Case Study: 1965 Naples Home Staged Upgrade

We got a call last spring from a homeowner in Naples — small brick house off Airport-Pulling, built in 1965. Mark was his name. Nice guy, retired teacher. He said the lights flickered every time the dryer ran and one outlet in the living room felt warm. He didn’t want a total remodel, just wanted things safe.

We’ve seen this story a hundred times around here. Old Florida homes built tough, but with wiring that’s way behind the times. Back then, 100 amps was plenty. These days, between air conditioners, pool pumps, and all the electronics, it barely keeps up.

So we told Mark, “Let’s go slow and smart. We’ll handle this in stages — make it safe now, plan for upgrades later.”

That’s how the staged upgrade idea came together.

Step 1: Checking Things Out

We always start by opening up the panel. Sure enough, his was an old fuse-style box, original to the home. A few breakers were double-tapped — two wires under one lug — and we spotted a couple of aluminum splices mixed with copper. Not the worst we’ve seen, but definitely not safe.

Inside, the outlets were two-prong, no grounding. The kitchen had one circuit running half the appliances. No wonder the lights dimmed every time he made toast.

We told him the truth: “You don’t need to rip every wire out, but this panel’s gotta go, and we’ve gotta clean up these connections before something overheats.”

He nodded. “As long as I can keep my walls intact, do what you have to do.”

Step 2: New Service Panel

We pulled out the old 100-amp box and swapped it for a 200-amp Square D QO panel — nice and solid, with room to grow.

Every wire got cleaned, retorqued, and labeled. The aluminum-to-copper joints? We used proper connectors, not the twist-and-tape nonsense we sometimes find.

Naples humidity eats metal alive, so we sealed the service entry and used corrosion-resistant lugs. The whole thing took a day. When we powered it back up, the lights stayed steady — no more flicker when the dryer kicked on. Mark smiled. “Didn’t think I’d ever see that day.”

If you want to see how a similar service change-out played out in Fort Myers, this 200A panel upgrade shows how added capacity set that home up for future projects and backup power.

Step 3: Tackling the Aluminum Wiring

The wiring itself was still the original aluminum, and surprisingly, not in terrible shape. Some oxidation, sure, but no burn marks or cracks. We gave Mark two options:

• Full rewire — tear into the walls and start fresh with copper.

• Pigtailing — connect short copper leads to each aluminum wire using approved AlumiConn connectors.

He chose pigtailing. Smart move for his budget, and totally safe if done right.

We hit every outlet, switch, and light fixture in the house. Cleaned the wires, added antioxidant compound, and installed the connectors. Took our time. You can’t rush aluminum work — it’s all about clean, tight contact.

By the end of day three, every circuit was pigtailed and grounded.

Step 4: Grounding & Surge Protection

Back in the ‘60s, they didn’t bother grounding half these homes. Mark’s wasn’t grounded at all. We drove in two copper rods outside and bonded them to the new panel. That brought the whole house up to modern code.

While we were at it, we added a whole-home surge protector. Naples gets hammered with summer lightning. We’ve seen one strike a neighbor’s palm tree and take out three TVs across the street.

It’s one of those things you don’t think about until you lose a $4,000 refrigerator board. Not on our watch.

Step 5: The Kitchen and Lighting

Once the wiring and panel were safe, we tackled comfort.

The kitchen had one sad fluorescent light in the middle of the ceiling. We pulled it out and installed four LED recessed lights and under-cabinet strips on a dimmer. The whole room felt brand new — and cooler, too. Those old fixtures gave off more heat than light.

We also added a second circuit in the kitchen so the fridge, coffee maker, and toaster weren’t all fighting for power. Now he can make breakfast without tripping a breaker.

Outside, we upgraded the lanai lighting with weatherproof LED fixtures and swapped the outlets for GFCIs rated for coastal exposure. You could see the difference right away — clean, bright, and safe.

Step 6: Planning Ahead

Mark told us he was thinking about a pool heater next year and maybe an EV charger after that. We planned ahead. Ran a spare conduit from the new panel to the garage, left room for two extra breakers, and labeled them “Future Use.”

That’s the beauty of doing upgrades in stages. You take care of safety now but make it easy to add things later. We also made sure the panel had a clear spot for a generator interlock if he ever wants backup power.

Step 7: Final Testing

Before we wrapped up, we tested everything under load — AC, dryer, water heater, lights — all at once. No dips, no flickers. Outlets stayed cool.

We used the thermal camera on every connection point, just to be sure. All good. Then we cleaned up, vacuumed, wiped down the panel, and left a printed layout of every circuit for Mark’s records.

He said, “Feels like this house got twenty years younger.” We just laughed. “You should see what we pulled out of your panel.”

The Outcome

The whole job took about four days. Cost was roughly half of what a full rewire would’ve been. Now he’s got a safe, grounded, modern system — and the option to expand later.

It’s quiet, it’s stable, and it’s up to code.

We stopped by again a few weeks later for a small outdoor project, and Mark said, “My wife doesn’t even notice the lights flicker anymore — because they don’t.” That’s how we know it’s right.

Why We Like Staged Upgrades

Not everyone can swing a total rewire. And that’s okay.

We’ve done dozens of staged upgrades around Naples and Fort Myers — homes in The Moorings, Park Shore, Golden Gate Estates, even some in Bonita. The idea’s always the same: fix what’s critical first, upgrade in steps, and keep the place safe.

You don’t have to do everything at once. You just have to start.

If you’re trying to build a similar step-by-step plan, our guide to prioritizing upgrades explains how we rank safety issues, panel work, and comfort projects for older homes around Fort Myers and Naples.

Wrapping It Up

If your Naples or Fort Myers home was built before 1975, there’s a good chance the wiring, panel, or outlets need attention. You might not see problems yet, but if the lights flicker, outlets feel warm, or breakers trip too often, it’s time to take a closer look.

👉 Call CoHarbor Electric today. We’ll inspect your wiring, give you clear options, and help you plan a staged upgrade that fits your home and your budget. No pressure. Just honest work done right.

Old homes have history. We just make sure the wiring’s ready for another fifty years of it.
