Schedule Slab Leak Repair in San Marcos, TX

What to Have Ready Before You Call

When dealing with a potential under-slab leak, having basic property information organized helps our dispatchers guide you accurately:

• Visible Symptoms: Note whether you feel warm floor areas, hear hissing sounds, see water pooling in grout, or notice buckled floorboards.
• Water Meter Observations: Check if your outdoor city water meter dial is actively spinning while all indoor taps are off.
• Recent Water Bills: Knowing if consumption spiked unexpectedly over the last billing cycle helps assess leak severity.
• Approximate Home Age: Knowing when your home was built helps us understand whether you likely have copper, polybutylene, PEX, or cast-iron lines.
• Main Shutoff Location: Identify where your main water cutoff valve is located (often near the front hose bibb or garage).

Safety & Mitigation Steps While Waiting for Service

To protect your structural foundation and prevent mold accumulation before the technician arrives:

1. If you hear active pressurized spraying or notice spreading dampness, turn the main water shutoff valve a quarter turn to cut off flow.
2. If the leak is confirmed hot (flooring is warm or your water heater is firing continuously), you can shut off the cold inlet valve on top of the water heater to preserve cold water service.
3. Photograph all wet flooring, baseboard swelling, and wall cracks for your records and potential insurance claims.
4. Wipe up standing surface water and set up household fans to circulate dry air across flooring.
