Our story · Since 1983
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
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.

“One phone call was all that it took to find out newest plumbing partner for life. We had a brand new and previously installed water heater installed incorrectly and Mario came out the same day and repaired it in no time. Water heaters are tricky and you want someone who knows what they're doing. Leon plumbing is certified on all brands. From scheduling to the completion of work, I have been blown away by the quality and level of service I Ed offered .... Not common with plumbers. Also, I come to find out our previous installer had stripped the screws on our garbage disposal this causing it to make a loud rattling subs during use. If you're looking fine a plumber for life, call them, you will never call another plumber again, I promise.”

via Google“I needed a service for a Rinnai tankless water heater for a tenant in Eagle Rock. I called Leon plumbing and was surprised that they could have a tech out in about an hour. The tech did a complete service for $275, which seemed somewhat reasonable, and a needed valve replacement for another $275, which (though steep) was at least done quickly. I would recommend them for speed, good communications, and quality of the work.”
