Mold Remediation Contractor Insurance

Why standard GL is not enough

Most contractor general liability policies exclude mold, fungi and bacteria, and many exclude pollution. A mold remediation contractor needs coverage built for the work: contractors pollution liability (CPL) that specifically includes mold, usually alongside a GL policy.

Who needs this coverage

Mold remediation companies, water damage restoration contractors, general contractors who remove mold during remodels, industrial hygienists who test and write protocols, and property-maintenance companies that clean mold for landlords or HOAs. If any part of your work touches visible mold, ask how your policy treats it.

Coverage mold contractors carry

• Contractors pollution liability — cleanup and third-party claims from spreading mold or contaminants.
• General liability — ordinary injury and property damage.
• Professional liability — if you also test, assess or write remediation protocols.
• Workers' comp — respiratory and chemical exposure for employees.
• Commercial auto and equipment — air scrubbers, negative air machines, dehumidifiers.

Common claims

• Cross-contamination: mold spreads to unaffected rooms during removal
• A tenant or homeowner claims illness after the job
• Clearance testing later shows mold remained
• Water damage from drying equipment or removed materials
• Employee respiratory exposure

Occurrence vs. claims-made

Contractors pollution liability is written either on an occurrence basis or claims-made. Claims-made policies need continuous coverage and a tail when you stop, because mold claims often surface long after the work. Check the retroactive date on any claims-made policy.

Limits matter too. Property managers and commercial owners commonly require $1 million of pollution liability that names them as additional insured, and larger remediation projects may call for more. Keep your written scope, containment photos, air-scrubber logs and third-party clearance results for every job — they are the best defense if a claim arrives months later.

What underwriters ask

• Remediation only, or assessment and testing too
• Residential vs. commercial
• Written containment and clearance procedures
• Water damage restoration and demolition work
• Certifications and training

Frequently asked questions

Does my GL policy cover mold claims?

Usually not — most GL policies exclude mold. Contractors pollution liability with mold coverage is the usual solution.

Do I need professional liability for mold testing?

If you assess, test or design remediation plans, professional liability covers errors in that advice.

Is mold covered for water damage restoration contractors?

Not by default. Restoration contractors generally need pollution coverage that expressly includes mold.

What limits do property managers require for mold work?

Commonly $1 million, sometimes more, with the manager or owner as additional insured.
