When the claim is that the work did not hold up, GL does not answer.
A failed mold clearance. A drying job that did not meet the standard. A decontamination a client says was incomplete. None of those is a slip and fall or accidental damage, so general liability does not respond. They are claims about the quality and completeness of your work, and professional liability is the coverage built for them. On mold and biohazard work especially, the disputed-result claim is one of the most common, which is why this line belongs on the program. We are independent, so we make sure it is there.

General liability answers for bodily injury and property damage, not for the performance of your work, so a failed clearance or a disputed remediation falls outside it entirely. That gap is why professional liability sits alongside general liability on most serious restoration programs rather than in place of it.
Two different questions, two different coverages
General liability answers one question: did your work injure someone or damage their property by accident. Professional liability answers a different one: did your work meet the standard it was supposed to. Restoration produces both kinds of claim, and they are not interchangeable. A crew that damages a floor is a general liability matter. A remediation the client says did not work is a professional one, and only professional liability responds to it.
The claims it actually responds to
The professional claims restoration sees are specific: a post-remediation verification that fails, a mold recurrence blamed on your work, moisture missed behind a wall, a drying standard not met, a scope or estimate error, a decontamination a client or health authority calls incomplete, and testing or consulting mistakes if you offer those services. What they share is a dispute about the quality or completeness of the work, which is exactly the territory general liability is written to exclude.
What it costs, and what moves the number
Professional liability is priced off revenue, the services you offer, the share of high-dispute work like mold and biohazard, and loss history, not a flat rate. It is added as its own line on the program, and firms that offer assessment, testing, or consulting alongside remediation carry more exposure and price higher than pure labor operations. We size the limit to the work you do and quote it against your actual operation rather than a template.
Claims-made, continuity, and retroactive dates
Professional liability is usually written claims-made, which means the policy must be in force when a claim is made, not just when the work was done. That makes the retroactive date and continuity between policies critical, because a lapse can leave years of past work uncovered. If you wind down or switch carriers, tail coverage protects that history. We manage the retroactive date and the tail so a coverage change does not open a hole under your completed work.
Assessors, consultants, and Oregon standards
We are based in Eugene, so Oregon is where we start. Oregon does not license mold or restoration consulting separately, but if you provide assessment, moisture consulting, or written protocols, you are giving professional advice others rely on, which broadens the exposure. Some states require assessment and remediation to be separate parties. We match the professional coverage to the advisory services you actually offer, and your state page has the local detail.
Questions worth asking before you sign
Ask whether professional liability is on your program at all, since many restoration contractors carry only general liability. Ask what the retroactive date is and whether there is a gap in your history. Ask whether it covers assessment and consulting if you offer them. Ask whether it meets the certificate requirements for your mold and biohazard work. If the only coverage is general liability, the disputed-result claims have nowhere to land.
Coverages this work needs
The lines that make up a professional liability program. Each has its own page with what it does, how it applies, and where the gaps hide.
General Liability
Answers for bodily injury and property damage. It does not answer for the quality of your work, which is the gap this fills.
General liability →Mold Remediation
Where failed clearances and disputed verifications make this coverage essential.
Mold remediation →Contractors Pollution Liability
Covers the contamination. Professional liability covers the disputed result of cleaning it up.
Pollution liability →Care, Custody & Control
For physical damage to property in your care, a different exposure from a disputed outcome.
Care, custody & control →Water Damage Restoration
Drying-standard and moisture-mapping disputes land on professional liability.
Water restoration →Biohazard & Trauma Cleanup
Disputed decontamination is a professional claim, not a general liability one.
Biohazard cleanup →Restoration insurance by state
Mold licensing, the EPA lead rule, and construction licensing change at the state line. Pick yours for the local rules and what we can place there.
