Epoxy Coating Services
Seamless epoxy floor coatings for garages, retail floors, showrooms, and warehouses — decorative to heavy-duty industrial.
America's most exclusive zip code. Discreet, white-glove contracting for ultra-luxury estates and legacy Peninsula properties.
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 Atherton 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.
Atherton builds answer to the Town's Building Department on Station Lane — and to the heritage-tree ordinance that shapes where additions, ADUs, and driveways can land on the town's one-acre estate lots. We plan around protected oaks, manage design review, and deliver the discreet, high-touch project management Lindenwood and West Atherton estates expect.

Epoxy Coatings in Atherton — FAQ
