1. What exactly are molds?
2. How do molds grow?
3. What do molds like to eat?
4. What are toxic molds?
5. What is hidden mold?
6. What are the five levels of mold contamination?
7. What’s involved in mold removal?

What Exactly Are Molds?

Molds, also known as mildew, are fungi that thrive on wet surfaces. They play a crucial role in the natural environment by breaking down dead organic matter, such as fallen leaves and trees. However, when molds appear in buildings, they become hazardous materials requiring professional removal.

How Do Molds Grow?

Molds reproduce through spores carried by dust. These spores land on surfaces and grow into colonies when conditions such as temperature, moisture, and nutrients are optimal. Common causes of indoor mold growth include flooding, leaky roofs, plumbing issues, and condensation from HVAC systems.

What Do Molds Like to Eat?

Molds feed on materials like plywood, drywall, cabinetry, wood flooring, and carpet padding. Carpeting often provides a prime food source due to the organic dust particles it retains.

What Are Toxic Molds?

Toxic molds produce mycotoxins, chemicals that can cause mycotoxicosis when ingested. A well-known toxic mold is Stachybotrys chartarum, commonly referred to as black mold. Exposure can result in various health issues, from respiratory problems to serious illnesses.

What Is Hidden Mold?

Molds often hide behind wallpaper, paneling, drywall, or under carpets. These hidden molds are usually detected through their odor and associated water damage.

What Are the Five Levels of Mold Contamination?

The EPA categorizes mold contamination into five levels:

• Level 1: Less than 10 sq. ft. DIY cleanup with protective gear is sufficient.
• Level 2: 10–30 sq. ft. DIY is possible, but professional help is recommended.
• Level 3: 30–100 sq. ft. Requires professional remediation.
• Level 4: Over 100 sq. ft. Entire building contamination; only professionals should handle this.
• Level 5: HVAC contamination. Shut down systems and hire professionals immediately.

What’s Involved in Mold Removal?

Mold remediation typically involves:

1. Observation: Identifying mold-infested areas.
2. Sampling: Conducted when necessary by trained professionals.
3. Containment: Preventing the spread of mold spores during cleanup.
4. Cleanup and Air Filtration: Using specialized techniques and equipment.
5. Disposal or Removal: Determining whether infested materials require hazardous waste disposal.
6. Sanitization and Deodorizing: Cleaning surfaces to prevent reinfestation.
7. Post-Remedial Recommendations: Guidance on preventing future mold issues.

What’s the Upshot?

Except for minor infestations, mold remediation is best handled by professionals. Improper removal can worsen the problem, leading to increased costs and regulatory complications.
