Central Texas Sewer Repair You Can Count On
A failing sewer line is one of the more disruptive problems a home or business can face — and one of the easiest to misread as “just a clog.” CMM Plumbing has spent over 20 years diagnosing and repairing main sewer lines throughout Coupland, Austin, and the surrounding communities. As a family-owned company holding Master Plumbing License #46268, we approach every sewer job the same way: find the actual cause of the problem before recommending a fix, and use the repair method that matches the condition of the pipe — not the one that’s easiest to sell. If you’re dealing with repeated backups, slow drainage across multiple fixtures, or a yard that never quite dries out in one spot, our licensed plumbers can find out what’s really going on underground.
Signs You May Need Sewer Repair
Sewer line problems tend to build gradually, so the early warning signs are easy to dismiss. Watch for these symptoms, particularly if more than one shows up at the same time:
- Multiple drains backing up at once, especially the lowest fixtures in the house
- Gurgling sounds from toilets or drains when other fixtures are used
- Sewage odors in the yard, basement, or near cleanouts
- Soggy, unusually green, or sunken patches of lawn along the sewer line's path
- Slow drainage throughout the house that doesn't improve after standard drain cleaning
- Cracks in the foundation or slab near where the sewer line runs
Any one of these on its own might have another explanation. Seeing several together is a strong signal the main line itself needs attention, not just the fixture that’s acting up.
How We Diagnose Sewer Line Problems
Digging up a yard on a guess isn’t how we do business. Before we recommend any repair, we run a camera inspection to see exactly what’s happening inside the pipe. A waterproof camera is fed directly through the line, letting us pinpoint cracks, offset joints, root intrusion, bellies, and collapsed sections in real time — without any exploratory digging. That inspection tells us three things: where the damage is, how bad it is, and which repair method actually makes sense for it. It’s the same process we recommend when standard drain cleaning clears a blockage temporarily but the problem keeps coming back.
- Camera inspection to locate and assess the exact damage
- Root cause identification — tree roots, pipe age, ground shift, or collapse
- Clear explanation of what we found before any repair begins
- Straightforward pricing for the recommended repair method
Sewer Repair Options: Trenchless vs. Traditional
Once we know what’s wrong, we’ll walk you through the repair options that fit your specific line — not a one-size-fits-all recommendation.
- Trenchless pipe repair: Access points at each end of the damaged section allow us to reline or replace the pipe underground, which usually means far less digging and a faster return to a normal yard.
- Traditional excavation: When a line has fully collapsed, shifted badly out of alignment, or has damage trenchless methods can't reach, excavation and direct pipe replacement is the more reliable fix.
- Root intrusion removal: For root-related blockages that haven't yet caused structural damage, we can clear the roots and treat the line to slow regrowth.
- Aging clay and cast-iron line replacement: Older lines nearing the end of their service life are replaced with modern, more durable pipe material built to last.
Many older homes in Coupland and Central Texas still run on original clay or cast-iron sewer lines, which are more prone to cracking and root intrusion than modern pipe. If your sewer repair is part of a larger project — a remodel or a new construction build — we can coordinate the sewer work directly with the rest of the plumbing scope.

Sewer problems don’t improve on their own, and the longer a damaged line goes unaddressed, the more likely it is to affect your foundation, yard, or indoor plumbing.

Emergency service is available for active backups, and if you’ve spotted a leak alongside your drainage issue, our leak detection team can help track that down too.

Frequently Asked Questions About Sewer Repair
How do I know if my sewer line is the problem and not just one clogged drain?
A single slow drain is usually isolated to that fixture. When two or more drains back up together — especially the lowest fixtures in the house, like a tub or floor drain — or you notice sewage odors in the yard, that points to the main sewer line rather than an individual pipe. A camera inspection gives us a definite answer either way.
What causes sewer lines to fail in Central Texas?
The most common culprits we see are tree root intrusion at pipe joints, aging clay or cast-iron lines that have cracked or shifted with the region's expansive clay soil, and buildup from years of grease or debris. Older homes around Coupland and Austin are more likely to have original clay lines nearing the end of their service life.
What's the difference between trenchless repair and traditional sewer replacement?
Trenchless methods, like pipe bursting or lining, repair or replace the pipe through small access points instead of digging up the full length of the line, which usually means less disruption to your yard, driveway, or landscaping. Traditional excavation is still the right call when a line has collapsed, shifted out of alignment, or has damage that trenchless methods can't reach. We'll recommend the option that actually fits the condition of your pipe.
How long does a sewer repair or replacement take?
A localized trenchless repair can often be completed in a single day. Full replacement of a longer run, or a repair that requires excavation, may take longer depending on the length of pipe involved and site access. We'll walk you through a realistic timeline after the camera inspection.
