About Hernandez Plumbing Co.
Rafael Diaz and Alejandro Diaz run Hernandez Plumbing Co. as the third generation of a family business that started in 1972. Based in Doral, the company has grown into one of the larger plumbing operations in the area, with reviewers frequently describing the crew's approach as careful and communicative on every visit, something the company markets as "white glove service."

Several reviews mention a 90 day warranty applied to repair work, including one clogged line job that came in around $400 total.
Hernandez Plumbing Co. covers a broad territory that includes Doral, Miami Beach, Coral Gables, Hialeah, Kendall, Cutler Bay, Homestead, North Miami, and stretches into Fort Lauderdale, Hollywood, and Boca Raton. The company holds a 4.8 rating from 590 Google reviews, read September 18, 2026, making it one of the most reviewed plumbing companies on this list.
