Your neighborhood plumbers since 1983
Leon Plumbing is a family-owned company founded in 1983 in the Sunland/Crescenta Valley area. For more than four decades, we’ve helped neighbors keep their homes comfortable, their hot water reliable and their plumbing working as it should. We’re based in Sunland and serve Sunland, Tujunga, La Crescenta, Montrose, La Cañada Flintridge, Glendale, Burbank, Pasadena and Altadena.
Tankless water heaters are a specialty of ours. As an authorized Rinnai dealer, we help you choose a system that fits your household, install it properly and keep it running with repairs and regular maintenance. Whether your shower turns cold or you’re ready to replace an aging tank, we’ll explain your options in plain language so you can make a confident decision.
We also handle everyday plumbing needs, from stubborn drains and hidden leaks to whole-home repiping. Our CSLB C-36 license is #474827. You can expect honest diagnostics, upfront pricing and care for your home. Call our local team to discuss your project or arrange a visit, with same/next-day service when available.

Helping Altadena & Pacific Palisades rebuild
Leon Plumbing is actively helping families and businesses affected by the Altadena and Pacific Palisades fires get their plumbing back — safely and affordably.
Post-fire plumbing inspections. Heat, ash and firefighting water pressure can damage pipes, water heaters, gas lines and backflow devices. We inspect the full system and document findings for your insurance claim.
Repipes, gas lines & water heaters. From smoke- and heat-damaged repiping to gas line safety checks and water heater replacement, our licensed crews get fire-affected homes back to normal.
Priority scheduling for fire victims. If your home or business was impacted by the Altadena or Pacific Palisades fire, call (818) 326-0780 and mention the fire — you'll go to the front of our schedule.

Kevork Ashjian
via Google“⭐⭐⭐⭐⭐ Sevag is excellent! He is professional, reliable, and knowledgeable, and takes pride in doing quality work. He explains everything clearly, is dependable, and makes sure the job is done right. It’s hard to find someone you can trust, and Sevag definitely delivers! I highly recommend him to anyone looking for outstanding plumbing services.”
Joseph Khankhanian
via Google“Highly highly recommend Leon Plumbing! I recently moved into a new unit and needed the gas valve turned on before my laundry machines could be installed. Sevag came out and took care of everything so quickly and efficiently. I was really impressed with how responsive, professional, and knowledgeable he was. He made the whole process so easy and stress-free. It’s hard to find reliable service like this these days. Will definitely be using Leon Plumbing again!”
Anna Adamian
via Google“Our tankless water heater stopped working. We spent a week taking cold showers before we called Leon Plumbing. Jacob, (who works for Leon Plumbing) showed up 15 minutes after we called. We assumed we would need a brand new water heater (at a cost over $4,000) but Jacob disassembled the unit, fixed the problems and within 30 minutes we had hot water! We couldn’t be happier with the service he provided. We will use Leon Plumbing for all Our future plumbing issues.”
