How Much Do Electrical Upgrades Cost in Naples? | CoHarbor Electric

We get this question in about six different forms a week. Sometimes it’s a homeowner in Naples Reserve who wants an EV charger installed and just wants a ballpark before they commit. Sometimes it’s someone in Barefoot Beach who got quoted for a panel upgrade and has no idea if the number’s fair. Cost is always the first real question, and it should be — nobody wants to schedule an estimate without some sense of what range they’re even in. So here’s the honest rundown, upgrade by upgrade, based on what we actually see across Naples jobs.

Why There’s No Single Number for “Electrical Upgrades”

This is the part that trips people up. “Electrical upgrade” covers a dozen different jobs with wildly different scopes — a GFCI outlet swap and a full panel replacement are both technically “electrical upgrades,” and they’re not in the same conversation price-wise. So instead of one number, here’s what each category actually runs, and what moves the price within each one.

Panel Upgrades

This is usually the biggest-ticket item on the list. In Naples, a panel upgrade typically runs somewhere in the $1,800 to $4,500 range, depending on amperage (100-amp to 200-amp jumps cost more), whether the meter base and service entrance need work alongside the panel, and whether Collier County permitting and inspection reveal anything else that needs addressing while the panel’s open. Older homes near Pelican Bay and Coquina Sands with original 1980s panels tend to land toward the higher end, since there’s usually more supporting work involved — updated grounding, sometimes a full meter can replacement.

Whole-Home Surge Protection

One of the more affordable upgrades on this list, and one we think is underrated given how often Naples gets hit with grid surges after storms. Installed at the panel, whole-home surge protection generally runs a few hundred dollars — a small fraction of what a single surge-damaged AC compressor or refrigerator costs to replace. It’s one of the rare upgrades where the cost-to-protection ratio is genuinely lopsided in the homeowner’s favor.

GFCI and AFCI Circuit Upgrades

Cost here scales almost entirely with how many circuits need protection. A single GFCI outlet replacement in a kitchen or bath is a modest, straightforward job. Bringing an entire older home up to current GFCI and AFCI standards — the kind of work we did recently for a homeowner in Tarpon Cove with a house built in the early 90s — costs more because it touches more circuits, but it’s usually done in a single visit rather than stretching into a multi-day project.

EV Charger Installation

This one depends heavily on distance from the panel to where the charger’s mounted, and whether the panel has room and capacity for the new circuit without a service upgrade. A garage right next to the panel is a straightforward, lower-cost install. A charger on the far side of the house, or a panel that’s already near capacity and needs upsizing first, pushes the number up. We always run the load calculation before quoting this one, because guessing on panel capacity leads to surprises nobody wants mid-job.

Rewiring — Partial or Full

Rewiring is the widest cost range of anything on this list, because “rewiring” can mean replacing a few problem circuits or gutting and rewiring an entire home. A partial rewire — say, addressing one section with aluminum wiring or degraded knob-and-tube remnants in an older Naples Bay or East Naples home — is a fraction of the cost of a full-home rewire, which involves opening walls throughout the house, coordinating with drywall repair, and multiple rounds of Collier County inspection. If you’re facing this decision, get a scope-specific quote rather than relying on a generic “cost per square foot” number — house layout and wall access affect this more than almost any other factor.

Smart Home Electrical Upgrades

Smart panels and app-controlled circuits are a newer category, and pricing varies a lot based on how much of the home you’re converting. A few smart switches is a modest add-on to any other electrical work being done. A full smart panel system that lets you monitor and control circuits remotely — popular with the seasonal homeowners we see around Pine Ridge Road corridor who aren’t in town year-round — is a bigger investment, but one that’s often bundled in with a panel upgrade since the panel’s already being replaced anyway.

What Actually Moves the Number, Across All of These

A few factors show up again and again regardless of which upgrade you’re pricing:

• Access. Attic access, crawlspace access, whether walls need to be opened — all of it affects labor time more than the materials themselves.
• Permitting complexity. Straightforward jobs get straightforward permits. Anything touching the service entrance or adding significant load gets a closer look from Collier County, which can add inspection cycles.
• What we find once we’re in there. This is the honest one. We don’t pad quotes, but we also don’t ignore a corroded connection or an undersized wire we find mid-job just because it wasn’t in the original scope. We’ll always tell you before doing extra work, not after.

The One Thing We’d Tell Every Naples Homeowner Comparing Quotes

A quote that’s dramatically lower than everyone else’s is usually missing something — permit fees, a scope item, or corners that shouldn’t be cut on code-required work like GFCI and AFCI protection. We’d rather walk your home, give you a number based on what’s actually there, and let you compare that against other quotes with full information, than lowball something and revise it upward once the walls are open.

