We Replace Outdated Wiring Systems

We handle knob & tube replacement for homes and businesses across the Triangle. Knob &#038. Tube replacement is essential for older homes built before 1950. This outdated wiring lacks a ground wire. It cannot handle modern electrical loads safely. We remove old ceramic insulators and cloth-wrapped wires from your home. Then we install new Romex cable that meets current NEC Article 334 standards. Our electricians fish new 14/2 and 12/2 wire through your walls. We do not tear up your entire home. We pull permits for every job. We coordinate inspections with local building departments. Most insurance companies will not cover homes with active knob and tube wiring. Upgrading protects your investment and your family. We test circuits with digital multimeters. This verifies proper grounding before we restore power. Each room gets updated with properly rated breakers in your panel. You get safer outlets, better capacity, and improved reliability.

Common Questions

Residential Electrical FAQs

Common questions from Triangle homeowners about residential electrical services. Don’t see yours? Call us directly — we’re happy to help.
How long does a typical replacement take?
Most single-family homes take three to five days. Time depends on square footage and how much knob and tube remains active. We work room by room to minimize disruption. You will have power in unaffected areas while we upgrade each circuit. Larger Victorian homes with multiple stories may take a full week. We provide a detailed timeline after our initial inspection.
We use fish tape and flexible drill bits to run new wire through existing wall cavities whenever possible. Strategic access holes might be needed at junction points or where walls lack pathways. We keep openings small and patch them with drywall ready for paint. Our goal is minimal invasiveness while ensuring code-compliant installations throughout your home.
Yes, we can prioritize high-use areas like kitchens and bathrooms first. However, insurance companies often want confirmation that all knob and tube is deactivated, not just replaced in some rooms. We will cap and disconnect any remaining old wiring so it is completely dead. Phased approaches work well for budget planning as long as safety is not compromised.
We pull the electrical permit from your local building department before starting work. The permit fee typically runs between $150 and $400 depending on your municipality and project scope. An inspector visits after we finish to verify proper wire sizing, grounding, and junction box installation. We schedule the inspection and meet the inspector on site. You receive signed-off paperwork for your records.
Knob and tube lacks an equipment grounding conductor. This means no protection against shock hazards. The cloth insulation deteriorates over decades, exposing bare copper wire. It was not designed for modern loads from microwaves, computers, and multiple devices running simultaneously. Insurance companies view it as a fire risk and often refuse coverage. Building codes prohibit it in areas with insulation.

Pricing depends on your home’s size, how much knob and tube remains active, and wall access difficulty. Average costs range from $8,000 to $15,000 for a complete replacement in a 1,500 square foot home. Partial replacements or single-circuit updates cost less. We provide free estimates after inspecting your electrical system. Many homeowners recover costs through lower insurance premiums and increased property value.
