Hamilton Electric in Baltimore: Licensed Service for Residential Panel Upgrades and Code-Compliant Rewiring
Hamilton Electric is a licensed electrical contractor serving Baltimore homeowners and small commercial properties with panel replacements, circuit additions, and full rewiring jobs that require city permits and inspection sign-off.
What Hamilton Electric actually is
A full-service electrical operation focused on jobs that demand Maryland licensing and Baltimore Department of Housing inspection approval. This rules out simple outlet swaps or fixture replacements and targets the work homeowners cannot do themselves: upgrading from 100-amp to 200-amp service, adding new circuits to accommodate heat pumps or EV chargers, and rewiring older rowhouses with knob-and-tube or aluminum wiring. The company handles the permit paperwork and coordinates inspections with the city.
Services and pricing
Hamilton Electric charges between $85 and $110 per hour for labor on scheduled calls; emergency calls (outside 7 a.m. to 5 p.m. weekdays) run $150 per hour with a two-hour minimum. Panel upgrades range from $1,800 to $3,200 depending on whether the existing mast and conduit can be reused; full house rewiring runs $8,000 to $15,000 for a typical 1,200-square-foot Baltimore rowhouse. A 240-volt circuit for an EV charger (labor only, not equipment) costs $600 to $900. All work includes a walk-through estimate at no charge; the company pulls permits and files for inspection as part of the job. Pricing should be confirmed directly, as labor rates can shift seasonally.
How it compares to other Baltimore electricians
Sparks Electric, also licensed in Baltimore, charges $95 to $120 per hour and tends toward larger commercial jobs; their residential work skews toward new construction rather than retrofit panel work. Choose Sparks if you need coordination with builders or commercial insurance requirements. Reliable Electric offers flat-rate pricing ($450 to $700 for common jobs like outlet installation) but does not handle permit-required work; use Reliable for small repairs and diagnostic calls. Hamilton Electric sits between them: licensed for code work, priced for homeowner budgets, and willing to take on the administrative load of city permits.
Who it suits and who it does not suit
Hamilton Electric suits owners of pre-1950 rowhouses with aging service who need Baltimore inspection compliance, and anyone installing 240-volt equipment (EV chargers, heat pump outdoor units, electric ranges). It also works for landlords managing multi-unit buildings where electrical code enforcement is strict. The company does not do emergency calls for downed power lines or utility-side work; those go to BGE. It also does not prioritize same-day service for non-emergency requests, so plan ahead.
What the first visit involves
Call for a phone consultation and describe the job: panel upgrade, new circuit, rewiring scope, or appliance hookup. The estimator schedules a visit (typically within three to five business days) and walks the panel, checks existing wiring, and discusses code requirements specific to Baltimore. If a permit is needed, Hamilton Electric files it and quotes a timeline (usually two to three weeks for city review). You pay nothing upfront; billing happens after inspection approval and job completion.
Hours, parking, and logistics
Hamilton Electric operates Monday through Friday, 7 a.m. to 5 p.m., with emergency rates after hours and on weekends. They are based in Canton and service Baltimore proper and inner ring suburbs. Parking at your home is your responsibility; electricians will need access to the panel (usually in a basement, crawlspace, or exterior wall) and to circuit locations. Most jobs require the homeowner to be present during the first estimate and final inspection; mid-job site access varies depending on scope.
Hamilton Electric earns its place in the Baltimore guide because it removes the friction of code compliance from a job that most homeowners cannot tackle alone and many local electricians avoid due to permit complexity.
