Lic #1007864 · Contra Costa County · Drywall & Framing
Sheet Rock Installation
Precision drywall installation — from Level 5 estate finishes to fire-rated commercial assemblies.
Blackhawk-adjacent luxury — gated-community remodels, outdoor living construction, and estate grounds work.
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 Danville and across Contra Costa 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.
Danville projects often answer to two authorities: the Town's building division and an HOA design-review board — Blackhawk most famously. We prepare HOA submittal packages, manage the town's permit process, and build the estate remodels, outdoor structures, and ADUs that define Diablo-adjacent living.

Sheet Rock in Danville — FAQ
Most homes get a Level 4 finish; high-end estates and critical-light walls get a Level 5 smooth-wall skim coat. Commercial fire-rated assemblies follow the engineer's specification. We recommend the level after walking the space with you.
