Company History

In May 1967, Augustine "Augie" Calfo and Donald "Slim" Haight started the business with just three people: Augie, Slim, and Augie's wife Gerry, who handled phones and books. As work grew, so did the team. Eventually, Augie's children, Nick and Dawn, joined the company, and later, his grandson became a plumber and came aboard. Today, Nick, Gerry, and Dawn continue the legacy. Many of their original customers from 1967 still call them for service.

Leadership

The Calfo family remains deeply involved in the daily operations. Nick, Dawn, and Gerry Calfo lead with the same values of honesty and community focus that Augie and Slim established. Their long-time technicians are treated like family, which is why many have stayed with the company for decades. This stability means consistent, reliable service for Wilmington DE residents.
