Sheet Rock Installation
Precision drywall installation — from Level 5 estate finishes to fire-rated commercial assemblies.
High-end residential remodels and commercial projects in the heart of Apple country — precision work for precision-minded clients.
JMG hangs, tapes, and finishes sheet rock to exacting tolerances for luxury residences and commercial tenant improvements from San Jose to Sacramento. Smooth-wall Level 5 finishes, curved details, and acoustic assemblies are our signature.
In Cupertino and across Santa Clara County, JMG delivers sheet rock under California Contractor's License #1007864 — permitted, inspected, and personally overseen by owner Jerry Guinn. Our in-house crews coordinate directly with our framing, electrical, and plumbing divisions, eliminating trade-gap delays and delivering inspection-ready walls on compressed schedules.
Cupertino remodels are driven by families and its school district — kitchen expansions, garage conversions, and ADUs for multigenerational living top the list. The city's online permit portal keeps submittals moving, and our in-house trades keep occupied-family-home projects clean, quiet, and on schedule.
