Lic #1007864 · Sacramento County · MEP Engineering
Electrical — Commercial & Residential
Licensed electrical work from panel upgrades and EV charging to retail lighting maintenance programs.
The Capital Region's growth corridor — commercial development, metro residential remodels, and our northern anchor for statewide coverage.
JMG designs and installs electrical systems for high-demand modern living — 200A+ panel upgrades, whole-estate lighting, EV charging, and dedicated circuits for luxury kitchens and home theaters across Silicon Valley.
In Sacramento and across Sacramento County, JMG delivers electrical under California Contractor's License #1007864 — permitted, inspected, and personally overseen by owner Jerry Guinn. For retail and commercial clients, we deliver code corrections, lighting retrofits, and rapid-response maintenance that keeps storefronts lit and operational from San Francisco to San Diego.
Sacramento's older housing stock — the Fab Forties, Land Park, East Sac — rewards contractors who respect original details, while Central Valley heat makes HVAC and envelope work mission-critical. Permits run through the city's Community Development Department, and our retail crews cover the full corridor from the Bay Area to the Valley.
