Slab Leak Repair & Leak Detection

A water bill that keeps climbing with no visible leak is one of the most common calls we get. Most San Antonio-area homes sit on concrete slab foundations, and the clay soils here shrink and swell with drought and rain — that movement stresses the water and drain lines running under the slab until something gives.

Griffin & Son's Plumbing finds the leak first, then explains your options in plain language before any work starts. Depending on where the leak is and the condition of the rest of the piping, the right fix may be a spot repair through the slab, a reroute of the line, or a repipe of the affected section.

Signs you may have a slab or hidden leak

• Your water bill jumped but your usage didn't change
• The water meter keeps spinning with every fixture turned off
• Warm or damp spots on the floor, or the sound of running water
• New cracks in flooring or walls, or mildew under carpet
• Low water pressure that came on suddenly

How we handle it

• Locate the leak before opening anything up
• Explain repair vs. reroute vs. repipe — and what each one costs
• Make the repair to code under a Texas Master Plumber license
• Test the system afterward so you know it is fixed
