Generators Contractors in Charleston, South Carolina
Standby and portable generator installation and service..
Charleston is a historic coastal city with specialized masonry and hurricane-resistant contractor demand.
Whole-home standby generators automatically provide backup power during outages, protecting against food spoilage, frozen pipes, sump pump failure, and loss of medical equipment. Natural gas or propane-fueled standby generators (typically 12–24 kW for residential use) start within seconds of a power outage via an automatic transfer switch. Installation involves an electrical subpanel or whole-house transfer switch, a concrete pad, gas line connection, and compliance with setback and noise ordinances. Portable generators serve as a lower-cost option for partial backup but require manual setup and fuel management.

- ✓Confirm the estimate includes the transfer switch, concrete pad, gas line, and all permits.
