Epoxy Coating Services
Seamless epoxy floor coatings for garages, retail floors, showrooms, and warehouses — decorative to heavy-duty industrial.
Celebrity-mansion territory — full-scale estate remodels, structural transformations, and grounds construction executed with total discretion.
From metallic designer floors in Los Altos garages to high-build industrial systems in Central Valley warehouses, JMG's epoxy crews prepare, coat, and seal concrete that takes real abuse — grinding, moisture testing, and crack repair included on every job.
In Hillsborough and across San Mateo County, JMG delivers epoxy coatings under California Contractor's License #1007864 — permitted, inspected, and personally overseen by owner Jerry Guinn. Retail and commercial spaces get brand-color flake and quartz systems installed after hours; residential clients get garage, ADU, and showroom floors with slip-resistant, easy-clean finishes. Every system is specified for the traffic it will actually carry.
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.
