Elgin has managed to hold onto its small-town character even as growth pushes east from Austin. That mix shows up in the plumbing work we do here—older homes near downtown sit not far from newer residential streets, and plenty of properties on the outskirts still rely on wells and septic systems rather than city utilities. At CMM Plumbing, being based just a few miles away in Coupland means we already know how these different property types tend to age and what to look for before a small issue turns into a bigger one.

• In Historic Downtown Elgin, many homes were built decades ago, and quite a few reflect the town's long brick-making tradition. Older plumbing systems in this part of town often mean aging galvanized pipe, worn water heaters, and fixtures that have simply reached the end of their service life. We're regularly called out for leak detection, repiping, and water heater replacement in these older properties.
• In New Residential Development, Elgin has grown steadily as families look for affordable homes within easy reach of Austin, and new subdivisions continue to fill in around town. Even brand-new construction needs plumbing installed correctly the first time—proper fixture set, correct pressure, and clean, code-compliant work that won't cause problems down the road.
• In Rural & Outlying Properties, it's common to find homes on private wells and septic systems rather than city water and sewer, which is typical for much of Bastrop County outside the city core. We understand how to work with well pressure systems and septic-safe plumbing practices, so these properties get the same careful attention as anywhere else.
• Being Close to Coupland works in Elgin's favor—our shop is just down the road, which means shorter drive times, faster response for emergencies, and a crew that already knows the area rather than one commuting in from across town.

No matter where you are in Elgin—downtown, a new subdivision, or a property out toward the county line—our goal is the same: show up on time, communicate clearly, and fix the problem the right way the first time.

• 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 an older home near downtown or a new water heater install in a subdivision on the edge of town. 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 Elgin or Bastrop 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 Elgin holds a special place for us—it's one of the closest towns to our own home base in Coupland, and we've gotten to know it well over the years. Elgin's identity as the “Sausage Capital of Texas” is tied to a sausage-making tradition that goes back generations, anchored by barbecue institutions that have called the town home for longer than most Central Texas businesses have existed. That same history runs through the town's brick-making legacy, too—Elgin's clay-rich soil helped build a brickmaking industry that shaped a lot of the historic architecture you still see around downtown today.

Beyond the history, what we appreciate most is Elgin's small-town feel. It's a community where people still know their neighbors, local businesses matter, and folks tend to appreciate a plumber who shows up, does the job right, and treats them fairly. Being just down the road in Coupland means we're not driving in from across a big city—we're neighbors, and we take that relationship seriously. As Elgin continues to grow with new residential development, we're glad to be part of a town that's adding new families and new homes without losing the character that makes it Elgin.
