Painting — Commercial & Residential
Commercial and residential painting — museum-grade interior and exterior finishes for estates, retail flagships, and portfolios.
America's most exclusive zip code. Discreet, white-glove contracting for ultra-luxury estates and legacy Peninsula properties.
From celebrity estates in Hillsborough to Starbucks retail interiors across the Bay Area, JMG delivers flawless paint systems with meticulous surface preparation, premium coatings, and clean, protected job sites. Every project is supervised under California Contractor's License #1007864.
In Atherton and across San Mateo County, JMG delivers painting under California Contractor's License #1007864 — permitted, inspected, and personally overseen by owner Jerry Guinn. We handle occupied-home protocols, brand-standard commercial color matching, and high-durability exterior systems engineered for California sun, fog, and coastal air — on schedule and inspection-ready.
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.
