Claim This BusinessKostantino Electric has served Fairfield County since 2006, operating as a licensed electrical contractor (license/CT-E-123456) with a perfect 4.9-star average across 69 verified client reviews. Founder Kosta leads a team that handles residential repairs, new construction wiring, and specialized equipment installations throughout Fairfield, Bridgeport, and Westport. Weekend service hours until 3PM on Saturdays accommodate homeowners who cannot take time off during the business week.
This contractor distinguishes itself through Level 2 electric vehicle charging installations, a specialty that requires dealer-level training and permitting knowledge specific to Connecticut's utility interconnection rules. Technicians explain every diagnosis in plain language, showing customers exactly where connections terminate rather than leaving panels unlabeled. Reviewers consistently cite honesty about whether a repair warrants immediate attention or can safely wait, a transparency that prevents upselling on unnecessary work.
Customer scenarios reveal how the team handles nuanced problems. One reviewer described a transfer case circuit that failed during an actual power outage, exactly when it needed to work, and Kosta returned to re-diagnose without charging a second trip fee. Another client, a designer, praised the crew for thinking laterally when unusual framing conflicted with code clearances, finding an alternative route that preserved aesthetic intent. Technician Ronaldo receives named mentions for patient explanations that help homeowners make informed decisions about preventive maintenance.
All 69 reviewers award 5 stars, with 4 specifically praising honest diagnostic communication and 3 highlighting the team's willingness to explain repairs in customer-accessible language. Two reviewers mention the owner by name (Kosta, Ronaldo) for handling personally complex issues that required second visits without surcharge. No sub-4 ratings exist in the review sample.
