Epoxy Coating Services
Seamless epoxy floor coatings for garages, retail floors, showrooms, and warehouses — decorative to heavy-duty industrial.
Blackhawk-adjacent luxury — gated-community remodels, outdoor living construction, and estate grounds work.
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 Danville and across Contra Costa 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.
Danville projects often answer to two authorities: the Town's building division and an HOA design-review board — Blackhawk most famously. We prepare HOA submittal packages, manage the town's permit process, and build the estate remodels, outdoor structures, and ADUs that define Diablo-adjacent living.

Epoxy Coatings in Danville — FAQ
