Household Mold: Common Areas Of Growth and Prevention Steps

​Mention mold and it’s likely to cause shudders from anyone hearing the word.  What is mold and what causes mold to multiply in your home?

Molds are a type of fungus. Outdoors, they are beneficial and break down dead organic matter.  Indoors, it’s an entirely different story. 

They reproduce by releasing microscopic spores into the air.  When conditions are right, spores grow into mold and can multiply quickly in just 24 to 48 hours. 

At the very least, mold can cause unsightly spots and damp, musty odors.  However, for people who are sensitive to mold, mold can cause serious health problems.  Even breathing the spores can trigger an attack. Symptoms include these:

Household Mold Prevention - What Are the Causes of Household Mold?

All homes have the essential ingredients to be a giant petri dish for mold, like:

Whether it’s from a water leak, flooding or high levels of humidity, the addition of moisture into the mix triggers mold to grow and multiply.

Household Mold Prevention - Common Areas Where Mold Can Be Found

The best way to protect your home against mold is to know where it can commonly grow and keep an eye on those places.  Armed with the understanding of the causes of household mold, you can take preventive measures before it brings damage to your home and affect your family’s health.


Often damp, warm and humid, the bathroom offers the perfect environment for mold growth. In particular, pay attention to the following specific places where mold can easily multiply:

Another area where mold can take root is in the kitchen. It can turn humid when the stove is in use and with hot water running or boiling on the stove, as well.  Add in plenty of surfaces and you have the ideal environment for mold growth. 

In the kitchen, pay specific attention to these places:

Microwaves and stoves, if not kept clean and dry are also ideal mold breeding grounds. The back of the stove where food crumbs can accumulate can likewise harbor molds.

Attic, Basement and Garage

If there’s any place where mold growth in the home is highly probable, it would probably be in your attic, basement or garage. These offer the perfect breeding ground for mold - dark, damp, warm, and with poor ventilation. 


The attic is where the home’s ventilation systems are located. And this poses a serious problem because mold can spread quickly throughout your home through the vents.  In the attic, here are the places to pay close attention to for mold growth:

Basements are notoriously damp and if your basement smells musty, you can almost bet that there’s mold there somewhere. However, this need not be the case if you know where to look for possible breeding grounds. Here are the places to inspect for mold growth:

The garage is exposed to the elements and is most vulnerable to rain and flooding, and resulting water damage. It can also become damp with leaks coming from the roof and even moisture each time your car comes in from the rain.

If you store old items in the garage, or even cleaning supplies, this makes it more likely to harbor mold growth.  Here are the most likely places to look for mold:

There are also other key areas to watch for mold.

Ceilings and Walls

Undetected leaks may cause mold to form within walls or in ceilings.  If you observe a musty, earthy smell, there’s likely to be mold hiding in there somewhere. 

Watch out for water spots or stains as these are indicators of leaks.  If you notice these, it is best to call on the professionals to address the water damage.  

As mentioned above, mold can grow very fast and mold remediation may become necessary if water damage and ensuing mold growth is not addressed immediately.

Carpets, Fabric and Upholstery

Carpets can harbor mold even if there are no telltale signs.  Mold can be hiding underneath on the carpet padding. It is important that any spills or leaks be dried thoroughly to prevent mold growth.

Fabrics such as curtains, towels or furniture coverings are porous and can harbor mold within their fibers. It is important to keep these items clean and dry to keep mildew from forming.  And when mildew sets in, mold growth isn’t far away. 

HVAC System

It is important to ensure that your air conditioning and heating systems are carefully monitored for mold.  If your home’s ducts get moldy, spores can spread all throughout your home quickly. 

It is important to check your AC to ensure that it is draining properly. Filters also need to be inspected to make sure that moisture is not accumulating.
