Killingly's trusted source for licensed electrical services — from outlet repairs to full panel upgrades, done right the first time.
Whether it's a simple outlet repair or a complex commercial build-out, our electricians deliver professional results every time.
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.
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.
We disconnect the utility feed, swap your outdated panel for a modern load center, re-land every circuit on correctly rated breakers, and coordinate the final inspection with your municipality.
We test the suspect breaker with calibrated equipment, check for loose bus connections and signs of arcing, replace the faulty breaker with a matching UL-listed unit, and load-test the circuit.
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.
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.
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.
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.
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.
Our electricians diagnose the root cause of the problem, explain the repair before starting, fix the issue with commercial-grade materials, and test the circuit to confirm a lasting solution.
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.
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.
CO detector placement matters as much as having one. Installed too high, too low, or too far from sources, they may not alarm in time. Our electricians follow manufacturer and code guidelines precisely.
We use thermal imaging, multimeters, and circuit analyzers to trace faults through your wiring, identify the exact failure point, and recommend the most cost-effective repair.
EV chargers draw significant power and require proper circuit protection. Our licensed electricians ensure your installation meets NEC code, manufacturer specs, and local requirements.
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.
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.
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.
Add outlets exactly where you need them and eliminate extension cord clutter. New outlets improve convenience, reduce fire hazards, and increase your home value.
Homes built before 1980 often have degraded insulation, undersized circuits, or knob-and-tube wiring that insurance companies flag as unacceptable. Our licensed electricians bring your wiring up to current NEC standards.
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.
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.
