The Peninsula · San Mateo County · High-Income Residential
General Contractor
High-income residential remodeling minutes from Sand Hill Road — venture-capital discretion with builder-grade accountability.
JMG Construction Services — California Contractor's License #1007864 — delivers all sixteen of our in-house trades to Menlo Park and greater San Mateo County. From estate remodels and custom ADUs to roofing, electrical, plumbing, and commercial HVAC, every Menlo Park 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 San Mateo County get one contract, one schedule, and one accountable license.
Menlo Park runs from Allied Arts and Sharon Heights estates to Belle Haven infill — with flood-zone considerations near the Bay and a building department that expects complete submittals. We deliver estate remodels, retail work along Santa Cruz Avenue and El Camino Real, and ADUs engineered to the city's standards.
