- Shut off the water. Close the valve at your meter box, then call the Public Works warehouse. The city routes water line repairs, leaks, and sewer backups there; billing questions go to City Hall.
- Make it safe and document it. Cut power to wet rooms from a dry spot, photograph the damage, then report the claim.
- Start drying within 24 to 48 hours. About 52% of Mexia's homes were built before 1980, and 21% before 1960. Old cast iron drains and galvanized lines fail at joints, so ask for readings in nearby walls and floors.
