Leak Detection & Repair in San Antonio, TX
A higher water bill, a damp spot on the wall, or the sound of running water when nothing is on? Alamo City Waterworks finds hidden leaks before they turn into real damage.
The Real Problem
The Leak You Can't See Is the One That Costs the Most
A leak inside a wall, under a slab, or behind a fixture does not announce itself the way a burst pipe does. By the time you notice water damage or a spiking bill, the leak has often been running for a while.
Guessing at the source and opening up walls to look for it wastes time and money. Finding the actual leak first saves both.
How We Track Down a Leak
We use leak detection methods that let us find the source without tearing your home apart guessing. Once we know exactly where it is, we give you the repair options and the cost before doing anything.

Leak Detection Questions
What are the signs of a hidden water leak?
A higher-than-normal water bill, a damp or warm spot on the floor or wall, the sound of running water when everything is off, or a musty smell are all common signs.
Why is my water bill suddenly higher?
If your usage hasn't changed but your bill has gone up, a hidden leak is one of the most common causes. We can help you find out if that's what's happening.
Can a leak cause mold or structural damage?
Yes. A leak that runs long enough can lead to mold growth, damaged drywall, warped flooring, and in serious cases, damage to the structure itself. Catching it early keeps the repair smaller.
Do you check for slab leaks?
Yes. Slab leaks are one of the harder types to spot on your own, and we use leak detection methods built for finding exactly that kind of issue.
How do you find a leak without tearing out walls?
We use listening equipment and other non-invasive detection methods to narrow down the source before opening anything up, so any repair work is targeted instead of exploratory.
Do you handle leak detection for commercial properties?
Yes, we find and repair leaks for San Antonio businesses as well as homes.
