Why Replace Old Wiring
Eliminate Fire Hazards
Knob-and-tube and single-strand aluminum wiring are leading causes of electrical fires in older homes. Modern copper NM cable with grounded conductors removes that risk.
Support Modern Loads
Old wiring was sized for far fewer appliances. Modern wiring safely handles today's loads, EV chargers, and smart-home systems without overheating.
Lower Insurance & Raise Value
Many insurers won't write or renew policies on homes with knob-and-tube or aluminum wiring. A documented rewire makes your home insurable and more valuable.
Our Wiring Replacement Process
Wiring Survey
We inspect accessible wiring, identify knob-and-tube or aluminum circuits, and document what's present and what needs replacement.
Scope & Quote
We give you a clear plan — full rewire, targeted replacement, or remediation — with upfront, itemized pricing and a permit strategy.
Clean Rewire
We pull new Romex with minimal drywall disruption, fish through finished walls, and label every circuit at the panel.
Inspect & Document
We pull the permit, pass the rough and final inspections, and hand you documentation for insurance and resale.
Wiring Repair Questions
Q.Is knob-and-tube wiring dangerous?
It can be. Knob-and-tube has no ground, insulation that degrades over decades, and was never designed for modern loads. It's also often been improperly modified over the years. We recommend replacement, especially before insulating walls or remodeling.
Q.I have aluminum wiring — what should I do?
Single-strand aluminum branch wiring (common in 1965–1973 homes) can overheat at connections and is a known fire risk. We remediate it with COPE-approved connectors and pigtailing to copper at every device, or replace the circuits entirely — both are code-accepted solutions.
Q.How long does a whole-home rewire take?
It depends on home size and accessibility. A typical single-story rewire takes 3–5 days; a two-story or finished-basement home can take 1–2 weeks. We give you a clear timeline before starting and keep your home livable during the work.
Q.Will my insurance require a rewire?
Many insurers now decline or non-renew policies on homes with active knob-and-tube or single-strand aluminum wiring. A permitted, inspected rewire with documentation usually resolves the issue — we provide everything you need for your agent.
