How to Avoid Mold Spore Buildup in Your Facility

Mold can begin growing in as little as 24 hours under the right conditions. It can grow on a variety of surfaces, many of which are common in your home or business. There are some effective ways to prevent or decrease the chances of mold. Regularly cleaning your facility, using mold-resistant products, and monitoring the humidity are three easy ways you can avoid mold spore buildup in your building.

Regularly Clean Your Facility

One thing to consider is cleaning your air ducts regularly. This is particularly important if you have had issues with mold in the past. You should also check your ducts for rodents or insects, or see if your ducts have a large amount of dirt/dust in them


Regularly cleaning your carpet is another way to prevent mold growth. Mold grows in carpets either because the mold spores are already present through dirt and debris or because the dirt is damp creating the perfect environment for mold growth. Studies have shown that dirty carpet grows more mold over the same period of time under the same conditions as a clean carpet. Mold growth in carpets can be especially problematic in places with high humidity – namely basements. If the carpet is clean, regardless of the humidity, it is highly resistant to mold.


Because mold grows in damp conditions, it’s important to clean up any water spills immediately, no matter the size. The longer water sits on a surface, particularly one that could soak up the water quickly, the more likely mold will grow there. 


Vacuums that use HEPA filters are great for trapping mold spores and dirt. A regular vacuum tends to spit dirt back into the air. This can irritate some people’s allergies and can spread mold spores throughout your home. 

Build with Mold Resistant Products

If you are building or remodeling your home or business, it’s a good idea to look into mold-resistant building materials. There are several products designed to resist moisture and therefore mold.


Mold-resistant drywall, paint, wood, caulk, and sealant are all great options for preventing mold before moving in. These products are especially helpful in more humid environments such as bathrooms, kitchens, mudrooms, and basements.

Keep the Humidity Low

Some rooms and buildings are more prone to higher humidity, but keeping the humidity lower in a building is important for preventing mold growth. The ideal humidity in a home is 30-50 percent. Anything lower or higher can be damaging to your building. Low humidity can lead to damaged electronics, paint, or wood floors and provides a good environment for viruses to thrive. Staying within the 30-50 percent range is ideal.

High humidity can be obvious because of that infamous sticky feeling, but it never hurts to check. If you are sweating in your home, that is a good sign you should lower your humidity. Another option is to purchase a hygrometer. This will tell you the humidity level in your building and give you a good idea of where to start. 


Some ways to reduce humidity in your building include:

  • Run your air conditioner.

  • Use exhausts/ventilation in your bathrooms and kitchen.

  • Fix any leaks you might have in the building.

  • Keep your gutters clean.

  • If outside isn’t very humid, open a window.

  • Use a dehumidifier.

  • Relocate your indoor plants as they can put a lot of moisture back into the air.


Regularly cleaning your facility, building with mold-resistant materials, and keeping the humidity low are easy ways to prevent mold from growing in your building. Because mold does not take long to begin growing under the right circumstances, you need to be diligent about watching for and preventing mold growth and fixing any water damage.
