Mold growth can be a persistent and concerning issue for homeowners and property owners. When it comes to mold remediation, various methods are available, including mold encapsulation and dry fogging. While mold encapsulation may seem like an attractive option due to its simplicity and non-destructive nature, it’s important to understand its limitations.

In this blog post, we will explore the pros and cons of mold encapsulation as a mold remediation service and discuss why dry fogging may be a better choice, as it addresses the underlying mold problem more effectively.

What is Mold Encapsulation?

Encapsulation involves applying a specialized coating or sealant to mold-infested surfaces. This process encapsulates the mold and prevents it from releasing spores into the air. It is often used when complete removal of the mold is not feasible or as a preventive measure in areas prone to mold growth.

Benefits of Mold Encapsulation

  1. Containment: One of the main advantages of mold encapsulation is that it creates a barrier that seals off the mold growth. It effectively prevents the release of mold spores into the air, reducing the risk of further contamination. Encapsulation helps contain the mold and can be particularly useful in cases where complete removal of affected materials is not feasible or cost-effective.
  2. Preservation of Materials: Encapsulation allows for the preservation of existing materials, such as drywall, wood, or other surfaces. Rather than removing and replacing these materials, encapsulation provides a cost-efficient alternative by encapsulating the mold growth and providing a clean and visually appealing finish.
  3. Aesthetic Improvement: Mold-infested surfaces can be unsightly, and encapsulation offers a solution by improving the appearance of affected areas. The application of a specialized sealant or coating can create a smooth, uniform surface that conceals the presence of mold, making it visually appealing.

Cons of Mold Encapsulation

  1. Limited to Surface Treatment: Mold encapsulation primarily addresses the visible mold growth on surfaces, creating a barrier between the mold and the surrounding environment. However, it does not eliminate the mold problem entirely. Mold can continue to grow and spread behind the encapsulated surface if the underlying cause, such as moisture or water intrusion, is not addressed. This means that encapsulation alone does not provide a comprehensive solution to mold remediation.
  2. Ineffective Against Hidden Mold: Encapsulation may fail to address hidden mold growth within walls, ceilings, or other concealed areas. Without proper identification and removal of hidden mold, encapsulation cannot effectively eliminate the entire mold infestation. This poses a risk of recurring mold problems and potential health hazards for occupants.
  3. Maintenance Challenges: Encapsulated surfaces require regular inspection and maintenance to ensure the integrity of the encapsulant. Over time, the encapsulation may wear off or become damaged, potentially compromising its effectiveness. Maintenance efforts may involve reapplication or repair, adding to the long-term costs and efforts associated with mold remediation.

Why Choose Dry Fogging for Mold Remediation?

Dry fogging, also known as aerosolized fogging, offers several advantages over mold encapsulation, making it a preferred choice for mold remediation.

  1. Comprehensive Treatment: Unlike encapsulation, dry fogging addresses both visible and hidden mold growth. The fine mist generated during dry fogging can penetrate hard-to-reach areas and porous materials, effectively neutralizing mold spores and inhibiting their growth. It offers a more thorough and comprehensive treatment approach.
  2. Source Elimination: Dry fogging tackles the underlying cause of mold growth by targeting moisture-related issues. By controlling humidity, improving ventilation, and addressing water intrusion problems, dry fogging helps eliminate the conditions that facilitate mold development. This proactive approach reduces the chances of recurring mold problems in the future.
  3. Non-Destructive & Time-Efficient: Dry fogging does not require the removal or replacement of materials, resulting in minimal disruption to the property and its occupants. It is a relatively quick process, allowing for faster remediation and a prompt return to a safe and healthy living or working environment.
  4. Prevention of Airborne Contamination: Mold spores can become airborne during remediation activities, potentially causing respiratory issues and spreading mold to unaffected areas. Dry fogging effectively reduces airborne contamination by trapping mold spores and debris, preventing their dispersal into the air.

Pure Maintenance of Central Illinois Dry Fogging Process:

  1. Assessment: A trained professional conducts a thorough inspection of the property to identify areas affected by mold growth and assess the extent of the contamination. This assessment helps determine the appropriate treatment plan.
  2. Preparation: Before initiating the dry fogging process, the affected areas are prepared by removing or covering sensitive items, such as electronics or furniture, to protect them from the fogging solution.
  3. Application: The dry fogging machine, specifically designed by Pure Maintenance, is used to disperse a fine mist of a proprietary solution called InstaPURE. This solution is a non-toxic, EPA-registered, and hospital-grade disinfectant that is effective against mold, bacteria, viruses, and other pathogens.
  4. Penetration & Treatment: The dry fog generated by the machine consists of tiny particles that can penetrate difficult-to-reach areas, including cracks, crevices, and porous materials. The fog envelops the contaminated surfaces, eliminating mold spores and neutralizing other harmful microorganisms.
  5. Dwell Time: The fog is left to dwell for a specific period, allowing the solution to come into contact with and effectively treat the mold and other contaminants. This dwell time ensures thorough disinfection and remediation of the affected areas.
  6. Air Filtration: During the process, an air scrubber with HEPA filtration is typically used to capture any airborne particles, including mold spores, ensuring a cleaner and healthier indoor air quality.
  7. Post-Treatment Assessment: After the dry fogging process is complete, a post-treatment assessment may be conducted to evaluate the success of the remediation and ensure that the mold and contaminants have been effectively eliminated.


While mold encapsulation offers certain benefits such as containment and preservation of materials, it falls short in addressing the underlying mold problem and eliminating hidden mold growth.

Dry fogging, on the other hand, provides a more comprehensive and proactive approach by treating both visible and hidden mold, targeting the source of the problem, and preventing future mold growth.

When considering mold remediation methods and companies, it is crucial to prioritize solutions and services that effectively address the root cause and ensure a long-term mold-free environment.
