Trenchless Sewer
Replacing a sewer line used to mean a trench the length of your yard. Trenchless methods replace the pipe along its existing path from two small access pits — which matters enormously when there is limestone six inches under the grass.
Camera first, always
No one should be quoting you a sewer replacement without having looked inside the pipe. An HD camera inspection shows what is actually wrong — roots at a joint, a bellied section holding water, scale narrowing the bore, a crushed length, or a separated connection — and where along the run it is. That determines whether you need a spot repair, a liner, or a full replacement, and those three cost very different amounts.
Why trenchless is worth more here than most places
Across far north Bexar, Helotes and Boerne, soils sit six to twenty inches above hard fractured limestone and can run 35% to 85% rock fragments by volume. Open-cut excavation through that is slow, loud and hard on driveways, mature trees and irrigation. Pulling a new line through the existing path avoids nearly all of it. On the clay side of the county — Schertz, Converse, east and south San Antonio — trenching is easier, so the calculation shifts and we will tell you when open-cut is genuinely the better option.
What tends to fail, and when
Below-ground cast iron waste pipe has a documented service life of 50 to 60 years. San Antonio has a large pre-1960 housing stock concentrated inside Loop 410, and cities like Leon Valley and Universal City were built out in the 1960s and 1970s — so a great many original lines in this area are now at or past that age. Add mature root systems, which SAWS names as a blockage cause on its own network, and recurring backups usually turn out to be a pipe problem rather than a clog problem.

Common questions
Trenchless Sewer — questions we get
How do I know if I need a sewer replacement or just a cleaning?
A camera inspection settles it. Repeated backups in the same place, gurgling drains, sewage smell in the yard, or patches of unusually green grass along the line all point at the pipe itself rather than a clog. If the camera shows sound pipe with a root intrusion at one joint, jetting and a spot repair will do. If it shows a bellied or fractured run, cleaning it just buys a few months.
Will you have to dig up my yard?
Trenchless replacement needs two access pits rather than a trench along the whole run, so the great majority of your yard, driveway and landscaping stays intact. We will show you where the pits need to go before any work starts.
How long does a trenchless replacement take?
Most residential replacements are a one-day job once the line is located and access is dug, though older properties with complex connections can run longer. We give you a flat-rate price after the camera inspection and before any work begins.
Is trenchless cheaper than digging?
It depends on the ground. In the Hill Country and far north Bexar, where limestone starts a few inches down, it usually is — the excavation saving outweighs the equipment cost. On the clay side of the county it can be closer, and we will say so rather than pushing the method that sounds more impressive.
