Knob Tube Remediation

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:

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.

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.

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.

Subject: Commendation for Exceptional Service – Chesapeake Electric and ServiceMaster Team

Dear Mr. Deshaies and CO.,

I am writing to formally express my family’s sincere gratitude for the exceptional service and support we received following the house fire at our home.

During an incredibly difficult and stressful time, Chesapeake Electric, under the ownership of Mr. Deshaies, provided outstanding service, professionalism, and dedication. I would especially like to recognize Head Master Electrician Matt for his extraordinary hard work, long and tedious hours, and the kindness and professionalism he consistently demonstrated throughout the process. His expertise, personal involvement, and willingness to go above and beyond were invaluable. In particular, we are deeply grateful for his assistance in ensuring the electrical work was completed properly, for helping us obtain the correct invoices, and for providing the explanations necessary to support our insurance claim. His continued support in addressing the full electrical panel replacement, house rewiring, and additional secondary damage related to environmental causes was truly exceptional.

I would also like to extend our heartfelt appreciation to Mr. Deshaies and his team for the remarkable restoration services they provided. From the very beginning, Chesapeake Electric's prompt response, timely and flexible scheduling, and close attention to detail gave us reassurance during an emergency situation caused by a freak event of nature. They quickly arranged a comprehensive damage assessment, and their team worked diligently to restore our home.

Their efforts included bringing in expert electricians, thoroughly inspecting and diagnosing all issues and related systems, and conducting a meticulous top-to-bottom, floor-to-ceiling professional electrical home renovation service. They successfully removed the damaged items, cables, wires, and all pertinent necessities and went above and beyond to help ensure our home was safe and that quality newly installed and properly tested lines and equipment were restored for our family’s comfort and well-being.

Mr. Deshaies themself, the owner of the company came out and spent over 12 hours during the initial cause, diagnosis, assessment, and worked hand-in-hand, rolling up their sleeves to assist Matt and their other team members in everything electric. They personally went back to their warehouse to save time and pick up all necessary equipment, inventoried, and laid the foundation for a meticulous insurance quote and detailed invoicing to include all necessary before and after the damage pictures. They wrote a personal professional email to explain to the insurance company the gravity and necessity of the situation and all the work that was being completed to include the secondary issues arising from the fire, to ensure we were 100% covered and taken care of.

Both Chesapeake Electric CO., Mr. Deshaies and his team demonstrated an exceptional level of professionalism, compassion, and commitment during one of the most challenging times our family has faced. Their hard work and care made a tremendous difference, and we wanted to ensure their efforts were formally recognized and shared with leadership.

Please extend our deepest thanks and appreciation to everyone involved.

Sincerely,

Mr. Dvir Samet

Chesapeake Electric is the only company I will use when it comes to all of my electrical needs. This is based on Chesapeake’s reliability, integrity, fair pricing, honesty, and quality workmanship/performance of their techs. Today I want to take the time to acknowledge Gary Howe, Alec Vazquez and Dan Sarnf. It is people like them who keep Chesapeake Electric #1 on my list when it comes to all of my electrical needs. They worked extremely hard for three consecutive days, explaining everything they were doing along the way in layman terms for me to understand. They are truly an asset for your company and another reason why I always recommend Chesapeake to anyone having electrical needs. Also, a shout out to Casey Wumer who did my yearly inspection as well as giving me a thorough and honest recommendation for what needed to be done. And let us not forget Jackie back in the office who handles every call with respect and class. All of these people mentioned are truly assets to your company.
