Whole-Home Rewiring
Complete residential rewiring for older homes, knob-and-tube replacement, aluminum wiring remediation, and renovation electrical work.
Why You Need This Service
Many Wisconsin homes were built with wiring that's now 50-100 years old. Knob-and-tube wiring, aluminum wiring, and outdated cloth-insulated wiring create serious fire hazards and often cause insurance problems. If your home has frequent breaker trips, flickering lights, two-prong outlets, or was built before 1970 without electrical updates, rewiring may be necessary for safety. Many insurance companies now require homes with knob-and-tube wiring to be rewired before they'll issue or renew policies.
What's Included
Typical Project Scope
A whole-house rewire typically takes 3-7 days depending on home size, accessibility, and the extent of the existing wiring. For a typical 1,500 sq ft ranch home, expect 3-4 days. Two-story homes or homes with limited attic/basement access may take longer. We minimize wall damage by fishing wires through existing pathways where possible. Drywall patching is included in our scope. We coordinate the municipal inspection for your final sign-off.
Our Process
Home Assessment
We inspect your existing wiring, panel, and outlets to determine the full scope. We identify knob-and-tube, aluminum, or other hazardous wiring and create a detailed plan.
Proposal & Permits
We provide a detailed written estimate and pull all required electrical permits. We'll explain what to expect during the rewire.
Circuit Rough-In
We run new copper wiring through your walls, attic, and basement. New circuits are roughed in for every room with proper GFCI/AFCI protection.
Panel & Connections
All new circuits are connected to a modern circuit breaker panel. Old wiring is disconnected and removed where accessible.
Trim & Test
New outlets, switches, and fixtures are installed. Every circuit is tested. Drywall is patched and the home is cleaned up.
Inspection & Certification
We schedule the municipal electrical inspection. You receive a certificate of compliance for your insurance company.
Frequently Asked Questions
How much does it cost to rewire a house in Wisconsin?
Whole-house rewiring in Wisconsin typically costs $8,000 to $20,000 depending on home size, number of circuits, accessibility, and whether the panel also needs upgrading. A 1,500 sq ft ranch may cost $8,000-$12,000 while a larger two-story home could be $15,000-$20,000.
How do I know if my home has knob-and-tube wiring?
Look in your attic or basement for ceramic knobs (white cylinders nailed to framing) and ceramic tubes (cylinders through joists). The wire is typically cloth-covered single conductors. If your home was built before 1950, there's a good chance it has some K&T wiring.
Will my insurance drop me for knob-and-tube wiring?
Many Wisconsin insurance companies will not issue new policies for homes with active knob-and-tube wiring, and some will cancel existing policies if K&T is discovered. Getting a rewire certificate is often required to maintain coverage.
Can you rewire a house without removing all the drywall?
Yes. Experienced electricians can fish new wires through existing wall cavities, attics, and basements with minimal wall damage. Some access holes are needed, but we include drywall patching in our rewiring scope.
