Commercial & Residential Landscaping
Full-service commercial and residential landscaping — estate gardens, retail grounds, hardscape, and smart irrigation across California.
Acre-plus hillside estates with demanding engineering — retaining structures, long driveways, and architect-driven custom construction.
JMG's landscaping division serves both sides of California: estate gardens and outdoor living for residential clients, and grounds programs for retail centers, campuses, and commercial properties — from the Bay Area to Sacramento, and San Francisco to San Diego.
In Los Altos Hills and across Santa Clara County, JMG delivers landscaping under California Contractor's License #1007864 — permitted, inspected, and personally overseen by owner Jerry Guinn. Drought-tolerant conversions, smart irrigation, architectural lighting, and hardscape are engineered for beauty and for California's water reality — installed and maintained by the same in-house team.
Los Altos Hills keeps its rural character by rule: one-acre minimum lots, private lanes, the town pathway system, and properties that may run on septic rather than sewer. Projects here demand site-sensitive engineering and careful utility planning — exactly the ground-up estate work JMG self-performs with in-house crews.
