Why You Should Replace Knob & Tube Now
- Fire Hazard: Old wires have deteriorated insulation and no grounding.
- Insurance Issues: Many carriers deny coverage or charge high premiums.
- Unsafe for Modern Loads: Today’s appliances can overload old wiring.
- Hurts Home Value: Inspectors, lenders, and buyers all flag this issue.

If your home was built before 1950, there’s a high chance knob and tube wiring is still present — even if it's hidden behind walls. Contact our expert team today to schedule a free in-home evaluation or request a quick online estimate.
Frequently Asked Questions
Q: Do I really need to replace my knob and tube wiring?
A: If it’s still active, yes. Even if it “still works,” the wiring is not grounded, wasn’t designed for modern electrical loads, and is often unsafe by today’s standards.
Q: How long does a full replacement take?
A: Most projects take 25 to 30 days, depending on the size and layout of your home.
Q: Will you patch the walls after rewiring?
A: Yes. We handle patching and repairing all walls and ceilings that are disturbed.
Q: Are you licensed, bonded, and insured?
A: Yes. We are fully licensed, bonded, and insured in the state of California. We also name all property owners as additional insured on our general liability insurance policy.
Q: Can I live in my home during the work?
A: In most cases, yes. We plan the work in phases to minimize disruption.
