Your insurance company stops threatening to drop you. Most carriers in Rhode Island won’t insure homes with active knob and tube wiring, and the ones that do charge significantly more. Once you replace knob and tube wiring in North Smithfield, that problem disappears.
You can actually use your outlets without worrying. Knob and tube systems weren’t designed for modern electrical loads. Your kitchen appliances, home office equipment, and HVAC systems all demand more power than these old circuits can safely handle. After an electrical system upgrade for old homes, you get grounded outlets, adequate capacity, and the ability to plug in what you need without overloading anything.
Your home becomes easier to sell when the time comes. Buyers in North Smithfield know what knob and tube wiring means—inspection red flags, insurance headaches, and safety concerns. Remove it now, and you eliminate a major obstacle that kills deals or drives down offers. You’re not just fixing a problem. You’re protecting what’s likely your largest investment.
We’ve spent over 30 years handling electrical work across Rhode Island, including plenty of old home electrical wiring replacement in North Smithfield. We’re not new to this. We’ve seen every variation of knob and tube wiring—some still functional but outdated, others actively dangerous.
North Smithfield has its share of older homes, especially those built before 1950. Many of these properties still have original wiring tucked behind plaster walls and running through unfinished attics. We know how to work in these spaces without tearing your house apart. Our electricians are licensed, insured, and familiar with Rhode Island electrical codes and local inspection requirements.
You’re hiring people who show up on time, do the work right, and don’t leave a mess. We handle the permits, coordinate inspections, and make sure everything passes the first time.
First, we come out to look at your electrical system. We need to see what you’re working with—how much knob and tube wiring is still active, where it’s located, and what your current electrical panel can handle. This isn’t a sales pitch. It’s an assessment so we can give you an accurate estimate and timeline.
Next, we map out the rewiring plan. Some homes need a full rewire. Others only have knob and tube in certain areas, like the second floor or attic circuits. We identify which circuits need replacement, where we’ll run new wiring, and how we’ll minimize damage to your walls and ceilings. Most jobs in North Smithfield take one to two weeks, depending on the size of your home and how much wiring needs replacement.
Then we do the work. We pull permits, install new wiring with proper grounding, upgrade your electrical panel if needed, and replace old outlets and switches. Once everything’s in, we schedule the inspection with the local authority. After it passes, we provide you with documentation for your insurance company. That’s it—you’re done, and your home is safe.

You get new wiring throughout the affected areas of your home. We install modern Romex cable with ground wires, which is what current electrical codes require. This means your outlets, switches, and fixtures all get proper grounding—something knob and tube systems don’t have.
Your electrical panel usually needs an upgrade too. Most older homes in North Smithfield have 60- or 100-amp panels, which aren’t enough for today’s electrical demands. We typically install a 200-amp panel to handle everything from your HVAC system to your kitchen appliances without tripping breakers. You also get new circuit breakers that actually protect your home instead of old fuses that people sometimes bypass with pennies or overfused replacements.
We replace outdated outlets and switches with grounded versions. Bathrooms and kitchens get GFCI outlets for shock protection. We add circuits where you need them so you’re not running extension cords or overloading existing outlets. Everything gets tested, inspected, and documented. You receive copies of all permits and inspection reports, which you’ll need for your insurance company and future home sales.
Most full rewiring jobs in North Smithfield run between $12,000 and $35,000, depending on your home’s size and how much wiring needs replacement. The cost breaks down to roughly $8 to $17 per square foot. A 1,500-square-foot home typically costs $12,000 to $25,000. Larger homes or those with difficult access can push toward the higher end.
Partial rewiring costs less if only certain areas still have knob and tube wiring. Some homes only need the second floor or attic circuits replaced, which might run $5,000 to $12,000. The price depends on how many circuits we’re replacing and whether your electrical panel needs upgrading.
Panel upgrades add to the total cost but are usually necessary. Going from a 60-amp or 100-amp panel to a 200-amp service costs $2,000 to $4,000 on its own. Most insurance companies and electrical codes require adequate panel capacity when you’re doing major rewiring work. We give you an exact quote after we assess your home—no surprises, no upselling.
