Commercial & Industrial Electrical Services

Industries We Serve Across the Charleston Region

Charleston's commercial economy is diverse: hospitality on the peninsula, manufacturing along the I-26 corridor, healthcare in West Ashley and Mount Pleasant, retail in Summerville and Goose Creek, and a rapidly expanding logistics footprint near the port and inland terminal. Each of these sectors brings unique electrical requirements, and our team has spent years learning the codes, the inspectors, and the operational constraints that come with each.

We work on hotels, restaurants, medical and dental offices, retail stores, warehouses, light manufacturing facilities, churches, professional offices, multi-tenant buildings, and quick-service restaurants. We hold the licenses and insurance required by every Charleston-area municipality and we pull permits in our own name.

Three-Phase, Generator, and Standby Systems

Most commercial buildings in the Lowcountry run on 208Y/120V or 480Y/277V three-phase service, and many require a permanent standby generator with an automatic transfer switch for life safety, optional standby, or full building backup. We install, service, and load-test generators from Generac, Kohler, Cummins, and Caterpillar, and we coordinate with utility, fire marshal, and any required commissioning agents.

• Service entrance upgrades up to 4000A
• Three-phase motor controls and starters
• Generator and ATS installation, commissioning, and testing
• Tenant build-out and white-box electrical
• After-hours and weekend service to avoid downtime
• Preventive maintenance contracts and IR scans
• 24/7 emergency commercial response

Why Charleston Businesses Choose EmergenServe

We answer the phone, we show up when we say we will, and we communicate clearly about scope and pricing. Our project managers attend coordination meetings, our field crews arrive in marked trucks with the proper PPE, and our administrators handle the certificates of insurance, lien waivers, and AIA billing your property manager or general contractor expects.

For property managers responsible for a portfolio of Charleston-area buildings, we offer master service agreements and consistent on-call response. For business owners, we offer transparent pricing and flexible scheduling that minimizes downtime.

How We Schedule Around Your Operating Hours

Commercial electrical work that shuts down a kitchen, a sales floor, or a clinic costs you a lot more than the labor on our invoice. We schedule around that. For King Street restaurants we show up at 11 p.m. when the last cover walks out, swap the hood-control panel or the failed contactor, and have you ready for prep cooks at 9 a.m. For West Ashley medical offices we plan panel upgrades for Saturday morning, coordinate the Dominion Energy disconnect window in advance, and have the IT closet UPS-backed before we ever pull the meter so your servers and DICOM workstations never go cold.

We carry commercial-grade parts on every truck, Square D I-Line breakers in common frame sizes, three-phase contactors from 30 to 200 amps, definite-purpose contactors for HVAC, motor-rated disconnects, and replacement Generac and Kohler ATS controllers for the standby systems we maintain across the Lowcountry. We send a single foreman who owns your project from kickoff to final inspection, and we provide the certificates of insurance, lien waivers, and AIA G702/G703 billing your property manager already knows how to process.
