Knob and Tube Removal Weston, MA
Safe. Code-Compliant. Professional.
If your Weston home still has knob and tube wiring, sometimes called old cloth wiring, or those little porcelain knobs you see fastened to joists, it is probably time to update your electrical system. Knob and tube was common in homes from the early 1900s, but it is not built for the amount of electricity families use today.
Our licensed Weston electricians at Castle Electric specialize in removing knob and tube safely and carefully. Homeowners call us to protect their property, satisfy insurance requirements, and get their houses ready for upgrades like insulation, renovations, or the addition of new lighting and outlets.
If you are ready for a safer and more dependable electrical system, we can walk you through the whole process. Give us a call when you are ready to start your electrical safety journey.

Book Now Book NowWhy Knob and Tube Wiring Is a Problem in Weston
Knob and tube wiring may look simple, but it poses several safety concerns in today’s homes.
- Circuits are ungrounded, which means they cannot protect against shocks the way modern wiring can
- The insulation that once protected the wires dries out and crumbles, exposing live wire
- Many older homes have had years of makeshift repairs that create loose or unsafe connections
- Some insurance companies will not insure a home with active knob and tube
If you have flickering lights, warm outlets, or a light electrical odor that comes and goes, you may still have older wiring in use.
For All Your Electrical Safety Needs

How to Tell if You Have Knob & Tube Wiring in Your Weston Home
Weston has many older homes that still contain original wiring. These signs can help you identify it:
- Porcelain knobs or tubes fastened to beams in the basement or attic
- Cloth-covered or black wiring with frayed or brittle insulation
- Push-button style switches from an earlier era
- Two-prong outlets that do not include a grounding slot
- Homes built before 1950 without a full electrical renovation
You can also send us a picture of what you’re seeing and send it to Castle Electric. Our team can usually identify it right away and let you know whether it is still active.
Is Replacing Knob & Tube Wiring in Weston Worth It?
Many homeowners decide to replace knob and tube wiring in Weston because it solves several concerns at once.
- Modern wiring includes grounding and up-to-date safety protections
- Insurance companies often require removal before issuing or renewing a policy
- You can add insulation safely once the outdated wiring is removed
- Homes with updated wiring tend to perform better during inspections and show better to buyers
- You gain peace of mind knowing your electrical system is no longer running on fragile, aging wiring
After your inspection, we provide clear pricing and explain each part of the work so you know exactly what to expect.
Why Homeowners Call Castle Electric for Knob & Tube Removal
There are two common reasons homeowners reach out to us for knob & tube removal in Weston:
Scenario 1: Home Sale or Insurance Requirement
We frequently get called for things that involve homeowners or buyers navigating insurance requirements or real estate deadlines.
- Home inspectors often uncover old knob and tube wiring, which can slow down the closing process.
- Insurance carriers may decline a renewal or new policy if any active K&T is still in the home.
- Buyers and sellers rely on Castle Electric to replace it quickly, do the work to code, and provide documentation that satisfies insurance companies and inspectors.
If your inspection notes “cloth-wrapped wire,” “old black wiring,” or mentions older push-button switches, those are strong signs the original knob and tube is still present.
Scenario 2: Preparing for Insulation or a Mass Save Visit
If you’re preparing for a Mass Save assessment or an upcoming insulation upgrade, you’ll need proof that no live knob-and-tube wiring is still in use.
Castle Electric takes care of that entire process. We track down every circuit to identify older wiring, update anything that’s still energized, and replace it with safe, code-compliant lines. Once everything is verified and safe, we provide the sign-off your insulation contractor needs so the project can move forward without delays or safety issues.
Mass Save and Electrical Safety
If you’re moving forward with a Mass Save assessment or insulation project, the first step is making sure your home is free of any live knob-and-tube wiring. Mass Save won’t allow new insulation until the electrical system is confirmed safe, and that’s a requirement most homeowners don’t realize until the project is already in motion.
That’s where Castle Electric steps in. We work alongside Mass Save–approved contractors every week to help homeowners clear this requirement quickly and safely:
- Full electrical tracing and confirmation: We follow every accessible circuit to locate any older knob-and-tube wiring and determine whether it’s still energized.
- Safe updates or complete replacement: If we find active sections, we disconnect, replace, or rewire them so everything meets current Massachusetts electrical code.
- Mass Save documentation: Once the wiring is safe, we provide the official clearance your insulation contractor needs before they can move forward.
Addressing old wiring before insulation isn’t just a program requirement; it also prevents overheating risks and protects your home long-term.
