From underground OSP in Charleston's tech corridors to outside plant work across rural BEAD territories — we cover South Carolina fiber contractors everywhere they work.
Required by every South Carolina ISP and GC you’ll sub for. AT&T, Spectrum, and commercial GCs across Charleston and Columbia require proof of GL — with additional insured endorsements — before a subcontractor starts South Carolina fiber work.
South Carolina requires workers' compensation coverage for employers with employees — and every major prime working in the state requires it on your COI regardless of statutory minimums. It protects crews doing aerial work, underground OSP, and inside-plant installs across Charleston, Columbia, and rural South Carolina.
Covers work trucks, bucket trucks, and splice trailers hauling equipment between Charleston, Columbia, and job sites across South Carolina. Long crew-travel distances make commercial auto with hired & non-owned coverage critical.
South Carolina municipalities, AT&T, and DOT right-of-way contracts require $2M–$5M umbrella for public infrastructure fiber contracts. Charleston Metro broadband contracts are requiring higher limits.
Protects fusion splicers, OTDRs, cable reels, and boring equipment whether at a South Carolina job site, in transit, or stored at your Charleston-area yard. Weather and theft coverage included.

South Carolina Department of Labor, Licensing and Regulation (SC LLR) — Burglar Alarm Tier I/II for low voltage. Primes verify both licensing and insurance during Avetta / ISNetworld onboarding — get either wrong and the PO stalls.
The four claim types that hit fiber and low voltage crews most often — and the coverage line that responds to each.
A directional bore or trench clips a gas, water, or electric line. The most expensive claim class in fiber construction — evacuation, utility repair, and third-party damages stack fast. GL responds, but only if your policy carries no XCU exclusion (CG 21 42). We verify before binding.
Your crew damages a live line on a joint pole or shared duct bank, and the owner bills repair plus service-interruption damages. GL property damage responds — watch for “care, custody, or control” pushback on the strand you were hired to work.
A bucket truck rear-ends traffic near a Charleston work zone, or a towed drill rig fishtails on the highway. Commercial auto responds — a trailered rig follows the power unit’s liability, while physical damage on the rig itself is an inland marine claim.
Falls from aerial work, trench cave-ins, strain injuries on cable pulls. Workers’ comp pays medical and lost wages — and your class code (7600 vs. 6325) drives the premium, so misclassification costs real money at audit.
Generic agents don’t understand fiber work. We know South Carolina’s licensing landscape, prime contractor COI requirements, and the risks of aerial and underground work across Charleston, Columbia, and all of South Carolina.
We track the rules that apply to your scope — South Carolina Department of Labor, Licensing and Regulation (SC LLR) — Burglar Alarm Tier I/II for low voltage — and make sure your policy and COIs line up with what your license class and your primes require.
South Carolina's fiber market spans Charleston's port and hospitality corridor, Columbia's government/university markets, Greenville's Upstate manufacturing, and Rock Hill's Charlotte-metro spillover; SC LLR Tier I/II licensing is the compliance gate. We know which primes are hiring subs and what their insurance minimums look like.
Primes like AT&T and Spectrum won’t release a PO without a compliant COI. We issue certificates with the right additional insured endorsements the same day you’re bound.
Standard policies often exclude underground telecom work. We make sure your South Carolina policy covers your actual scope — boring, trenching, aerial, and splicing included.
