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 was very happy with my recent experience working with Chesapeake electric. They quickly resolved two issues I was having in my home and then also completed a project I have wanted to have done the following day. They were timely, professional, competent, and there was great communication with updates related to their arrival time. It was very easy to schedule both appointments. Paul, Logan, and Ethan were great and I was very impressed.
Jessica King

Called and spoke to someone right away. She was new and still learning but she was polite and able to help me right away. We needed an outside outlet added at the office. They came out the next day. Introduced themselves to everyone and got right to work. They did an amazing job. They were quick and efficient. The new outlet looks great and works very well. I had emails and texts about the appointment and reminders and updates on when they would arrive. The entire experience was above and beyond.
Amanda Morales

Was extremely happy that Chesapeake Electric was able to help in an emergency. I called other companies and was told I had to wait 1-2 weeks. Zachary from Chesapeake Electric responded and was on my doorstep one hour later. Very professional and knowledgeable. I am happy that my home is safe.
Nancy Bass

We are super happy with the work done by Ian and team at Chesapeake Electric. Our condo had no ceiling lights and was very dark, so we had Chesapeake wire and install lights in our living space and bedroom. They also installed a chandelier, some new bathroom fans, and a ceiling fan in the office. Everyone was super professional, on time, and they cleaned up really thoroughly after they were finished. They also did their best to mitigate drywall damage, which I appreciate. We are very, very happy with the results, and we have so much more light! We highly recommend Chesapeake Electric and will definitely use them again if we need any more electrical work done.
Jennifer Buck

These guys were fantastic. After calling 2 other electricians with no success, I called Chesapeake Electric. They came in less than 4 hours and right on time! The nicest people and super professional! They provided a detailed explanation of the problem and fixed it quickly at a reasonable price. I would highly recommend them to anyone.
