Remodels — Commercial & Residential
Whole-home renovations and retail build-outs, delivered design-build under one license.
High-end residential remodels and commercial projects in the heart of Apple country — precision work for precision-minded clients.
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 Cupertino 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.
Cupertino remodels are driven by families and its school district — kitchen expansions, garage conversions, and ADUs for multigenerational living top the list. The city's online permit portal keeps submittals moving, and our in-house trades keep occupied-family-home projects clean, quiet, and on schedule.
