“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.”

Georgetown, TX
What should Georgetown homeowners know about water filtration?
Georgetown’s water quality report does not publish a hardness figure. Its Lake Georgetown water is treated by the City of Round Rock.
Private wells in Williamson County run harder: the median sampled well tests 282 mg/L, about 16.5 grains per gallon, and 78% of sampled wells test very hard.
A utility treats and tests city water, but nobody tests a private well for you. We test the water first, then recommend filtration for what the test actually shows.
