What We Offer
If your home still has knob and tube wiring, it may be time to consider an electrical upgrade. At Plugged-In Electrical, we help homeowners identify outdated wiring, understand their options, and complete safe, code-conscious knob and tube remediation work with as little stress as possible.
Older wiring systems were not built for the electrical demands of modern life. Today’s homes rely on far more power for appliances, electronics, heating and cooling equipment, and everyday convenience. If your home still has knob and tube wiring, upgrading it can improve safety, support future renovations, and help give you peace of mind.
What Is Knob and Tube Wiring?
Knob and tube wiring is an older electrical system commonly installed in homes built roughly before the 1950s. It uses ceramic knobs to support wires and ceramic tubes to protect them where they pass through wood framing.
While knob and tube wiring was standard for its time, it was never designed for the power usage of today’s households. Over time, this wiring can become brittle, damaged, improperly altered, or overloaded by modern electrical demands.
Why Homeowners Replace Knob and Tube Wiring
Many homeowners choose knob and tube remediation for a few important reasons:
Safety
Many homeowners choose knob and tube remediation for a few important reasons:
Capacity for Modern Living
Knob and tube systems were installed long before homes had today’s kitchens, home offices, entertainment systems, EV chargers, and heavy appliance loads.
Remodeling and Insulation Issues
If you are remodeling, opening walls, or adding insulation, knob and tube wiring often becomes a major concern. In many cases, it should be addressed before other upgrades move forward.
Insurance and Real Estate Concerns
Some insurance companies are hesitant to insure homes with active knob and tube wiring, or they may require evaluation or replacement. It can also raise concerns during a home sale or inspection.
Signs Your Home May Still Have Knob and Tube Wiring
You may have knob and tube wiring if:
- Your home was built before 1950
- You have an older fuse panel or outdated electrical system
- Lights flicker or circuits feel overloaded
- You notice ungrounded outlets with only two prongs
- An inspector, electrician, or insurance company has flagged the wiring
- You have exposed wiring in an attic, basement, or crawlspace supported by ceramic knobs
Not every older home still has active knob and tube, and not every section of wiring may need the same solution. That is why a professional evaluation matters.
Our Approach to Knob and Tube Remediation
At Plugged-In Electrical, we take a practical, thorough approach. We know homeowners want honest answers, clear options, and quality work done right.
- Evaluation and Planning: We start by assessing the home, identifying where knob and tube wiring is still active, and determining how it fits into the rest of your electrical system.
- Scope Development: Every house is different. Some homes need partial rewiring in specific areas, while others need a more complete remediation plan. We create a clear scope of work based on your home, goals, and budget.
- Safe Replacement and Upgrades: We remove or permanently disconnect outdated wiring where appropriate and install modern wiring methods designed for current code requirements and real household use.
- Coordination With Other Work: If you are remodeling or opening walls, we can help coordinate the electrical portion so the project moves more smoothly.
What Knob and Tube Remediation May Include
Depending on the home, remediation may involve:
- Replacing active knob and tube wiring
- Installing new branch circuits
- Updating outlets, switches, and lighting feeds
- Adding grounded wiring where needed
- Reworking circuits for kitchens, bathrooms, and living spaces
- Panel upgrades if the existing service is undersized or outdated
- Correcting unsafe modifications tied into old wiring
Our goal is not to oversell work you do not need. It is to help you move from outdated wiring to a system that is safer, more reliable, and better suited for your home.
Is Knob and Tube Wiring Dangerous?
Knob and tube wiring is not automatically dangerous just because it is old. The concern is usually what has happened to it over time.
Problems often come from:
- Aging wire insulation
- Overloaded circuits
- Improper splices or handyman modifications
- Lack of grounding
- Insulation packed around wiring not intended for that condition
- Years of additions layered onto an outdated system
The safest next step is to have it professionally evaluated so you know what condition it is in and what should be done.
Should You Replace All of It?
Not always in one step. Some homes benefit from a full replacement plan, while others may start with the most critical areas first.
That depends on:
- How much active knob and tube remains
- The condition of the wiring
- Your renovation plans
- Insurance requirements
- The age and condition of the panel
- Your long-term goals for the home
We can help you understand whether a phased approach or a larger upgrade makes the most sense.
