About Alonso Plumbing Services

Alonso Plumbing Services is a licensed and insured plumbing company serving Los Angeles and surrounding areas. Founded on the principle that every home deserves reliable, code-compliant plumbing, we specialize in emergency dispatch, leak detection, water heater installation, repiping, and drain repair for residential and light commercial properties. Our crews have seen it all — from century-old galvanized lines hiding behind lath-and-plaster walls to brand-new construction where the inspector flagged a improperly sloped drain on the final walk-through.

Our team of certified plumbers brings decades of combined field experience to every job, from a simple faucet swap to a full copper repipe. We operate 24 hours a day, 7 days a week, because plumbing emergencies don't wait for business hours. When a pipe bursts at 2 AM or a water heater fails on a holiday, our dispatch team routes the nearest available technician to your door with a fully stocked truck — no waiting for parts, no second visit, no surprises on the invoice.

We believe in transparent pricing, honest diagnostics, and workmanship that lasts. Every repair is backed by a satisfaction guarantee, and we use only premium-grade materials — copper, brass, and brand-name fixtures. Se Habla Español. We proudly serve the diverse communities of East Los Angeles, Montebello, Monterey Park, and beyond, treating every home as if it were our own.
