Whole-House Rewiring for Older Sarasota-Bradenton Homes
If your home was built before 1980, there's a decent chance the wiring inside the walls isn't up to today's standards. Maybe it's aluminum branch wiring from the late '60s and '70s — the stuff that loosens at connections over time and creates hot spots. Maybe it's original cloth-wrapped wiring with insulation that's crumbling. Or maybe your home has been added on to three different times and nobody ever upgraded the original circuits to handle the new loads.
I'm Donny McGuire, and I rewire houses across Sarasota and Bradenton. It's a big job, but I've done enough of them to know exactly how to get it done with minimal disruption to your daily life. I'm not going to tear your walls apart if I don't have to.

When a Rewire Is the Right Call
Aluminum Branch Wiring
Homes built between roughly 1965 and 1975 often used aluminum wiring for the branch circuits — the wires that run to your outlets and switches. Aluminum expands and contracts with heat cycling more than copper does. Over time, connections loosen. Loose connections create heat. Heat creates fires. The CPSC has documented that homes with aluminum wiring are 55 times more likely to have a connection reach fire-hazard conditions. A full copper rewire eliminates the risk permanently.
Knob-and-Tube Wiring
Some of the older homes in Sarasota's historic neighborhoods still have knob-and-tube wiring from the early 1900s. It's porcelain insulator-mounted wiring with no ground conductor. It was fine when the heaviest load in the house was a few light bulbs and a radio. It is not fine for modern appliances, and insulation blown over knob-and-tube creates a fire hazard. Most Florida insurance companies will not write a policy on a home with active knob-and-tube wiring.
Major Renovation or Addition
If you're gutting the kitchen, adding a master suite, or doing a major remodel, that's the time to rewire. The walls are already open. Running new wire through open studs is ten times faster and cheaper than fishing it through finished walls. I coordinate with your general contractor on timing so the electrical rough-in happens at the right stage of the project. If you're already doing a big renovation and not rewiring, you're leaving the hardest-to-fix problem behind the new drywall.
Insurance Requirements
Florida insurance companies are getting stricter every year. If your wiring is flagged on a 4-point inspection — aluminum, cloth-wrapped, ungrounded, or just old — they may decline coverage or charge a surcharge that makes the rewire pay for itself in a few years. I work with homeowners regularly who need the rewire done before their insurance renewal deadline. I can usually get it scheduled, permitted, and completed within two to three weeks for a standard-sized home.
The Rewiring Process and Timeline
A whole-house rewire sounds intimidating, but I've done this enough times to keep it organized. Here's the general flow:
Day 1–2: Planning and permit. I map out every circuit in the house, decide on the new panel location if needed, and pull the permit. I walk through the house with you so you know exactly what's happening where.
Day 3–7: Rough-in. I run new copper Romex through the attic, walls, and crawlspace. In Florida homes with concrete slab foundations, most wire runs go through the attic. I use flex bits and fish tapes to route wire through finished walls without opening them up wherever possible. Some access holes are unavoidable — I'll tell you exactly where before I cut anything.
Day 8–9: Panel, devices, and trim-out. New panel goes in (usually a 200-amp upgrade at the same time), all new outlets, switches, and cover plates get installed. GFCI protection where code requires it. Arc-fault breakers on bedroom circuits.
Day 10: Inspection and close-up. County inspector signs off. Any access holes get patched. Your home is now running on modern copper wiring with a panel that can handle the next 30 years.
Total timeline for a typical 3-bedroom home: about two weeks. Larger homes or homes with complex layouts may take a few days longer.
