FAQ

Frequently Asked Questions
Got questions? We’ve got answers

How do I know if my home needs rewiring?

Signs include frequent breaker trips, flickering lights, discolored outlets, burning smell, two-prong outlets throughout, or wiring over 40 years old. Homes built before 1970 often need rewiring for safety and capacity.

How disruptive is a whole-home rewiring?

Modern rewiring techniques minimize disruption. We work room-by-room to keep most of your home functional. Drywall work is minimal with careful planning. Most homes take 3-7 days depending on size.

What is aluminum wiring and why is it a problem?

Aluminum wiring was used in the 1960s-70s. It expands/contracts more than copper, causing loose connections and fire risk. We recommend replacement or special connections for safety.

Can you add wiring without tearing up walls?

In many cases, yes! We use existing pathways, crawl spaces, and attics when possible. For renovations, we coordinate with your contractor to minimize wall damage and patching needs.

What's the difference between GFCI and AFCI protection?

GFCI protects against ground faults (shock risk) in wet areas like bathrooms and kitchens. AFCI protects against arc faults (fire risk) in bedrooms and living areas. Modern codes require both.

How much does rewiring cost?

Costs vary by home size and scope. Partial rewiring starts around $1,500-3,000. Whole-home rewiring typically $3,000-10,000. We provide detailed quotes after inspection with no hidden fees.
