Capital Region · Sacramento County · Commercial & Metro Development
General Contractor
The Capital Region's growth corridor — commercial development, metro residential remodels, and our northern anchor for statewide coverage.
JMG Construction Services — California Contractor's License #1007864 — delivers all sixteen of our in-house trades to Sacramento and greater Sacramento County. From estate remodels and custom ADUs to roofing, electrical, plumbing, and commercial HVAC, every Sacramento project is personally scoped by owner Jerry Guinn and executed by our own crews — never brokered to unknown subcontractors.
Whether the brief is a celebrity-grade whole-estate renovation, a discreet retail maintenance program, or a high-value ADU addition, our clients across Sacramento County get one contract, one schedule, and one accountable license.
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.
