Why Choose Certified Indoor Air?

Some states require licensing and uphold specific standards regarding mold inspection, testing, and remediation. Unfortunately, North Carolina is not one of these states. The ACAC is an organization that seeks to standardize the industry and ensure that those providing these services have the knowledge and experience to do the job right. Certified Indoor Air is one of the few mold inspection companies in North Carolina that is certified and meets the stringent standards set forth by the ACAC, including rigorous testing and continuing education coursework to maintain certification.

While it is already illegal in many states, the ACAC has recommended national legislation to protect homeowners from the conflict of interest arising from companies performing mold testing and mold remediation services.

1) Mold testing and microbial investigation, assessment, remediation, abatement, and consulting services shall be performed by individuals who are certified by the American Council for Accredited Certification (ACAC) or another national, non-profit certifying body which:

a) is accredited by the Council of Engineering and Scientific Specialty Boards (CESB) and/or the American National Standards Institute under ANSI/ISO/IEC 17024, and

b) is wholly independent of training organizations, membership organizations, and industry trade associations.

2) Individuals shall not conduct mold or microbial investigations, assessments, or consultations for one year on projects for which they have conducted remediation or abatement services.

3) Individuals shall not conduct mold or microbial remediation or abatement activities for one year on projects for which they have completed investigations or assessments.
