Commercial painting covers the interior and exterior work that keeps offices, retail spaces, restaurants, warehouses, and multi-unit buildings looking presentable and protected: office suites and lobbies, storefronts, common areas in apartment or condo buildings, warehouse and industrial floors and walls, parking garage striping, and exterior siding, trim, or masonry on commercial structures. It differs from residential painting mainly in scale and logistics. Jobs often need to happen after hours or on weekends to avoid disrupting tenants or customers, crews need to be insured for liability well beyond a typical house job, and surfaces like metal siding, cinder block, or drywall in high-traffic corridors need different prep and coatings than a living room wall.
When you're comparing painters for a commercial job in Groton, ask about a few things up front: current liability insurance and workers' comp (a property manager or landlord will usually require proof), experience with your building type (retail buildup differs from office or industrial), whether they handle surface prep like patching, pressure washing, or rust treatment on metal, what paint brands and warranty they use, and how they schedule around your operating hours. Get a written scope and timeline, not just a price, since commercial jobs can slip if a crew is juggling other contracts.
