When it comes to keeping your home or business running safely and efficiently, few things matter more than your electrical wiring and panel.

Whether you’re building new, renovating, or troubleshooting old wiring, our licensed electricians ensure your system meets today’s electrical demands — safely, neatly, and to code.

Frequent tripped breakers or blown fuses: A sign your panel is undersized or your circuits are overloaded.
Home additions or remodeling: New rooms or appliances often require new wiring or a higher-capacity panel.
Outdated fuse boxes: Older homes with fuse panels or knob-and-tube wiring need upgrades for safety and reliability.
Flickering or dimming lights: Indicates voltage fluctuations, loose wiring, or a failing connection.
Electrical shocks or burning smells: Critical safety hazards that should be inspected immediately.
Insufficient outlets: Adding outlets requires new circuits or rewiring to meet today’s household needs.

Whether you’re renovating a home in Hamden, outfitting a new retail space in Wallingford, or bringing an older property up to code in East Haven, our licensed electricians can handle it all — safely, efficiently, and professionally.

Things to Consider When Getting Wiring or Electrical Panel Work Done

Electrical work is one of those things you don’t want to cut corners on. Before you hire any electrician in Connecticut, consider the following:

Code compliance: Electrical systems must meet Connecticut State Building Codes and local town requirements. Cahill Electrical Services handles permitting, inspections, and compliance from start to finish.
Capacity needs: Your electrical panel should handle both current and future load requirements — especially if you plan to add an EV charger, heat pump, or new appliances.
Material quality: We use top-rated panels, breakers, and wiring to ensure longevity and safety.
Professional installation: Poor workmanship leads to fire risks, flickering lights, and tripped breakers. Our licensed team ensures clean, safe, and organized wiring throughout your property.
Upgrade timing: If your home or building is over 25 years old, it’s often wise to inspect and upgrade wiring before expanding or remodeling.
