Is Mold Removal Licensed in District of Columbia?
Yes — Washington D.C. has required mold remediation licensing since 2016.
Washington D.C. has required mold remediation contractors to be licensed by the DC Department of Energy and Environment (DOEE) since 2016. The DC licensing framework requires contractors to pass an ACAC (American Council for Accredited Certification) examination and maintain active certification. The contractor/inspector split is an important protection in DC — the company performing the remediation should not be the same entity performing the post-remediation clearance test. DC's older housing stock and basement moisture issues make mold remediation a common need, and the licensing requirement gives homeowners meaningful legal recourse.
How to Verify a District of Columbia Mold Contractor
Verify DC mold contractor credentials through the DC Department of Energy and Environment. Ask any contractor for their DC license number and ACAC certification. DC homeowners can file complaints with the DOEE if a licensed contractor performs substandard or fraudulent work.

A valid District of Columbia license is the starting point — not the complete picture. Licensed contractors can still perform substandard work or engage in predatory practices. Here is what to verify in addition to license status:
IICRC Certification
The industry standard certification for mold remediation. Verify directly at iicrc.org/certified-firm-search. Ask for the certification number — not just a claim.
Separate assessment and remediation
The company doing the mold removal should never be the same company doing the testing or the clearance test. This conflict of interest is the most common source of inflated scopes and unnecessary work.
Written, itemized estimate
Square footage of containment, materials to be removed, equipment, timeline, and payment terms — all in writing before work starts. Verbal quotes are not contracts.
Independent clearance test
The final step of any legitimate mold removal job is a clearance test by an inspector with no financial connection to the removal company. This is the only way to verify the job was done correctly.
Liability insurance
Ask for a certificate of insurance before work begins. Uninsured contractors leave you exposed if something goes wrong during the job.
The Most Common Mold Scam in District of Columbia
Regardless of licensing status, the most documented mold scam in every market works the same way: a company offers a free inspection, identifies alarming amounts of “toxic black mold,” and pushes for an immediate contract. The same company does the testing, the removal, and the clearance — eliminating any independent check on their findings or their work.
In District of Columbia, a licensed contractor engaging in this practice may be violating state law in addition to committing fraud. Report suspected violations to the relevant licensing authority.
