About
Delcollo Electric Inc has operated out of Wilmington, DE since 1975, bringing over 50 years of licensed, bonded, and insured electrical contracting experience to commercial and small business properties across New Castle County. Veteran-owned and recognized as Best Electrician in New Castle County by News Journal Readers' Choice for 12 consecutive years, the company serves retail, office, multifamily, mixed-use, warehouse, and light industrial facilities throughout the Wilmington metro, including Newark, Hockessin, New Castle, Middletown, Claymont, and Elsmere. For property managers and facility managers overseeing smaller commercial portfolios, Delcollo Electric provides panel and service upgrades — a core need when aging panelboards and breakers can no longer support evolving tenant power demands. The team handles commercial lighting systems and retrofits, making them a practical option for retail and office landlords looking to reduce operating costs through efficient lighting upgrades. EV charger installation (EVSE) is an increasingly common request across commercial parking facilities and multifamily properties, and Delcollo fields those projects alongside low-voltage and data wiring, surge protection, and HVAC and air conditioner wiring that commercial tenants routinely require. Power distribution troubleshooting and aluminum wiring repairs round out a service menu well-suited to older Wilmington-area commercial buildings where deferred electrical maintenance is common. The firm emphasizes high-level troubleshooting — a differentiator for facility teams dealing with persistent power quality or circuit issues that other contractors have failed to resolve. Free estimates are offered on all projects, and live phone support is available for urgent inquiries. With a four-decade-plus footprint in Delaware's largest city and a strong community reputation, Delcollo Electric is a credible first call for light commercial electrical work in the greater Wilmington market.
