- Our Story
A Plumber You Can Actually Trust
Knockout Plumbing Services, LLC was founded by Jacob Sconci, a licensed Responsible Master Plumber (RMP #45640) with more than 17 years of experience in the plumbing trade. Jacob built his career working on everything from residential service calls to large commercial construction projects, and he started Knockout Plumbing Services to bring that expertise directly to the Highland Lakes community he calls home.
The name says it all: when you have a plumbing problem, we knock it out. No runaround, no upselling, no leaving you hanging. Jacob’s approach is straightforward — show up, diagnose the problem accurately, fix it right, and charge a fair price. That’s it.
Based in Kingsland on Lake LBJ, Knockout Plumbing Services serves all communities in the Highland Lakes region of Central Texas, from Marble Falls and Horseshoe Bay to Burnet, Llano, Granite Shoals, and beyond. We know this area, we know its water, and we know its plumbing.
