the perfect solution to your wiring problems

Skillfully Replacing Knob And Tube Wiring In Your Home

After completing the final paint touch-ups on your home, you are ready to put it on the market. However, one last run-through with your real estate agent turns up an unanticipated problem: your home has a knob and tube wiring. This first generation electrical wiring method is not only obsolete in today’s day and age, but could be a potential safety hazard should something go wrong. Anytime a home is sold, any K&T wiring has to be removed per the buyers’ contract and most electricians won’t touch the stuff because they don’t have the skillset to remediate the problem correctly. Fortunately, Chesapeake Electric is up for the challenge! Our experienced team is led by a Master Electrician whose thoroughness and knowledge of knob and tube remediation provides the perfect solution to your wiring problems.

What is knob and tube wiring?

Knob and tube wiring was an early standardized electrical method in North American buildings from 1880 to the 1940s. It is very common in the historical districts of Annapolis, Baltimore, Ellicott City, and Washington, D.C. K&T wiring consists of insulated copper conductors that pass through drilled holes in lumber framing that are protected by porcelain insulating tubes. These tubes are supported along their length by nailed-down porcelain knobs.


Common Problems With Knob & Tube Wiring

While the original installation of knob and tube wiring is at times superior to modern Romex wiring and the porcelain components have an almost unlimited lifespan, there are several disadvantages to this dated wiring method:

  • Image
    Though not inherently dangerous, knob and tube wiring is not permitted in any new construction due to the fact that it can be a fire hazard in buildings where insulation envelops the wiring. Insulation cannot be blown or laid on this wiring.
  • Image
    K&T is also an ungrounded electrical system, which means it cannot be used with 3-prong appliances. Without a grounding wire, there is a higher risk of electrical fires and damage to sensitive equipment.
  • Image
    In addition, most homeowners’ insurance policies do not cover electrical hazards in homes where knob and tube wiring is found, increasing your out of pocket expenses should your home ever have an electrical problem.

What Our Happy Customers Are Saying


I hired Chesapeake Electric to convert 7 recessed lights to LED and hang a new light fixture. Kevin was my technician. Someone else was with him but I’m sorry I don’t remember his name. Both were very well spoken, friendly and knowledgeable. Kevin explained the work that would be done and helped me decide on the color temperature and brightness of the LED lights. I was a little indecisive but Kevin was patient with me. Kevin did an inspection of my home and found that the service panel outside was badly damaged. He recommended that it be replaced and explained why. He came back the next day and repaired it and swapped out two breakers. Overall, I was very pleased with the work that was done. I especially appreciated Kevin’s willingness to take the time to explain the work so that I could understand what would be done. I will definitely use this company again.

Needed a next day "simple" outdoor fixture wired. Turned out to be not SO simple as load bearing beam blocked the preferred path. Zach adjusted on fly and job completed in time to mesh with other contractors working on project. Reasonable pricing for all needed materials and labor cost$ on 1Day turnaround. Fast scheduling response, great app and tech on backend.
