“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 softeners?
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.
On a Williamson County well at the county median (16.5 grains per gallon), a family of four using about 300 gallons a day brings in roughly 4,950 grains of hardness every day. That daily load, not the size of the house, is what we size a softener to.

What Our Customers Say
Don't just take our word for it. Here's what homeowners in Georgetown and the surrounding areas have to say.
“Austin was Great! He arrived promptly. Very professional, thorough and importantly, his attention to detail. I strongly recommend Brandenburg and wouldn't think twice about using them in the future!”
“I purchased a toilet with bidet seat and the bidet seat was not staying in place. Plumbers came back several times to adjust, but it still was not staying in place. Lucas Brandenburg came by to see it first hand and discovered a design flaw. He immediately ordered a different brand to replace it and it was installed several days later. I truly appreciate the owner of the company taking my concerns seriously and coming out personally to diagnose the problem! The plumbers are all incredibly nice and knowledgeable and everyone was focused on fixing the issue. I am happy to endorse a hometown company with such great customer service @”
