Silicon Valley · Santa Clara County · Estate Contracting
General Contractor
Estate contracting for hillside properties, vineyard-adjacent residences, and custom homes in the foothills of the Santa Cruz Mountains.
JMG Construction Services — California Contractor's License #1007864 — delivers all sixteen of our in-house trades to Saratoga and greater Santa Clara County. From estate remodels and custom ADUs to roofing, electrical, plumbing, and commercial HVAC, every Saratoga 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.
Saratoga projects near the Village respect its historic character, while hillside homes fall under the city's hillside development standards — grading limits, view protection, and engineered drainage. From Saratoga Village storefront refreshes to hillside estate rebuilds, we coordinate the review boards so approvals never stall your build.
