GL vs. Pollution
Standard GL covers the mechanical side of drywall work — but airborne sanding dust sometimes falls into a gap most contractors don't know exists until a claim tests it.
Most drywall contractors assume their general liability policy covers anything connected to the job, including the fine dust that comes off sanding joint compound. It's a reasonable assumption, and it's not always correct — depending on the carrier and the specific policy language, dust and airborne particulate exposure claims can bump against the pollution exclusion that's standard in most GL policies.
GL continues to respond to the mechanical side of your work regardless of dust exposure questions — a lift damaging a client's floor, a tool causing property damage, an injury from staged materials. See our GL page for the full breakdown. The gray area specifically involves airborne dust and particulate exposure claims.
Sanding joint compound generates fine dust that can settle throughout a building, infiltrate HVAC systems, or trigger respiratory complaints from occupants nearby — particularly relevant on occupied renovation jobs or multi-unit buildings where sanding on one unit can affect neighboring spaces. Some carriers treat this as a pollution-adjacent exposure that standard GL doesn't clearly address.
Some carriers offer a specific endorsement addressing dust and particulate exposure for drywall and finishing operations, closing the gap between standard GL and the pollution exclusion. This is priced separately and worth asking about directly if you regularly work in occupied buildings or multi-unit properties rather than assuming your existing policy already covers it.
A hanger who rarely does finishing work has limited exposure here, since the dust-generating sanding step isn't part of their scope. A finishing contractor doing regular sanding in occupied residential remodels or multi-unit commercial buildings has real exposure that standard GL alone may not fully address.
Tell us how much of your business involves finishing and sanding versus hanging alone, and whether you regularly work in occupied or multi-unit buildings. Our agents will confirm whether your GL is sufficient or whether this additional coverage makes sense.

FAQ
It depends on the carrier and specific policy language — some GL policies carry a pollution exclusion that can apply to dust and particulate claims, which is worth confirming directly rather than assuming.
It's most relevant on occupied buildings and multi-unit properties where dust can affect people or spaces beyond the immediate job site — new, unoccupied construction generally carries less of this specific exposure.
They address completely different things — tools and equipment coverage protects your gear, while this question is about third-party exposure claims tied to airborne dust from sanding operations.
It's less commonly a blanket requirement than standard GL, but it can come up specifically for finishing work in occupied multi-unit buildings — worth having the conversation with your agent proactively.
