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.

Extremely professional and expert service!Posted on Google Mark WagnerTrustindex verifies that the original source of the review is Google. Jeff Rubino and his team at JMR provide exceptional and intelligent service. I have worked with JMR Electric for many years. This year, they really went above and beyond. My wife and I had a huge roof leak at our three family house in Somerville. In the course of repairs, old knob and tube wiring was discovered. JMR worked with us, the Insurance company and Inspectional services so that we could complete the project quickly. They were very easy to work with and their work came in under budget.Posted on Google A- trainTrustindex verifies that the original source of the review is Google. Very professional and reasonable. Stayed within the budget and timeframe. Very satisfied would definitely recommend.Posted on Google William SimmonsTrustindex verifies that the original source of the review is Google. Had electrical work done at my house and could not be happier with the experience. They were professional, on time, and explained everything in a way that actually made sense. The quality of the work was excellent and they clearly take pride in what they do. It’s hard to find contractors that are reliable, communicate well, and leave the place cleaner than they found it, but these guys did exactly that. Fair pricing, honest work, and no headaches. I would absolutely recommend them to anyone looking for electrical work done right.Posted on Google Joseph ChartierTrustindex verifies that the original source of the review is Google.
