Frequently Asked Questions

What are the signs that my home needs a full rewire?

Warning signs include frequent circuit breaker trips, flickering lights, and a persistent burning smell near outlets. If your home still uses ungrounded two-prong outlets, cloth-insulated wiring, or aluminum wiring, the system is likely at the end of its safe operational life. These aging components can become brittle and pose a significant fire hazard as they struggle to handle modern electrical loads.

How long does it take to rewire an entire house?

A full house rewire typically takes between 5 and 10 days, depending on the size of the property and the accessibility of the wiring. The process involves pulling new cables through walls, replacing the electrical panel, and installing new outlets and switches. We work in stages to minimize the time any single area of your home is without power.

Do you have to cut into my walls to replace the wiring?

We use specialized tools to "fish" wires through existing wall cavities via the attic, crawlspace, or basement. While we aim for a non-invasive approach, small access holes are often necessary near the ceiling or behind outlets. We identify these points ahead of time so you can plan for minor drywall patching and painting once the new circuits are tested.

What is the difference between "partial" and "full" rewiring?

A partial rewire focuses on specific high-load areas, such as the kitchen or a new home office, or replaces only the most hazardous sections of an old system. A full rewire replaces every foot of cable from the electrical panel to the furthest outlet. In 2026, a full rewire is the only way to ensure 100% compliance with current safety codes and grounding requirements.

Why is "knob and tube" or "aluminum" wiring considered dangerous?

Knob and tube wiring lacks a ground wire and has insulation that becomes brittle and flakes off over time, exposing live copper. Aluminum wiring, common in the late 60s and 70s, expands and contracts more than copper, which leads to loose connections and arcing at outlets. Both systems are leading causes of residential electrical fires and often make a home uninsurable.

Will rewiring my home increase its resale value?

Yes. A modern, code-compliant electrical system is a major selling point and a standard requirement for home inspections. It provides buyers with peace of mind regarding fire safety and ensures the home can support modern technology and EV charging. Many insurance companies also lower premiums once a certified electrical rewire is completed.

Can I stay in my home while the rewiring is being done?

Most homeowners choose to stay, but you should expect significant disruption. Power will be shut off to specific sections of the house during the day, and there will be noise and dust as we access wall cavities. We provide a room-by-room schedule so you can plan your daily activities around the work zones.

Does a full rewire include adding more outlets and switches?

Yes. This is the ideal time to update your home's layout. We can add outlets for wall-mounted TVs, install USB-C charging ports, and add 240V circuits for appliances or EV chargers. We work with you during the planning phase to ensure the new electrical map meets your specific power needs in every room.

What is AFCI and GFCI protection, and is it included?

Modern electrical codes require AFCI (Arc Fault Circuit Interrupter) breakers to prevent fires caused by arcing wires and GFCI (Ground Fault Circuit Interrupter) protection in "wet" areas like kitchens and bathrooms to prevent shocks. A full rewire includes installing these safety devices at the panel or at the individual outlets to meet 2026 standards.

Do you provide emergency support if my old wiring fails?

Yes. If you experience a partial power failure, sparking outlets, or a "hot" wall, we provide 24/7 emergency diagnostics. Our team can isolate the hazardous circuit and provide a plan for immediate repair or replacement to secure your home and prevent an electrical fire.
