Best Electrical in Largo, FL — 29 Vetted Contractors

Yes. Panel replacements and upgrades require a permit through the City of Largo Building Services Division, and the work needs to pass inspection before the panel is energized for use. A licensed contractor will typically pull this for you as part of the job — if a quote doesn't mention a permit for panel work, ask why.

It's worth having checked, not necessarily worried about. Aluminum branch wiring was widely used in Florida homes built roughly 1965-1973 and the connection points can loosen over time in a way copper doesn't, which the Consumer Product Safety Commission has documented as a fire hazard. A licensed electrician can inspect your panel and outlets for signs of overheating and recommend either CO/ALR-rated devices or COPALUM crimping — often cheaper than a full rewire.

Search the contractor's name or license number at myfloridalicense.com for a state Certified Electrical Contractor license, or check with the Pinellas County Construction Licensing Board (PCCLB) for a local Registered Electrical Contractor competency card — both cover Largo. Never rely solely on a business card or truck lettering.

In Pinellas County, a manual transfer switch install typically runs $500-1,200, while an automatic standby generator with transfer switch (including the generator unit itself) runs $6,000-12,000+ depending on size. Given how often hurricane season knocks out power in this area, it's one of the more commonly requested jobs from June through November.

For Largo, yes — the Tampa Bay area consistently ranks among the highest lightning-strike-density regions in the U.S. per NOAA/National Weather Service data. A whole-house surge protective device installed at the panel runs roughly $300-600 and protects everything downstream, which is cheaper than replacing a fried AC control board or set of appliances after a nearby strike.

A Level 2 (240V) home charger install generally runs $600-1,800. The low end assumes your existing panel has spare capacity; the high end applies if you need a panel upgrade or a long conduit run to the garage. Get a load calculation as part of the quote — it determines which end of that range you land on.

For a full rewire of a 1,500-2,500 sq ft home, expect $8,000-20,000. Homes with open attic and crawlspace access (common in single-story Largo ranch homes) run cheaper than two-story homes with finished ceilings, where crews have to open and patch drywall to fish new wire.

Routine residential electrical permits through the City of Largo Building Services Division are often approved within a few business days for straightforward work like panel upgrades, though it can stretch longer during peak storm-season demand. Ask your contractor for a realistic timeline before scheduling the work date.
