Service Details

When you suspect a leak under your yard, driveway, or slab, you need answers fast. At Plunger Pros, we provide underground leak detection for homeowners in New Braunfels, San Antonio, and surrounding areas. We are licensed and insured, and we bring a hands-on, honest approach to every job. Our goal is simple: find the source of the problem with as little guesswork and disruption as possible. That is how we deliver Plumbing Done The Proper Way.

Underground leaks can waste a lot of water and cause expensive damage if they are not found early. In many homes, these leaks happen on water lines, sewer lines, or pipes running below concrete slabs and landscaping. Because the piping is hidden, the warning signs are often easy to miss at first. You may notice a sudden spike in your water bill, wet spots in the yard, muddy areas that never dry out, low water pressure, the sound of running water when no fixtures are on, warm spots on the floor, or cracks in flooring and foundation areas. If you have seen any of these signs, it is a good time to call us for professional leak detection.

What underground leak detection includes

Our underground leak detection service is designed to locate hidden plumbing leaks as accurately as possible before unnecessary digging begins. We inspect the situation, listen to your concerns, and use our plumbing experience to narrow down where the issue is likely coming from. Every property is different, so we adjust our process based on the age of the home, pipe material, layout of the system, accessibility, and the symptoms you are seeing.

In many cases, leak detection may include a detailed evaluation of:

  • Main water service lines
  • Underground water pipes in the yard
  • Slab leak symptoms and below-slab water lines
  • Sewer and drain line concerns
  • Pressure loss in plumbing systems
  • Visible signs of soil saturation or foundation moisture
  • Meter activity that suggests a hidden leak

Our focus is to help confirm whether a leak exists, identify the most likely location, and recommend the next best step for repair. That can save you time, stress, and unnecessary property damage.

Common causes of underground leaks

Underground plumbing lines can fail for several reasons. In our experience, some of the most common causes include aging pipes, corrosion, shifting soil, poor installation, heavy ground movement, tree root intrusion, and normal wear over time. In the San Antonio area, changing soil conditions can place extra stress on buried lines and slab plumbing. Even a small crack or pinhole leak can turn into a major issue if it keeps leaking day after day.

Some leaks start suddenly. Others develop slowly and only become obvious after your monthly water bill climbs or your yard stays soaked. That is why early leak detection is so important. The sooner we find the issue, the more options you usually have for an efficient repair.

Why professional leak detection matters

Finding an underground leak is not just about seeing water on the ground. Hidden plumbing problems can mimic other issues, and guessing can lead to wasted time, unnecessary excavation, and bigger repair bills. We take a professional approach because accuracy matters. If a pipe is leaking under concrete, near a foundation, or deep in the yard, knowing the likely location before breaking ground can make the repair process far smoother.

Professional underground leak detection can help with:

  • Reducing unnecessary digging and damage to landscaping
  • Protecting your slab and foundation from ongoing water exposure
  • Helping lower water waste and high utility bills
  • Finding hidden leaks before they get worse
  • Creating a clear repair plan based on the problem
  • Giving you peace of mind about what is really going on

We believe customers deserve clear communication, honest recommendations, and practical solutions. We will explain what we find in simple terms and help you understand your options.

Signs you may need underground leak detection

If you are not sure whether you need this service, here are some of the most common red flags we see:

  • Unexpected increase in your water bill
  • Low water pressure throughout the home
  • Water meter keeps moving when no water is being used
  • Wet, soft, or unusually green patches in the yard
  • Mildew, damp smells, or indoor moisture with no clear cause
  • Cracks in flooring or foundation areas
  • Hot spots on the floor that may point to a hot water slab leak
  • The sound of water running behind walls or under the home

If any of these sound familiar, do not wait too long. A hidden leak can do real damage over time, especially when it affects structural areas or causes ongoing soil movement around the home.

FAQs

Underground Leak Detection FAQs

If you think you may have a hidden water leak under your slab or in an underground water line, these are the questions we hear most often. At Plunger Pros, we believe in Plumbing Done The Proper Way, and that means giving you clear answers before we start any work.

  • How do I know if I have an underground water leak?

    Common signs include a sudden spike in your water bill, wet spots in the yard, low water pressure, the sound of running water when everything is off, or warm spots on the floor if a hot water line is leaking under the slab. If you notice any of these issues, it is smart to have it checked quickly. Underground leaks usually do not get better on their own, and waiting can lead to water damage, foundation concerns, and higher utility costs.

  • Can you find the leak without digging up my yard or floor right away?

    In many cases, yes. We use professional leak detection methods to pinpoint the problem as accurately as possible before recommending any digging. Our goal is to reduce unnecessary damage to your yard, driveway, or slab and help you avoid guesswork. Once we locate the leak, we will explain what we found and walk you through the best repair options.

  • Is an underground leak an emergency?

    It can be. A small leak may seem minor at first, but underground plumbing leaks can waste a lot of water and cause serious property damage over time. If you have no water, very low pressure, standing water, soggy ground, or signs of a slab leak inside the home, do not wait. Call Plunger Pros as soon as possible so we can inspect the issue and help prevent bigger repairs later.

  • How much does underground leak detection cost?

    The cost depends on where the leak is, how hard it is to access, and how much testing is needed to confirm the source. We believe in honest, straightforward service, so we will explain the process clearly and let you know what to expect before moving forward. Our team focuses on finding the problem efficiently so you are not paying for unnecessary work.

  • Do you repair the leak after you find it?

    Yes. We do not just locate underground leaks. We can also handle the plumbing repair once the source is confirmed. Depending on the situation, that may involve spot repair, rerouting a water line, or other solutions that make sense for your home and budget. We will explain your options in plain language so you can make the right decision with confidence.
