Complete Home Rewiring & Electrical Modernization

A full house rewire transforms your home’s electrical foundation, protecting your property value while bringing every room up to current National Electrical Code (NEC) standards.

Knob and Tube Wiring Replacement: Common in Salem homes built before 1950, knob and tube wiring lacks a grounding conductor, degrades rapidly under modern power loads, and frequently leads to homeowners insurance denying coverage. We safely decommission and replace complete knob and tube systems with modern, grounded Romex® wiring.

Aluminum & Cloth-Covered Wiring Upgrades: Homes constructed between the 1960s and 1970s often feature aluminum wiring or cloth-insulated lines. These materials expand and loosen over time, creating severe arc-fault fire risks. Our team performs complete aluminum wiring replacements to eliminate fire hazards at every connection point.

Ungrounded Circuit Upgrades & 3-Prong Outlets: If your home still relies on two-prong wall receptacles, your sensitive electronics and major appliances are at constant risk. We replace two-prong setups with grounded, code-compliant three-prong outlets, GFCI receptacles, and AFCI breaker protection.

Rewiring & 200-Amp Panel Upgrades: A whole-home rewire is the ideal time to upgrade to a 200-amp service panel. We modernize your entire system at once, ensuring your service panel can easily power modern HVAC units, kitchen remodels, EV chargers, and smart home technology.
