Whole-Home Electrical Rewiring Services in Boca Raton & South Florida

Is your home’s electrical wiring outdated, damaged, or unsafe? HMG Electrical provides professional whole-home rewiring services throughout Boca Raton, Deerfield Beach, Delray Beach, and all of South Florida. As a licensed and insured electrical contractor (FL EC-13010199), we specialize in replacing old, hazardous wiring with modern, code-compliant electrical systems that protect your family and home.

Homes built before the 1980s often contain outdated wiring that can’t safely handle today’s electrical demands. From aluminum wiring and knob-and-tube systems to deteriorating cloth-covered cables, old wiring is the leading cause of residential electrical fires in the United States. A professional whole-home rewire eliminates these hazards while dramatically increasing your home’s capacity, safety, and value.

Signs Your Home Needs Electrical Rewiring

Many homeowners don’t realize their wiring is dangerous until a problem occurs. Watch for these critical warning signs that indicate your home may need rewiring:

• Frequent circuit breaker trips — If breakers trip regularly, your wiring can’t handle your electrical load. This is especially common in older homes with 60-amp or 100-amp service panels.
• Flickering or dimming lights — Lights that flicker when appliances turn on indicate undersized wiring or loose connections that create arc-fault hazards.
• Discolored or warm outlets — Scorch marks, brown discoloration, or warmth around outlets and switches signal dangerous overheating inside the walls.
• Burning smell with no visible source — An electrical or plastic burning smell inside walls is an emergency. Turn off the circuit immediately and call a licensed electrician.
• Two-prong (ungrounded) outlets — Homes with only two-prong outlets lack grounding, leaving you unprotected from electrical shock and making surge protectors ineffective.
• Aluminum or knob-and-tube wiring — Both wiring types are known fire hazards. Many insurance companies refuse to cover homes with these systems or charge significantly higher premiums.
• Frequent blown fuses — If your home still uses a fuse box instead of a circuit breaker panel, the entire system is likely 50+ years old and overdue for replacement.
• Sparking outlets — Visible sparks when plugging in devices indicate arcing, which can ignite insulation or wall materials.
• Home is 40+ years old and has never been rewired — Electrical wiring has a functional lifespan of 30-40 years. If your home was built before the 1980s and still has original wiring, it should be professionally inspected.

Don’t ignore these warning signs. Electrical fires cause an estimated 51,000 home fires annually in the U.S., resulting in nearly 500 deaths and $1.3 billion in property damage. Early rewiring prevents catastrophic outcomes.

Types of Hazardous Wiring We Replace

South Florida’s housing stock includes homes from every era, and we regularly encounter — and safely replace — all types of outdated wiring systems:

Knob-and-Tube Wiring (Pre-1940s)

Knob-and-tube (K&T) was the standard wiring method from the 1880s through the 1930s. It uses ceramic knobs and tubes to run individual copper conductors through wall cavities. While functional when installed, K&T wiring lacks a ground wire, can’t handle modern electrical loads, and becomes extremely dangerous when insulation is added around it (trapping heat). Most insurance companies will not issue or renew policies on homes with active knob-and-tube wiring.

Aluminum Wiring (1965-1973)

During a copper shortage in the late 1960s and early 1970s, builders used single-strand aluminum wiring as a cheaper alternative. Aluminum expands and contracts more than copper when heated, causing connections to loosen over time. This creates dangerous hot spots at outlets, switches, and junction boxes. The U.S. Consumer Product Safety Commission (CPSC) found that homes with aluminum wiring are 55 times more likely to have fire-hazard conditions at outlets than homes with copper wiring. Many South Florida homes built during this era — including throughout Boca Raton, Deerfield Beach, and Delray Beach — contain aluminum wiring that should be replaced.

Cloth-Covered Wiring (1920s-1960s)

Before modern thermoplastic insulation (Romex/NM cable), electrical wiring was insulated with cloth fabric coated in rubber. Over decades, this cloth insulation dries out, cracks, and crumbles away, exposing bare copper conductors inside walls. Cloth-covered wiring also lacks a ground wire and is often found in homes with outdated 60-amp fuse panels. When the insulation deteriorates, bare wires can contact wood framing, metal pipes, or other conductors — creating short circuits and fire hazards.

