Data sources

What it is. The Institute of Inspection, Cleaning and Restoration Certification (IICRC) is the leading global standards-setting body for restoration trades. Their Certified Firm Locator is a public, real-time directory of every firm currently certified in disciplines such as Applied Microbial Remediation Technician (AMRT), Applied Microbial Remediation Specialist (AMRS), and Water Damage Restoration.

How we use it. We import every IICRC firm holding a mold-relevant credential (AMRT or AMRS) and tag them with source_name='IICRC' so they can be filtered or removed in bulk if the licensing relationship ever changes.

Refresh cadence. Re-scraped quarterly; on-demand when expiration data lapses.

What it is. The International Association of Certified Home Inspectors (InterNACHI) operates a public certified-inspector directory. We use the subset that holds the Certified Mold Inspector (CMI) credential.

How we use it. Imported list-page records (name, company, city, phone, profile URL). Drilling into individual profile pages for additional fields is not part of the current import.

Refresh cadence. Re-scraped quarterly.

What it is. The American Council for Accredited Certification (ACAC) publishes a public directory of holders for credentials including CIE (Council-certified Indoor Environmentalist), CMC (Council-certified Microbial Consultant), CMR (Council-certified Microbial Remediator), CMRS (Supervisor), and CIEC (Consultant).

How we use it. Filtered to certificants holding any of CRMI, CMI, CMR, CIE, CIEC, CMRS. Tagged with source_name='ACAC' for traceability.

Refresh cadence. Re-scraped quarterly.

What it is. The Texas Department of Licensing and Regulation maintains a public registry of every state-licensed mold assessment company, mold remediation company, mold consultant, and mold technician. We import the COMPANIES (full contact info) and skip individual licensees so the directory shows firms, not people.

How we use it. Direct CSV download (vsMoldRemediationCompany.csv, vsMoldAssessmentCompany.csv). Active-license filter applied. Tagged with source_name='TX TDLR'.

Refresh cadence. Re-scraped weekly.

What it is. The New York State Department of Labor publishes the active list of all mold assessment, mold remediation, and mold abatement contractor licenses through the data.ny.gov Socrata open-data API. Every active license carries the licensee's business name, address, phone, and license number.

How we use it. Pulled live from the Socrata endpoint with status = ACTIVE. Tagged with source_name='NY DOL' and cert label 'NY Mold Assessment Contractor' / 'NY Mold Remediation Contractor' depending on license type.

Refresh cadence. Re-pulled weekly.

What it is. The U.S. EPA maintains a public registry of every firm holding a Renovation, Repair, and Painting (RRP) certification under the federal Lead-Safe Certified Firm program. RRP firms are credentialed for LEAD-PAINT hazard work, not mold -- but cross-discipline overlap with mold contractors is common.

How we use it. We do NOT auto-create mold listings from EPA Lead-Safe data. Instead, we cross-reference the registry against firms we already have via our mold-specific sources. When a firm matches by phone or by normalized name + state, we append the 'EPA Lead-Safe Certified Firm (RRP)' credential to their existing listing. This adds a real, verifiable credential without polluting the directory with non-mold contractors.

Refresh cadence. Re-pulled quarterly.
