Exterior lighting estimates for South Shore homes depend on fixture selection and quantity, existing wiring, new wiring routes, controls, and installation access. Fixture supply, mounting requirements, and control compatibility affect the proposed work. High mounting locations, trenching, and access around paving, decks, or planting beds may add to the scope. When comparing estimates, check fixture models, quantities, locations, wiring, controls, and setup. Confirm whether permits, inspections, trenching, and finish repairs are included where applicable, and ask how changes to the agreed scope will be handled.
