Types Of Basement Mold

Various types of mold will infest your basement. While they are all hideous, not all of them are toxic to humans.

Molds can be divided into two categories:

  • Allergenic
  • Mycotoxin/black

Allergenic molds usually pose no health risk unless you are extremely sensitive to molds or asthmatic. Black molds, on the other hand, produce a toxic chemical called mycotoxins and are particularly harmful to humans and pets.

Here are the common types of molds that can infest your basement.

Aspergillus

Aspergillus is one of the most common household mold species. There are different types of Aspergillus, and most of them thrive well indoors. Some of the Aspergillus molds are allergenic, but some are mycotoxin and should be removed by a specialist, especially if it is something like black mold.

This fungus is dark green and found on damp walls, ceilings, and even furniture. It flourishes in humid environments, but can also grow in areas that are dry with high levels of humidity or condensation.

    How Do You Prevent Mold From Growing On Concrete

    The best way to solve a mold problem on concrete is to prevent it from happening in the first place. One way to do this is by eliminating the key element mold needs to grow, moisture.

    For concrete patios, driveways, and walks, cut back foliage that creates shady areas on a driveway or walk that never see the sun.

    Also, check for cracks in the pavement that can collect water and cause mold growth. Fill these cracks using a concrete repair product.

    For areas where this isnt possible, consider treating the concrete with an acrylic sealer designed for outdoor use. This prevents moisture from penetrating the driveway or walk, eliminating the environment mold needs to thrive.

    For indoor areas, fix leaky pipes that are causing mold growth. For basements that flood, consider using a product such as Drylok to prevent moisture from entering the basement when it rains.

    If that isnt an option, a dehumidifier is also an excellent means of keeping the humidity level in a basement in check, preventing mold growth. Remove materials that can get wet and breed mold growth, such as cardboard, wood, cloth furnishing, and area rugs.

    Also, check the areas around the foundation of the home. If the earth is not properly graded to cause water to flow away from the house when it rains, grading may be required. Keep leaves and other debris from piling up around the foundation, which can trap water and direct it through the foundation and into the basement.

    Natural Ways To Remove Basement Mold

    There are numerous different ways to get rid of mold, but some chemicals used in the process have the potential to be harmful. Below are a few steps to remove mold naturally.

    Make sure the area in which the mold is growing is dry. Mold thrives on moisture, so fixing any leaks, cleaning up water, and ensuring that theres no humidity in the area should be your first step in removing mold.

    Create a mold cleaning solution to remove and clean the area the mold was on and around.

    Where Youll Find It Growing

    Mold on your basement or exterior walls occurs when water vapor in the air meets a cold surface and turns the vapor into a liquid. Bathrooms and laundry rooms develop mold because theyre typically very humid. Other humid areas include the walls and ceiling near humidifiers and any room with a hot tub or jacuzzi improperly installed indoors.

    Mold also grows where there is a water leak. Places like the cupboards under sinks are prone to mold. Once a pipe has leaked, theres a good chance mold will grow unnoticed within the wall until the problem requires expert removal.

    Preventing A Reoccurrence Of Mold

    As important as it is to clean mold on basement walls, it is equally important to take steps to keep the mold from returning. As mentioned, most mold problems in basements are due to a lack of ventilation and the presence of high humidity. You can alleviate the humidity in your basement by using a dehumidifier. These units can be found for under $300. I recommend a model that will self-empty, having pump-out capability or by continuously draining through a garden hose that can be directed down a drain. Here is more on selecting the right dehumidifier.

    Another preventative step you can take is to primer/paint the concrete walls with a mold resistant product after the removal process. An excellent choice is . These mold resistant products will range in price from $30-$50 per gallon. Most of these mold resistant primers and paints contain antimicrobial ingredients that help prevent mold re-growth in areas of high moisture content. Warning I never recommend attempting to cover, seal, or paint over mold in any situation.

    The goal is not to kill the mold but to completely remove it.

    Consider the following example: If you have a skunk living under your front porch, you have a problem. If you kill the skunk you havent solved your problem, you have just created a different problem. Now you have a dead skunk under your porch. The same goes for mold. Dont be happy with just killing it it needs to be removed.
