Why Old Wiring Is Dangerous
Many homes built before 1970 in Atlanta—particularly in historic neighborhoods like Virginia-Highland, Inman Park, and East Atlanta—still use original knob-and-tube or aluminum wiring. These systems were safe for their era but are genuinely dangerous today. Knob-and-tube wiring features individual cloth-wrapped conductors suspended by porcelain knobs and tubes—there's no ground conductor. The cloth insulation deteriorates over 60+ years, becoming brittle and cracked. Modern appliances draw 3–5 times the load these wires were designed for; overheating insulation creates fire risk.
Aluminum wiring (common in 1970s–1980s homes) is worse. Aluminum oxidizes at connection points—outlets, switches, breakers—creating resistance and heat. This oxidation causes connections to loosen over time, increasing fire risk dramatically. Insurance companies recognize these hazards. Many refuse coverage on homes with knob-and-tube or aluminum wiring; others require expensive endorsements or demand rewiring before coverage continues. Selling a home with undisclosed old wiring can trigger inspection failures and significant price reductions.
Modern Romex cable (plastic-sheathed copper, introduced in the 1960s) includes a ground conductor, protective plastic sheathing, and meets current NEC standards and Atlanta Building Code. It supports 200A service, 20A circuits per outlet, and ground-fault and arc-fault protection that knob-and-tube simply cannot provide. Replacing old wiring with modern copper eliminates fire risk, restores insurance coverage, and prepares your home for decades of safe operation.
Our Comprehensive Rewiring Process
We begin with a thorough inspection: accessing attics, crawlspaces, and basements to identify all wiring types (knob-and-tube, aluminum, copper), testing connections with a multimeter, documenting the existing panel (fuse or breaker, amperage, grounding condition), and sketching a detailed floor plan showing all circuits and breaker assignments. From this assessment, we create a phased rewiring plan tailored to your home's layout and your preferences for minimizing disruption.
We then obtain Atlanta building permits, coordinate with the city inspections office, and schedule work. Most full rewires happen in phases: we might rewire bedrooms and living areas in week one while maintaining kitchen and bathroom power, then complete bathrooms and kitchen in week two. This allows you to stay in your home if you choose, though we always recommend having a contingency plan (hotel, family visit) because the work is genuinely disruptive.
During installation, we pull new 12/2 or 14/2 Romex cable through existing wall cavities, attic pathways, and conduit runs—minimizing drywall cutting. Where cavities are blocked, we cut small openings, thread cable through, and patch drywall. Old knob-and-tube and aluminum wiring is disconnected and removed. We upgrade the main panel from fuses to a modern breaker panel with 40+ available slots, full grounding, and 200A service capacity. Every outlet, switch, and breaker is tested before final sign-off.
The final step is Atlanta City Inspections verifying code compliance. Once passed, you receive a Certificate of Electrical Compliance—this document is essential for insurance coverage and future home sales. Your new wiring carries a lifetime workmanship warranty and is covered by insurance once the certificate is filed.
Cost Breakdown and Timeline
Typical Whole-House Rewire: $8,000–$20,000
Permit, inspection, new panel, Romex throughout, outlets/switches/breakers, minimal drywall patching
Complex layout, multiple attics, basement, and crawlspace runs; more drywall patching required
Multiple stories, finished basements, complicated attic layouts; significant drywall repair
Timeline and Phases
- • Inspection & planning: 1 week (includes permit application)
- • Rewiring execution: 2–4 weeks depending on home size (phased to maintain power where possible)
- • Final city inspection: 1–2 weeks scheduling availability
- • Drywall patching: 1–2 weeks if a contractor handles finishing (optional; we can refer contractors)
- • Total duration: 4–8 weeks from start to certified completion
The Real Return on Investment
A whole-house rewire costs $8,000–$20,000 upfront, but the returns are substantial. First, insurance coverage: many insurers refuse or charge premiums on homes with knob-and-tube or aluminum wiring. After rewiring and certification, your premium may drop $100–$300 annually—recouping the investment in 3–7 years. Second, resale value: homes with certified modern electrical systems command 3–5% higher prices; buyers and lenders demand proof of safe systems. A $400,000 home sale might increase by $12,000–$20,000 with a Certificate of Electrical Compliance in hand.
Third, safety: you eliminate real fire risk from deteriorated insulation and oxidized aluminum connections. Fourth, capability: a modern 200A panel with ground-fault protection, dedicated circuits, and future expansion capacity supports EV charging, heat pumps, induction cooking, and whatever technologies emerge over the next 50 years. Homes throughout Atlanta—from Buckhead renovations to Decatur historic homes, Virginia-Highland revivals to Dunwoody upgrades—benefit enormously from fresh electrical infrastructure.
If you have knob-and-tube or aluminum wiring, rewiring isn't optional—it's an investment in safety, insurance compliance, and resale value. We guide you through the entire process, minimize disruption, and deliver a code-compliant system that lasts 50+ years.
