Your insurance company stops threatening to drop you. That’s usually the first thing homeowners notice after old wiring removal in Cranston, RI.
Most carriers won’t insure homes with knob and tube wiring, and the ones that do charge 50-100% more. You’re paying extra every month for a system that can’t handle your coffee maker and laptop running at the same time.
After an electrical system upgrade for old homes in Cranston, you get grounded outlets that actually protect your electronics. You can run your air conditioner without worrying about overloaded circuits. Your home inspector stops flagging your electrical panel as a liability. And if you’re selling, buyers can actually get financing without the bank balking at outdated wiring.
The upgrade also means your home meets current electrical code. That matters when you want to renovate your kitchen or finish your basement. Without it, you’re stuck.
We’ve spent over 30 years working on Rhode Island homes, including plenty of the historic properties in Edgewood, Oaklawn, and Garden City where knob and tube wiring is still common. We’re licensed Master Electricians who know how to rewire old homes without tearing apart your plaster walls more than necessary.
We’ve seen what happens when homeowners ignore old wiring. We’ve also seen the relief when insurance companies send approval letters after an upgrade. Cranston has thousands of homes built between 1880 and 1950, and a lot of them still have the original electrical system that wasn’t designed for anything beyond a few light bulbs.
We handle the permits, the inspections, and the actual work. You get a system that’s safe, grounded, and built to last.
We start with an assessment of your current system. That means checking your attic, basement, and walls to see where the old wiring runs and what condition it’s in. We’ll tell you exactly what needs to be replaced and why.
Next, we map out the new wiring plan. We run modern, grounded cables through your walls using access points that minimize damage. In most Cranston homes, we can fish wires through existing spaces without ripping out entire walls. Where we do need to open walls, we keep it surgical.
We install a new electrical panel that can handle modern loads. We add grounded outlets throughout your home. We make sure every circuit is properly protected. Then we handle the inspection with the city so everything’s documented and code-compliant.
The whole process typically takes a few days to a week, depending on your home’s size. You’ll have power during most of the work. When we’re done, you’ll have an electrical system that works the way it should.

A knob and tube upgrade in Cranston, RI means removing all the old ungrounded wiring and replacing it with modern electrical cables. You get a new breaker panel with proper circuit protection. Every outlet gets upgraded to grounded three-prong receptacles. We add dedicated circuits for high-demand appliances like your refrigerator, microwave, and HVAC system.
We also handle all the permitting and inspection requirements with the City of Cranston. That documentation matters when you’re dealing with insurance companies or selling your home. You’ll get proof that a licensed electrician did the work correctly.
Most Cranston homes need between 100 and 200 amps of service. We’ll size your new panel based on your actual usage and future needs. If you’re planning to add central air or finish your basement later, we account for that now so you’re not undersized from day one.
The work includes testing every circuit, labeling your panel clearly, and making sure your system is safe for the next several decades. This isn’t a patch job. It’s a complete old wiring removal that brings your home up to current standards.
Most Cranston homeowners pay between $12,000 and $25,000 for complete knob and tube wiring removal, depending on the size of their home and how accessible the wiring is. A 1,500 square foot home typically runs $15,000 to $20,000. Larger homes or properties with limited attic and basement access cost more because the work takes longer.
The price includes removing all the old wiring, installing a new electrical panel, running modern grounded cables, upgrading all outlets and switches, and handling permits and inspections. If your home has plaster walls or needs significant wall repairs afterward, that adds to the cost.
Some electricians charge by the square foot, usually $10-20 per square foot. We price based on the actual scope of work after we assess your home. That way you know exactly what you’re paying for and why.
Yes, many insurance companies in Rhode Island will either refuse to insure your home or charge significantly higher premiums if they discover knob and tube wiring. Some won’t renew your policy once they find out. Others will give you 30-60 days to replace it or they’ll cancel your coverage.
The companies that do insure homes with old wiring typically charge 50-100% more because the fire risk is real. Knob and tube wiring wasn’t designed for modern electrical loads, and the insulation around the wires deteriorates over time. That creates hot spots that can ignite surrounding materials.
If you’re buying a home in Cranston with knob and tube wiring, your lender might require you to replace it before closing. Even if they don’t, your insurance options will be limited and expensive. Getting the wiring upgraded before you have an insurance issue is a lot less stressful than scrambling to find coverage after a cancellation notice.
You can do a partial replacement, but it won’t solve your insurance problem and it creates other issues. Insurance companies want all the knob and tube wiring gone, not just some of it. They’re not going to give you credit for replacing half your electrical system.
Mixing old and new wiring also makes troubleshooting problems harder down the road. If something goes wrong, the next electrician has to figure out which circuits are updated and which aren’t. That wastes time and costs you money.
The bigger issue is that partial replacements don’t give you the capacity you need. If you’re only upgrading the circuits in your kitchen but leaving the old wiring everywhere else, you still can’t run modern appliances throughout your home without overloading something. A complete electrical system upgrade for old homes in Cranston, RI gives you a clean slate and eliminates all the fire hazards at once.
Most knob and tube wiring removal projects in Cranston take between three days and two weeks, depending on your home’s size and complexity. A typical 1,500 square foot home usually takes about a week. Larger homes or properties with difficult access take longer.
The timeline depends on how easy it is to run new wiring through your walls. Homes with accessible attics and basements go faster because we can fish wires without opening many walls. Homes with finished attics, no basement, or plaster walls take more time because access is limited.
You’ll have power during most of the work. We typically shut off electricity for short periods while we’re connecting circuits or installing the new panel. We schedule those outages so they’re minimally disruptive. The city inspection happens at the end, and that usually adds a day or two to the timeline depending on their schedule.
We open walls only where necessary, and we keep it minimal. In most Cranston homes, we can fish new wiring through existing spaces like attics, basements, and wall cavities without major demolition. We use access points at outlets, switches, and light fixtures to run cables vertically and horizontally.
Some wall opening is usually unavoidable, especially where we need to install new outlet boxes or run wires across framing members. We cut small access holes, do the work, and patch them afterward. If you have plaster walls, we’re careful because plaster is more fragile than drywall.
The extent of wall work depends on your home’s layout. A home with an unfinished basement and open attic requires very little wall opening. A home with a finished basement, no attic access, and multiple stories requires more. We’ll walk through your home during the estimate and show you exactly where we’ll need access and why.
Hire a licensed Master Electrician who’s done this work before, not a handyman or unlicensed contractor. Knob and tube wiring removal requires pulling permits and passing inspections with the City of Cranston. If the work isn’t done by a licensed electrician, it won’t pass inspection and your insurance company won’t accept it.
Ask how many old home rewiring projects they’ve completed. Electricians who mostly do new construction don’t always know how to work around plaster walls, limited access, and the quirks of historic homes. You want someone who’s rewired homes in Edgewood, Oaklawn, and other older Cranston neighborhoods where this wiring is common.
Get a detailed written estimate that breaks down the scope of work, not just a price per square foot. You should know what’s included—new panel, number of circuits, outlet upgrades, permit fees, inspection costs. And make sure they’re insured. If something goes wrong during the work, you need to know their insurance will cover it.
