Residential & Commercial Plumbing
Full-service residential and commercial plumbing — repipes, tankless systems, and ADA restrooms, engineered and guaranteed.
Historic downtown Victorians and hillside modern estates — remodels and additions that honor character while adding serious square footage.
From copper and PEX whole-house repipes in Atherton estates to ADA-compliant commercial restrooms, JMG's plumbing division handles rough-in through finish fixtures with in-house accountability.
In Los Gatos and across Santa Clara County, JMG delivers plumbing under California Contractor's License #1007864 — permitted, inspected, and personally overseen by owner Jerry Guinn. We coordinate directly with our HVAC and electrical crews, so remodels, ADUs, and tenant improvements move through inspection without costly trade conflicts.
Los Gatos blends a historic downtown commercial district with hillside neighborhoods like Belgatos and Alta Vista — each with its own review path. Historic-district storefront work follows the town's preservation guidelines; hillside homes need grading and erosion-control plans. JMG runs both under one contract and one schedule.

Plumbing in Los Gatos — FAQ
We plan PEX or copper routes through attics and crawlspaces to minimize openings — and because our sheet rock and paint crews are in-house, every patch disappears on the same job ticket.
