Residential & Commercial Plumbing
Full-service residential and commercial plumbing — repipes, tankless systems, and ADA restrooms, engineered and guaranteed.
Estate contracting for hillside properties, vineyard-adjacent residences, and custom homes in the foothills of the Santa Cruz Mountains.
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 Saratoga 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.
Saratoga projects near the Village respect its historic character, while hillside homes fall under the city's hillside development standards — grading limits, view protection, and engineered drainage. From Saratoga Village storefront refreshes to hillside estate rebuilds, we coordinate the review boards so approvals never stall your build.

Plumbing in Saratoga — 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.
