“Leon Plumbing’s team were great to work with! I had a minor leak coming from my kitchen sink and the team came out immediately and fixed the problem. Communication was easy and straightforward. Thank you to our tech Mario and Datevig and Sevan for a smooth experience!”
Erika Liu Wong
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.”