Backstabbed Connections

Even relatively modern homes (1980s-2000s) may have “backstabbed” wire connections at outlets and switches, where wires are pushed into spring-loaded slots instead of being securely wrapped around screw terminals. These push-in connections loosen over time and are a common source of arcing and overheating. During a whole-home rewire, we replace all backstabbed connections with proper screw-terminal wiring for lasting reliability.

Our Whole-Home Rewiring Process

A whole-home rewire is a significant project, but our systematic approach minimizes disruption to your daily life. Here’s what to expect when you choose HMG Electrical for your rewiring project:

Step 1: Comprehensive Electrical Inspection

We begin with a thorough inspection of your entire electrical system — wiring, panel, outlets, switches, junction boxes, and grounding. We document the current wiring type, identify all hazards, assess your panel’s capacity, and evaluate your home’s electrical needs. You’ll receive a detailed written report of our findings along with our professional recommendations.

Step 2: Custom Rewiring Plan

Every home is different. We create a customized rewiring plan that accounts for your home’s layout, your family’s electrical needs, future capacity requirements, and local building codes. This plan includes the number and placement of circuits, outlet and switch locations, dedicated circuits for high-draw appliances (HVAC, kitchen, laundry, EV charger), and any panel upgrade requirements. We walk you through the plan so you know exactly what to expect.

Step 3: Permits & Code Compliance

Whole-home rewiring requires permits from your local building department. We handle all permit applications, plan submissions, and scheduling of inspections. In Boca Raton, permits are obtained through the City of Boca Raton Building Division. In Deerfield Beach, through the city’s Building Division on Hillsboro Boulevard. We ensure your project complies with the current National Electrical Code (NEC) and all Florida-specific requirements.

Step 4: Systematic Rewiring

Our electricians work room by room, replacing all old wiring with new copper NM-B (Romex) cable rated for the appropriate amperage. We install new outlets (including GFCI protection in kitchens, bathrooms, garages, and outdoor areas), new switches, new junction boxes, and arc-fault circuit interrupter (AFCI) breakers as required by current code. We use careful drywall access techniques to minimize wall damage — in many cases running wire through attics, crawl spaces, and existing pathways to reduce the number of wall openings.

Step 5: Panel Upgrade (If Needed)

Most whole-home rewires include a panel upgrade to a modern 200-amp service. Your old fuse box or undersized breaker panel is replaced with a new, code-compliant panel that can safely handle your home’s full electrical capacity. We also install a proper grounding system and whole-home surge protection.

Step 6: Testing & Inspection

After rewiring is complete, we perform comprehensive testing of every circuit, outlet, switch, and connection. We verify proper grounding, correct polarity, GFCI and AFCI protection, and appropriate load distribution across circuits. We then schedule the required municipal inspection to verify full code compliance. You’ll receive a signed certificate of inspection for your records and your insurance company.

Step 7: Drywall Repair & Cleanup

We patch and repair all wall openings created during the rewiring process. While we include basic drywall patching, we can also coordinate with trusted drywall and painting contractors for a seamless finish if desired. Your home is left clean and ready to enjoy.

Whole-Home Rewiring Cost in South Florida

The cost of rewiring a home depends on several factors, including the home’s size, the number of circuits needed, accessibility of the wiring pathways, and whether a panel upgrade is included. Here are typical price ranges for South Florida rewiring projects in 2025:

Panel upgrade add-on: If your home needs a panel upgrade as part of the rewire (most do), expect an additional $2,500 – $4,500 for a 200-amp panel. See our panel upgrade page for detailed pricing.

Additional cost factors:

• Two-story homes cost 15-25% more than single-story homes due to additional labor for vertical wire runs
• Concrete block construction (common in South Florida) may require additional labor for running conduit on exterior walls
• Finished vs. unfinished walls — Homes with accessible attics and crawl spaces require less drywall work
• Number of circuits — Modern code requires more dedicated circuits than older homes had (kitchen, bathroom, laundry, HVAC, outdoor)
• Smart home pre-wiring — Adding structured wiring (Cat6 ethernet, low-voltage) during a rewire is cost-effective since walls are already open

Financing available. We understand that a whole-home rewire is a significant investment. Ask about our financing options to make the project affordable with manageable monthly payments.

