Residential electrical services
GPM Electrical handles the electrical work that keeps Greeneville homes running: new panels, power for mobile homes, tripping breakers, a dead outlet in the kitchen, a generator hookup before storm season. It is a two-person local business, and Nick Foster is the electrician you talk to on the phone and the one who shows up. Every service below is residential work, and small jobs are welcome.

A second look at the panel, wiring and outlets before you buy or after problems.
Learn moreThe panel is the heart of the house, and older ones wear out. We replace breaker boxes, convert screw-in fuse panels to breakers, and fix the problems that show up at the main. Start with our electrical panel upgrade page if your lights dim, your main breaker keeps tripping, or your home still runs on fuses.
Related work on the same equipment lives on the meter base and service repair page, which covers storm, tree, and vehicle damage where the power line meets your house.
Mobile home electrical work is one of our two main services. If you are setting a single-wide or double-wide on new land, we can walk you through mobile home electrical hookups and power pole installation. If the home is already in place and something is wrong, the mobile home electrical repair page covers panels, dead outlets, and wiring problems.
When something stops working, start with electrical repair and troubleshooting for breakers that will not stay on, outlets that went dead, and half-the-house power loss. If there is sparking, a burning smell, or storm damage, the emergency electrician page explains what to do first and how we handle urgent calls.
A portable generator is only safe to connect to a house through the right equipment. Our generator transfer switch installation page explains how a transfer switch or inlet works and which circuits you can run during an outage.
Running power to a detached garage, a workshop, a barn, or a new room takes planning. See garage, shop and addition wiring for how we approach new circuits and outdoor service on rural Greene County property.
The everyday jobs are here too. Outlet, switch, and GFCI installation covers added outlets, 240-volt circuits, and protection for wet areas. Lighting and ceiling fan installation covers new fixtures, outdoor lighting, and fans on boxes that can carry them.
We also do whole-home rewiring, new construction electrical, EV charger installation and home electrical safety inspections, and we work with real estate investors and flippers. For storm or vehicle damage where the power line meets your house, see meter base and service repair.
