Silicon Valley · Santa Clara County · Luxury Remodels & ADUs
General Contractor
Luxury remodels and custom ADUs in one of Silicon Valley's wealthiest family communities — where lot values reward estate-level craftsmanship.
JMG Construction Services — California Contractor's License #1007864 — delivers all sixteen of our in-house trades to Los Altos and greater Santa Clara County. From estate remodels and custom ADUs to roofing, electrical, plumbing, and commercial HVAC, every Los Altos 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 Santa Clara County get one contract, one schedule, and one accountable license.
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.
