Emergency Plumbing Repair & Replacement in San Marcos, Texas

When a plumbing disaster hits, every minute matters. A slab leak in Oak Heights, a burst pipe in Southwest Hills, or a sewer backup in Two Rivers East can quickly turn into major damage if it’s not handled fast. That’s why Christianson Air Conditioning and Plumbing offers 24-hour plumber availability for genuine emergencies in San Marcos, Texas, and throughout Hays County.

Typical emergencies our San Marcos emergency plumber team handles:

  • Burst or cracked pipes: Sudden flooding from walls, ceilings, or under slabs.
  • Severe leaks: Rapidly dripping or spraying lines at water heaters, sinks, or toilets.
  • Sewer backups: Wastewater coming up through tubs, showers, or floor drains.
  • Major clogged drain problems: A completely blocked drain or main line with overflow.

When you call for emergency plumbing repair:

  • A dispatcher connects you with our 24-hour plumber team for emergencies.
  • We talk you through shutting off the water to limit damage.
  • A trusted technician arrives with the tools to stabilize and repair the problem.

If your plumbing system is older or has failed repeatedly, we may recommend emergency plumbing replacement instead of another patch. Our repiping services and plumbing replacement options in the Greater San Antonio corridor are designed to fix the underlying cause—not just the latest leak.
