Electrical — Commercial & Residential
Licensed electrical work from panel upgrades and EV charging to retail lighting maintenance programs.
Our home base — Silicon Valley's capital, where JMG delivers high-end residential remodels, custom ADUs, and commercial build-outs across every district.
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 San Jose and across Santa Clara 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.
San Jose projects run through the City's Permit Center and the SJplans online portal — and San Jose's pre-approved ADU plan program can shave weeks off a backyard-unit timeline. From Willow Glen and Cambrian ranch remodels to Almaden Valley estates and downtown tenant improvements, JMG manages submittals, plan-check corrections, and inspections end to end.
