Knob and Tube Removal Newton, MA
Safe. Code-Compliant. Professional.
If your home still has knob and tube wiring—also known as old cloth wiring or “those porcelain thingies”—it’s time to bring your electrical system into the modern age. Knob and tube (K&T) wiring was standard in homes built from the late 1800s through the 1940s, but it simply isn’t equipped to handle today’s electrical demands.
Our licensed Newton electricians at Castle Electric specialize in safe, efficient knob and tube removal, helping you protect your home, satisfy insurance requirements, and prepare for future upgrades like new insulation or renovations.
Say goodbye to the risks associated with knob and tube wiring and embrace a safer, more reliable electrical system with this specialized electrical safety service. Call us today!
Book Now Book NowWhy Knob and Tube Wiring Is a Problem
Knob and tube wiring isn’t just outdated—it’s unsafe in today’s conditions.
- Ungrounded circuits: They don’t trip breakers like modern systems, creating shock and fire hazards.
- Hidden deterioration: Old cloth and rubber insulation breaks down, leaving exposed live wires.
- DIY modifications: Over the years, homeowners often spliced lamp cords or wrapped frayed areas with tape—dangerous shortcuts that can spark or overheat.
- Insurance limitations: Many carriers won’t insure a home with live K&T wiring.
If you’ve noticed flickering lights, two-prong outlets, or electrical smells, your home may still be relying on an outdated system.
For All Your Electrical Safety Needs
How to Tell if You Have Knob & Tube Wiring in Your Newton Home
Think your home might still have old wiring? Here’s how to spot the telltale signs:
- Porcelain “thingies.” Look in your basement or attic for small white or tan ceramic knobs and tubes nailed to joists—these are the original supports for early wiring systems.
- Old black or cloth-covered wires. Knob & tube often used black fabric or rubber insulation that looks frayed or dusty today.
- Push-button light switches. If some of your switches look like vintage push buttons, that’s a good clue your house still has early-century electrical work.
- Two-prong outlets. Homes without the third grounding hole typically have ungrounded circuits that trace back to K&T wiring.
- Historic construction. Homes in Newton built before 1950—especially those that haven’t had a major electrical renovation—commonly still have partial knob & tube systems hidden behind walls or ceilings.
Not sure what you’re looking at? Snap a quick photo in your basement or attic and send it to Castle Electric. Our licensed electricians can identify old cloth or porcelain wiring right away and let you know if it’s still live.
Is Replacing Knob & Tube Wiring in Newton Worth It?
In a word—yes. Upgrading outdated knob & tube wiring is one of the smartest improvements a Newton homeowner can make. While every house is different, here’s why the investment pays off:
- Safety first: Modern wiring includes a dedicated ground, preventing shocks and drastically reducing fire risk.
- Insurance approval: Most insurers will not write or renew policies on homes with live knob & tube circuits. Replacing the wiring restores coverage options and can even lower premiums.
- Energy efficiency: Once the wiring is updated, you can safely add wall or attic insulation—something you can’t do with active K&T.
- Home value: Buyers (and inspectors) see new wiring as a huge plus, and documented upgrades often raise resale value.
- Peace of mind: No more worrying about brittle insulation or overloaded outlets; your electrical system will finally meet today’s code and lifestyle needs.
Castle Electric provides transparent pricing after a thorough inspection, so you know exactly what to expect—no surprises, no upsells, just safe, code-compliant wiring that protects your family and your investment.
Why Homeowners Call Castle Electric for Knob & Tube Removal
There are two common scenarios when homeowners in Newton reach out to us:
Scenario 1: Home Sale or Insurance Requirement
The other common call we get is from homeowners or buyers dealing with insurance or real estate transactions.
- Home inspections often reveal knob and tube wiring, which can delay closings.
- Insurance companies frequently refuse to insure or renew policies on homes with active K&T wiring.
- Buyers and sellers turn to Castle Electric to replace it quickly, professionally, and with documentation that satisfies both insurers and inspectors.
If your report mentions “old black wiring,” “cloth-wrapped wire,” or “push button switches,” those are red flags that your home likely has original knob and tube circuits.
Scenario 2: Preparing for Insulation or a Mass Save Visit
If you’re moving forward with a Mass Save assessment or insulation project, you’ll need confirmation that your home is free of any live knob-and-tube wiring.
Castle Electric handles that from start to finish. We trace every circuit to pinpoint older wiring, update anything that’s still active, and replace it with safe, modern lines. When everything is cleared, we provide the approval your insulation contractor needs so the project can continue without safety concerns.
Mass Save and Electrical Safety
If you’re planning to participate in the Mass Save energy-efficiency program, electrical safety comes first. Before an insulation contractor can install new materials, the home must be verified free of live knob & tube wiring.
That’s where Castle Electric comes in. We frequently partner with Mass Save-certified contractors to ensure your project meets all safety and program requirements:
- Electrical mapping and verification: Our electricians inspect every accessible area to confirm whether knob & tube wiring exists or is still energized.
- Safe disconnection or full replacement: If live circuits are found, we remove or rewire them to current Massachusetts code.
- Documentation for Mass Save: Once the wiring is safe, we sign the official clearance form your insulation company needs to proceed.
Upgrading your wiring before adding insulation isn’t just a box to check—it’s essential protection against overheating and fire hazards.
Thinking of booking a Mass Save audit? Call Castle Electric first. We’ll make sure your home is ready for insulation and that every wire behind the walls is safe, grounded, and up to code.

“Our 99 year old father had a complete power failure. Castle came out immediately and within two days replaced every wire and put in a new electrical panel in a new location. It was amazing that they were out to his house immediately and replacement was done without a hitch. The wiring inspector commented on what a great job they did. It was a huge job and it was a really difficult situation as my father would not leave the house. We are so grateful to Castle. Not considering the quality of work alone, they were kind and considerate of a very old man. Thank you Castle Electric and we highly recommend your services.”
