Your insurance company stops threatening to drop your coverage. Your home’s electrical system can finally handle modern appliances without tripping breakers or creating fire risks. And most importantly, your walls stay intact.
If you own an older home in Woonsocket, you’ve probably heard the horror stories. Most electricians tell you they’ll need to cut into your walls, tear out sections of plaster, and leave you with a repair bill that rivals the electrical work itself. That’s not how we work.
We insert a specialized camera through your existing outlets to locate and remove knob and tube wiring from inside your walls. No demolition. No plaster dust covering your furniture. No trying to match 80-year-old horsehair plaster that’s impossible to replicate.
You get code-compliant wiring that satisfies your insurance company and keeps your family safe. Your home keeps its original character. And you avoid the mess and expense that comes with traditional rewiring methods.
Lightning Electric has spent over 30 years working on older homes across Rhode Island. We’re licensed Master Electricians who understand what you’re dealing with when you own a historic property in Woonsocket.
Nearly half the homes in Woonsocket were built before 1940. That means horsehair plaster walls, uneven studs, and electrical systems that were designed when families owned maybe three light bulbs and a radio. We’ve seen it all.
We’re not the cheapest option, and we won’t pretend to be. But we’re the only electrician in the area using this camera system. Everyone else will tell you they need to cut into your walls. We don’t. That difference matters when you’re trying to preserve original plaster that can’t be matched or replaced.
We start by inserting our specialized camera system through your existing electrical outlets. This lets us see inside your walls without opening them up. We can locate every section of knob and tube wiring, identify any problems like mouse damage or deteriorated insulation, and find covered junction boxes or open joints that need attention.
Once we’ve mapped everything out, we remove the old wiring and install new, grounded electrical lines. The camera guides us through the process so we know exactly where we’re working. In most cases, we don’t touch your walls at all. If we do need to make any access points, they’re minimal—small notches at most, not the gaping holes you’d see with traditional methods.
When we’re done, you get a Certificate of Insurance showing that licensed Master Electricians completed the work and it passed inspection. That’s what your insurance company needs to restore your coverage. Most of our clients see their policies reinstated within days, and some even see their premiums drop.
The whole process typically takes a few days depending on your home’s size. You can stay in your home while we work. And when we leave, your walls look the same as when we arrived—just with safer, modern wiring behind them.

Woonsocket has one of the oldest housing stocks in Rhode Island. About 41.7% of homes here were built before the 1940s, back when knob and tube wiring was standard. These homes have character and history, but they also have electrical systems that weren’t designed for how we live today.
Your insurance company knows this. That’s why most carriers in Rhode Island either refuse to cover homes with active knob and tube wiring or give you 30 days to remove it. If they find it during an inspection and you haven’t upgraded, they’ll cancel your policy. Then you’re stuck paying triple rates for high-risk coverage—if you can find it at all.
The traditional solution involves cutting open your walls, which creates a nightmare if you have horsehair plaster. That material is nearly impossible to match. The texture is different. The composition is different. Even experienced plasterers struggle to make repairs blend in. You end up with visible patches that stand out forever.
Our camera-based approach solves this problem. We preserve your original plaster completely. Your home keeps its historic authenticity. And you get the modern electrical capacity you need for computers, kitchen appliances, and all the electronics that are part of daily life now.
This isn’t just about meeting code requirements. It’s about protecting your investment in a historic property while making it safe and functional for your family.
Yes. Most insurance companies in Rhode Island either won’t cover homes with knob and tube wiring or require you to remove it within 30 days of discovering it. They see it as a fire liability, and they’re not wrong—the wiring lacks grounding, the insulation deteriorates over time, and it wasn’t designed to handle modern electrical loads.
Once you complete the removal and we provide your Certificate of Insurance showing the work was done by licensed electricians and passed inspection, your coverage typically gets reinstated within days. Some homeowners even see their premiums drop because the fire risk is gone.
The documentation matters. Insurance companies want proof that a Master Electrician did the work properly and that it meets current electrical codes. We provide everything you need to satisfy those requirements.
Every other electrician in the area will tell you they need to cut into your walls to remove knob and tube wiring. That’s the traditional method—open up sections of wall, pull out the old wiring, snake in new lines, then patch and repair the damage. It works, but it’s messy, expensive, and destructive.
