Posted by: Core Team, Inc. on December 1, 2023

Mold, a common household nuisance, can wreak havoc on your living space, affecting both the structural integrity of your home and the health of its occupants. Preventing mold growth requires a combination of proactive measures, awareness, and regular maintenance. In this comprehensive blog post, we will explore effective strategies and tips to keep mold at bay and maintain a healthy living environment.

Understanding the Basics of Mold

Before delving into prevention strategies, it's essential to understand what mold is and how it thrives. Mold is a type of fungus that grows in damp and humid environments. It reproduces through tiny spores that float through the air, seeking suitable conditions to settle and grow. Mold can thrive on various surfaces, including walls, ceilings, carpets, and even household items.

1. Maintain Optimal Indoor Humidity

Problem: High indoor humidity is a prime breeding ground for mold.


Use Dehumidifiers: Invest in a dehumidifier to regulate indoor humidity levels. Aim for a relative humidity of 30-50%, as this range is inhospitable for mold growth.

Frequently Asked Questions

For the majority of surfaces in your home, bleach won’t actually get rid of your mold problem. It’s the “iceberg effect.” Visible mold is usually a small percentage of the actual amount of mold growth. Bleach can’t kill mold on porous surfaces like wood, and while tile or fiberglass surfaces can be cleaned with bleach, often the mold has spread far deeper. The reason why mold remediation companies don’t recommend DIY cleanup isn’t that they want to make more money; they know, in their experience, that a mold problem is usually far more invasive than can be seen with the naked eye. Simply cleaning the surfaces can provide false assurances that you got rid of the mold, only to have it come back time and time again.

Sometimes mold remediation is included if the cause of the mold was a “covered peril” like a burst hot water heater or water damage caused by firefighters extinguishing a fire in your house. Gradual water damage - like from a leaking pipe or hose - will often cause mold growth, but your insurance coverage will usually not cover that by claiming that it was caused by poor maintenance or neglect. If your insurance company denies your claim, you should request an inspection from a mold remediation company that can help you document the source of the mold.

If the inspection/assessment process was able to pinpoint the source and cause of the mold growth, once that source is repaired, you can be relatively confident about the success of remediation. Ask if your restoration technician has the IICRC certification for “Applied Microbial Remediation.” You can also request a “post-remediation mold clearance” from a third-party mold inspector to re-test the area for any remaining traces of mold before the area is treated with a sealer or encapsulant to resist future mold growth.

    • Cost Range: $5,000 to $30,000 or more
    • Extensive mold growth affecting larger areas, potentially involving structural elements.

DIY vs. Professional Remediation

While some minor mold issues may be addressed with DIY methods, professional remediation is recommended for larger or more complex cases. Professionals have the expertise, equipment, and safety measures to handle mold remediation and prevent future growth effectively.

It's crucial to contact a professional mold remediation company, like CORE TEAM Inc, promptly to assess the situation and provide an accurate estimate based on the unique circumstances of the mold growth. Swift action can also help minimize the overall remediation costs and prevent further damage.

It could be. Because mold spores are microscopic and airborne, you’ll end up breathing them into your lungs. Depending on the type of mold and how well your immune system functions, you may develop some serious health symptoms that could end up being the result of mold. That’s why a mold remediation company takes mold removal so seriously. The space affected by mold is isolated and contained during cleaning so the spores won’t spread to other areas of the house, and the remediation team stays suited up in Personal Protective Equipment (PPE) during the process.

Anytime the moisture levels in your home are at 60% or higher, mold can grow. What’s frustrating for many property owners is that they don’t see a puddle on the floor or water dripping from the ceiling. When mold grows, the source of the moisture is usually hidden under floorboards or behind walls.

Mold remediation is a comprehensive process aimed at removing and preventing the recurrence of mold growth in indoor environments. Mold, a type of fungus, thrives in damp and humid conditions and can pose serious health risks while compromising the integrity of structures. Mold remediation involves the identification, containment, removal, and prevention of mold to ensure a safe and healthy living or working space.

Mold remediation is required when the presence of mold is identified in a property, and its growth poses potential health risks, compromises the structural integrity, or creates an unsanitary living or working environment. Here are common situations in which mold remediation may be necessary:

  1. Visible mold growth
  2. Water damage
  3. Must odor
  4. Health concerns
  5. Visible signs of water intrusion
  6. Property transactions
  7. Building renovations or demolitions
  8. Hidden mold
  9. HVAC contamination
  10. Insurance requirements
  11. Legal or regulatory compliance
  12. Tenant complaints

Mold remediation is essential when mold is identified in indoor environments to protect the health of occupants, maintain structural integrity, and ensure a safe living or working space. Professional remediation services from CORE TEAM Inc are often enlisted to address mold issues comprehensively and effectively.

The responsibility for paying for mold remediation can vary based on several factors, including the cause of the mold, the insurance coverage, and the property ownership. Here are key considerations:

Homeowner's Insurance

Covered Causes

If mold is a result of a covered peril listed in the homeowner's insurance policy (such as water damage from a burst pipe), insurance may cover the cost of mold remediation.


Insurance policies may have exclusions for certain types of mold or mold caused by specific conditions (e.g., long-term neglect or lack of maintenance). In such cases, coverage for mold remediation may be limited.

Policy Terms

It's essential to review the terms of the homeowner's insurance policy to understand the specific conditions under which mold remediation is covered.

Rental Properties

Landlord Responsibility

In rental properties, landlords are typically responsible for addressing and paying for mold remediation, especially if it results from structural issues, leaks, or other property-related problems.

Tenant Negligence

If mold is caused by the tenant's actions or negligence (e.g., failing to report leaks promptly), the responsibility for remediation may shift to the tenant.

Property Ownership

Homeowner Responsibility

Homeowners are generally responsible for addressing mold issues in their homes, whether through DIY methods or by hiring professional remediation services.

Condominiums and Homeowners Associations (HOAs)

Responsibility for mold remediation in shared spaces, such as condominiums or properties governed by HOAs, may be determined by the association's bylaws and policies.

Prevention and Maintenance

Neglect and Maintenance

If mold growth is a result of neglect or lack of maintenance, the responsibility for remediation may fall on the property owner.

Personal Liability

Tenant Liability

In rental properties, if a tenant's actions contribute to mold growth (e.g., improper ventilation or failure to report leaks), the tenant may be held liable for remediation costs.

It's crucial to review insurance policies thoroughly, understand property ownership agreements, and take preventive measures to minimize the risk of mold-related issues. In case of mold growth, consulting with insurance providers and professional remediation services like CORE TEAM Inc can provide clarity on the financial responsibility for the remediation process.
