If your older Cleburne home still has knob and tube wiring, it is running on a system that predates grounding, insulation contact rules, and modern electrical loads. Dugger Electric safely replaces knob and tube wiring in Cleburne with modern, grounded copper circuits that meet current code and restore your home’s insurability. Our licensed electricians (TECL #27539) plan the work carefully, remove or retire the old wiring, and bring every circuit up to today’s standard. Estimates are free across Johnson County, and the project can be financed through First Financial Bank. Call (817) 678-1289 to make an older home safe.

What Happens During Cleburne Knob and Tube Replacement

  • We inspect the house to map how much knob and tube is still live, because in most of these homes some of it was abandoned decades ago.
  • We plan a phased replacement that keeps the house occupied and opens plaster only where the framing leaves no alternative.
  • We run new grounded copper circuits and safely retire the old ungrounded conductors rather than leaving them energized behind the walls.
  • We replace two-prong receptacles with grounded devices and add GFCI and AFCI protection where code requires it.
  • We tie the new circuits into a properly sized panel, carry the permits, and pass the inspection that your insurer will want to see.

How Much Does Knob & Tube Replacement Cost in Cleburne?

Replacing knob and tube wiring usually runs about $12,000 to $35,000, or roughly $8 to $17 per square foot depending on the home’s size and access. The knob and tube replacement cost guide lays out the drivers. Homes with attic and crawlspace access and an already-adequate panel cost less than those needing walls opened and a service upgrade.

Dugger Electric: Your Local Knob & Tube Replacement Resource

Since 1974, Cleburne families and business owners have called Dugger Electric when historic homes need obsolete knob and tube wiring safely replaced. As a family-owned business and proud member of the Johnson County Builders Association and Cleburne Chamber of Commerce, we have the specialized expertise to navigate local historic properties, treating your older home with the craftsmanship it demands. Call (817) 678-1289 to book an evaluation of your vintage wiring.

  • Is knob and tube actually dangerous? It has no ground, the insulation goes brittle with age, and it runs hot under modern attic insulation it was designed to be clear of. Those three together are why insurers treat it the way they do.
  • Does all of it have to go at once? Not necessarily. We can phase by area, though full replacement is usually the goal, because partial systems are what insurers keep flagging.
  • Will it affect my insurance? Frequently. Many carriers surcharge or decline homes with active knob and tube, so replacement often changes the policy conversation entirely.
  • How do you handle plaster walls? Carefully, and with as few openings as the framing allows. Plaster does not patch like drywall, so we plan the routes to minimize what has to be repaired afterwards.

Knob-and-tube rarely stands on its own anymore. Insurers flag it, and it can’t be grounded the way modern circuits are. Replacing it usually happens as part of a local whole-home rewiring, and these houses nearly always need an electrical panel upgrade to anchor the new grounded runs. Once the wiring is up to date, surge protection finally has something safe to work with.

You may be living with knob and tube wiring if several of these are true:

  • The house was built before roughly 1950 and has never been rewired.
  • There are ceramic knobs and tubes with cloth-covered conductors in the attic or basement.
  • Most or all of the outlets are ungrounded two-prong receptacles.
  • An insurer has flagged the wiring, or declined to write the policy.
  • Breakers or fuses trip often and the whole system feels stretched.
Call (817) 678-1289 and we will map how much of it is still live.

Knob and tube wiring served its era well, but it has no place in an insured, modern household. Dugger Electric replaces these outdated systems across Cleburne and Johnson County with grounded, code-compliant circuits, pacing the work so you can comfortably stay in your home.

Three Knob & Tube Risks We Resolve in Cleburne Homes

Cleburne’s older neighborhoods, especially the blocks near the historic downtown, still hold houses with original knob and tube wiring in the walls. We evaluate them across Johnson County regularly. Here are the three risks the system carries and what replacement resolves about each.

Knob and tube was installed without an equipment ground, which is why these houses are full of two-prong receptacles and offer no fault path for people or electronics. No adapter creates a ground where none was ever run. We replace the ungrounded circuits with modern grounded copper and fit three-prong, GFCI-protected receptacles, so the house finally has the fault path everything plugged into it assumes already exists.

The cloth and rubber insulation goes brittle with age and cracks away from the wire, and the system runs hotter still under blown-in attic insulation it was designed to stay clear of. That combination is exactly why insurers treat it the way they do. We retire the aged conductors and run new wire rated for the conditions it will actually live in.

Knob and tube systems were sized for a few lights and a couple of outlets per floor, not central air, a full kitchen, and everything a household charges overnight. They run chronically overloaded, and splicing modern cable onto them compounds the problem rather than relieving it. A full replacement adds enough properly sized grounded circuits for how the home is used now, which ends the overload and brings the whole system to code.
