Our History

Back in 1947, Joseph Frederick started a small plumbing business on his front porch in Brack-Ex, on the edge of Elsmere.

In April of 2014, brothers Brian and Robbie Frederick celebrated the 68th anniversary of Joseph Frederick & Sons, which has grown and expanded from a “one-man, one-truck” business into a multimillion-dollar organization, providing residents of the Delaware Valley with plumbing, heating, cooling, and electrical services.
