Coverage for Masonry Subs: What You Need to Carry as the 1099

Being a Sub Doesn't Mean You're Off the Hook

If you're brought onto a job as a subcontractor rather than holding the prime contract, it's easy to assume the GC's or lead mason's insurance covers you. It doesn't. Their policy protects their business from claims arising from the overall project — it's not a substitute for your own coverage on the work you personally perform. Whoever hired you is looking out for their own exposure, not yours, and their certificate requirements exist specifically because your coverage is a separate question from theirs.

What the Mason or GC Hiring You Will Ask to See

Before you're allowed on site, most GCs and lead masons will ask for a certificate of insurance naming them as additional insured, proof of workers comp if you have employees, and sometimes a signed waiver of subrogation. This isn't optional paperwork — on larger jobs, you often can't mobilize without it already on file, and a mid-week delay waiting on a certificate can cost you the job entirely if another sub is ready to step in.

Your Own GL Doesn't Disappear Because You're a Sub

Whatever masonry work you personally perform still needs to be covered by your own general liability policy, sized to the jobs you're actually taking on. A sub working under a larger contractor still needs limits that satisfy that contractor's own insurance requirements, which are often set higher than what a solo residential mason would carry working directly for homeowners. Don't assume your existing policy automatically clears whatever bar a new GC sets — check their specific limit requirement before you commit to the job.

Additional Insured Status Cuts Both Ways

Naming the hiring party as additional insured on your policy protects them from claims arising out of your work — but it doesn't reduce your own exposure. You're still the one whose policy responds first if your masonry work is the cause of a claim, regardless of who else is named on the certificate. It's worth understanding this distinction clearly, since some subs mistakenly believe additional insured language somehow shifts risk away from them rather than simply extending protection outward.

Certificates You'll Be Asked to Produce Repeatedly

If you regularly work as a sub for multiple masons or GCs, you'll likely be asked for a fresh certificate on every new job, sometimes with different additional insured language each time. A policy structured correctly from the start makes turning those around quickly a non-issue instead of a scramble before every mobilization. A blanket additional insured endorsement in particular means you're not calling your agent every time you pick up a new job.

What Coverage Typically Costs for a Working Sub

Pricing for a subcontractor's GL policy generally follows the same drivers as any working mason — revenue, structural versus veneer work, and whether you carry employees — but the limits you need are often set by whoever's hiring you rather than by your own preference. See our cost breakdown for what GL typically runs, and confirm the specific limit a prospective GC requires before you price it out.

Getting Set Up Before You Take the Job

The worst time to discover your coverage doesn't meet a hiring contractor's requirements is the week you're supposed to start. Get your policy in place before you're bidding sub work rather than after you've already won it, so producing a certificate is a same-day formality instead of a delay that costs you the job.