Frequently Asked Questions About Whole-Home Rewiring

How long does a whole-home rewire take?

Most residential rewiring projects take 5 to 10 business days depending on the size and complexity of your home. A small single-story home (under 1,500 sq ft) may be completed in 4-5 days, while a larger two-story home (2,500+ sq ft) typically takes 7-10 days. This timeline includes the electrical work, testing, and inspection scheduling. Drywall patching and painting are additional time. We provide a specific timeline estimate during your consultation so you can plan accordingly.

Do I need to move out during rewiring?

In most cases, you do not need to move out. We work room by room, keeping as much of your home energized as possible throughout the project. You may experience temporary power interruptions to specific areas as we work on them, but we coordinate with you to minimize inconvenience. We typically keep the kitchen and at least one bathroom fully operational each day. For very large or complex projects, we may recommend being out of the home for 1-2 days during the main panel changeover.

Will rewiring damage my walls?

Some wall openings are necessary to route new wiring, but we use minimally invasive techniques to keep wall damage to a minimum. We route wiring through attic spaces, crawl spaces, and existing pathways wherever possible. Strategic access holes are kept small and are patched after the work is complete. In concrete block homes (common in South Florida), we may run some circuits in surface-mounted conduit rather than opening block walls, depending on the situation and your preference. Our goal is always to minimize cosmetic disruption while ensuring a safe, code-compliant installation.

Does rewiring require a permit?

Yes. Whole-home rewiring requires an electrical permit from your local building department. In Boca Raton, permits are obtained through the City of Boca Raton Building Division. In unincorporated Palm Beach County, through the county’s Building Division. We handle all permit applications and schedule all required inspections. Working without permits is illegal, voids insurance coverage, and creates liability issues when selling your home. Always use a licensed contractor who pulls proper permits.

Will rewiring my home increase its value?

Yes, significantly. A whole-home rewire increases property value in several ways: it eliminates a major inspection red flag that can kill a real estate transaction, reduces homeowners insurance premiums (especially if removing aluminum or knob-and-tube wiring), ensures the home passes insurance company inspections (required for many carriers in Florida), and gives buyers confidence in the home’s safety. In South Florida’s competitive real estate market, a recently rewired home with a 200-amp panel and modern copper wiring is a strong selling point. The typical return on investment for a rewire is 60-80% at resale.

Can I rewire just part of my home?

Yes — partial rewiring is an option for homeowners who want to address the most critical areas first. We commonly do partial rewires for kitchens (which require multiple dedicated 20-amp circuits), bathrooms (GFCI protection), master bedrooms, and home offices. However, if your home has aluminum wiring or knob-and-tube throughout, we strongly recommend a whole-home rewire for safety and to satisfy insurance requirements. A partial rewire also won’t resolve panel capacity issues or bring the entire system up to current code. We’ll assess your specific situation and provide honest guidance on the best approach.

Will my homeowners insurance go down after rewiring?

In many cases, yes. If your home currently has aluminum wiring, knob-and-tube, or an outdated fuse panel, your insurance premiums may be significantly higher — or your carrier may be threatening non-renewal. After a whole-home rewire with a modern 200-amp panel, many homeowners see insurance premium reductions of $500 to $2,000+ per year. We provide all necessary documentation (inspection certificates, photos, permit closure) that your insurance company needs to adjust your rates. Some homeowners find that the insurance savings alone help offset the cost of the rewire within a few years.

What type of wire do you use?

We use copper NM-B (Romex) cable rated for the appropriate amperage of each circuit — typically 12-gauge for 20-amp circuits and 14-gauge for 15-amp circuits, with 10-gauge or larger for high-draw circuits (ranges, dryers, HVAC, EV chargers). All wire is UL-listed and meets current NEC and Florida Building Code requirements. For outdoor and underground runs, we use appropriately rated UF-B cable or conduit-rated THWN wire. We never use aluminum branch circuit wiring.
