A failing sewer line is one of the more expensive plumbing repairs a homeowner faces, and the range is wide because no two lines are alike. Here's what determines the cost in Guadalupe County — and why we never quote one without looking inside the pipe first.
The camera comes first
Before anyone talks price, we run a sewer camera inspection (about $100–$450) down the line to see exactly what's wrong and where. Is it a single root intrusion at one joint, or widespread cracking and a collapse? That answer changes the job — and the cost — dramatically.
What drives the price
Length and depth
A short, shallow lateral is far cheaper to replace than a long, deep run. Depth especially matters — the deeper the pipe, the more excavation (or the stronger the case for trenchless).
Repair method
- Spot repair — fixing one damaged section is the least expensive option
- Trenchless (lining or pipe bursting) — repairs or replaces with minimal digging when the pipe qualifies
- Open-trench replacement — the traditional dig, used when the line has collapsed or trenchless isn't viable
What's on top of the line
If the sewer runs under a driveway, mature landscaping, or a patio, restoring those surfaces adds cost — which is exactly why trenchless is so valuable when it's an option.
Trenchless vs. digging
Trenchless methods cost more per foot than a simple dig but often come out ahead once you factor in restoring a driveway or protecting old trees. On properties in Seguin and across Guadalupe County, we weigh both and give you honest numbers for each.
Why Guadalupe County lines fail
Older neighborhoods carry clay and early cast-iron laterals that crack and let roots in. Mature live oaks and pecans are relentless about finding those gaps. And expansive clay soil movement stresses buried pipe over time. A camera tells us which of these you're dealing with.

Trenchless vs. Dig: The Real Cost Math
Trenchless lining or pipe bursting costs more per foot than an open trench, so on the plumbing line item alone, digging looks cheaper. But that comparison ignores what's on top of the pipe. When the line runs under a driveway, a mature live oak, a patio, or established landscaping, restoring those surfaces after an open trench can cost as much as the pipe work itself.
Factor in restoration and trenchless often wins on total cost — and always wins on disruption. That's the number that matters. We run the camera first, tell you whether your pipe is a trenchless candidate, and give you both figures side by side so you're deciding on the full cost, not just the part on the invoice.
Frequently Asked Questions
It depends on the material: modern PVC can last 50-plus years, older clay and cast iron often 40–60 before roots, corrosion, or settling catch up with them. Many Guadalupe County homes are now at the age where original clay laterals are failing, which a camera inspection confirms.
Not always — it depends on what's above the line and the pipe's condition. If the run is under open yard and easy to reach, an open trench can be cheaper. If it crosses a driveway, trees, or hardscape, trenchless usually costs less once restoration is counted. We give you both numbers.
Generally the homeowner owns the lateral from the house to the connection at the city main; the city owns the main itself. So a blockage or break in your yard is typically yours. We can confirm where responsibility shifts for your property during the camera inspection.
