“Brandenburg Plumbing provided excellent service diagnosing and repairing a water leak for one of my trusted seller clients. The issue was identified quickly, clearly explained, and resolved properly by replacing the leaking valve. Efficient, professional, and done right the first time. Lucas, the owner and master plumber, sets a high standard. His expertise, professionalism, and leadership are evident throughout the process. He takes a methodical, no-nonsense approach and prioritizes quality workmanship. The entire team was professional and respectful, and communication was smooth from start to finish. An honorable mention to Nick McBride, an outstanding journeyman plumber whose skill, attention to detail, and professionalism stood out. For context, I am Chris Cabiya, Founder and Principal Realtor® at Cabiya Realty Group and a local real estate investor serving the Highland Lakes area, including Marble Falls, Horseshoe Bay, and Granite Shoals. I hold service providers to very high standards on behalf of my clients. Brandenburg Plumbing met those standards without hesitation. Highly recommended.”

What should Horseshoe Bay homeowners know about water heaters?
Horseshoe Bay city water comes from Lake LBJ and averages 175 mg/L of hardness, about 10.2 grains per gallon (City of Horseshoe Bay 2019 water quality report). The U.S. Geological Survey classes that as hard.
Private wells in Llano County run harder: the median sampled well tests 328 mg/L, about 19.2 grains per gallon, and 93% of sampled wells test very hard. About 9% of Llano County residents get their water from a private well.
Noritz, Navien and Rheem all exclude scale damage on tankless water heaters above 200 mg/L (about 11.7 grains per gallon). Horseshoe Bay city water averages 175 mg/L, 25 mg/L under that limit, so tankless works on city water with yearly descaling. On a private well, which usually tests well over the limit, plan on a softener.

“Our Air conditioner stopped working the day before a huge party on the hottest day. Josh came out first thing in the morning and installed the part. We joined their HVAC plumbing maintenance and they came back and maintenance the HVAC and then the plumbing guy came and flushed the water heater and did maintenance as well as check flow of house water. The are great people friendly polite and fairly priced. There is great follow up and quick response to questions. Best customer service I have encountered in a long time. It is a forgotten art.”
