Our “Know Before You Go” approach provides upfront pricing before any work begins, with no hidden fees or surprises.

Phase 1: Sewer Leak Detection in San Antonio

Every job starts with a systematic, non-invasive assessment to pinpoint the source of the problem. Using our Leak Detection Without Destruction™ principle, we locate the leak before any excavation begins.

  • Sewer Video Camera Inspection: We insert a camera directly into the line so our technicians can see a break or crack from the inside, with no digging required in most cases.
  • Acoustic Listening Devices and Pressure Testing: Used alongside camera inspection to help confirm the leak location, these tools can help us distinguish a sewer leak from a water line leak.
  • Clear Findings: We show you the camera footage, explain what we found, and provide a transparent, upfront estimate before any repair work begins.

Multiple slow drains or recurring backups can signal a problem farther along a shared sewer line rather than a clog at one fixture. Root intrusion, cracked pipe sections, joint separation, offsets, and pipe collapse can restrict flow or allow wastewater to escape into surrounding soil.

When a concern is beneath a slab, driveway, patio, or landscaped area, accurate locating helps identify the affected portion before sewer leak repair is considered. A camera-based diagnosis can also help show whether the issue appears localized or extends across a larger portion of the line.
