Lic #1007864 · Santa Clara County · General Contracting
Remodels — Commercial & Residential
Whole-home renovations and retail build-outs, delivered design-build under one license.
Acre-plus hillside estates with demanding engineering — retaining structures, long driveways, and architect-driven custom construction.
JMG runs full-scope remodels: celebrity-mansion kitchens and baths, whole-home transformations in Palo Alto and Menlo Park, and fast-track retail tenant improvements for national brands.
In Los Altos Hills and across Santa Clara County, JMG delivers remodels under California Contractor's License #1007864 — permitted, inspected, and personally overseen by owner Jerry Guinn. With 16 trades in-house, there is no subcontractor carousel — one contract, one schedule, one accountable owner: Jerry Guinn, Lic #1007864.
Los Altos Hills keeps its rural character by rule: one-acre minimum lots, private lanes, the town pathway system, and properties that may run on septic rather than sewer. Projects here demand site-sensitive engineering and careful utility planning — exactly the ground-up estate work JMG self-performs with in-house crews.
