What is whole-house rewiring?
Whole-house rewiring replaces every outdated circuit in a Fort Pierce home — knob-and-tube, aluminum branch, or cloth wiring — with modern grounded copper. Call (772) 218-3629, Mon–Sat 9:00–18:00, and tell us your wiring type, which circuits trip or flicker, and whether walls are already open for renovation.
Start with the wiring itself, not the panel. Old house rewiring in Fort Pierce is old wiring replacement for every circuit in the home: whole house rewiring — knob-and-tube, aluminum branch wiring, or cloth wiring — with a modern wiring system in grounded copper, sized for the loads a home carries today. That provider’s first step is a wiring assessment, room by room and circuit by circuit. Callers often ask about a full house rewire and how long the work takes; both answers depend on what the assessment finds, including whether you can stay in the home while rooms are done in phases. In short, it is obsolete wiring replacement on a whole-home scale, plus the panel work the assessment calls for.
Three wiring types drive most rewiring jobs in Fort Pierce: knob-and-tube (early wiring, no ground, separate hot and neutral through ceramic knobs and tubes), aluminum branch wiring (mid-1960s to mid-1970s, expands and contracts more than copper, loosens connections over time), and cloth wiring (insulation that can become brittle with age). Each type has its own replacement or repair page — knob-and-tube replacement and aluminum wiring repair — because each has its own search, its own risk, and its own repair options. This page covers whole-house rewiring in general; the knob-and-tube and aluminum pages go deeper on each wiring type.
Signs you need rewiring, not just repair
- You have knob-and-tube, cloth, or aluminum branch wiring, found by an assessment, an inspector, or an insurer.
- Breakers trip repeatedly, or lights flicker across the whole house, not just one room.
- Outlets are ungrounded (two-prong), or grounded outlets test as ungrounded.
- An insurer or inspector flagged the wiring type, or a sale is conditional on wiring work.
- Wiring is exposed, brittle, or damaged in an attic, crawlspace, or basement.
- You are renovating, adding major loads (EV, pool, large AC), and the existing wiring cannot carry them safely.
- A warm panel, burning smell, or scorch marks are present — if so, see the emergency page first, not this page.
Options compared: full rewiring, partial rewiring, or repair?
| Option | When it fits | When it does not fit | Key limit |
|---|---|---|---|
| Full rewiring | Widespread old wiring type, insurer/inspection flag, renovation | Single faulty circuit with modern wiring elsewhere | Largest scope; phased, with wall repair |
| Partial rewiring | Old wiring in one area (attic, addition, one floor), rest modern | Old wiring throughout the home | Leaves old wiring in other areas |
| Aluminum repair (pigtailing / COPALUM-type) | Aluminum wiring, connections loosening, full rewiring not yet planned | Knob-and-tube, cloth, or widespread damage | Fixes connections, not the wiring type itself |
| Repair (single circuit) | Single faulty circuit, modern wiring, good panel | Wiring-type problem, repeated whole-house faults | Does not fix wiring type |
Diagnosis first, rewiring second. A wiring assessment shows wiring type, condition, and scope — room by room, circuit by circuit — before a price is given. A provider who recommends full rewiring without an assessment, or who recommends a single-circuit repair for a whole-house wiring-type problem, has not done the assessment.
How rewiring runs, step by step
Infographic: Rewiring process timeline
- Wiring assessment. Check wiring type, condition, panel, and scope, room by room and circuit by circuit. That assessment decides full vs partial rewiring, and whether panel work is part of the job.
- Phased plan and permit. Order the work room by room or circuit by circuit, file the permit, and plan daily power restoration, dust, and wall repair scope before work starts.
- Replacement. Replace circuits one by one, with new copper wiring, grounded outlets, and circuits sized for today's loads. Wall openings are kept as small as access allows, but rewiring does involve wall work — a provider who promises “no wall damage at all” has not explained access honestly.
- Inspection and handover. Inspector visits, panel directory is handed over, and wall repair scope is explained. Keep the directory — it is what the next person needs to understand your panel and circuits.

Cost and what changes the price
No honest quote exists before someone has seen your wiring. The figure moves with house size and circuit count, wiring type, access through attic, crawlspace, and finished walls, panel work, outlet and fixture count, and permit and inspection coordination. Ask for those factors itemized in a written price after a wiring assessment, and ask whether wall repair is inside it.

