Worst Attic Mold You Can Have
Attic mold often appears in white, green, brown, or black. Regardless of color, all mold feeds on organic materials like wood, cardboard, or dust and can damage structures over time.
Mold spores are everywhere and feed on organic material, causing rot. While helpful in nature, mold damages homes and stored items. Three types pose health risks, regardless of color or smell. If you find attic mold, remove it promptly and safely.
| Type of Mold | Description | Health Effects |
|---|---|---|
| Allergenic Mold | Most common; feeds on organic material | Flu-like symptoms, worsens asthma, triggers allergies |
| Pathogenic Mold | Affects people with weakened immune systems | Infections, swelling, skin irritation, higher risk for immunocompromised persons |
| Mycotoxic Mold | Most dangerous; produces mycotoxins | Can cause brain damage, depression, miscarriages, joint pain, cramps |
| Indicator | Description |
|---|---|
| Musty Odor | Earthy, damp smell noticeable in attic |
| High Humidity | Attic feels stuffy or moist |
| Stains | Black, white, green, or brown discoloration on wood or insulation |
| Condensation | On attic windows, pipes, or uninsulated ducts |
| Health Symptoms | Allergic reactions after attic exposure (sneezing, fatigue, coughing, etc.) |
Black Mold
Black mold has the reputation of being toxic. According to the Centers for Disease Control (CDC), mold itself is not toxic. It is the Volatile Organic Compounds (VOC) that they give off. All black mold is not toxic. Without professional testing, you do not know what you have.
White Mold
White mold is easy to see on wood and drywall–especially if it becomes a large infestation. It is usually responsible for allergic reactions.
Attic mold is usually less serious than mold in basements or living areas. Not always. If it works its way through ceiling drywall or the attic hatch is left open, attic mold starts growing where people live. Well ventilated attics have fewer mold problems. The proper amount of insulation and vapor barriers reduce mold growth.
Inspect attics regularly or have a professional do the job. At least once a year. Every six months is better. Remove any mold immediately. Professional mold removal is usually the safest option–especially for large infestations.
Smaller patches can be a DIY project. Take it seriously because it could be any type of mold. Wear proper clothing and equipment. Hazmat-type coveralls with hood. Gloves. Safety glasses. Respirator with HEPA filters because breathing in mold spores can cause serious infections.
After the mold is removed and the attic is sanitized, determine the causes of attic mold and how to prevent attic condensation. A little planning and effort reduces or eliminates mold growth in the attic.
