How to Prevent Mold Growth in Your Basement and Crawl Space

Basements and crawl spaces are both very susceptible to mold and mildew growth, typically due to the level of humidity and moisture in both areas. Mold is not something you want growing inside your home, as these spores can circulate around the house and get inside your respiratory system, causing allergy-like symptoms and other respiratory ailments over time. The best way to prevent mold growth is to reduce moisture levels in your crawl space or basement through proper waterproofing techniques.

Where Does Mold Grow?

Mold is a type of fungus that sends its spores out into the air, and when these spores land in moisture, they will begin growing, leading to black, brown or green splotches that we know as mold. Moisture or humid air creates the conditions for mold to thrive, and therefore it is often found inside bathrooms, sinks, and the humid areas of the home, like crawlspaces and basements. Crawl spaces are usually exposed to the bare dirt beneath the home, which allows groundwater to easily rise up into the crawl space. In addition, many crawl spaces have wide open vents to the outside due to antiquated building codes, and rainwater can enter through these vents to make your crawl space even more wet. The below-ground location of basements makes them more susceptible to water infiltration from the surrounding soil, especially during heavy rain or snowmelt. Poor ventilation can trap humidity, and condensation can form on cool basement walls and floors. Additionally, leaks from plumbing, groundwater seepage, and inadequate drainage systems contribute to persistent dampness. These moist conditions create an ideal environment for mold growth, which thrives in areas with high humidity and organic materials to feed on, such as wood, drywall, and insulation.

The Dangers of Mold Growth

Mold releases spores that can cause allergic reactions, respiratory issues, and other health problems, particularly in individuals with asthma or weakened immune systems. Mold growth produces musty odors that can permeate your home, making it unpleasant to live in. Crawl spaces often connect to your home’s ventilation system, spreading mold spores and musty odors throughout your house, negatively impacting indoor air quality. Mold can also deteriorate building materials in your basement or crawl space such as wood, drywall, and insulation, compromising the structural integrity of your home. Damp and moldy conditions can attract pests like termites and rodents, leading to further damage and health concerns. Mold issues can even decrease the value of your property and make it harder to sell. Addressing mold growth promptly is essential to maintaining a healthy living environment and preserving your home’s value. 

How Do I Prevent Mold Growth In My Basement?

The best way to prevent mold growth in your basement is by ensuring you are controlling the moisture levels. Make sure you have proper drainage around your home’s foundation, and that gutters and downspouts are directing rain water away from your home. If you have any cracks in your basement walls or floors, getting them sealed with caulk is necessary to keep water out. Dehumidifiers can eliminate the moisture in the air that causes mold growth, so keeping one in your basement can also prevent mold. Make sure your pipes are insulated to prevent mold-growing condensation, and make sure that your basement is properly ventilated. The licensed team of experts at Summit Waterproofing can provide you with all of these waterproofing solutions and more. In addition, we can perform regular inspections to make sure that your basement stays free of all moisture and mold problems. 

How Do I Prevent Mold Growth In My Crawl Space?

Just like with basements, the best way to prevent mold growing in your crawl space is controlling the moisture levels. Ensuring proper drainage around the home and installing dehumidifiers can help here as well, but the best way to prevent mold growth in the crawl space is by getting a crawl space encapsulation done. Crawl space encapsulation is the process of sealing off your crawl space with a vapor barrier, made of heavy-duty polyethylene. This vapor barrier covers the walls and floors, and it is sealed at all seams and joints. The vapor barrier is resistant against groundwater, preventing any moisture from getting inside and forming mold. In addition, crawl space encapsulations also seal off the crawl space vents, preventing rain water, melted snow or any other exterior forms of moisture from getting inside.
