Mold Testing Laws and What Consumers Need To Know

October 25, 2019

Mold Testing Laws: New Hampshire joins several states regulating mold testing by requiring mold inspectors and remediators to be licensed. Additionally, the law states that it is illegal to conduct both the testing and remediation by the same company. IndoorDoctor is one of the very few companies in New England that is licensed and meets the most stringent standards set forth by the American Council for Accredited Certification (ACAC) to perform mold testing.

Before you hire mold testing make sure they are licensed by going to

The ACAC offers independent, accredited certifications to experienced professionals. Council certificate holders have demonstrated their knowledge and experience in such fields as building sciences, industrial hygiene, indoor environmental risk assessment and microbial investigation, remediation and consulting. Council certification programs are the most rigorous in their fields and maintain the highest professional standards.

The ACAC is the only indoor air quality organization whose certifications have achieved CESB accreditation. Council programs employ psychometrically rated examinations that test industry knowledge and also require verified field experience of each certification candidate. Council certifications are board-awarded by a nationwide panel of industry peers for a period of two years, after which each certification candidate must undergo a rigorous re-certification process. CESB accreditation is the latest evidence that ACAC certifications continue to set the standard in the industry for integrity, credibility and independence

These laws are designed to protect the homeowner from an unwanted conflict of interest from companies that do both the mold testing and clean-up work. We encourage homeowners and business owners to consider only hiring independent and licensed companies to perform their indoor environmental testing.

The ACAC has set forth recommended legislation language stating that:

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 from training organizations, membership organizations and industry trade associations.

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


3) Individuals shall not conduct mold or microbial remediation or abatement activities for a period of one year on projects for which they have conducted investigations, or assessments
