Common Electrical Repairs – Residential & Commercial
Electrical Wiring Repair & Replacement
Damaged, outdated, or improperly installed wiring poses serious safety risks including electrical fires and shock hazards. Our electrical wiring repair services include identifying faulty connections, replacing deteriorated wiring, and upgrading electrical systems to meet current safety codes. We work with all types of wiring including aluminum, copper, and knob-and-tube systems in older homes throughout Jefferson County.
GFCI Outlet Installation & Repair
Ground Fault Circuit Interrupter (GFCI) outlets are required by electrical code in bathrooms, kitchens, garages, and outdoor areas to prevent electrical shock. If your GFCI outlets aren't functioning properly—tripping frequently, not resetting, or failing to provide protection—we'll diagnose the problem and install new GFCI outlets that meet current safety standards.
Electrical Panel Upgrades & Service Changes
Older electrical panels often can't handle the electrical demands of modern homes and businesses. Our electrical panel upgrade services include replacing outdated fuse boxes, upgrading electrical service capacity from 100-amp to 200-amp systems, relocating electrical panels for code compliance, and installing new circuit breakers that provide reliable electrical distribution throughout your property.
Circuit Breaker & Electrical System Troubleshooting
Constantly tripping circuit breakers indicate underlying electrical problems that require professional diagnosis. We use specialized testing equipment to identify overloaded circuits, short circuits, ground faults, and other electrical issues. Our circuit breaker repair services restore proper electrical function and prevent dangerous electrical conditions that could damage appliances or create fire hazards.
