Who Can Remediate Mold in Maryland?

Local Mold Remediation Standards in Maryland

Maryland's Department of Health and Environmental Services requires mold remediators to follow the National Institute of Building Sciences (NIBS) Mold Remediation Standard and to be certified by a recognized body such as the Institute of Inspection, Cleaning & Restoration Certification (IICRC). Contractors must also hold a valid Maryland business license and maintain liability insurance covering mold work.

Types of Professionals Qualified to Remove Mold

Qualified mold remediation in Maryland falls into three main categories:

• Certified Remediation Companies – Firms that hold IICRC or NIBS certification and provide full site assessments, containment, and post‑remediation air testing.
• Licensed HVAC Technicians – Technicians with HVAC credentials who can address mold growth in ducts, often certified in mold sampling and decontamination.
• Building Inspectors and Environmental Engineers – Professionals who conduct detailed inspections, identify mold sources, and recommend remediation plans, though they may subcontract the removal.

Key Credentials and Documentation to Verify

When selecting a contractor, verify:

• Current IICRC or NIBS certification certificate.
• Maryland state business license and insurance certificates.
• Evidence of completed mold remediation projects, including before/after photos and air quality test results.
