Nick was very professional from the start to finish. We did an electrical panel upgrade and everything went as expected. They left the place clean, which I appreciate a lot.

Nick and his crew were excellent! Reliable, responsible, highly skilled, knowledgeable, neat and well-priced. They had a job that turned out to be more complicated than they thought and were extremely conscientious about making sure they only made small holes in the walls when it was absolutely necessary. (A friend had a similar job done and the crew made a much messier and more expensive job of it) They delivered what they said and were always on time and responsive to calls and questions.

Our experience with Nick and his team at Greenway was beyond incredible. They had to do a ton of work, from installing a security system to moving an electric panel. Everything was done professionally, kindly and to the T with detail. I cannot thank them enough for their work. They were truly here from 7:30 AM to 5:30 PM some days making sure everything was right. Incredible guy, and will be sure to use him in the future. It's hard to find workers you can trust, but Nick and his team are the real deal. My sister is already looking forward to working with them later this year too.

We recently bought a house in Montclair and it had knob & tube wiring. We got a few estimates from different contractors but Greenways was the most detailed one . No surprises and while Greenway was there we added additional work, the prices for the additional work were fair since the crew was already there. Very nice workers, clean, neat and the holes they made were very small which brought the price of the painters down. The project manager Anthony was rigor to make sure we finished the job by the deadline so we wouldn't fall behind with the other contractor that needed to come back after Greenway was done. Passed all inspections without any problems and we are glad we went with them. Now days it is very hard to find reliable contractors. I would recommend Greenway to all my friends and family.

The first time I met Nick, the owner of Greenway Electric, he was working in my neighbor's house after Hurricane Sandy. I had connected a generator to my furnace to heat the house and was worried that I hadn't done it right. Nick was happy to take a look and help me. Since then I've done extensive electrical work to 3 houses and have used Greenway every time. Nick is also well-versed in lighting design and can offer suggestions for lighting options. Their work is excellent, the technicians are polite and conscientious and their prices are reasonable. I highly recommend Greenway.

I recently embarked upon the project of looking to find an electrician to remove Knob and Tube Wiring from my circa-1896 home. Of the four estimates I received Greenway's was by far the most comprehensive and detailed. Nick, the owner, spent a good deal of time examining the existing wiring and within a day had an estimate to me. We went with Greenway, and were delighted we did. The crew were prompt, efficient, polite, hard working, and conscientious. They did an outstanding job making the holes in the walls as small as possible and performing the comprehensive job in an efficient manner. The job Greenway did removing Knob and Tube Wiring was approved by the Town Inspector without a hitch. I highly recommend Greenway to anyone looking for a quality electrician. Nick is a consummate professional, delivering high quality work to his customers.

Knob and Tube Wiring Replacement Services

Knob and tube wiring poses significant safety hazards for residential electrical systems, characterized by a heightened risk of electric shocks and fire incidents. Consequently, it is imperative to consider its replacement. Even though knob and tube wiring has become outdated, it persists in homes constructed before 1940 and after 1880. If your residence still utilizes this wiring method, a thorough examination is warranted. Our electricians in New Jersey provide comprehensive solutions for replacing knob and tube wiring, ensuring affordability without compromising on safety. We conduct meticulous property inspections to identify the presence of knob and tube wiring and subsequently upgrade your system to align with contemporary safety standards.

Old Knob and Tube Wiring | What is knob and tube wiring?

Knob and tube wiring, once the standard in electrical installations, is now a relic of the past. But what exactly is knob and tube wiring? It’s an early form of electrical wiring, identifiable by its ceramic knobs and tubes, used extensively from the late 1800s until the 1940s. This leads to the question: when was knob and tube wiring used? It was most common in homes built before the 1950s.

Is knob and tube wiring safe? Generally, the answer is no. The lack of a ground wire in knob tube wiring and knob and tube wiring makes these systems less safe than modern wiring methods. What does knob and tube wiring look like? You’ll typically see white ceramic insulators (knobs) that support the wire and ceramic tubes that protect the wire as it passes through wood framing.

Why is knob and tube wiring dangerous? 

Upon discovering knob and tube wiring in their homes, our clients often approach us with concerns about their safety. The reputation of K&T wiring for its potential hazards has heightened these worries. While the presence of knob and tube wiring doesn’t immediately expose homeowners to the risk of electrical fires, it is crucial to acknowledge the substantial danger associated with this antiquated electrical system. There’s no need for immediate panic, but a comprehensive understanding of the potential risks is essential.

