Retail Maintenance & Rapid Responsein Walnut Creek, CA.

The crew national brands call — multi-site retail maintenance from San Francisco to San Diego.

The East Bay's retail capital — Broadway Plaza-caliber tenant improvements, striping, and luxury home upgrades in the surrounding hills.

JMG keeps retail portfolios open and immaculate: punch-list turnarounds, fixture and signage repair, painting, drywall, and emergency response delivered to brand standards — including work for Starbucks locations.

In Walnut Creek and across Contra Costa County, JMG delivers retail maintenance under California Contractor's License #1007864 — permitted, inspected, and personally overseen by owner Jerry Guinn. One call covers every trade. Our after-hours crews work while your stores are closed, so revenue is never interrupted and corporate inspections always pass.

Walnut Creek pairs a high-traffic downtown retail core with hillside neighborhoods in Saranap and Northgate. Retail refreshes downtown demand night work and zero downtime; hillside homes demand fire-safe materials and defensible-space detailing. JMG crews handle both on one schedule.
