Residential & Commercial Plumbing
Full-service residential and commercial plumbing — repipes, tankless systems, and ADA restrooms, engineered and guaranteed.
The Capital Region's growth corridor — commercial development, metro residential remodels, and our northern anchor for statewide coverage.
From copper and PEX whole-house repipes in Atherton estates to ADA-compliant commercial restrooms, JMG's plumbing division handles rough-in through finish fixtures with in-house accountability.
In Sacramento and across Sacramento County, JMG delivers plumbing under California Contractor's License #1007864 — permitted, inspected, and personally overseen by owner Jerry Guinn. We coordinate directly with our HVAC and electrical crews, so remodels, ADUs, and tenant improvements move through inspection without costly trade conflicts.
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.

Plumbing in Sacramento — FAQ
We plan PEX or copper routes through attics and crawlspaces to minimize openings — and because our sheet rock and paint crews are in-house, every patch disappears on the same job ticket.
