Swimming Pool Leak Detection and Repair in Marble Falls, TX

June 17, 2026

A pool leak is one of those problems that starts small and gets worse fast. Maybe you notice the water level dropping more than normal. Maybe your water bill creeps up. Or maybe you spot wet areas in the yard that should not be there. Whatever the first clue is, ignoring a pool leak never ends well.

In the Texas Hill Country, the soil shifts, the sun bakes, and the ground moves. All of that puts stress on your swimming pool. Cracks form. Fittings loosen. Plumbing lines age. And before long, you are losing water, money, and peace of mind.

At Pool Smart, we provide professional pool leak detection and leak repair in Marble Falls and the surrounding Hill Country. Our team uses advanced leak detection tools to find the root cause of your leak fast, without damaging your deck or landscape. Then we fix it right the first time with long-lasting repair solutions.

Call us today at (512) 577-9835 for a pool leak inspection.

Common Causes of Pool Leaks in the Hill Country

Pool leaks do not just happen for no reason. There is always a root cause, and knowing what to look for can help you catch a problem early. Here are the most common causes we see in Marble Falls, TX and the Hill Country:

  • Aging plumbing. Over time, the plumbing lines under and around your pool can crack, shift, or corrode. PVC joints and fittings are common weak spots, especially in older pools.
  • Ground movement. The Texas Hill Country sits on limestone. Soil shifts, settling, and drought cycles put pressure on your pool shell and can open cracks in the walls or floor.
  • Skimmer and fitting leaks. The seals around your skimmer, returns, lights, and drains can break down over time. A light conduit leak is one of the most common issues we find during an inspection.
  • Structural cracks. Temperature swings, soil shifts, and age can all cause cracks in the pool shell. Even hairline cracks can lead to big water loss over time.
  • Plumbing leaks in hidden lines. Some of the hardest leaks to find are in hidden plumbing under the deck or buried in the ground. These leaks can go unnoticed for months and lead to structural damage.

If you spot any of these leak issues, do not wait. Early detection saves you money and keeps your pool safe.

Signs Your Swimming Pool May Have a Leak

Not sure if your pool has a leak or if it is just normal water loss from the Texas heat? Here are the telltale signs:

  • Water level drops more than a quarter inch per day. Some loss from the sun is normal, but anything beyond that could signal a leak.
  • High water bills. A sudden spike in your water bill is one of the first signs many Marble Falls homeowners notice.
  • Wet areas around the pool. Soggy spots in the grass, damp soil near the equipment pad, or puddles on the deck are all red flags.
  • Air bubbles in the return jets. This often means air is getting sucked into the plumbing through a crack or loose fitting.
  • Cracks in the pool shell or deck. Visible cracks in the plaster, tile, or coping can be entry points for leaks.
  • Autofill running nonstop. If your autofill system is always on, your pool is losing water faster than it should.
  • Algae that keeps coming back. Constant water loss throws off your chemistry. If you cannot keep the pool balanced, a leak may be the reason.

How Pool Smart Handles Advanced Leak Detection in Marble Falls

Finding a pool leak is not always simple. Water can travel far from the actual source, making it hard to tell where the problem really is. That is why Pool Smart uses advanced leak detection methods that are both accurate and non-invasive.

Here is what our leak detection process looks like:

Step 1: Visual Inspection

Our technician starts with a full visual inspection of the pool, deck, and equipment area. We look for cracks, wet areas, loose fittings, and any other signs of trouble. This first step often narrows down the search area before we bring in the advanced tools.

Step 2: Pressure Testing

We run pressure testing on the plumbing lines to find out if the leak is in the pipes. Each line is tested one at a time so we can isolate exactly which run has the issue. This is one of the best ways to diagnose hidden plumbing leaks without digging.

Step 3: Electronic Listening Devices

We use professional-grade listening devices that can hear the sound of water escaping through a crack or joint. These advanced tools let us pinpoint the leak to within inches, even in buried plumbing lines.

Step 4: Dye Testing

For shell cracks, skimmer joints, and light conduit areas, we use dye testing. A small amount of dye is placed near a suspect spot. If there is a leak, the dye gets pulled into the crack, showing us exactly where water is getting out.

Step 5: Accurate Diagnostics and Report

Once we find the leak, we give you a clear report of what is wrong, where the problem is, and what it will take to fix it. No guesswork. No surprise costs. Just honest, accurate diagnostics so you can make a smart choice.

"The key to a good repair is finding the exact source. We do not guess. We test, we listen, and we confirm before any repair work starts." - Pool Smart Team

Pool Leak Repair Solutions That Last

Once we find the leak, we fix it. Pool Smart offers repair solutions built for the long haul. Our goal is to solve the problem with as little downtime and disruption as we can.

Here are some of the repair methods we use:

  • Fitting and skimmer repair. We seal or replace cracked fittings, skimmer bodies, and return lines. These are some of the most common repairs we do.
  • Shell crack repair. For cracks in the pool shell, we use underwater epoxy, staple stitching, or other proven methods to restore the structure without damaging your pool.
  • Pipe repair and reroute. If the leak is in a buried plumbing line, we can reroute the line or use our no-dig pipe repair method to seal the pipe from the inside, without excavation.
  • Light conduit leak repair. Pool lights are a frequent leak point. We seal or replace the conduit to stop water loss at the source.
  • Deck and joint sealing. If water is getting in through expansion joints or cracks in the deck, we seal those areas to prevent further damage.

Every repair we do is followed by a retest to make sure the fix holds. We do not leave until we are sure the leak is gone.

Why Professional Leak Detection Matters

Some homeowners try to find and fix pool leaks on their own. While DIY bucket tests can confirm that you have a leak, they cannot tell you where the leak is or how bad it is. Here is why professional service makes all the difference:

  • Saves time. A professional leak detection visit can find the source in hours, not days.
  • Saves money. Fixing the right spot the first time means you do not waste money on repairs that miss the mark.
  • No damage. Our non-invasive methods mean we do not have to tear up your deck, landscape, or pool to find the issue.
  • Prevents bigger problems. A small leak left alone can lead to equipment issues, structural damage, and thousands of dollars in wasted water and repairs.

Pool leak detection in Marble Falls is not something to put off. The sooner you call for leak detection Marble Falls repair services, the less it costs to fix.
