Sheet Rock Installation
Precision drywall installation — from Level 5 estate finishes to fire-rated commercial assemblies.
Celebrity-mansion territory — full-scale estate remodels, structural transformations, and grounds construction executed with total discretion.
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 Hillsborough and across San Mateo 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.
Hillsborough requires design review through the Town's Building & Planning Department, and its hillside estates bring slope, drainage, and retaining-wall engineering into nearly every project. From Hillsborough Oaks to the Carolands area, we coordinate geotechnical reports, view-sensitive design, and the town's exacting inspection standards.
