Knob & Tube Rewires

Knob & Tube Wiring Replacement — Protect Your Home and Family
If your home was built before 1950, there’s a good chance it still contains knob and tube wiring. While this was the standard electrical system of its era, knob and tube wiring is now considered outdated, potentially dangerous, and incompatible with the demands of modern living.
Having it replaced by a licensed electrician is one of the most important investments you can make in the safety and value of your home.
What Is Knob & Tube Wiring?
Knob and tube (K&T) wiring was commonly installed in American homes from the 1880s through the 1940s. It consists of single insulated copper conductors routed through ceramic knobs and tubes, with no ground wire. While it was adequate for the electrical loads of that time, today’s homes use far more power — and K&T simply wasn’t designed to handle it.
Why It Needs to Go
- It’s a Fire Hazard: The rubber insulation becomes brittle and cracks over time, exposing live conductors. Contact with insulation or wood framing dramatically increases the risk of an electrical fire.
- No Ground Wire: K&T has only two conductors (hot and neutral). Without a ground, your appliances and electronics have no fault protection, leaving you vulnerable to shock and equipment damage.
- Incompatible with Modern Loads: High-draw appliances, HVAC systems, and home offices overload the system, accelerating insulation breakdown.
- Insurance Issues: Many insurance companies will refuse to cover homes with active K&T or will charge significantly higher premiums.
- Fails Home Inspections: K&T is a major red flag that can derail home sales and lower your property value.
- Not Up to Current NEC Code: Knob and tube wiring does not meet current National Electrical Code (NEC) requirements and cannot legally be extended or modified.
“Proactive replacement is always safer and more affordable than emergency repairs or fire restoration. Don’t wait until there’s a problem.”
What Replacement Looks Like
Our licensed electricians will remove your existing knob and tube wiring and replace it with modern, NEC-compliant wiring throughout your home. This includes:
- Properly grounded circuits.
- Updated outlets and switches.
- A new or upgraded electrical panel if needed.
We work carefully to minimize damage to walls and ceilings during the rewiring process, and we handle all necessary permits and inspections so you have full documentation that the work was completed to code.
Don’t Wait Until There’s a Problem
Knob and tube wiring doesn’t always show visible warning signs before it fails. By the time you notice flickering lights or tripped breakers, the damage may already be done.
