Dead Mold Is Harmful Mold Part 2

Posted by Arthur Jackson on May 20th 2024

When mold invades our homes, particularly in crawl spaces and basements, it’s not just an aesthetic or structural concern—it’s a health hazard. Mold can trigger allergies, asthma, and other respiratory issues. Naturally, the priority is to get rid of it as quickly as possible. However, what many homeowners don’t realize is that not all mold remediation methods are created equal. In fact, some companies use harmful chemicals to kill the mold but fail to remove it, leaving a dangerous legacy behind.

The Quick Fix: Killing Mold with Chemicals

Some mold remediation companies opt for the seemingly quick and efficient method of spraying chemicals to kill mold. These chemicals, often touted for their effectiveness, include biocides and fungicides. While they may indeed kill the mold, the approach is inherently flawed. Here's why:

  1. Dead Mold as an Allergen: Dead mold spores can be just as harmful, if not more so, than live ones. When mold dies, it doesn’t disappear; it just becomes dormant. These dead spores can still cause allergic reactions and respiratory problems when inhaled. Without physically removing the mold, the allergens remain in your home, posing a continuous health risk.
  2. Chemical Residues: The chemicals used to kill mold are not without their own risks. Many of these substances are toxic and can affect indoor air quality long after the initial application. Residual chemicals can volatilize into the air, leading to potential health issues such as headaches, dizziness, nausea, and long-term respiratory conditions.
  3. Indoor Air Quality (IAQ) Concerns: A common chemical used in mold remediation is chlorine bleach. While effective at killing mold on hard, non-porous surfaces, bleach can produce fumes that irritate the eyes, skin, and respiratory tract. Other chemicals may have similar or even more severe effects on indoor air quality. Prolonged exposure to these chemical fumes can be particularly harmful to children, the elderly, and those with preexisting health conditions.

The Importance of Proper Mold Removal

Effective mold remediation should encompass more than just killing the mold—it should also involve removing it and ensuring that the indoor environment is safe and healthy. Here are the steps that should be taken:

  1. Containment: Proper containment ensures that mold spores do not spread to other areas of the home during the remediation process. This often involves sealing off the affected area and using negative air pressure.
  2. Physical Removal: Physically removing mold-infested materials is crucial. This might mean cutting out sections of drywall, removing carpet, or even pulling up floorboards. Simply spraying a chemical and leaving the mold behind is inadequate.
  3. Cleaning and Sanitizing: Thorough cleaning of the affected area with non-toxic, mold-specific cleaners is essential. This includes using HEPA vacuums to capture any remaining spores and ensuring that all surfaces are cleaned and sanitized.
  4. Addressing Moisture Issues: Mold thrives in damp environments, so it’s imperative to identify and rectify the source of moisture. This might involve repairing leaks, improving ventilation, or installing dehumidifiers.
  5. Air Quality Testing: Post-remediation air quality testing can help ensure that the mold has been effectively removed and that the air in your home is safe to breathe.

Choosing the Right Mold Remediation Company

When selecting a mold remediation company, it’s important to ask the right questions and look for key practices:

  • Do they physically remove mold, or do they only kill it?
  • What chemicals do they use, and are they safe for indoor air quality?
  • Do they offer air quality testing post-remediation?
  • Are they certified and experienced in mold remediation?

By ensuring that your chosen company adheres to best practices, you can protect your home and loved ones from the hidden dangers of improper mold remediation.


While the sight of mold can be alarming, it’s crucial to address it properly. Using harmful chemicals to kill mold without removing it can leave behind allergens and toxins that compromise your indoor air quality and health. Always opt for comprehensive mold remediation services that prioritize both elimination and safety. Your home—and your health—deserve nothing less.