Yes, most insurance companies in Rhode Island either refuse to insure homes with active knob and tube wiring or give you 30 to 60 days to remove it. Some carriers will insure you but charge significantly higher premiums—sometimes 20% to 40% more than standard rates. Others won’t cover fire damage related to electrical issues if they know the wiring is old.
The problem is that knob and tube wiring is a documented fire hazard. The insulation around the wires degrades over time, and the system has no grounding. When insulation gets added to attics—which many North Smithfield homeowners have done for energy efficiency—it traps heat around the wiring and increases fire risk. Insurance companies know this, which is why they’re strict about it.
If you’re buying a home and the inspection reveals knob and tube wiring, your lender might require removal before closing. If you already own the home and your carrier discovers it during a routine inspection or claim, expect a letter demanding removal or face cancellation. Don’t ignore it. The deadline is real, and finding coverage elsewhere with active knob and tube wiring is nearly impossible.
Most complete rewiring jobs in North Smithfield take one to two weeks. The timeline depends on your home’s size, how much wiring needs replacement, and how accessible everything is. A smaller home with open attic and basement access goes faster. A larger home with finished ceilings and limited access takes longer.
We’re working in your home during this time, but you don’t have to move out. We shut off power to specific circuits while we work on them, so you’ll have some inconvenience—maybe no power in the bedrooms one day, then the kitchen the next. We coordinate with you to minimize disruption and usually keep at least some power available throughout the house.
After the wiring is in, we schedule the inspection with the local building department. Rhode Island inspections usually happen within a few days of our request. Once it passes, you’re done. We clean up, provide all documentation, and you can send proof of the upgrade to your insurance company. The whole process from start to finish—including permits and inspections—typically wraps up in two to three weeks.
We minimize wall and ceiling damage, but some is usually unavoidable. The good news is that most knob and tube wiring runs through attics, basements, and crawl spaces where we have open access. We fish new wiring through these areas and down to outlets and switches without opening walls.
When we do need to open walls, we’re strategic about it. We might cut small access holes near outlets or along baseboards rather than tearing out entire sections. In some cases, we run wiring through closets or other less visible areas to avoid damage in main living spaces. Older North Smithfield homes with plaster walls require more care than drywall, but we’ve done plenty of both.
You’ll need to patch and paint afterward, or hire someone to do it. We’re electricians, not drywall contractors, so we don’t include finishing work in our estimates. Most homeowners hire a handyman or painter to patch the holes we make, which usually costs a few hundred to a thousand dollars depending on how much patching is needed. It’s an extra expense, but it’s still worth it to get rid of unsafe wiring and restore your insurance coverage.
You’re gambling with your insurance coverage and your home’s safety. If your insurance company knows about the wiring and you don’t remove it, they’ll cancel your policy. If they don’t know about it and you file a claim related to electrical issues, they could deny the claim and potentially cancel you for non-disclosure. Either way, you’re unprotected.
The fire risk is real. Knob and tube wiring causes nearly half of all electrical fires in older homes, according to national fire safety data. The insulation deteriorates, the system has no grounding, and it wasn’t designed for modern electrical loads. Every time you plug in a space heater, run your microwave, or charge multiple devices, you’re stressing a system that’s 70 to 100 years old.
Your home’s value takes a hit too. When you eventually sell, buyers will either walk away or demand a significant price reduction to cover the cost of rewiring. Some won’t even make an offer because they can’t get insurance or financing. You’re better off handling it now rather than letting it become someone else’s problem—or worse, your problem during an emergency.
Yes, electrical rewiring requires a permit in North Smithfield, and the work must be inspected by the local building department. This isn’t optional. Rhode Island electrical code requires permits for any major electrical work, and replacing knob and tube wiring definitely qualifies. We pull the permits as part of our service, so you don’t have to deal with the paperwork.
The permit process protects you. It ensures the work meets current electrical codes and gets inspected by someone independent who verifies everything is safe. Your insurance company will want proof that the work was done correctly, and the inspection report provides that documentation. Without it, they might not accept that the wiring was actually replaced.
Some homeowners ask about doing the work without a permit to save money. Don’t. If you ever sell your home, unpermitted electrical work becomes a disclosure issue and a deal-killer. If something goes wrong and your insurance company finds out the work wasn’t permitted, they can deny your claim. The permit costs a few hundred dollars and takes a few days to process—it’s not worth skipping.
