Basement Mold

Mold develops when excess moisture is present in your basement. Moisture could lead to structural damage while mold simultaneously becomes a health risk.

Have you ever gone into your basement only to be hit by a wave of musty odors? This might be a sign that mold is growing in your basement, and it’s more common than you think. Since basements are located below the ground, it’s easy for moisture to seep into the walls as it is absorbed by soil. Thankfully, Mount Valley has plenty of basement waterproofing solutions that can prevent mold. 

What Causes Mold to Grow in Your Basement? 

Mold can only grow in places with high amounts of moisture, and there are a few ways for moisture to get into your basement. Here, we’ll identify a few ways that moisture infiltrates your basement so you can be better prepared as a homeowner. 

internal plumbing leak

Leaky Pipes

Plumbing leaks are a problem no matter where they occur in your home, but they can impact your basement even more as water drains into the walls and seeps down below your home. Water can saturate the walls and floors of your basement, causing humidity to rise and providing mold with the perfect conditions to grow. 

Mold also requires damaged organic material to survive, so when water causes damage to the wooden beams in your basement walls, mold spores have a field day. If a plumbing leak occurs at any time in your home, make sure to check the basement for water damage.

Hydrostatic Pressure

Another factor that can cause mold to grow in your basement is a phenomenon known as hydrostatic pressure. This natural process describes how water exerts greater and greater pressure as it drains further below the surface. When heavy rain is absorbed into the soil close to your basement, the growing pressure can push the soil against the basement walls. 

As the pressure continues to build, it may cause your basement walls to bow outward and crack, allowing groundwater to leak inside. Suddenly, your basement is exposed to moisture and humidity will start to climb – leading to mold growth once again. 

leaking window well

Damaged or Faulty Window Wells

Window wells are built as a barrier between basement windows and water (either from exterior drainage or precipitation). However, window wells can be damaged over time without proper maintenance which can spell disaster for your basement. Without the proper protection, water will cause damage to your basement window, potentially breaking down the window frame and allowing moisture to get into the basement. 

 Mold and mildew can start growing on the damaged windowsill and eventually spread throughout your basement as humidity continues to rise. Make sure your window wells are functioning properly and call a professional to inspect your basement if you notice a damaged or moldy window. 


Mold growth can cause allergies, disease, and, in the worst-case situation, life-threatening difficulties to breathing. If left uncontrolled, mold can harm you and others living in your home. Not to mention, mold can eventually spread into the rest of your house as spores spread into the airflow, affecting the air quality as well. Moist areas like bathrooms, kitchen cabinets, and behind washing machines might experience mold growth. Call a professional to handle the mold problem in your home. 

Don’t try to get rid of mold on your own, even with home remedies like bleach. We recommend contacting a professional mold removal service. Coming into close contact with mold without the proper protection can be dangerous for your health. Plus, using the wrong mold remediation techniques won’t solve the problem and could cause mold to spread more. To keep yourself safe, it’s best to call an expert. Plus, once the mold is removed, Mount Valley can employ basement waterproofing solutions that prevent mold from growing ever again. Safety is always our highest priority when it comes to our customers. 

Mold needs two things to grow: high humidity and decaying organic material. In order to thrive, mold needs an environment with a moisture content between 55%-60%. Measuring the amount of humidity in your basement can show you if it’s providing the right conditions for mold growth. Organic materials are present all throughout our homes, including the wood and drywall used to build the walls or ceiling of your basement. When these structures become exposed to high amounts of moisture, they start to decay and provide mold with a space to grow. Waterproofing your basement is essential if you want to avoid mold infestation.
