What homeowners say
Vesta’s read
Kostantino is the electrician designers and builders keep coming back to, and the reviews explain why: they execute cleanly and they think. A designer credits them with inventive solutions on projects that stump most electricians; homeowners describe faults that stumped two other companies diagnosed and fixed the same day. The range is unusually wide — kitchen and bath renovation wiring on one job, switches for industrial factory panels sourced fast to keep a build on schedule on another, plus EV chargers and commercial work. Communication earns its own praise, from the helpful person answering the phone to clear arrival updates. A lone older missed-callback is the only blemish. The uncracked problem is the natural brief — this is who designers hand the jobs that have already defeated somebody.

What to check before you hire
Vesta’s plain checklist for electricians. General guidance about the trade — not a claim about this business.
Confirm the CT license and the permit
Electrical work runs under a Connecticut E-class license, and most jobs need a permit and inspection. Both protect your home and your insurance.
Don't shop on price alone
The cheapest panel swap or rewire can skip grounding, AFCI/GFCI protection, or proper load math. Ask exactly what is included to code.
Name the scope
Panel size in amps, circuits added, fixture vs. rough-in work, and who patches the walls should all be written down before work begins.
Match the pro to specialty work
EV chargers, generators, and solar tie-ins each have their own requirements. Confirm hands-on experience with your specific job.
