A new water service line laid in a trench along a front yard sidewalk

A leak you can see is annoying. A leak you can’t see is worse, because it can run for weeks before you notice a jump in the water bill, a warm spot on the floor or a patch of grass that never dries out. By then, the water may have soaked into drywall, cabinets or the ground under your foundation.

The Right Guyz finds and fixes water leaks inside the house, under the slab and in the yard. We’ll track it down, show you where it is and give you a clear price to fix it.

Signs of a hidden leak

  • A water bill that’s higher than normal with no change in how you use water
  • The sound of running water when everything is off
  • A water meter that keeps moving with every faucet closed
  • Damp spots, stains or bubbling paint on walls and ceilings
  • Warped flooring, or a warm spot on a tile or slab floor
  • A soggy or unusually green area in the yard
  • Low water pressure throughout the house

Where leaks tend to hide

In many older San Antonio homes, the original galvanized steel water lines are still in the walls. Galvanized pipe rusts from the inside out, which narrows the pipe, drops the pressure and eventually opens pinhole leaks. Copper lines can leak too, especially where water pressure is high or where a pipe rubs against framing.

Yard leaks are common as well. The water service line between the meter and the house can crack as San Antonio’s clay soil swells and shrinks, or where tree roots push against it. One of our customers put it simply after a front yard leak, and you can read what they said in the reviews below.

If the leak turns out to be under the foundation, that’s a slab leak, and we can handle that too.

How we find it without tearing up the house

We start with the water meter to confirm there’s a leak and get a sense of how big it is. Then we isolate parts of the system to narrow down where it is. From there, listening equipment and pressure tests help us pinpoint the spot. The goal is to open one small area instead of cutting holes all over your walls or yard.

Fixing the cause, not just the drip

When we repair a leak, we also look at why it happened. If your water pressure is running high, a failing pressure reducing valve may be the real culprit, and a patch won’t last until that’s fixed. If a whole run of galvanized pipe is rusting through, we’ll show you and talk about repiping options, so you’re not calling us back for the next leak in a month.

How the job works

  1. 1

    Confirm there's a leak

    We check the water meter with everything turned off. If it's still moving, water is going somewhere.

  2. 2

    Narrow it down

    We isolate sections of the plumbing to figure out whether the leak is inside the house, under the slab or in the yard.

  3. 3

    Pinpoint the spot

    We use listening equipment and pressure testing to find the leak so we open up only what we have to.

  4. 4

    Repair and retest

    We fix the leak with the right materials, pressure test the line, and check the meter again to confirm it's stopped.

Leak Detection and Repair questions

How can I tell if I have a hidden water leak?

Turn off every faucet and water-using appliance, then look at your water meter. If the dial or the small leak indicator is still moving, you have a leak somewhere. A water bill that jumps for no reason is another common sign.

Is the leak my responsibility or the city's?

Generally, leaks on the house side of the water meter belong to the homeowner, and leaks on the street side belong to the water utility. If you're not sure where the leak is, we can help you find out.

Why do pipes leak in older San Antonio homes?

Galvanized steel supply lines rust from the inside and eventually pinhole or crack. Copper can wear thin, especially where water pressure is high. Shifting clay soil can also stress yard lines and pipes under slabs.

Can high water pressure cause leaks?

Yes. Pressure above about 80 psi strains pipes, fittings, faucets and water heater relief valves. If we find high pressure, we'll recommend checking or replacing the pressure reducing valve.
