In Hillsborough and across San Mateo County, JMG delivers painting under California Contractor's License #1007864 — permitted, inspected, and personally overseen by owner Jerry Guinn. We handle occupied-home protocols, brand-standard commercial color matching, and high-durability exterior systems engineered for California sun, fog, and coastal air — on schedule and inspection-ready.
Hillsborough requires design review through the Town's Building & Planning Department, and its hillside estates bring slope, drainage, and retaining-wall engineering into nearly every project. From Hillsborough Oaks to the Carolands area, we coordinate geotechnical reports, view-sensitive design, and the town's exacting inspection standards.
