About Marino & Son Plumbing & Heating
Marino & Son Plumbing & Heating has anchored itself in Baton Rouge since 1925, making it one of the oldest family-owned plumbing operations in Louisiana. Now led by Stephanie Marino-Dauzat and her cousin Donnie Marino (LMP# 3490), the company traces its roots to Sam F. Marino and has maintained continuous operations for nearly a century. The company holds a 2.9-star rating from 7 customer reviews and operates Monday through Friday from 7:30 AM to 4 PM, serving Baton Rouge and surrounding neighborhoods including Mid City, where the business maintains its physical presence.
What distinguishes Marino & Son is their deep involvement in commercial and institutional construction projects throughout Baton Rouge. Their portfolio includes plumbing work for the original Planetarium, LA Correctional Institute for Women, multiple school campuses (Tara, Port Allen, Episcopal High Schools, Melrose, LaSalle, and Woodlawn Elementaries), and religious facilities like Most Blessed Sacrament Catholic Church. This commercial foundation suggests experience with large-scale installations, though residential service calls also form part of their business mix.
Customer experiences at Marino & Son reveal mixed results. Recent negative reviews cite damaged walls during water heater replacement, rude phone interactions, and no-show appointments without explanation. However, satisfied customers praise their reliability and workmanship, with reviewers noting they would not call anyone else for plumbing needs. The company has maintained operations through four generations, suggesting community trust despite inconsistent service delivery.
