Commercial painting covers the buildings homeowners' contractors usually don't touch: offices, retail storefronts, restaurants, warehouses, medical suites, apartment buildings, and HOA common areas. The work is different from a house repaint in scale and constraints. Crews often paint around business hours, work nights or weekends to avoid closing a shop, mask off inventory or equipment, and use commercial-grade coatings built for heavy foot traffic, grease, or repeated cleaning. Jobs can also involve line striping in parking lots, epoxy floor coatings, or matching a franchise's exact brand colors across multiple locations.
Before hiring, ask for proof of commercial general liability insurance and workers' comp, since a crew working in an occupied building or on a lift creates real exposure. Ask how they schedule around your operating hours, whether they've handled a space your size before, and for references from other commercial clients, not just homeowners. A written scope with square footage, prep steps (patching, priming, pressure washing), paint brand and sheen, and a timeline protects you if the job runs long. For older buildings, ask how they handle lead paint testing and containment.
