CERTIFICATIONS AND AFFILIATIONS

When Should You Call a Leak Detection & Repair Company in San Antonio, TX?

1. When You Notice Rising Water Bills for No Clear Reason

If your monthly water bill suddenly climbs even though your usage has not changed, a hidden leak is often the cause. Finding it early can save you from higher costs and major repairs.

2. When You See Wet Spots on Walls, Floors, or Ceilings

Moisture appearing in random areas is a strong sign that water is escaping behind the surface. These leaks spread quickly and can damage drywall, flooring, and framing if ignored.

3. When You Hear Dripping or Running Water With No Fixtures On

Unusual sounds inside the walls often point to a hidden leak. This is common in older San Antonio homes where pipes can shift, loosen, or wear down over time.

4. When Your Water Pressure Drops Suddenly

A sudden drop in pressure usually means water is escaping somewhere in the system. This early warning sign gives you a chance to fix the leak before it becomes a larger problem.

5. When You Notice Musty Smells or Signs of Mold

Moisture trapped behind walls or flooring often leads to musty odors and mold growth. If you cannot find the source, a leak detection service can track it down safely.

6. When Your Floors Feel Warm, Soft, or Uneven

Warm or soft spots in flooring often suggest a leak under the slab or beneath the surface. These leaks can spread quickly and should be inspected right away to prevent major damage.

What’s our process like when finding a leak & repairing it?

We begin by inspecting your plumbing system to find the exact location of the leak. Instead of guessing, we use proper leak detection tools to check for hidden moisture, damaged pipes, pressure drops, and any signs of water escaping behind walls or under flooring. This lets us identify the real source of the issue and choose the safest, most effective way to stop the leak and protect your home.

 

Once we locate the problem, we repair the damaged section and make sure the surrounding plumbing is stable. After the repair is complete, we restore water flow, test the system for pressure and leaks, and confirm that everything is working correctly. Before we finish, we check for any signs of leftover moisture and make sure your home is fully protected from future water damage.

Specific Work Practices Include:
  • We begin by inspecting your plumbing system to pinpoint the exact source of the leak. Whether it is hidden behind a wall, under the floor, or coming from a damaged section of pipe, our goal is to find the real cause instead of guessing. Using accurate leak detection tools, we map out what is happening and create a clear plan to stop the water safely without adding more stress to your home.

     

  • After we identify the problem, we repair the damaged area and make sure the surrounding plumbing is stable. Once the fix is complete, we restore water flow, test the pressure, and check for any remaining signs of moisture to confirm the leak is fully resolved. Before we leave, we make sure everything is running smoothly so the issue does not return.
