Knob-and-tube wiring was standard through the 1940s — but it has no ground wire, brittle cloth insulation, and is routinely flagged by insurers and home inspectors today. We remove it completely and replace it with a grounded, code-current system.
- Full removal of active knob & tube circuits
- Grounded, code-compliant rewiring
- Insurance & inspection documentation
- Permit & inspection handled
Knob & Tube Replacement
Why It Matters
Why Knob & Tube Wiring Needs to Go
Knob-and-tube wiring has no ground wire, brittle rubber-cloth insulation that degrades with age, and was never designed to carry the load of today’s appliances, HVAC systems, or home electronics. Many insurance companies now decline or non-renew policies on homes that still have active knob-and-tube circuits.
We trace every knob-and-tube run in the home, remove it completely, and replace it with modern grounded cable or conduit — sized to current code and documented for your insurer or the home inspector who flagged it.
“Insurance flags it, inspectors flag it — we’re the ones who actually fix it, not just patch around it.”
What’s Included
A Full Replacement, Not a Patch Job
Every knob & tube replacement is planned around tracing every run in the home and closing it out with proper documentation.
Complete Circuit Tracing
We trace every active knob-and-tube run in the home before any wiring comes out — nothing gets missed or left live behind a wall.
Full Wiring Replacement
Every knob-and-tube circuit is replaced with modern, grounded cable sized for current and future loads.
Grounding & GFCI/AFCI Compliance
New circuits are properly grounded and protected to current code, including GFCI and AFCI where required.
Room-by-Room Scheduling
Work is sequenced room by room so the rest of the home stays livable while the rewire is in progress.
Outlet & Switch Replacement
Every outlet and switch tied to knob-and-tube circuits is replaced and updated to current code.
Permit, Inspection & Documentation
We pull the permit, schedule the inspection, and provide documentation your insurer or inspector can rely on.

Final Walkthrough
You get a full walkthrough plus documentation for your insurer or inspector — proof the knob-and-tube is gone.
FAQ
Common Questions About Knob & Tube Wiring Replacement
How do I know if my home has knob & tube wiring?
Homes built before the 1950s often have it. Look for ceramic knobs and tubes in the attic or basement, or ask your electrician to check during a free assessment — it’s not always visible without opening walls.
Will replacing knob & tube wiring lower my insurance costs?
Many insurers decline or non-renew policies over active knob-and-tube wiring. Replacing it can restore standard coverage — we provide documentation your insurer can use, though rates are set by your carrier.
Do I have to replace all of it at once?
We can phase the work by room or circuit if needed, but any wiring left in place should be inactive and clearly documented — partial rewires need to be planned carefully.
Will you need to open up my walls?
In most cases, yes — some drywall or plaster access is required to pull new wire. We plan the work to limit openings and patch what we access as part of the job where agreed.
How long does a knob & tube replacement take?
It depends on the home’s size and how much of the wiring is still active. We’ll give you a specific timeline after the assessment.
