Nantucket Electrician & Lighting | Granite Island Electric Supply Co.

Our comprehensive electrical inspections specifically check for the corrosion and wear that Nantucket's salt air causes on outdoor outlets, connections, and wiring. We identify early signs of damage before they lead to failure or become a safety hazard, allowing for proactive repair or replacement to keep your outdoor spaces safe and functional.

If you notice flickering lights, outlets that don't work, or signs of rodents, it's crucial to act quickly. Turn off power to the affected area if safe to do so and call us immediately. Our electricians specialize in diagnosing and repairing rodent-damaged wiring. We safely replace the compromised sections, often recommending protective conduit or other solutions to prevent future issues common in our island environment.

Absolutely. We not only install and repair all types of light fixtures, but we also help you select fixtures rated for wet or damp locations, which are essential for durability against our island's moisture and salt spray. Our installation ensures proper sealing and grounding to prevent corrosion and electrical faults, providing safe, long-lasting illumination for your property.
