KNOB AND TUBE REPLACEMENT.

Knob & Tube Rewiring

Knob-and-tube wiring was standard in homes built before 1950. It has no ground wire, no protection for modern appliances, and becomes a genuine fire hazard when disturbed or covered with insulation. Hawkins Electric specializes in knob-and-tube replacement throughout Minneapolis, St. Paul, and the Greater Twin Cities — from targeted section removal to full home rewiring, performed by licensed electricians with permits and inspection at every step.

If your home was built before 1950, there's a good chance it still has some knob-and-tube wiring. The system gets its name from the ceramic knobs that hold wires to framing and the ceramic tubes that protect wires passing through joists. It was well-engineered for its time — but that time was a century ago, when homes had a fraction of today's electrical load.

The core problems with knob-and-tube in modern homes come down to three things: it has no ground wire (meaning your appliances and electronics have no fault protection), it was never designed for insulation contact (attic insulation packed around knob-and-tube wiring is a documented fire hazard), and it's been in service long enough that connections have loosened, insulation on the wires has become brittle, and amateur modifications have compromised the original installation.

Insurance companies have taken notice. Many carriers will not write or renew policies on homes with active knob-and-tube wiring, or they'll require documentation of its condition. If you're buying or selling a home with knob-and-tube, a licensed electrical inspection is almost always required.

At Hawkins Electric, we start with a thorough assessment. We map where the knob-and-tube is, evaluate its condition, and look for the most common problem areas — junction boxes that were opened and modified, sections buried under insulation, circuits that were extended with modern wire. From there, we give you an honest picture of what needs to be done and what it will cost.

For many homes, a full rewire is the right answer. For others, targeted replacement of the most problematic sections — combined with a panel upgrade — achieves the same safety outcome at a lower cost. We'll tell you which applies to your situation.

We serve older homes throughout Minneapolis, St. Paul, Blaine, Lino Lakes, White Bear Lake, Roseville, Columbia Heights, Northeast Minneapolis, South Minneapolis, and communities across the Greater Twin Cities where pre-1950 housing is most common.

When homeowners search for knob and tube replacement near them, the most important factor is working with a licensed electrician who has hands-on experience with older homes — not a general contractor who subcontracts the work or a handyman who can't pull permits. Every knob-and-tube replacement we perform is completed by state-licensed journeyman and master electricians, permitted with the local jurisdiction, and inspected before we close any walls. You get a paper trail that satisfies your insurance carrier, protects you at resale, and proves the work was done to code.
