Retail Maintenance & Rapid Response
The crew national brands call — multi-site retail maintenance from San Francisco to San Diego.
America's most exclusive zip code. Discreet, white-glove contracting for ultra-luxury estates and legacy Peninsula properties.
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 Atherton and across San Mateo 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.
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.
