Sticker shock is real when you start pricing a whole-house rewire. If you’ve searched for house rewiring cost per square foot, you’re already on the right track. In this guide, we break down realistic Florida pricing, what drives the number up or down, and when panel, GFCI, or AFCI upgrades are required. You’ll also see sample budgets for common home sizes and how Del-Air keeps projects safe, code compliant, and on schedule.
What “rewiring” actually includes
Rewiring is more than pulling new cable. A comprehensive project typically includes:
- New branch-circuit wiring to outlets, lights, and fixed equipment.
- New receptacles, switches, and cover plates.
- Bonding and grounding corrections.
- GFCI protection where water is present and outdoors.
- AFCI protection for most living areas to reduce fire risk from arcing.
- Panel and breaker updates if capacity, condition, or safety requires it.
In Central Florida, many homes built before the 1980s still have outdated wiring methods or undersized panels. Rewiring brings your home in line with current safety standards so your devices, EV chargers, and high-efficiency HVAC run reliably.
Average house rewiring cost per square foot
Most Florida homeowners should budget in these ranges for a full rewire:
- Basic range: 4 to 9 dollars per square foot for straightforward, single-story homes with good access.
- Complex range: 9 to 15 dollars per square foot for multi-story homes, plaster walls, tight attics, or extensive patch-and-paint.
Examples:
- 1,200 sq ft home: 4,800 to 10,800 dollars basic, 10,800 to 18,000 dollars complex.
- 1,800 sq ft home: 7,200 to 16,200 dollars basic, 16,200 to 27,000 dollars complex.
- 2,400 sq ft home: 9,600 to 21,600 dollars basic, 21,600 to 36,000 dollars complex.
These figures assume standard copper NM-B cable, code-required GFCI/AFCI protection, device replacements, permits, and typical drywall repairs around device boxes. They exclude major service upgrades, aluminum mitigation, or luxury fixtures.
What drives the price up or down
Every home is unique, but seven factors explain most price differences:
- Size and stories
- More square footage means more circuits and longer wire runs.
- Two stories usually add labor because running cable between floors is harder than in a single-story with attic access.
- Access and structure
- Attics that are tight or obstructed, vaulted ceilings, and masonry walls increase labor time.
- Central Florida attics can exceed 120 degrees in summer, which limits safe work windows and slows production.
- Wall finishes and patching
- Plaster, tile backsplashes, shiplap, or heavy-texture finishes take longer to open and restore than standard drywall.
- Panel capacity and condition
- Old, crowded, or recalled panels often require replacement. Modern homes with EV chargers, heat pumps, and induction ranges benefit from 200-amp service.
- Protective devices and safety upgrades
- GFCI is required in kitchens, bathrooms, garages, outdoors, and laundry areas.
- AFCI is required in most habitable rooms. Adding combination GFCI/AFCI breakers or outlets impacts cost.
- Aluminum wiring or DIY legacy work
- 1960s–1970s homes may have aluminum branch circuits. Full replacement or approved mitigation adds materials and labor.
- Permits and inspections
- Municipal permit fees vary by jurisdiction and project scope. Inspections confirm code compliance and safety.
Cost components line by line
Understanding the bill helps you prioritize and compare bids:
- Labor: 40 to 60 percent of total cost. Skilled labor is the largest driver because fishing cable, labeling, and testing are time-intensive.
- Materials: 20 to 35 percent. Copper cable, boxes, staples, wire connectors, receptacles, switches, and plates.
- Panel and breakers: 10 to 25 percent if upgraded. AFCI/GFCI breakers cost more than standard thermal-magnetic types.
- Patching and finish: 5 to 15 percent depending on how minimally invasive the runs can be.
- Permits and inspections: Flat or sliding, set by the authority having jurisdiction.
Do you always need a panel upgrade?
Not always. If your existing service and panel have adequate capacity, labeling, and clear working space, a full replacement may not be necessary. You will, however, need enough breaker spaces for dedicated kitchen, laundry, bath, and HVAC circuits, plus AFCI and GFCI protection where required. Homes adding EV chargers, pool equipment, or high-load heat pumps often benefit from 200 amps. During our estimate, we calculate connected loads and future plans to right-size the service.
Rewiring vs. partial rewiring
You might not need to touch every room. Strategic approaches include:
- Kitchen and laundry first
- High-usage areas with water exposure. Requires multiple small-appliance circuits, dedicated laundry, dishwasher, disposal, and microwave circuits.
- Bathroom and outdoor circuits
- GFCI upgrades reduce shock risk around water and outside.
- Problem-circuit remediation
- Hot spots, tripping breakers, and aluminum branches targeted first. We can phase remaining rooms over time.
Partial rewires reduce immediate spend, but a full plan keeps future phases efficient and code-aligned.
Planning timeline: what to expect
A typical whole-home project follows this flow:
- In-home assessment and load calculation
- We document devices, appliances, panel capacity, and visible wiring methods.
- Permit and materials staging
- We pull permits, order breakers and panels, and schedule inspection windows.
