Knob and Tube Wiring Replacement in Alexandria, TN
Knob and tube wiring was standard practice generations ago, but it wasn't designed for modern insulation, appliance loads, or grounded devices — and many insurance carriers won't cover a home that still has it. Center Hill Electric Co. replaces knob and tube wiring in Alexandria, TN's older homes and farmhouses with modern, grounded circuits.
We understand the character of DeKalb County's historic homes and work carefully to modernize the wiring without unnecessary damage to plaster, trim, or original woodwork.
Knob & Tube Wiring Replacement You Can Rely On in Alexandria, TN
Knob and tube systems lack a ground conductor, use rubber insulation that becomes brittle with age, and were never designed to have insulation packed around them — a major fire risk in homes that have since been insulated for energy efficiency. Replacement isn't just about compliance, it's about removing a genuine and growing fire hazard.
We plan each rewiring project room by room, running new grounded copper wiring through existing chases wherever possible to minimize wall and ceiling openings, and patching any access points we do need to make.
Because knob and tube replacement often happens in phases, we can prioritize the highest-risk circuits first — kitchens, bathrooms, and areas with insulation already installed around old wiring — while planning the full rewire around your budget and timeline.

Frequently Asked Questions
Why won't my insurance company cover a home with knob and tube wiring?
Insurers consider knob and tube a significant fire risk, particularly where it's been covered with insulation, and many carriers now decline or heavily surcharge policies until it's replaced.
Do you have to open every wall to replace knob and tube wiring?
We minimize openings by routing new wire through existing chases and accessible spaces wherever possible, though some limited wall or ceiling access is usually necessary.
Can knob and tube replacement be done in phases?
Yes, we regularly phase this work, starting with kitchens, bathrooms, and any areas where old wiring is buried in insulation.
How do I know if my house still has knob and tube wiring?
Look for ceramic knobs and tubes in an unfinished attic or basement, or ask us to inspect during a free estimate — it's often hidden behind finished walls.
Will replacing the wiring damage my home's original trim or plaster?
We take extra care in historic homes and coordinate patch work so the visual impact is kept to a minimum.
