Liberty Hill has changed a lot over the past couple of decades, and that change shows up in the plumbing work we do here. Not long ago, this was a small ranching and farming community sitting along the South San Gabriel River, and a good number of homes still reflect that history—larger rural lots with private wells, septic systems, and plumbing that's aged right along with the property. At the same time, Liberty Hill has become one of the fastest-growing areas in Central Texas, with new subdivisions and master-planned communities such as Santa Rita Ranch bringing thousands of new homes tied into municipal water and sewer service.

That mix means the plumbing challenges we see vary a lot from one property to the next. On the older, larger-acreage side of town, we're often called out for well pump and pressure tank troubleshooting, septic-related drain issues, and updating original piping that was never designed for today's water usage. In the newer developments, the calls tend to be different—builder-grade fixtures that need attention, warranty repairs, tankless water heater installs, and the kind of fine-tuning that comes with a house that's only been lived in for a year or two. We've worked on both sides of that divide long enough to know what to look for either way, and we treat a well-and-septic property out past the edge of town with the same care and attention as a brand-new home in a subdivision off Highway 29.

• Plumbing Maintenance: Plumbing issues rarely happen out of nowhere — they build up over time. Our plumbing maintenance helps catch small problems early, like slow drains, worn valves, pressure issues, and minor leaks, before they turn into expensive repairs. It's a great option for homeowners, landlords, and businesses who want fewer surprises.
• Drain Cleaning: Slow drains and recurring clogs are usually caused by grease, soap buildup, hard water scaling, or debris trapped in the line. We clear kitchen, bathroom, and main sewer drains thoroughly so the problem doesn't come right back. Most drain issues can be resolved in a single visit.
• Sewer Repair and Replacement: If multiple drains are backing up or you're dealing with repeated clogs, the issue may be in the main sewer line. In Austin, tree roots and aging sewer lines are common causes of sewer damage. We diagnose the problem, explain repair options clearly, and restore proper flow as quickly as possible.
• Leak Detection and Repair: Leaks aren't always obvious — many show up as higher water bills, damp spots, low water pressure, or the sound of running water when nothing is on. We locate the source of the leak and repair it properly to prevent water damage and mold. Whether it's under a sink or behind a wall, we focus on accurate diagnosis first.
• Repiping Services: Older plumbing systems can lead to frequent leaks, low pressure, discolored water, or repeated pipe repairs. Repiping replaces failing lines with new, reliable piping designed to last. We walk you through the best approach for your home and complete the work with minimal disruption.
• Sump Pump Services: A sump pump is your first line of defense against flooding when heavy rain hits. We install, maintain, and repair sump pumps to help protect basements, crawl spaces, and low-lying areas from water intrusion. If your pump fails, we can diagnose the issue quickly and restore protection.
• Water Heater Repair and Replacement: Hot water problems are often caused by sediment buildup, worn components, or hard water damage — especially in Austin. We repair and replace both tank and tankless water heaters, and we help you choose the right unit for your household's needs. Many repairs can be completed the same day.
• Fixture Repair and Installation: Dripping faucets, loose fixtures, and leaking showerheads waste water and can drive up your bill over time. We repair and install sinks, faucets, shower fixtures, and more — making sure everything is sealed correctly and working the way it should. It's one of the fastest ways to improve comfort and prevent damage.
• Backflow Testing and Prevention: Backflow issues can allow contaminated water to flow into the clean water supply, which is why testing and prevention are so important. We provide backflow testing, repairs, and prevention solutions for homes and commercial properties. Our goal is to keep your water supply safe and code-compliant.
• Hydro Jetting: Some clogs are too severe for standard drain clearing — especially when grease, roots, or heavy buildup are involved. Hydro jetting uses high-pressure water to fully clean the inside of sewer lines and restore proper flow. It's one of the most effective solutions for recurring drain and sewer problems.
• Water Treatment and Filtration: Austin's water can be tough on plumbing, appliances, and fixtures due to mineral content and hard water buildup. We install and maintain water filtration and treatment systems to improve water quality and reduce scaling. Cleaner water can also help extend the life of your plumbing system.
• Toilet Repair and Installation: A running toilet, weak flush, or frequent clogs usually points to worn internal parts or a deeper drain issue. We repair common toilet problems and install new toilets with proper sealing and leak prevention. In many cases, toilet repairs can be handled in one visit.

