About Leon Plumbing
A family-owned plumbing company from Sunland, California with 40+ years of honest diagnostics, upfront pricing and work done right the first time.
The Leon story
Serving Southern California since 1983
Leon Plumbing started in 1983 with a simple idea: treat every home like our own. More than four decades later we're still family owned and still based in the Foothills, serving Greater Los Angeles, the San Fernando Valley, the Westside and Santa Clarita.
Today the business is led by Sevag Leon, who keeps the same standard on every job, explain the problem clearly, quote the price before work begins, and leave the system cleaner and safer than we found it.
From tankless water heater installs and whole-home repipes to drain, sewer and leak work, we're the team neighbors call back for decades.

“When I called on a Friday at 2 PM for a water regulator failure, a technician arrived within an hour and came fully prepared. Seth, Harry, and Omar are a fantastic team.”
“Authorized Rinnai dealer who does excellent and neat work. Sev came out ASAP after Eaton Fire ash blocked our tankless venturi — and fixed it at no charge.”
“We had a broken valve with a leak. They came that afternoon and replaced the bad parts the same day.”
“Efficient, professional, and went above and beyond. Quick responses, real knowledge and experience. Highly recommend.”