Time, safety, permits, and local rules
Time required: rewiring time depends on house size, wiring type, access, and whether the home is occupied during work. A provider should give a phased plan — room by room, or circuit by circuit — with power restored each day where possible, rather than a single time promise that ignores access. Ask for the phasing in writing, and for daily power restoration, before work starts.
Safety: do not open the panel interior, do not hold a breaker on, and do not cover knob-and-tube wiring with insulation — a general safety rule, not a how-to guide. If the panel is warm, buzzing, or smells burnt, see the emergency page first. Old wiring that is brittle, exposed, or damaged should not be left in place just because it “still works” — a wiring assessment, not a visual guess, decides that.
Permits, as a general rule: Florida Building Code 105.1 requires a permit before installing, altering, or replacing a regulated electrical system, with an application to the building official first. Whether the City of Fort Pierce or St. Lucie County handles your permit depends on your exact address. Insurer requirements for knob-and-tube, aluminum, and cloth wiring vary by carrier — ask your insurer what it requires, and ask a provider what documentation it will give you for the insurer. As a rough guide, Fort Pierce city is largely served by Fort Pierce Utilities Authority (FPUA) and outside the city largely by Florida Power & Light (FPL), but which utility serves your exact address is settled by your exact address.
Local considerations: older homes in Downtown and Lincoln Park are more likely to have knob-and-tube, cloth, and mid-century panels, which makes rewiring and panel follow-up more likely. Homes built in the aluminum-wiring period (mid-1960s to mid-1970s) exist across Fort Pierce, not just in one area — a wiring assessment, not a build-date guess, shows whether aluminum wiring is present. Coastal homes on Hutchinson Island and South Beach face salt-air corrosion, which can affect panels and outdoor service equipment as well as wiring.
Seasonal considerations and DIY vs hiring
Rewiring is usually planned around a renovation, a sale, or an insurer flag, and summer AC load often exposes weak wiring first. It is not a DIY job — panel work, permits, and inspection are involved — but noting your wiring type, tripping circuits, and any flags helps scope the job. See the signs your house needs rewiring.

How a rewire is phased, and what happens to the walls
A full rewire rarely happens in one pass. Work usually runs room by room, circuit by circuit, so the home is not opened up all at once. A partial rewire covers only the rooms or circuits that need it, such as a kitchen or an addition, while the rest of the home keeps its existing wiring. Ask which rooms are included and in what order, since that order decides how long each part of the home is disrupted.
Openings in drywall are part of the work, and they are usually kept small and left ready for patching and painting. Ask before work starts who patches the openings and who paints, so there is no surprise at the end. Grounding is added to two-prong circuits as part of the new wiring, which is what lets modern three-prong outlets and surge-sensitive equipment work as intended.
What rewiring work looks like
Related services and areas
Rewiring often follows or precedes other services. A panel check may lead to panel upgrade if capacity is the cause. A single faulty circuit may stay as electrical repair, not rewiring. Knob-and-tube and aluminum detail go on the knob-and-tube and aluminum wiring pages. An unsafe problem is an emergency first, not a rewiring sale.
Rewiring is needed across Fort Pierce, including Downtown, Lincoln Park, and Fort Pierce South. See the service areas hub for the full list, and tell us your town or ZIP when you call.
Staying in the home during a rewire
Most households stay in the home while a rewire runs, because work is phased room by room with power restored to finished rooms each day where the plan allows. Ask which rooms lose power on which days before work starts. The signs your house needs rewiring guide covers what an assessment looks at first.
Age, panel upgrades, and the sale or insurance question
Age alone does not decide a rewire: wiring type, condition, and what an assessment finds circuit by circuit set the scope, and repeated blown fuses or discolored, warm, or sparking outlets push hardest toward an assessment. A panel upgrade alone does not fix bad wiring. For inspection and insurance angles, see our 4-point inspection guide.
Frequently asked questions: whole-house rewiring in Fort Pierce
How do I know if my Fort Pierce home needs rewiring?
Signs include knob-and-tube or cloth wiring, aluminum branch wiring, frequent tripping, flickering across the house, a warm panel, or an insurer or inspector flag. A wiring assessment — not a guess from house age alone — shows whether rewiring, panel work, or repair fits your home.
What is knob-and-tube wiring?
Knob-and-tube is an early wiring method with separate hot and neutral wires run through ceramic knobs and tubes, usually with no ground. It was not made for modern loads, insulation, or grounded outlets, and it is often flagged by insurers and inspectors when it is found in a home.
What is wrong with aluminum wiring?
Aluminum branch wiring, used in some homes from the mid-1960s to the mid-1970s, expands and contracts more than copper, which can loosen connections over time. Loose connections can heat up at outlets and switches. Repair options exist, but full rewiring is the complete solution where aluminum wiring is widespread.
How much does whole-house rewiring cost in Fort Pierce?
No one can give you an honest Fort Pierce rewiring number without seeing your home first. The written price follows a wiring assessment and reflects house size, wiring type, access, panel work, outlet and fixture count, and permit and inspection coordination. Ask for that price itemized, and ask whether wall repair is inside it.
How long does rewiring take?
Rewiring time depends on house size, wiring type, access, and whether the home is occupied during work. A provider should give a phased plan — room by room, or circuit by circuit — with power restored each day where possible, rather than a single time promise that ignores access.
Do I have to move out during rewiring?
Not always. Many rewiring jobs are phased so that power is restored each day, but dust, wall openings, and noise are part of the work. A provider should explain phasing, daily power restoration, and wall repair scope before work starts, so you can plan around it.
Does rewiring include a panel upgrade?
Often, but not always. If the panel is undersized, full, or flagged, panel work is part of the job. If the panel is in good condition with enough capacity, rewiring may use the existing panel. A wiring assessment and a load calculation together show which combination fits.
Do I need a permit for rewiring in Fort Pierce?
As a general rule, the Florida Building Code requires a permit before installing, altering, or replacing a regulated electrical system, with an application to the building official first. Whether the City of Fort Pierce or St. Lucie County handles your permit depends on your exact address.
Will rewiring damage my walls?
Openings in drywall are part of a rewire, but they are usually kept small and placed where they reach the most wiring with the least cutting. Ask before work starts who patches the openings and who paints afterward, since those two jobs are sometimes handled separately. A provider should also tell you the order of rooms, so you know which parts of the home are disrupted first and for how long.
