Is Black Mold Dangerous?

Black mold is one of the most widely discussed types of mold found in homes and buildings. Many homeowners become concerned when they discover dark mold growing on walls, ceilings, or other surfaces.

While mold can appear in many colors and forms, certain types of dark mold—often referred to as black mold—can raise concerns about indoor air quality and potential health effects.

Understanding what black mold is and whether it poses risks helps homeowners take appropriate action when mold appears.

What Is Black Mold?

The term “black mold” commonly refers to Stachybotrys chartarum, a type of mold that can grow on materials containing cellulose such as:

• drywall
• wood
• insulation
• paper-backed building materials

This type of mold often appears dark green or black and tends to grow in areas with long-term moisture exposure.

Why Black Mold Develops

Black mold typically develops when moisture remains present for extended periods.

Common causes include:

• water damage from leaks or flooding
• plumbing leaks behind walls
• roof leaks during storms
• high humidity levels
• poor ventilation in bathrooms or kitchens

Homes in Round Rock, Cedar Park, and North Austin may experience mold growth if water damage is not addressed quickly.

Potential Health Concerns Related to Mold

Exposure to mold can affect individuals differently depending on sensitivity and the level of exposure.

Possible symptoms may include:

• nasal congestion
• coughing or sneezing
• eye irritation
• throat irritation
• worsening asthma symptoms

People with allergies, respiratory conditions, or weakened immune systems may be more sensitive to mold exposure.
