Meet the Team
Two generations leading a Miami plumbing legacy built on craftsmanship, honesty, and standing behind every job.
Owner
Rafael Diaz
Licensed plumber · 40+ years in the trade
Rafael grew the family business alongside founder Pedro Hernandez — helping train others for state licensing, then leading large-scale plumbing work across South Florida as Miami developed. His background spans high-rise and new construction, major residential and commercial projects, and deep expertise in leak detection, cast iron replacement, and repiping — often using non-invasive approaches that save homeowners unnecessary demolition. He has also served as an expert witness in plumbing-related claims.

President
Alejandro Diaz
Licensed 3rd generation plumber
Alejandro continues a Miami tradition of quality work, integrity, and honest service. As third-generation leadership, he carries forward the same values of craftsmanship and standing behind every job — treating every home like it's his own.
Meet Alejandro →A Local, Family Business You Can Trust
Pedro Hernandez founded the company in 1972 as Miami grew block by block. Today Owner Rafael Diaz and President Alejandro Diaz — second and third generation — still run a local service company, not a call-center franchise. We focus on residential and commercial service calls, cast iron replacement, kitchen and bathroom remodels, and 24/7 emergencies from slab leaks to sewage backups.
We carry Florida plumbing contractor licensing and insurance. Lead plumbers hold the required certifications and train on the tools that matter here: acoustic leak detection, sewer camera, hydro jetting, and cast-iron replacement under South Florida slabs. Larger projects get a dedicated account lead so scope, permits, and finish work stay coordinated.
After more than 50 years, the standard is still simple: diagnose honestly, quote before we work, and leave the problem solved with a 100% satisfaction guarantee. Service area covers Miami-Dade and Broward — from Brickell high-rises to Hialeah bungalows and Coral Gables historic homes.
Full-Service Plumbing
Residential and commercial service calls, cast iron replacement, kitchen and bathroom remodels, and 24/7 emergency response.
Licensed & Insured
Every lead plumber holds required certifications and carries the on-the-job training to handle jobs of any scale.
“We treat every home like it's our own. That's how it's always been, and that's how it'll stay.”
— The Hernandez Family
Dedicated Project Support
For larger projects, we assign a specialized account representative to make sure everything meets your expectations.
