SBI Interiors provides commercial interior and exterior construction services across the Bay Area, backed by a California C2, C-9, and C35 contractor license (#983778). From structural framing to finish work, our crews handle each trade with the same standard: built right, on schedule, with safety first.
Structural & Light-Gauge Framing
Expert metal stud framing for complex commercial applications — from high-rise tenant improvements to ground-up structural buildouts. Our framing crews work directly off architectural drawings to hold tight tolerances on layout, blocking, and load-bearing assemblies, setting the foundation for every trade that follows.
Drywall & Specialized Wall Finishes
High-performance wall installations with modern smooth and textured finishes, licensed under our C-9 Drywall classification. We handle everything from standard partition walls to fire-rated assemblies and specialty finishes for medical, retail, and corporate environments where wall performance and appearance both matter.
Suspended Ceiling Systems
Certified installers for Armstrong, USG, and CertainTeed ceiling systems, ranging from medical-grade cleanroom ceilings to custom architectural grid work — covered under our C2 Insulation & Acoustical classification. Our teams are experienced with the tight coordination suspended ceilings require alongside mechanical, electrical, and fire suppression trades.
Lath & Plaster
Traditional three-coat and modern veneer plaster systems for both interior and exterior applications, performed under our C35 Lathing & Plastering classification. Whether it's a durable stucco exterior or a seamless decorative interior finish, our plaster crews bring the kind of craftsmanship that's increasingly hard to find in commercial construction.
Spray Fire-Proofing
Sprayed fire-resistive material (SFRM) applied to structural steel and decking to meet fire code and life-safety requirements on commercial projects. Fire-proofing is one of the most inspection-sensitive parts of any buildout — our crews are experienced with the coverage thicknesses, bond strength, and code-mandated inspection sign-offs required to keep a project moving through final approval.
Sustainability & Safety
We build with LEED compliance and material recycling in mind on every applicable project, and safety isn't a slogan here — it's the standard we hold every crew to on every job site. Learn more about LEED certification.