  • Knob and tube wiring doesn’t include a safety ground conductor
  • It is not safe for areas where there is moisture
  • It can easily be hidden under insulation
  • It may have become corroded, worn or damaged throughout the years
  • It doesn’t have a junction box
  • It has a limited power capability

At Greenway, we understand the intricacies of updating knob and tube wiring. Our professionals know how to replace knob and tube wiring, offering comprehensive solutions from assessing your current system to providing a detailed knob and tube wiring diagram for upgrades. Replacing knob and tube electrical wiring involves not just removing the old knob and tube wire but also installing a safer, more efficient system. We also tackle the complexities of knob and tube rewiring in homes that still have active knob wiring or knob and tube wiring.

Understanding how does knob and tube wiring work is key to our approach. The tube wire method lacks the grounding necessary in modern electrical systems, which is a major factor in our evaluation of whether is knob and tube wiring dangerous in your specific scenario. Our goal at Greenway is to ensure your home’s electrical system is not just safe and compliant with current standards, but also tailored to your home’s unique character.

Knob and Tube Breaker Box

Upgrading your home’s electrical system is crucial for safety and efficiency, especially if it still relies on a knob and tube breaker box. Originally, knob and tube wiring fuse boxes were the standard in the early 20th century, but today’s electrical demands far exceed what they were designed to handle. While a knob and tube electrical panel may carry a certain vintage charm, it’s important to ask: can knob and tube wiring be used with modern circuit breakers? The answer often leads homeowners to opt for a full upgrade. Replacing your old knob and tube panel with a modern breaker box enhances safety, meeting today’s stringent electrical codes and handling the increased load of contemporary appliances and devices.

Old House Wiring

Dealing with old house wiring can be challenging, particularly in New Jersey’s many historical homes. These structures often contain old electrical wiring types, including cloth-insulated wires or even the obsolete knob and tube systems. Understanding old wiring types is crucial for safe and effective upgrades. Types of wiring in old houses vary, but the common factor is that they are not designed for today’s electrical demands. Our team at Greenway specializes in deciphering old house electrical wiring, which can date back to the 1900s. Upgrading old home wiring types not only improves safety but also enhances your home’s functionality. Our expertise extends to interpreting old house wiring diagrams and seamlessly integrating modern wiring solutions while preserving the integrity of your vintage home.

What can you expect from our K&T replacement services in New Jersey?

Ensuring the safety of your home and family involves replacing your residence’s knob and tube wiring system. Greenway Electrical specializes in the removal of knob and tube wiring, upgrading your home to the latest and most advanced electrical system available. The duration of the replacement process depends on your home’s existing wiring configuration, ranging from a few hours to a few days. Though it might appear to be a significant timeframe, the resulting peace of mind and enhanced safety make it a worthwhile investment. Here is an overview of our knob and tube replacement process:

Knob and Tube Wiring Inspection

Our professional knob and tube replacement services ensure the safety and functionality of your electrical system. If you’ve identified knob-and-tube wiring in your home—recognizable by black cables wrapped around white or gray knobs and running through tubes of the same color, often found in basements where most exposed wires are located—it’s essential not to touch the wiring for inspection.

The first step in our process is to shut off the breaker to areas with exposed wiring and inspect from a safe distance for any noticeable damage, such as cracks along the knobs and tubes or frayed insulation. If damage is present or insulation surrounds the wiring, creating a potential fire hazard, it’s crucial to call a local electrician before proceeding.

Knob and Tube Wiring Replacement

Considering the limitations of knob-and-tube wiring in handling modern electricity demands, our experts advise unplugging most items connected to this wiring, especially those with high power consumption. The next phase involves spreading out outlet usage and limiting electronics to avoid strain and potential shorting. Surge protectors may still be used but with a principle of limiting to two electronics at a time.

The actual replacement process starts with the removal of existing wiring, a task strongly discouraged for anyone without proper training. Our licensed electricians use voltage meters to confirm power shutdown, ensuring safety. Cutting the wiring with appropriate tools and removing porcelain knobs without shattering them is done meticulously. When reaching tubes, the electrician may pull the wire through or decide to remove or leave the tubes based on recommendations.

At every step, our priority is your safety and the functionality of your electrical system. If you are looking for an electrical contractor in New Jersey who can efficiently replace your knob and tube wiring, Greenway is here to bring your home’s electrical infrastructure up to modern standards.
