Comprehensive electrical services for homes and businesses — licensed, insured, and backed by our workmanship guarantee.
A whole-house surge protector shields every appliance, device, and electronic system in your home from voltage spikes. One device at the panel protects thousands of dollars in equipment.
We handle tenant improvements, lighting retrofits, panel upgrades, dedicated equipment circuits, emergency power systems, and code compliance upgrades for commercial and industrial spaces.
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.
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.
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.
We disconnect the utility feed, swap your outdated panel for a modern load center, re-land every circuit on correctly rated breakers, and coordinate the final inspection with your municipality.
Our licensed electricians handle every step of your generator install, from sizing the unit and pouring the pad to wiring the automatic transfer switch and final testing.
We mount your Ring doorbell at the optimal height, run low-voltage wiring from your existing doorbell transformer, and configure the app so you are up and running in one visit.
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.
Charge your electric vehicle overnight at home and wake up with a full battery every morning. A Level 2 charger delivers up to 10x faster charging than a standard outlet.
An electrical inspection reveals hidden hazards, code violations, and aging components before they cause problems. Protect your investment whether you are buying, selling, or simply maintaining your home.
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.
Aluminum wiring expands and contracts more than copper, causing loose connections that overheat and arc. Insurance companies increasingly refuse to cover aluminum-wired homes. Our licensed electricians eliminate the risk permanently.
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.
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.
Our electricians locate the nearest power source, run new wiring through your walls, install the outlet box, and test the circuit to confirm safe, reliable operation.
We install a dedicated 240V circuit from your panel to the equipment pad, wire the GFCI disconnect within sight of the unit, bond all metal components, and verify ground fault protection.
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.
Heavy chandeliers, track lighting, and pendant fixtures require properly rated electrical boxes and secure mounting. Our electricians ensure every installation is safe, level, and wired correctly.
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 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.
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.
Electrical problems often hide behind walls where they quietly worsen. Our licensed electricians follow a systematic diagnostic process to find issues before they become fire hazards or safety threats.