- Rough-in phase
- Old conductors are abandoned or removed as needed. New home runs are fished with minimal openings.
- Device and trim-out
- Receptacles, switches, and lighting connections are installed, labeled, and tested.
- Inspection and final punch
- We meet inspectors, correct any punch items, and walk you through every new circuit.
Straightforward single-story homes often complete in one to two weeks. Multi-story or plaster homes can take longer.
Code and safety essentials every homeowner should know
Electrical codes are written to reduce fire and shock risk. Key highlights:
- GFCI protection is required in kitchens, bathrooms, garages, outdoors, and laundry areas.
- AFCI protection is required in most living spaces such as bedrooms, living rooms, and hallways.
- Receptacle spacing rules reduce extension cord use and trip hazards.
- Proper grounding and bonding ensure fault currents clear breakers quickly.
Del-Air electricians keep your project aligned with current code and local amendments. We pull permits and meet with inspectors so you do not have to coordinate.
Bundles and add-ons often paired with rewires
Rewiring is the perfect time to add value and safety:
- Whole-home surge protection to guard electronics and HVAC equipment.
- EV charger circuits with proper load calculations.
- LED lighting upgrades, dimmers, and smart switches.
- GFCI and AFCI coverage where missing.
- Smoke and CO detector replacements with hardwired interconnects.
- Outdoor and security lighting for safer entries and yards.
Because our teams handle HVAC, plumbing, and electrical, you get one project manager for cross-trade tasks like smart thermostats, bath fans, and range hood power.
Sample budgets for common Florida home sizes
Use these ballpark figures to start planning. Your final estimate may vary based on access, finishes, and panel needs.
- 1,300 sq ft block home, single story, attic access, drywall: 6,500 to 12,000 dollars. Add 2,000 to 4,000 dollars if upgrading to a 200-amp panel with AFCI/GFCI breakers.
- 1,900 sq ft two-story wood-frame, moderate attic access: 10,000 to 21,000 dollars. Expect additional drywall repair on the first floor.
- 2,400 sq ft home with aluminum branch circuits: 14,000 to 30,000 dollars, depending on full replacement vs. approved mitigation and panel condition.
We build transparent line-item estimates so you can see where every dollar goes.

Red flags and how to evaluate competing bids
When comparing proposals, look for:
- Permit and inspection details clearly included.
- AFCI and GFCI protection listed to current code, not as optional upsells.
- Panel brand and amperage specified, plus space count for future circuits.
- Device counts and locations noted, including tamper-resistant receptacles.
- Patching scope and paint responsibility spelled out.
- Warranty terms and proof of licensing and insurance.
A low bid that omits protection devices or permits often costs more later. Ask each contractor to confirm code compliance in writing.
Minimizing disruption during a rewire
We keep you comfortable and on schedule:
- Phased shutdowns so only active areas are powered down during work windows.
- Daily cleanup, with device holes neatly cut to standard plate sizes.
- Clear communication on any necessary furniture moves and dust protection.
- Temporary lighting or power where reasonable during phases.
You will know each day’s plan before crews arrive.
When a rewire is the safer choice
You likely need a comprehensive rewire if you have:
- Frequent breaker trips or warm outlets.
- Two-prong receptacles with no grounding.
- Visible cloth-insulated or aluminum branch wiring.
- Flickering lights unrelated to utility events.
- DIY splice boxes hidden in walls or attics.
If you are unsure, start with a whole-home electrical inspection. We will document findings and give you a phased plan.
Why Florida homes benefit now
Today’s homes power heat pumps, EV chargers, induction ranges, and whole-home networking. Upgrading wiring and protection reduces nuisance trips, protects electronics from surges, and creates capacity for future projects. In older Central Florida neighborhoods, a modern electrical system also adds resale confidence for buyers and inspectors.

Frequently Asked Questions
How much does rewiring cost per square foot in Florida?
Expect about 4 to 9 dollars per square foot for straightforward homes and 9 to 15 dollars for complex projects. Multi-story layouts, plaster, and panel upgrades increase price.
Do I need a panel upgrade to rewire my house?
Not always. If your panel has capacity, clear labeling, and space for required AFCI/GFCI protection, it may stay. Homes adding EV chargers or large appliances often upgrade to 200 amps.
How long does a whole-home rewire take?
Single-story homes with attic access often finish in one to two weeks. Multi-story or plaster homes can take longer due to fishing and patching needs.
Will my power be off the whole time?
No. We phase work so only the areas being rewired are shut down during that stage. We coordinate any full-house shutdowns and keep them as short as possible.
Can I live at home during the rewire?
Yes, in most cases. We sequence rooms, control dust, and keep essential circuits active when safe. We will outline the plan before work begins.
In Summary
House rewiring cost per square foot depends on access, stories, finishes, and safety upgrades. For Central Florida homes in Orlando, Kissimmee, Winter Haven, and nearby areas, planning 4 to 15 dollars per square foot is realistic. A code-compliant rewire adds safety, capacity, and resale value.
