About Us
Serving Wilmington, DE, and New Castle County, DE, with dependable residential and commercial electrical work since 1975.
Founded in 1975 by Dan Delcollo, Delcollo Electric has built a long-standing reputation for dependable electrical work across Wilmington, DE, and New Castle County. What began as a locally focused electrical business has grown into the area’s most trusted, veteran-owned electrical contractor.
For nearly 50 years, we have provided electrical services for residential properties, small commercial facilities, and national companies requiring reliable local support. Our work includes everything from detailed electrical troubleshooting and repairs to service upgrades, lighting installations, and system improvements. We are especially known for solving complex electrical issues that other electricians are unable to locate, which has led to frequent referrals for difficult diagnostic work.
Reliability has always guided how we operate. Calls are answered by live staff, not recordings, and emergency inquiries are handled promptly. We focus on clear communication, accurate diagnostics, and safe execution on every project. Our team understands how disruptive electrical issues can be, which is why we approach every job with care and accountability.
As a licensed, bonded, and insured electrical contractor, we take safety and code compliance seriously. Our commitment to consistent service and technical skill has earned recognition as Best Electrician in New Castle County for 12 consecutive years. From long-time homeowners to growing businesses, our goal remains the same: provide dependable electrical solutions customers can count on.
