Can Mold Grow on Concrete?

Author: Gabrielle Marks


Mold CAN  grow on concrete.

More Info: Though mold technically can grow on concrete or any surface that can provide suitable conditions such as temperature, moisture, and food, if you are seeing what looks like mold on your concrete, you may be viewing minerals and salts that can be deposited from moist concrete and is often mistaken for mold.

Though mold may not be present on the wet concrete itself, moisture can migrate through wet concrete contributing  to mold growing on construction materials that are attached to the concrete such as walls, cabinets, and wood flooring.

Common Sources of Mold

Mold thrives best in conditions that are moist, warm, and humid.  You will likely find mold in areas of condensation buildup such as a window in a room where the exterior is cold and the interior is warm. Air conditioning is another common cause of mold growth in and around ductwork and vents.  Other common conditions in the home that encourage mold growth are shower steam, humidifiers, flooding, water leaks, and damp basements.

Mold Exposure Symptoms

Long-term exposure to indoor mold can cause symptoms in otherwise healthy people.  Symptoms are generally respiratory and can include coughing, wheezing, and upper respiratory tract infections.  For those with asthma, exposure to mold can induce asthma symptoms.   Those that are sensitive to mold exposure can experience skin and eye irritation, wheezing, and nasal stuffiness.  Those with mold allergies can experience more severe symptoms including fever, shortness of breath, and mold developing in the lungs.
