Remodels — Commercial & Residential
Whole-home renovations and retail build-outs, delivered design-build under one license.
Luxury remodels and custom ADUs in one of Silicon Valley's wealthiest family communities — where lot values reward estate-level craftsmanship.
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 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 Community Development guides projects through planning and building review with close attention to lot coverage and neighborhood scale. We remodel the city's classic ranch homes, build ADUs that respect its single-story streetscapes, and deliver downtown-adjacent commercial work without disrupting neighboring businesses.
