Lic #1007864 · Alameda County · MEP Engineering
Residential & Commercial Plumbing
Full-service residential and commercial plumbing — repipes, tankless systems, and ADA restrooms, engineered and guaranteed.
The Tri-Valley's premier suburb — upscale residential remodels, corporate office improvements, and retail maintenance programs.
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 Pleasanton and across Alameda 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.
Pleasanton's neighborhoods — from Vintage Hills to Ruby Hill — come with HOAs and design guidelines we satisfy before demo day. Vineyard-corridor estates, family-kitchen remodels, and retail work along Stoneridge and downtown Main Street all run through the city's permit center, which we manage end to end.

Plumbing in Pleasanton — 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.
