Construction Trades Insurance FAQ

A GC's exposure is largely contractual and vicarious — courts and contracts routinely hold the general contractor responsible for the overall jobsite even on work performed entirely by subs. That typically means higher GL limits than a single-trade sub would carry (contracts often specify $1M/$2M or more), umbrella coverage as a near-standard contract requirement, and bonding capacity for public or commercial bids, on top of workers' comp scoped only to direct employees.

General liability covers property damage and bodily injury from the physical work — a fire caused by faulty wiring, for example. But design-build, panel design, or low-voltage/security-system work introduces a different question: was the design or spec itself wrong? That's a professional-liability exposure GL doesn't reach, so electricians doing any design-build or systems work typically need E&O alongside GL, not instead of it.

The defining plumbing claim isn't an on-the-job accident — it's a joint or connection that fails months or years after the work is done, and the resulting water or mold damage claim often dwarfs the original job cost. That's a completed-operations claim, not a general liability claim in the everyday sense, which is why plumbing GL policies are underwritten with particular attention to completed-ops wording and limits.

Roofing carries the highest fall-injury severity of the trades on this site, and that shows up directly in market access, not just price — many standard carriers restrict or decline roofing GL entirely, pushing much of the trade into specialty/E&S markets. Policies also need close attention to steep-slope exclusions, subcontracted-labor exclusions, and wind/hail sublimits, which are less common concerns for trades working at ground level.

Refrigerant handling creates an environmental exposure that standard general liability often doesn't cover well, since it's closer to an EPA-adjacent release question than a typical property-damage claim. Most HVAC contractors doing installation or service work — not just large commercial system work — carry pollution liability specifically for refrigerant release and handling, alongside GL and workers' comp.

Excavation's signature exposure is underground — utility strikes, trenching cave-ins, and damage to third-party underground infrastructure that a standard GL policy may limit or exclude without explicit XCU (explosion, collapse, underground property damage) coverage confirmed. Framing crews face height and power-tool risk instead, so their coverage combination centers on workers' comp and builders risk during the framing stage rather than underground exposure.

Generally yes on larger structural pours, since builders risk protects the project itself — materials, forms, and work in progress — during construction, which matters more on foundation and structural work than on smaller flatwork jobs like driveways or slabs. The bigger and more structural the pour, the more builders risk becomes a standard part of the coverage combination rather than an optional add-on.

A license bond is typically required by a state or municipality just to hold a contractor license and protects the public against licensing-law violations. A bid bond guarantees that a contractor who wins a bid will actually sign the contract at the bid price. A performance bond guarantees the contracted work will actually be completed according to the contract terms — GCs and contractors bidding public or commercial work often need more than one of these simultaneously.

For an existing policyholder, COI requests are typically turned around same-day during business hours, since the certificate is just documentation of coverage already in force. New coverage takes longer to bind before a certificate can be issued, which is worth planning for if you need to show proof of insurance to get onto a jobsite on a tight timeline.

Additional insured status extends a portion of a subcontractor's own liability coverage to protect the GC (or other party named) if a claim arises from the sub's work. GCs require it because they carry vicarious liability for the whole jobsite regardless of which trade actually caused the damage, so an additional-insured endorsement on each sub's policy is one of the main ways a GC manages that transferred risk without having to insure every sub's work directly.

Frequently, yes. Insurance and bonds cover different things — insurance protects against liability and loss, while a bond guarantees performance or licensing compliance — and public-sector and larger commercial projects routinely require both. GCs bidding this kind of work in particular should expect bid and performance bonds layered on top of standard GL, workers' comp, and umbrella coverage.

Common requirements include minimum GL limits (often $1M per occurrence / $2M aggregate), an additional-insured endorsement naming the GC, workers' comp for the sub's own employees, and sometimes minimum auto liability limits if the sub uses vehicles on-site. Requirements vary by project size and GC, but a sub that can't produce a compliant COI on request is a common reason work gets held up before it starts.

No — additional-insured status on a sub's policy is narrower than your own coverage. It generally only responds to claims arising from that specific sub's work, doesn't protect you against claims tied to your own operations or other subs, and can be affected by the sub's policy limits, exclusions, or lapses that you don't control. It's a supplement to your own coverage, not a substitute for carrying your own GL and other required lines.
