The system buyers can't see but insurers and inspectors always check — where an old panel can quietly kill a policy.

Modern electrical means no tripping breakers when the AC and the dryer run together, enough capacity for an EV charger and a future solar array, and the quiet safety of grounded, GFCI-protected circuits. It's invisible when it's right — and impossible to ignore when it's wrong.
Electrical is invisible on a tour but central to the inspection. An updated panel and service capacity signal a safe, modern home and support the loads buyers now expect. A flagged panel, by contrast, becomes a renegotiation lever or a financing problem.
This is the sharpest insurance edge in the house. Federal Pacific Electric (FPE) and Zinsco panels — plus aluminum branch wiring and knob-and-tube — are flagged by carriers as fire risks. Many will not write or renew a policy until the panel is replaced. No policy means no mortgage, which means no closing.
FPE / Zinsco can block a policy outright
Florida's lightning capital status and frequent grid hits make whole-home surge protection genuinely useful here, and coastal salt air corrodes panels and connections faster. Storm-season outages also drive interest in transfer switches and generator or battery readiness — capacity buyers increasingly ask about.
Lightning + salt = real surge/corrosion risk
A look at the kind of electrical our in-house trades scope and self-perform — shot for value, not vanity.
Electrical is the system nobody photographs and everybody's inspector examines. We scope it through insurability first, because in Florida a single obsolete panel can stop a sale cold — not because the lights don't work, but because no carrier will insure it. The brokerage question isn't 'is it on,' it's 'will it pass underwriting.'
Certain electrical panels are effectively uninsurable. Federal Pacific Electric (FPE) Stab-Lok panels and Zinsco panels have well-documented failure-to-trip histories and are treated by many carriers as fire hazards — they'll decline or non-renew until the panel is replaced. The same goes for aluminum branch wiring and any surviving knob-and-tube.
Because a financed buyer can't close without bound insurance, a flagged panel isn't a cosmetic issue — it's a transaction-ender. Replacing it ahead of a listing turns a deal-killer into a non-issue and a documented selling point.
| Condition | Concern | Typical outcome |
|---|---|---|
| FPE / Zinsco panel | Failure-to-trip fire risk | Decline / non-renew until replaced |
| Aluminum branch wiring | Connection overheating | Remediation or pigtailing required |
| Fuse box / 60–100A service | Undersized for modern loads | Upgrade expected; insurer scrutiny |
| Missing GFCI/AFCI | Shock / fire protection gap | Inspection callout; cheap to remedy |
Typical underwriting behavior — carriers and homes vary. The pattern is consistent: an obsolete panel is an insurability problem first.
Florida is the lightning capital of the country, which makes whole-home surge protection a practical upgrade rather than a luxury, and gives buyers a real reason to value it. Coastal salt air also corrodes panels, breakers, and connections faster than inland, so near the water we look harder at panel condition and weatherproofing.
Modern capacity matters for where this market is going: EV chargers, solar interconnection, and battery backup all need service headroom. A 200-amp service with a clean, current panel is the platform every other performance upgrade plugs into.
