Why have we been in business so long?

You could say we engineered it that way. When our founding fathers, Vernon Spalding and Frank DeDecker, first opened their doors in 1954, Spalding DeDecker promised to do business with integrity and a commitment to excellence. Two generations later, a handshake from Spalding DeDecker is still a firm promise you can count on.
