Comprehensive electrical services for homes and businesses — licensed, insured, and backed by our workmanship guarantee.
Ceiling fans involve heavy fixtures and live wiring above your head. Our licensed electricians ensure every connection is secure, every mount is load-rated, and every fan runs safely.
Outdated wiring, missing ground wires, and improper connections are invisible dangers in thousands of homes. Our licensed inspectors identify every safety concern and prioritize what needs attention first.
We install a Type 2 surge protection device directly at your electrical panel, wire it to a dedicated double-pole breaker, and verify the grounding system that makes it effective.
From flickering lights and dead outlets to tripping breakers and buzzing switches, fast electrical repairs restore your home to safe, reliable operation and give you peace of mind.
We design a custom layout, install a weatherproof transformer, run buried low-voltage cable to each fixture location, and program timers or photocells for effortless automated operation.
We disconnect the utility feed, swap your outdated panel for a modern load center, re-land every circuit on correctly rated breakers, and coordinate the final inspection with your municipality.
A properly installed standby generator protects your family, your food supply, and your medical equipment. We pull all permits and ensure code-compliant connections every time.
Add outlets exactly where you need them and eliminate extension cord clutter. New outlets improve convenience, reduce fire hazards, and increase your home value.
We plan the new circuit layout, pull permits, run code-compliant copper wiring through your walls and attic, install a new panel if needed, and restore your walls with minimal disruption.
EV chargers draw significant power and require proper circuit protection. Our licensed electricians ensure your installation meets NEC code, manufacturer specs, and local requirements.
Aluminum wiring installed in homes from the 1960s and 1970s is a documented fire hazard. Replacing it with modern copper wiring dramatically reduces your risk and may lower your insurance premiums.
We install hardwired CO detectors at code-required locations near bedrooms and fuel-burning appliances, interconnect them with your smoke alarm system, and verify operation with professional testing equipment.
Commercial electrical work requires strict code compliance, proper load calculations, and coordination with inspectors and general contractors. Our licensed commercial electricians deliver permitted, inspected, and insured work on every project.
Recessed lights create a clean, modern look while flooding your rooms with even illumination. LED recessed fixtures also cut your lighting energy use by up to 75 percent.
Stop guessing why your power is acting up. Professional electrical troubleshooting pinpoints hidden problems fast, saving you time and preventing damage to your home and devices.
Breakers that trip repeatedly are warning you of a serious problem. Forcing them back on risks fire or electrocution. Our electricians safely diagnose whether the issue is the breaker, the wiring, or an overload.
We install smart switches, dimmers, and outlets that work with your existing Wi-Fi network, set up automation routines, and ensure every device has the neutral wire and load capacity it requires.
We remove old fixtures, upgrade the electrical box if needed, connect and mount the new fixture securely, and test dimmer compatibility so your lights perform exactly as expected.
Water and electricity are a deadly combination. Pool and hot tub wiring requires GFCI protection, proper bonding of all metal surfaces, and specific clearance distances. Our electricians follow NEC Article 680 to the letter.
We run Cat6 or coax cable from each camera location to your DVR or NVR, mount cameras at optimal angles, install weatherproof junction boxes, and power everything through a centralized system.
We install hardwired smoke detectors in every required location, interconnect them so all units sound together, add battery backup, and test the full system before we leave.
We review your project requirements, pull necessary permits, install wiring and devices using commercial-grade materials, and schedule the final inspection to close out the permit properly.
Improper doorbell wiring can damage your transformer or void your warranty. Our electricians verify voltage, test connections, and ensure your Ring operates safely and reliably.
