Can a Wet Basement Make You Sick?

A wet basement is an all-too-common problem that many homeowners face, particularly in regions with high groundwater levels or frequent heavy rainfall like West Virginia, which receives an average annual precipitation of approximately 45 inches.

To many homeowners, a damp basement may seem like a mere inconvenience, and the health risks associated with one are often overlooked. Homeowners should be aware of the potential hazards that arise from wet basements in order to protect their families and maintain a healthy living environment. 

In this article, we will look at the causes of wet basements, explore the health risks associated with them, and offer tips for prevention and remediation.  

By the end, you’ll be able to identify the potential dangers and understand the best steps needed to address them, ultimately keeping your home safe and comfortable for you and your loved ones. 

Common Causes of Wet Basements

Understanding the root cause of basement moisture issues helps homeowners take appropriate preventative measures and identify solutions. Here are some of the most common factors contributing to these problems:

1. Poor Drainage Systems

An inadequate or improperly installed drainage system is a leading cause of wet basements. Rainwater and melting snow can accumulate around the foundation of a house if gutters and downspouts are not properly diverting the water away from the home.  

The water then seeps into the ground, increasing the hydrostatic pressure against the foundation walls and eventually leading to moisture intrusion. 

2. Cracks in Foundation Walls

Cracks form along foundation walls due to a combination of hydrostatic pressure, the natural settling of the house, soil pressure, and freeze-thaw cycles.  

Wall cracks allow water to enter the basement directly. Even small hairline cracks can eventually lead to significant water infiltration if left untreated. 

3. Leaking Pipes

Plumbing issues, such as leaking pipes, can also be responsible for a damp basement.  

Water from these leaks can spread throughout the basement, increasing mold growth, and contributing to structural damage. Regular inspection and maintenance of plumbing systems help prevent these problems.

4. High Groundwater Levels

Homes located in areas with high groundwater levels are particularly susceptible to wet basements. In these cases, the water table may rise above the basement floor level, causing water to seep through the foundation and floor.  

This issue can be exacerbated during periods of heavy rainfall or rapid snowmelt.

5. Inadequate or Failing Sump Pumps

A sump pump is a critical component of many basement waterproofing systems. Its primary function is to collect and expel water from the basement to prevent flooding.  

If the sump pump is poorly maintained, improperly installed, or fails due to age or malfunction, the basement can quickly become inundated with water. 
Knowing what causes wet basements helps you fix them faster. At Basement Authority of West Virginia, we make a tailored plan for a lasting solution to basement water issues.

Health Risks Associated With Wet Basements

A wet basement can pose a range of health risks for occupants. The damp environment creates ideal conditions for the growth of mold, allergens, and irritants, and can also lead to structural damage and infestations. Here’s a closer look at the health risks associated with wet basements: 

Mold Growth

  • Types of mold commonly found in wet basements: Mold thrives in damp, dark environments, making a wet basement an ideal breeding ground. Some common types of mold found in basements include Aspergillus, Cladosporium, Penicillium, and the infamous Stachybotrys chartarum, also known as “black mold.” 
  • Health effects of mold exposure: Exposure to mold spores can lead to a range of health issues, especially for individuals with allergies, asthma, or weakened immune systems. Symptoms of mold exposure can include sneezing, runny nose, itchy eyes, skin rashes, and difficulty breathing. In severe cases, mold exposure can result in more serious respiratory problems and even toxic reactions.

Allergens and Irritants

  • Dust mites: These microscopic creatures thrive in humid environments and feed on organic debris, such as dead skin cells. Their waste products can trigger allergic reactions and aggravate asthma symptoms.
  • Volatile organic compounds (VOCs): Wet basements can also be a source of VOCs, which are chemicals emitted from certain materials, such as paint, adhesives, and carpeting. Exposure to high levels of VOCs can cause eye, nose, and throat irritation, headaches, and even damage to the liver, kidneys, and central nervous system. Evaporating moisture can produce a whole ecosystem of chemicals that can affect your health.

Structural Damage Leading to Safety Hazards

  • Weakened floor supports and beams: Prolonged exposure to moisture can cause wood to rot, weakening floor supports and beams. This can result in sagging floors, cracked walls, and even collapse in extreme cases, posing a serious safety risk. (Sidenote: if you have a crawl space rather than a basement, this can be a much bigger issue.) 
  • Compromised electrical systems: Excessive moisture in a basement can damage electrical systems, leading to potential fire hazards or electrical shocks. 

Pest Infestations

  • Insects attracted to damp environments: Wet basements can attract various pests and insects, such as cockroaches, silverfish, and termites, which can contribute to allergen problems and potentially cause structural damage to the home. 
  • Rodents seeking shelter and nesting areas: Damp basements provide ideal nesting sites for rodents like rats and mice, which can lead to health risks from their droppings and the spread of diseases. These pests also leave behind dander and exoskeletons that can cause respiratory problems and allergic reactions.

By being aware of these health risks, homeowners can take the necessary precautions and remediation steps to ensure a safe and healthy living environment. 

Tips for Preventing and Addressing Wet Basements

Prevention and proactive measures are key to keeping your basement dry and reducing health risks associated with moisture. Here are some tips to help you prevent and address wet basements: 

Proper Maintenance of Drainage Systems

Regularly clean gutters and downspouts to ensure they are free of debris and effectively directing water away from your home. Check that your french drains are working properly. Make sure the landscape around your house slopes away from the foundation to prevent runoff water from pooling near the walls. Extend your downspouts so that water is deposited at least six feet away from your home.

Sealing Cracks and Fixing Leaks

Inspect your foundation walls and basement floor for cracks or signs of moisture intrusion. If you use appropriate sealants to fill any cracks, remember that these solutions on their own are merely temporary, don’t address root causes, and may even make them worse without comprehensive solutions. Additionally, repair any leaking pipes or plumbing issues as soon as they are detected.

Installing or Upgrading Sump Pumps

Ensure that your home is equipped with a reliable sump pump system that is regularly maintained and tested. If your current pump is outdated or prone to malfunction, consider upgrading to a newer, more efficient model. In conjunction with french drains, basement pumps can make a world of difference. 

Dehumidification and Ventilation

Invest in a high-quality dehumidifier to reduce humidity levels in your basement and prevent mold growth. Ensure that your basement has proper ventilation, as this can help remove excess moisture and improve air quality. 

Regular Inspections and Cleaning

Periodically inspect your basement for signs of moisture, mold, and pests. Clean and declutter the area regularly to reduce the accumulation of dust, allergens, and potential food sources for pests. One check that often gets overlooked is checking moisture in or underneath basement carpets

By implementing these preventative measures and addressing any moisture issues promptly, you can maintain a dry, healthy basement and protect your home and family from the potential hazards of a wet basement.