1. Discovery & Consultation

We begin with a detailed phone or on-site consultation to understand your needs and goals—whether it's a slow drain in a longtime rural home or setting up plumbing for a new outdoor kitchen in one of Liberty Hill's newer subdivisions. We take the time to listen, ask the right questions, and assess your current plumbing situation so we can recommend the best solution.

2. Design & Proposal

Once we've identified the issue or project scope, we prepare a transparent, itemized estimate with a clear timeline. You'll know exactly what to expect before any work begins—no surprises, just honest communication and professional planning.

3. Permitting & Preparation

For larger jobs like water heater replacements, remodel plumbing, or gas line installation, we handle all necessary permits with the City of Liberty Hill or Williamson County. We also take steps to prepare your space—laying protective coverings and ensuring the work area is clean and safe.

4. Professional Execution

Our licensed, certified plumbers carry out the work with precision and care. We arrive on time, work efficiently, respect your space, and follow all local codes and best practices to deliver lasting results you can trust.

5. Quality Check & Walkthrough

When the job is complete, we perform a thorough inspection to make sure everything meets our quality standards. We then walk you through the finished work, answer your questions, and share helpful tips for maintenance or care.

6. Post-Project Support

Our relationship doesn't end when the tools are packed up. If you have questions, need adjustments, or want to schedule future maintenance, our team is just a call away. We're here to support you long after the job is done.

CMM Plumbing LLC has proudly served Central Texas since 2012, and Liberty Hill is one of the communities we've watched grow the most. It wasn't so long ago that this was a quiet ranching town along the South San Gabriel River, and that history is still visible in the older homesteads and wide-open properties on the edge of town. Today, Liberty Hill is one of the fastest-growing communities in Central Texas, with new neighborhoods stretching out along Highway 29 toward Georgetown and Leander, all set against the rolling hills and limestone terrain that mark the beginning of the Texas Hill Country.

Some of what makes Liberty Hill special to us includes:

• The South San Gabriel River: Winding along the edge of town, the river has long shaped where and how Liberty Hill was settled, and it still gives the area a quiet, small-town feel even as growth continues around it.
• Hill Country Scenery:Liberty Hill sits right where the flatter farmland of Central Texas starts to give way to the rolling hills and limestone outcrops of the Hill Country—a view that makes even a routine service call feel like a drive through the countryside.
• A Small Town Growing Fast: Liberty Hill has gone from a sleepy ranching community to one of the fastest-growing areas in Central Texas, with new subdivisions and a growing school district reflecting just how many families are choosing to put down roots here.
• Deep Ranching & Farming Roots:The town's agricultural history is still part of its identity, and many longtime residents still work larger rural properties that have been in the family for generations.
• A Close-Knit Community Spirit: Even with all the new growth, Liberty Hill has held onto a genuine small-town feel, where neighbors still know each other and local businesses are supported by the community around them.

Liberty Hill's people make this work meaningful. From families who've worked the same land for generations to new homeowners just settling into their first house here, we're honored to be trusted again and again. We're proud to play a small role in helping Liberty Hill grow while it holds onto the small-town character that makes it such a special place to live.

• Certified Expertise: Our team is trained and certified in advanced systems like Navien and Rinnai tankless water heaters, along with gas line and water line installations — so your work is completed safely and correctly.
• Permits & Code Compliance: When a plumbing project requires it, we can help handle permits and ensure work is completed to meet City of Liberty Hill or Williamson County requirements — especially for replacements, upgrades, and remodel plumbing.
