Drywall is a standard finishing trade, but silica dust from cutting and sanding creates a real coverage consideration. Here is what to require.
Drywall work sits on the lower end of the construction risk spectrum compared to trades like roofing or concrete, but it is not without coverage considerations. Silica exposure from cutting and sanding creates both a workers' comp loss history and a potential pollution-adjacent exclusion to watch for.
Standard GL and workers' comp are the core requirements. Confirm the class codes cover both hanging and finishing, since the work rates differ, and watch for dust exclusions if cutting is in scope.
Policies to require
Policy
Typical limit
Why it matters
General Liability
$1M per occurrence / $2M aggregate
Covers property damage from dust and debris, third-party injury, and completed operations for finishing defects that require rework.
Workers' Compensation
Statutory limits
Drywall hanging involves awkward lifts, overhead work, and silica dust. Workers' comp is required for any employee.
Commercial Auto
$1M combined single limit
Drywall crews drive to site with vans or trucks loaded with sheet goods.
Umbrella / Excess Liability
$1M (larger projects)
Required on commercial projects or where the GC's contract specifies it.
Typical limits reflect common GC contract requirements as of 2026. Actual requirements vary by contract, project size, owner, and jurisdiction.
What to verify on the COI
When you receive the certificate of insurance from a drywall contractor, check each of the following before approving the document.
Named insured matches the legal entity name in your subcontract
Certificate holder lists your company name and address
Your company is endorsed as additional insured on the GL policy
GL limits meet your contract minimums
Workers' comp class codes cover both drywall hanging and taping/finishing work
No silica dust or dust exclusion in the GL policy if cutting or grinding is in scope
Completed operations is included for finishing defects and rework claims
Common gaps and watch-outs
Silica dust from cutting
Cutting drywall with a saw generates crystalline silica dust. Some GL policies include a dust or pollution exclusion broad enough to bar coverage for silica-related claims. If the project involves significant cutting (openings, furring, custom shapes), verify the GL does not exclude dust-related property damage or bodily injury.
Hanging vs finishing class codes
Drywall hanging and taping/finishing carry different workers' comp class codes and rates. A policy rated only for one may not respond to a claim from the other. Confirm the declarations page covers both if the sub performs the full scope.
Moisture and mold from improper installation
Drywall installed over wet framing or in a location with moisture exposure can develop mold. Some GL policies exclude mold or limit coverage for moisture-related claims. This matters on projects with tight schedules where enclosure happens before framing is fully dry.
Textured ceiling spray (popcorn or knockdown)
Spray texture application creates overspray risk and, on older buildings, may disturb asbestos-containing materials. If the scope involves texture spray on a pre-1980 structure, verify the GL covers it and ask about asbestos disturbance risk.

General liability ($1M/$2M), workers' compensation, and commercial auto. Umbrella is common on commercial projects. Watch for silica or dust exclusions in the GL if cutting is part of the scope.
Does a drywall contractor need pollution liability?
Usually not, unless the scope involves asbestos-containing material (ACM) disturbance on older structures or significant silica dust generation. Standard GL is generally sufficient for new construction drywall work.
What are the silica risks for drywall work?
Cutting drywall with a power tool creates crystalline silica dust. Over time, repeated exposure causes silicosis, a serious lung condition. Workers' comp covers the health claim. The GL question is whether dust-related property damage (contaminated HVAC, finishes) is also covered.
Do small drywall crews need workers' comp?
Yes, in most states, as soon as any employee is on payroll. Even a two-person crew hanging sheets overhead has real injury exposure from awkward lifting and falls from stilts or ladders.