Our camera system changes that completely. We insert a specialized camera through your existing outlets to see inside your walls. This lets us locate all the old wiring, identify any problems, and map out the best route for new lines—all without opening your walls.
The camera shows us exactly what we’re dealing with. We can spot mouse damage, deteriorated insulation, covered junction boxes, and any other issues that need attention. Then we remove the old wiring and install new lines with minimal to no wall damage. In most cases, we don’t touch your walls at all. If we do need any access points, they’re small notches at most—nothing like the holes you’d see with traditional methods.
This approach is especially valuable for historic homes with horsehair plaster, which is nearly impossible to match if you damage it. We preserve your original walls completely.
Complete home rewiring in Rhode Island typically ranges from $12,000 to $36,000, depending on your home’s size and complexity. That breaks down to roughly $10-$20 per square foot. Your actual cost depends on how much wiring needs replacement, how accessible it is, and what your home’s layout looks like.
We’re not the cheapest option. Our camera system and specialized approach cost more than traditional methods. But you’re not paying for drywall repair, plaster matching, repainting, or dealing with the mess that comes with cutting open walls. You’re also not living in a construction zone for weeks while repairs get completed.
Most homeowners find that our approach actually saves money when you factor in the avoided repair costs. And the value of preserving your original plaster—especially horsehair plaster that can’t be replicated—is hard to put a price on if you care about maintaining your home’s historic character.
We can give you an accurate quote after inspecting your home and understanding what you’re working with.
Knob and tube wiring was the standard electrical system installed in homes from about 1880 through the 1940s. It uses ceramic knobs to hold wires in place and ceramic tubes to protect wires where they pass through framing. The system worked fine for its time, when homes had minimal electrical needs.
The problems come from age and modern usage. The wiring lacks a ground wire, which means your electronics aren’t protected from power surges and there’s higher risk of electrical shock. The insulation deteriorates over time, especially if it’s been disturbed by renovations or damaged by rodents. And the system simply can’t handle the electrical load of modern appliances, computers, televisions, and all the other devices we use daily.
Insurance companies see knob and tube wiring as a fire hazard. Many carriers refuse to insure homes that have it. The ones that do often charge significantly higher premiums or require removal within a specific timeframe.
Beyond the insurance issues, knob and tube wiring limits what you can do with your home. You can’t safely add insulation in walls or attics where the wiring runs because it needs air circulation to dissipate heat. You can’t upgrade to modern electrical panels. And you’re constantly at risk of overloading circuits that were designed for a fraction of today’s power demands.
Technically, knob and tube wiring that’s in good condition and hasn’t been modified isn’t illegal. But “still working” doesn’t mean it’s safe or adequate for how you’re using electricity today. And your insurance company almost certainly won’t let you keep it.
Most carriers in Rhode Island either refuse to write policies for homes with knob and tube wiring or give you 30 days to remove it after they discover it. If you try to hide it and they find it later during a claim, they can deny coverage entirely. That puts your entire investment at risk.
Even if you could keep your insurance, the wiring itself creates real hazards. It lacks grounding, which increases shock risk and leaves your electronics vulnerable. The insulation deteriorates over time. And the system can’t safely handle modern electrical loads, which creates fire risk every time you plug in multiple appliances.
There’s also the resale issue. Many buyers won’t touch a home with knob and tube wiring, and the ones who will expect a significant price reduction to cover removal costs. You’re better off addressing it now on your terms rather than being forced to deal with it during a sale or after your insurance company issues an ultimatum.
Most knob and tube wiring removal projects take anywhere from a few days to a week, depending on your home’s size and how much wiring needs replacement. The timeline also depends on whether we’re rewiring your entire home or just specific sections.
You can absolutely stay in your home during the work. We’re not tearing into walls or creating the kind of mess that forces you to move out. Our camera system keeps the disruption minimal. We’ll need to turn off power to specific circuits while we work on them, but we coordinate that with you so you’re never without electricity for extended periods.
The actual process is straightforward. We inspect your home first to map out all the knob and tube wiring using our camera system. Then we remove the old wiring and install new, grounded lines. Once everything is installed, we have the work inspected to ensure it meets code. Then we provide you with documentation showing the work was completed by licensed Master Electricians and passed inspection.
That documentation is what your insurance company needs to restore your coverage. Most homeowners see their policies reinstated within days of completion. The whole process is designed to be as smooth and non-disruptive as possible while giving you the safer, modern electrical system your home needs.
