About Kirk Garrett, Master Plumber & Owner
KMG Plumbing is owned and run by Kirk Garrett — a Louisiana-licensed master plumber (License #5848), Master Natural Gas Fitter, and approved Backflow Tester listed with the Sewerage & Water Board of New Orleans. He built the company on a simple goal: be the plumber he'd want working in his own home. That means showing up when we say we will, treating your property with respect, and giving you honest options instead of aggressive sales pitches. And it means going where most plumbers won't — crawlspaces, attics, under-slab, you name it.

"Woke up to a leaking water heater flooding the garage. KMG was here within 45 minutes, stopped the leak, and had a new unit installed by that afternoon. Life savers."
