FAQs

  • What is mold remediation?

    Remediation is the process of cleaning or removing damaged building materials and restoring a property to its original condition following mold infestation. The remediation process starts with an inspection to assess the damage and identify the type of mold. Mold remediation companies use specialized methods to contain the damage, remove residual moisture, and capture airborne spores. Depending on the extent of the damage, professionals may sanitize or remove affected materials. Projects may also involve extensive structural repairs.

  • How much does mold remediation cost?

    The average cost of mold remediation ranges from $500 for isolated infestations to upwards of $10,000 for building-wide contamination. Remediation companies use a variety of costly equipment, including HEPA vacuums and negative air machines. Rates may also include structural repairs and laboratory tests. Limited restoration projects, such as remediating air ducts, attics, walls, or crawl spaces, typically cost around $4,000.

  • What happens during mold remediation?

    Mold remediation is a complex multi-step process that involves removing contaminated materials, containing the damage, and restoring the property to its original condition. First, workers will assess the infestation to determine the best course of action. Because mold is typically caused by excess humidity, stopping leaks and removing residual moisture are critical steps. Workers use specialized equipment, including hazmat suits, respirators, and negative air machines, to protect themselves and prevent cross contamination. Next, they will remove contaminated materials, collect items for off-site restoration, and use EPA-registered biocides or encapsulating agents to sanitize non-porous surfaces and prevent additional mold growth.

  • Can you do your own mold remediation?

    Homeowners can undertake mold remediation procedures in some situations. DIY techniques are most effective when contamination is caught quickly, affects less than 10 square feet, and involves non-porous surfaces. There are also some very good reasons not to perform this work independently, including the risk of cross contamination. Mold spores can stick to clothing even after washing, and construction work can lead to an increase in airborne contamination. Additionally, mold remediation professionals have access to specialized equipment and protective gear to ensure optimal results.

  • Can you remediate mold on drywall?

    Remediating moldy drywall involves removing and replacing the affected material. Unfortunately, drywall cannot be cleaned because mold spores can grow inside the pores of the surface. There's also a good chance that the insulation and wall studs will be infected. Care must be taken when removing the damaged material to contain the mold spores and prevent secondary contamination.

  • How do you remediate black mold?

    Black mold infestations related to Stachybotrys chartarum are common following water damage. This toxic mold species typically colonizes cellulose, fiberboard, and drywall, and significant infestations should be handled by a mold remediation professional.

  • Does home insurance cover mold remediation?

    It depends. Mold growth caused by maintenance-related issues, including faulty gutters, hidden plumbing leaks, or aging roofing shingles, typically won't be covered. On the other hand, insurers generally approve claims for mold remediation related to catastrophic events, such as storm damage, fallen trees, vandalism, and frozen pipes. The answer usually depends on whether the problem was preventable and whether the incident involved flooding or a named exclusion.
