Owning one of Stoneham’s beautiful, historic homes comes with a sense of pride and a connection to our community’s past. That classic architecture is a treasure, but preserving that treasure means tending to its oldest systems. One of the most critical is the electrical wiring. Many homes built in a bygone era still rely on knob and tube wiring, a system that, while once effective, now poses serious risks in a world filled with modern technology. For today’s homeowner, living with this old wiring can create a quiet, persistent worry about safety. JMR Electric is Stoneham’s dedicated local expert, committed to protecting families by performing professional knob and tube removal and replacement. A complete system upgrade offers peace of mind, a profound increase in safety, and an electrical foundation ready for all of today’s demands.
To make the best decision for your home, you first need to understand what is hidden behind your walls. Knob and tube (K&T) was the go-to method for wiring houses from the 1880s through the 1940s. Its design is quite different from what electricians install today, and its components are very distinct.
You can often spot K&T wiring in unfinished areas like basements, crawlspaces, or attics. You will see individual electrical wires protected by a black or white rubberized cloth sheath. These wires are meticulously routed through porcelain knob and tube insulators. The white, spool-like ceramic knobs hold the wires securely alongside wooden joists, while the longer ceramic tubes act as protective sleeves where wires must pass through the wood framing. A defining feature of this knob and tube electric system is the separation of the hot and neutral wires, which run parallel to each other. The most critical difference, from a modern safety standpoint, is its complete lack of a ground wire. Its amperage capacity is also extremely limited, making it completely unsuitable for the power needs of a contemporary household.
A home with knob and tube wiring might not show any immediate signs of trouble, but the risks are substantial and grow with each passing year. Being aware of these specific hazards is vital for any responsible homeowner. For anyone considering an appointment to remove knob and tube wiring, understanding the reasons behind the recommendation is paramount.
Replacing a home’s entire nervous system is a major project. With over 14 years of experience, JMR Electric has refined a careful, homeowner-focused process to make the experience as straightforward as possible. Our knob and tube wiring services are built on a foundation of safety, efficiency, and respect for your home.
The surest way is a visual inspection of an unfinished basement, crawlspace, or attic. Look for the distinct white ceramic knobs and tubes holding wires to and through the wooden joists. The presence of only two-prong outlets throughout an older home is another strong indicator.
To satisfy insurance requirements and for genuine safety, all active knob and tube circuits should be completely replaced. Wiring that is no longer part of a live circuit can sometimes be safely abandoned in place, but all electrical current should be running through a modern, grounded system.
The project timeline is shaped by the size of your house and how much of the wiring needs replacement. A typical home can take from a few days to a couple of weeks. We provide a clear and realistic timeline with our written estimate.
The cost is specific to each home, depending on its size, the accessibility of the wiring, and the number of fixtures and outlets. We provide free, no-obligation estimates to give you a precise and reliable cost for your project.

Will definitely use them again!Posted on Google Roseanna CutiettaTrustindex verifies that the original source of the review is Google. Two professional, hardworking young men arrived at my house promptly, insisted on taking off their salty icy boots to not track it through the house, and then worked collaboratively and methodically to solve my problem. They even explained what was wrong and answered my superfluous questions kindly. JMR Electric should be proud.Posted on Google Joe HTrustindex verifies that the original source of the review is Google. Guy and the team worked effectively and transparently to add the new circuit to my basement. It was nice to have everything be up front and transparent and to know what to expect. I recommend working with themPosted on Google wesley donohoeTrustindex verifies that the original source of the review is Google. We've used JMR Electric for multiple projects around our house and they've been fantastic every time. Guy has done all our work from fence lighting installation, fixing indoor lighting throughout the house, outdoor camera installation, and repairing all our outdoor outlets. What sets them apart is how they operate. They're fast to respond and schedule, the quality of work is excellent, and they always walk us through different options and recommendations before starting anything. No surprises, just clear communication and great results. We're big fans of Ed and his entire team. We will keep calling them for any electrical work we need.Posted on Google Tom AngeloTrustindex verifies that the original source of the review is Google.
