Can you work to our brand standards?

That is the job. We build to your facilities playbook — approved materials, color standards, signage specs — and document completion with photos your facilities team can audit.

Do you handle multi-site programs?

One contract covers the portfolio: punch lists, refreshes, rollouts, and emergency calls across every location, with per-site reporting.

Retail Maintenance & Rapid Responsein San Jose, CA.

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

Our home base — Silicon Valley's capital, where JMG delivers high-end residential remodels, custom ADUs, and commercial build-outs across every district.

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 San Jose and across Santa Clara 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.

San Jose projects run through the City's Permit Center and the SJplans online portal — and San Jose's pre-approved ADU plan program can shave weeks off a backyard-unit timeline. From Willow Glen and Cambrian ranch remodels to Almaden Valley estates and downtown tenant improvements, JMG manages submittals, plan-check corrections, and inspections end to end.
