Our Process

  1. 1

    Inspection and Assessment

    Our technicians conduct a thorough inspection to assess mold growth and locate moisture sources. Using advanced tools like moisture meters, we develop a remediation plan tailored to each property's specific needs.

  2. 2

    Quality Containment Setup

    We set up containment using 6-mil plastic sheeting and create negative air pressure to prevent spore spread. This ensures the mold is confined to its local area and does not contaminate clean spaces.

  3. 3

    Effective Mold Removal

    Through a process including HEPA vacuuming and controlled demolition, our team carefully removes mold-infested materials, bagging and sealing waste for safe disposal.

  4. 4

    Antimicrobial Treatments

    After visible mold removal, we apply EPA-approved antimicrobial agents to surfaces and use HEPA-filtered air scrubbers to further purify the indoor air, mitigating any residual mold spores.

  5. 5

    Clearance Testing

    The remediation concludes with third-party clearance testing to verify all mold has been successfully eradicated, ensuring your home is safe and meets industry standards.
