

Next, we will discuss some locations in your home that have a higher chance for mold to grow.

1. Basement

Being that most basements are located on a sub-level, moisture is constantly part of its environment. The humidity level is much higher and typically not well ventilated leaving humidity to linger longer. Any cracks in foundation can also add to the issue. 

2. Wallpaper

If wallpaper is peeling it is likely that it has mold growing behind it. 

3. Attic

The attic of a home is home to many air flow sources like dryer vents, plumbing vents, and kitchen/bathroom. All of these constantly pump moist air into the attic accompanied with all the inevitable dust found there makes a perfect environment for mold. 

4. Crawlspace

Like a basement the crawlspace also has a higher relative humidity. The soil in the crawlspace will absorb and lock in moisture and when it dries it will evaporate adding moisture to the air.
