Your insurance company stops flagging your policy. You can finally add insulation through Mass Save without creating fire hazards. Your home qualifies for financing if you decide to sell or refinance.
Modern appliances work the way they’re supposed to because your electrical system has proper grounding. You’re not guessing whether plugging something in is safe. You have documentation that proves your electrical system meets current Massachusetts code.
If you’re planning solar panels, a heat pump, or an EV charger, your home is ready. You’re not blocked from energy efficiency upgrades because your wiring can’t handle insulation. The electrical system in your Swansea home works for how you actually live today, not how people lived in 1920.
We work throughout Swansea and Bristol County on homes built before modern electrical standards existed. We’ve seen what happens when insurance companies require inspections, when Mass Save flags old wiring during energy audits, and when homeowners realize their electrical system is blocking necessary upgrades.
Swansea has a significant number of homes built before 1940, and many still have original knob and tube wiring. We understand the layout of these older homes, how the wiring was originally installed, and what it takes to replace it without tearing apart walls unnecessarily.
You get licensed electricians who provide the documentation your insurance company or lender needs. We’re not trying to upsell you on things you don’t need—we’re focused on getting your electrical system updated so you can move forward with whatever project brought you here in the first place.
We start with an inspection of your existing electrical system to map out where knob and tube wiring runs through your Swansea home. You’ll know exactly what needs to be replaced, what can stay, and what the project involves before any work starts.
The removal process involves running new wiring that meets current code, installing proper grounding, and connecting everything to your electrical panel. We work to minimize wall damage—sometimes we can fish wiring through existing spaces, other times we need strategic access points that we repair after.
Your old knob and tube wiring gets completely removed, not just disconnected. You’re left with a modern electrical system that handles today’s power demands. We provide written documentation that confirms the work meets Massachusetts electrical code and satisfies insurance requirements.
The timeline depends on your home’s size and how much wiring needs replacement, but most Swansea homes take several days to a week. You’ll have power throughout the process—we’re not leaving you in the dark while we work.

You get a complete assessment of your current electrical system before we start. We identify all knob and tube wiring locations, check your electrical panel capacity, and determine if upgrades are needed to support modern electrical loads.
The replacement includes new wiring with proper grounding throughout affected areas of your Swansea home. Your electrical panel gets updated if it can’t handle current safety standards or power requirements. All work meets the 2020 National Electrical Code that Massachusetts follows.
We coordinate with your insulation contractor if you’re doing this for a Mass Save project. Many Swansea homeowners are replacing knob and tube wiring specifically to qualify for Mass Save’s 0% interest loans and insulation rebates—we make sure the electrical work doesn’t hold up your energy efficiency upgrades.
You receive documentation that proves the old wiring is gone and your system is code-compliant. This matters for insurance coverage, home sales, refinancing, and any future work that requires electrical permits. With 21.3% of Swansea homes built before 1940, having this documentation separates your property from others still carrying outdated electrical systems.
Many insurance companies in Massachusetts either deny coverage outright for homes with knob and tube wiring or require a licensed electrician to inspect and certify it’s safe. Some will cover it temporarily but require removal within a specific timeframe, often 30-60 days.
If you’re trying to get new coverage or switch providers, knob and tube wiring often blocks the application. Insurance companies view it as a fire risk, especially when insulation is present or when the wiring is over 80-100 years old and the insulation around the wires has deteriorated.
Even if your current insurer hasn’t flagged it yet, that changes when you file a claim or try to update your policy. Getting ahead of it means you’re not scrambling to find an electrician when you’re up against an insurance deadline. The documentation we provide after a knob and tube upgrade in Swansea satisfies most insurance requirements and removes that barrier to coverage.
No, you can’t safely bury knob and tube wiring in insulation. The system was designed to dissipate heat in open air—when you surround it with insulation, it overheats and becomes a fire hazard.