Get an Actual Number for Your Home

Every one of these ranges depends on your specific panel, your home’s age, and what you’re trying to accomplish — a phone estimate only gets you so far. Coharbor Electric is licensed and insured, and we do real site visits before quoting anything, whether you’re in Naples Reserve, Barefoot Beach, Tarpon Cove, or anywhere else across Collier County. Reach out and we’ll walk the property with you and give you a clear, honest number before any work starts.

ally need them, a panel that isn’t maxed out, breakers that don’t trip for no reason. Had a homeowner out in Tanglewood tell us flat out, “I don’t need to control my lights from my phone, I just want to plug in my toaster and my coffee maker at the same time without flipping a breaker.” Fair enough. That’s most people, honestly.

So this one’s for the practical upgrades — the ones that don’t show up in a smart-home ad but make a real difference in how a house actually functions day to day.

Panel Capacity: The Upgrade That Enables Everything Else

Before any other upgrade on this list makes sense, the panel has to be able to support it. A lot of Fort Myers homes — particularly older ones in areas like Villas and Cypress Lake — are still running on 100-amp service that was perfectly fine decades ago and is genuinely tight today. Add a second AC unit, a pool pump, maybe an EV charger down the line, and 100 amps stops having any real margin.

We run a load calculation under NEC Article 220 before recommending anything here — not a guess based on square footage, actual numbers. For most Fort Myers homes today, 200 amps is the standard recommendation, and it’s usually paired with a panel that has more circuit slots too, which solves both the amperage problem and the “there’s no room for another breaker” problem at the same time.

Wiring Updates: Fixing What’s Actually There

If your home was built between roughly 1965 and 1973, there’s a real chance some of the wiring is aluminum rather than copper. It’s not an automatic emergency, but aluminum connections loosen at the terminal in a way copper doesn’t, and that’s where heat builds over time. We check for this specifically in homes from that era — we’ve found it more than once in older sections of Six Mile Cypress and Olga.

For homes where the wiring’s fundamentally sound but a few circuits are undersized or overloaded — say, a kitchen running on the same circuit as half the rest of the house — targeted rewiring of just those circuits is often enough. You don’t always need a full rewire to fix a real problem. Sometimes it’s a handful of circuits that need updating, not the whole house.

Outlet Upgrades: More Than Just Adding More of Them

Older Fort Myers homes frequently have too few outlets for how people actually live now — everyone’s got more devices than the house was built to accommodate. But adding outlets is only half of it. Under NEC Article 210, kitchens, bathrooms, garages, and outdoor spaces need GFCI protection, and a lot of homes still have standard outlets in those locations, sometimes with a three-prong plug swapped in over an ungrounded two-prong circuit — which looks fixed but isn’t actually grounded.

AFCI protection is worth mentioning too. It’s increasingly required on circuits serving bedrooms and living spaces, and it protects against a different kind of hazard than GFCI does — arc faults, which GFCI protection doesn’t catch. If you’re updating outlets anyway, this is the moment to bring those circuits up to current code rather than just adding more of the same.

Whole-Home Surge Protection

Florida’s storm season means power surges are a regular occurrence here, not a rare event — lightning strikes near the grid, FPL switching operations during outages, the electrical equivalent of a jolt every time the power blinks. A whole-home surge protector installed at the panel catches these before they reach anything plugged into your walls, which matters a lot more than the point-of-use surge strips most people rely on for a TV or computer. Those strips protect one device. A panel-level surge protector protects everything at once.

GFCI and AFCI Breaker Replacements Without a Full Remodel

You don’t need to be mid-renovation to update your protection. If your panel’s original and never had GFCI or AFCI breakers added, we can often swap individual breakers to add that protection without opening walls or doing any invasive work. It’s one of the more cost-effective safety upgrades available, and it’s a good candidate for homeowners who want meaningful improvement without a big project.

Common Mistakes We See With These Upgrades

Adding outlets without checking the circuit they’re on. More outlets on an already-loaded circuit just means more things competing for the same limited capacity.

Assuming three-prong outlets mean the circuit is grounded. It’s an easy assumption, and it’s wrong more often than people expect in older homes.

Skipping the load calculation before adding load. Whether it’s more outlets, an appliance upgrade, or anything else pulling more power, guessing at capacity instead of calculating it is how panels get pushed past what they can handle.

Treating surge protection as optional. In a region that sees the storm activity Fort Myers does, panel-level surge protection is one of the more overlooked upgrades — and one of the more affordable ones relative to what it protects against.
