Frank Marrone & Sons Plumbing

We're Frank Marrone and Sons Plumbing Co., offering a variety of commercial and residential plumbing services throughout Southern California. Our projects include hospitals, tenant improvements, restaurants, custom homes, repiping, sewer and sump pump systems, state and federal projects, high-pressure gas systems, and much more. We've been family-owned and operated since 1973, when Frank Sr. started out of his home in Arcadia. In 1977, we leased a building in El Monte, and in 1978, we were incorporated as Frank Marrone and Sons Inc., later purchasing an industrial building on Lower Azusa Road in El Monte that remains our location today.
