Residential & Commercial Plumbing
Full-service residential and commercial plumbing — repipes, tankless systems, and ADA restrooms, engineered and guaranteed.
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.
We coordinate directly with our HVAC and electrical crews, so remodels, ADUs, and tenant improvements move through inspection without costly trade conflicts.

How it works
Private Consultation
Walk the property with owner Jerry Guinn. Honest scope, realistic timeline, and a written line-item estimate — free.
Design & 3D Rendering
See the finished project in photorealistic 3D before a single wall comes down. Finishes get locked before demo day.
Permits, Handled
Plans, submittals, corrections, and city or county coordination under CA License #1007864. You sign — we run the process.
Build & Final Inspection
Sixteen in-house trades on one schedule, one accountable owner. Inspection passed, walkthrough done, keys in hand.
Plumbing — frequently asked questions
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.
