Simmons & Wood Inc on Lakeside's Winter Gardens Blvd corridor holds dual CSLB licenses #272910 and #270296 (C-33 Painting and Decorating) and has operated continuously since its 1971 founding. The firm's commercial division handles specialty ceilings, acoustic treatment, gypsum board finishing, and wall-covering installation alongside large-format painting — the kind of multi-trade interior scope that dovetails with the hardwood and tile work at Christian Brothers Flooring & Interiors on Woodside Ave. More than five decades in the East County market have built a project history spanning medical offices, retail build-outs, and multi-family complexes requiring coordinated finish schedules. Commercial paint-and-plaster packages often run concurrent with mechanical rough-in from HVAC contractors like Precision Temperature, which shares the same Woodside Ave industrial pocket. Scope on the largest tenant-improvement projects includes Level 5 drywall finish, vinyl wall-covering adhesion, suspended acoustical-ceiling grid installation, and high-build epoxy floor coatings applied to concrete substrates.
