When you replace knob and tube wiring in Charlestown, RI, you’re not just checking a box for your insurance company. You’re eliminating a fire risk that’s been sitting in your walls for decades, waiting for the wrong moment.
Old wiring removal means your electrical system can finally handle what you’re asking it to do. Modern appliances, computers, kitchen equipment—they all need grounded circuits and adequate capacity. Knob and tube can’t deliver that, and pushing it harder doesn’t make it safer.
After the knob and tube upgrade, your home meets current electrical codes. Your insurance stays in place. You can sell without red flags scaring off buyers or tanking your price. And you sleep better knowing the electrical system isn’t a ticking clock.
We work throughout Charlestown, RI, handling old home electrical wiring replacement in properties that have been standing since before modern codes existed. We’re Master Electricians and Electrical Inspector Certified, which means we know what your home inspector is looking for and what your insurance company requires.
Charlestown has plenty of pre-1950s homes, and many still have the original knob and tube wiring tucked behind plaster walls. We’ve seen it all—some of it still functional but outdated, some of it dangerous and deteriorating. Either way, it needs to go.
We don’t treat your project like a quick flip. You get careful work that respects your home’s structure while bringing the electrical system into the present.
First, we walk through your home and assess what’s there. That means checking the attic, basement, and walls to map out where the knob and tube runs. You’ll get a clear picture of what needs replacing and what it’s going to take.
Next comes the removal and installation. We pull out the old wiring and install a new grounded system that meets Rhode Island electrical codes. This usually means running new wire through existing pathways where possible, and opening walls only where necessary. We’re not here to destroy your house—we’re here to rewire it.
Once the new system is in, we test everything, make sure it’s grounded properly, and verify that your electrical panel can handle the load. You get documentation that proves the work was done to code, which is exactly what your insurance company and any future buyer will want to see.
The timeline depends on your home’s size and layout, but most knob and tube wiring removal projects in Charlestown, RI take several days to a couple of weeks. We’ll give you a realistic schedule upfront.

An electrical system upgrade for old homes in Charlestown, RI means more than just new wires. You’re getting a grounded system that protects you from shocks and fires. You’re getting circuits that can handle modern electrical loads without overheating. And you’re getting a setup that meets the National Electrical Code, which is what inspectors and insurance adjusters check against.
Most older Charlestown homes were built with 60-amp service. That was fine when you had a few lights and maybe a radio. Now you’ve got refrigerators, microwaves, computers, HVAC systems, and everything else that demands power. We typically upgrade to at least 100-amp service, sometimes more depending on your home’s needs.
You’ll also get proper grounding in kitchens and bathrooms—the places where water and electricity mix and where the risk is highest. Knob and tube doesn’t have a ground wire, which is why it’s considered unsafe by modern standards.
The work includes a full inspection and documentation. That paperwork matters when you’re dealing with insurance companies or selling your home. It’s proof that a licensed electrician did the job right.
Yes, and it happens more often than you’d think. Most insurance companies in Rhode Island view knob and tube wiring as a high-risk liability. They know it wasn’t designed for modern electrical loads and that the insulation deteriorates over time, increasing fire risk.
Some insurers will give you 30 days after closing to remove it. Others won’t write a new policy at all if they find it during the inspection. And if you’re already covered, don’t assume you’re safe—many companies are now requiring removal as a condition of policy renewal.
Even if your current insurer hasn’t flagged it yet, you’re gambling. If you ever file a claim and they discover knob and tube wiring during the investigation, they can deny coverage or drop you entirely. That’s not a risk worth taking, especially when your home is likely your biggest investment.
Most knob and tube wiring removal projects in Charlestown, RI run between $12,000 and $35,000, depending on your home’s size, layout, and how much wiring needs replacing. Smaller homes with straightforward access tend to fall on the lower end. Larger homes with multiple stories, finished basements, or complex layouts cost more.
The price includes removing the old wiring, installing a new grounded system, upgrading your electrical panel if needed, and bringing everything up to code. It’s not cheap, but it’s also not optional if you want to keep your insurance or sell your home without complications.
Some companies quote by square footage—typically $8 to $17 per square foot. We price each job individually because every home is different. You’ll get a detailed estimate upfront so there are no surprises.
Plan on several days to a couple of weeks for most homes in Charlestown, RI. The timeline depends on your home’s size, how much wiring needs replacing, and how accessible everything is.
A smaller home with an unfinished basement and open attic access moves faster. A larger home with finished spaces, plaster walls, and limited access takes longer because we have to work more carefully to minimize damage.
We’ll give you a realistic timeline before we start. The work does require some disruption—you’ll have electricians in your home, some walls may need to be opened, and power will be off in certain areas while we’re working. But we move efficiently and clean up as we go.
We minimize wall damage wherever possible, but some access points are necessary. The good news is we don’t need to tear apart your entire house to do the job right.
In many Charlestown homes, we can run new wiring through the basement, attic, and existing pathways without major demolition. When we do need to open walls, we’re strategic about it—targeting areas that give us the best access with the least disruption.
After the electrical work is done, you’ll need to patch and repaint those areas. We can coordinate with contractors if you need help with that, but our focus is on getting the electrical system safe and compliant. Most homeowners find the temporary inconvenience is worth it for the peace of mind and the insurance coverage.
Buyers will find it during the home inspection, and it becomes a negotiating point—or a deal-breaker. Many buyers will ask you to remove it before closing, or they’ll demand a price reduction to cover the cost themselves. Some will just walk away, especially if their lender or insurance company won’t approve the purchase with knob and tube present.
Even if you disclose it upfront, you’re limiting your buyer pool to people willing to take on the project. That means longer time on the market and likely a lower sale price. Real estate agents in Charlestown know that knob and tube is a red flag that complicates transactions.
If you’re planning to sell within the next few years, replacing the knob and tube wiring now makes the process smoother. You’ll have documentation proving the electrical system is up to code, which removes a major objection and helps your home show better against comparable properties.
It’s actually dangerous, and that’s why insurance companies care. Knob and tube wiring wasn’t designed for the electrical loads modern homes demand. When you overload it—which happens easily with today’s appliances—the wires heat up. The cloth or rubber insulation that’s been sitting in your walls for 70+ years is often brittle and deteriorating, which increases the risk of arcing and fire.
There’s also no ground wire, which means you don’t have protection against electrical shocks or surges. That’s especially risky in kitchens and bathrooms where water is present. Modern electrical codes require grounding for a reason—it saves lives.
Insurance companies aren’t being difficult just to be difficult. They’re looking at decades of data showing that homes with knob and tube wiring have higher fire risk. Removing it isn’t just about keeping your coverage—it’s about keeping your family safe.