This is why Mass Save requires a knob and tube inspection before approving insulation projects. If they find active knob and tube wiring in areas where you want to add insulation, the project stops until you replace the old wiring. You’re stuck between wanting better energy efficiency and having an electrical system that won’t allow it.
Many Swansea homeowners don’t realize their home has knob and tube wiring until they try to insulate through Mass Save. At that point, you need to decide whether to replace the wiring and move forward with insulation, or skip the energy efficiency upgrades. Mass Save offers 0% interest loans up to $25,000 specifically for electrical upgrades that enable insulation work, which makes the knob and tube removal more affordable than paying out of pocket.
Cost depends on how much wiring needs replacement, whether your electrical panel needs upgrading, and how accessible the wiring is in your home. A single room might run a few thousand dollars, while a whole-house replacement in a larger Swansea home could be $8,000-$15,000 or more.
The size and layout of older homes in Swansea varies significantly—a small Cape is different from a larger Colonial. Homes with finished basements or multiple stories take longer because there’s more area to cover and access can be more complicated.
Mass Save’s 0% interest loans cover knob and tube removal when it’s blocking insulation work, which spreads the cost over time without interest charges. Income-qualified homeowners can access up to $100,000 in financing. Even without Mass Save, the investment pays back through insurance approval, increased home value, and the ability to complete other upgrades your home needs. You’re not just paying to remove old wiring—you’re removing obstacles to insulation, refinancing, and selling your home when the time comes.
Most residential projects in Swansea take anywhere from three days to two weeks depending on the scope. A partial replacement in a few rooms goes faster than a whole-house rewire. Homes with easier attic and basement access move quicker than homes where we need to open walls.
You’ll have power during the work—we’re not shutting down your entire electrical system for days. We work in sections, replacing wiring and keeping your home functional. Some disruption is unavoidable, but we’re not leaving you without electricity or tearing apart your house unnecessarily.
The timeline also depends on whether your electrical panel needs upgrading. If your current panel can’t support the new wiring or doesn’t meet code, that adds time to the project. We’ll know this during the initial inspection so you’re not surprised halfway through. Most Swansea homeowners are more concerned about getting it done right than getting it done fast—this isn’t work you want to rush or cut corners on.
It depends on what you’re trying to accomplish. If you’re doing this for insurance approval, most companies want all active knob and tube wiring removed or certified safe by a licensed electrician. If you’re doing it for Mass Save insulation, you only need to replace wiring in areas where insulation will be added.
Some homeowners replace wiring in stages—starting with the areas causing immediate problems and handling the rest later. That works if your insurance company allows it and you’re not planning to sell soon. But if you’re already opening walls and bringing in an electrician, completing the whole job at once is usually more cost-effective than doing it in pieces.
Leaving some knob and tube wiring in place means you’ll still have limitations. You can’t fully insulate, you’re still dealing with an outdated system in parts of your home, and you’ll eventually need to address it anyway. Most Swansea homeowners who start with a partial replacement end up wishing they’d done the whole house when they had the chance. The disruption happens once, the financing is available now, and you’re done dealing with it.
You’ll keep running into the same obstacles. Insurance companies will continue flagging it or denying coverage. You can’t add insulation without creating fire hazards. Selling your home becomes harder because buyers’ lenders often won’t finance properties with knob and tube wiring, or buyers walk away entirely when the inspection reveals it.
You’re also stuck with an electrical system that wasn’t designed for modern power loads. Knob and tube wiring has no grounding, which means you can’t safely use three-prong appliances the way they’re intended. You’re limited in what electrical upgrades you can make—forget about adding solar panels, a heat pump, or an EV charger.
The wiring itself continues aging. The rubber insulation around the wires deteriorates over time, increasing fire risk. If something goes wrong and you have an electrical fire, insurance claims can be denied or complicated if they determine the old wiring contributed to the problem. You’re not saving money by avoiding the upgrade—you’re just delaying an inevitable expense while accepting more risk and fewer options for your Swansea home.
