Comprehensive electrical services for homes and businesses — licensed, insured, and backed by our workmanship guarantee.
We examine your panel, wiring, outlets, switches, grounding system, and GFCI protection room by room, then deliver a detailed written report with findings and recommended corrections.
We assess your panel capacity, install a dedicated 240V circuit, mount the charging unit in your garage or driveway, and handle all permits and inspections from start to finish.
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.
Outdoor wiring must withstand moisture, temperature swings, and soil contact. Our electricians use UL-listed wet-rated fixtures, GFCI-protected circuits, and proper burial depths to ensure lasting safety.
Keep your home powered through any outage with a professionally installed backup generator. Enjoy uninterrupted comfort and security when the grid goes down.
An upgraded electrical panel supports modern power demands, prevents tripped breakers, and can increase your home value. Stop managing an overloaded system and power your home with confidence.
Add outlets exactly where you need them and eliminate extension cord clutter. New outlets improve convenience, reduce fire hazards, and increase your home value.
Control your lights, thermostats, locks, and more from your phone or voice assistant. Smart home wiring creates a connected, energy-efficient home that simplifies your daily routine.

Professionally wired security cameras deliver reliable 24/7 recording without Wi-Fi dropouts or battery hassles. Protect your home and family with a surveillance system you can count on.
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.

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.
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 map out fixture placement for optimal light coverage, cut precise ceiling openings, run new circuits as needed, and install IC-rated housings that are safe for insulated ceilings.
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.
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.
Ignoring electrical problems lets them get worse. Loose connections, arcing wires, and overloaded circuits cause thousands of house fires each year. Our licensed team fixes issues safely, the first time.
Electrical installations done without permits or by unlicensed workers put your family at risk and can void your insurance. Our licensed electricians deliver code-compliant, inspected work on every job.
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.
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.
