Leak Detection in Austin, TX
A hidden water leak doesn’t need to be dramatic to be costly. In Austin – where aging pipes run beneath slabs of shifting Blackland Prairie clay, and where freeze events have quietly stressed plumbing systems across Central Texas for years – the conditions that cause hidden leaks are built into the city itself. A slow drip behind a wall, a failing connection at a water heater, or a supply line losing pressure underground can waste thousands of gallons before it ever shows up as visible damage. By the time most homeowners notice something is wrong, the leak has usually been going for a while.
Beyond Wow Plumbing uses non-invasive technology to locate leaks precisely before anything is cut into or opened up. We cover the full range, water line leaks, slab leaks, and gas leaks, and once we find the source, we walk you through exactly what we found and what comes next before any work begins. We’ve helped more than 250,000 Austin-area homeowners since 1980, and our Gold Collar Team brings the same upfront, no-surprises approach to every leak detection call.
Signs You May Have a Hidden Water Leak

Most leaks don’t announce themselves with a burst pipe or flooded floor. They build slowly, and the early signs are easy to dismiss until the water bill arrives. According to the EPA, a small undetected household leak can waste 90 or more gallons per day, over 10,000 gallons per year, without a single visible puddle.
Signs worth paying attention to:
- An unexplained spike in your water bill with no change in usage
- Damp or discolored patches on walls, ceilings, or flooring
- Musty or mildew odors in rooms that should be dry
- Warm or soft spots on floors with no obvious cause
- The sound of running water when everything in the house is off
- Low water pressure at fixtures throughout the home
- Soggy or unusually green patches in the yard with no recent rain
Any one of these on its own might have an explanation. Multiple together, or one that keeps coming back, usually means a leak worth finding before it gets worse.
Common Places We Find Hidden Leaks in Austin Homes
Leaks don’t always happen where you’d expect. Beyond Wow locates hidden water loss across all of the following:
- Under-slab water and drain lines: One of the most common and hardest-to-detect leak sources in Austin’s older housing stock.
- Water heater connections: Supply and discharge line connections are a frequent source of slow drips that go unnoticed until the surrounding area is already damaged.
- Behind-wall fixture connections: Bathroom and kitchen supply lines feeding sinks, showers, and toilets can develop slow leaks at joints and fittings without ever breaking through the wall.
- Toilet seals and supply lines: A failed wax ring or deteriorating supply line can leak steadily at floor level, often going undetected beneath flooring or behind a toilet base.
- Gas lines: If you smell sulfur or rotten egg odor near an appliance or along a wall, that’s a potential gas leak and requires immediate attention.
How We Find a Leak Without Cutting Into Your Home
The first step is always locating the problem before anything is disturbed. Beyond Wow uses a combination of tools depending on the leak type: acoustic equipment that listens for the sound of escaping water through walls and underground, moisture meters that identify saturation behind surfaces, and thermal imaging that reads temperature changes caused by escaping water. Together they let us identify the source without opening up walls or flooring to look.
Once we know exactly where the leak is, we explain what we found in plain terms before any work is discussed. No pressure, no assumptions. Just a clear picture of what’s happening and what your options are.
What Leak Detection Costs and Why Finding It Early Matters
Leak detection cost depends on several factors: the type of leak, where it’s located, how accessible the line is, and what equipment is needed to pinpoint it. Beyond Wow provides upfront pricing before any work begins so there are no surprises.
What early detection saves is the more important number. A slow leak left unaddressed works on drywall, flooring, insulation, and in the case of under-slab leaks, your foundation. The longer it runs, the more it touches and the more expensive the fix becomes.

Austin Leak Detection FAQs
What are the most common signs of a hidden water leak?
The most common early signs are an unexplained spike in your water bill, damp or discolored spots on walls or ceilings, musty odors, and the sound of running water when nothing is on.
How do I know if I have a slab leak versus another type of leak?
Slab leaks can show up as warm spots on the floor, an unexplained increase in your water bill, or the sound of running water when everything is turned off. Other plumbing leaks may cause damp drywall, water stains, pooling near fixtures or appliances, or other visible signs of moisture.
What affects the cost of leak detection in Austin?
Cost depends on the type of leak, where it's located, how accessible the line is, and what detection equipment the job requires. Beyond Wow provides upfront pricing once we've assessed the situation.
Can a small leak really cause that much damage?
Yes. The EPA estimates a small household leak can waste more than 10,000 gallons per year, and slow leaks work on drywall, flooring, insulation, and foundations over time; the longer they run, the more expensive the fix becomes.
Do you handle gas leak detection as well?
Yes, if you smell sulfur or rotten egg odor near a gas appliance or along a wall, call us immediately. Gas leaks require a different detection process and immediate attention.
Could my plumbing have been damaged by a past freeze without my knowing?
Yes. Freezing temperatures can weaken pipes, fittings, and solder joints without causing an immediate burst. If your home went through a hard freeze and you’re now seeing higher water bills, warm spots, or unexplained moisture, a leak detection inspection is worth scheduling.
How long does leak detection take?
Most visits are completed within a few hours depending on the home's size and the type of leak suspected. Beyond Wow walks you through the findings before any next steps are discussed.
What happens after the leak is found?
Once we've located the source, we walk you through what we found, where it is, and what the repair looks like, including upfront pricing, before any work begins.
