Ask this question in a pool owners forum and you will get twenty answers, a few horror stories, and at least one person who paid twice for the same leak. Ask most pool companies and you will get "it depends," which is true and also useless.
Here is a straighter answer. National cost guides like HomeGuide and Angi put professional pool leak detection between $100 and $1,000, with most inground pools landing in the $400 to $1,000 range depending on the pool and the process. Some companies charge less for a single line test, more for a full leak detection with a spa attached.
This post breaks down what drives that price up or down, what a real leak detection service includes, and how to make sure you only pay for detection once.
The Number That Matters More Than the Price: One Visit or Two
Most providers won't tell you this, but the biggest cost variable in leak detection is not the pool. It is whether the company finds the leak the first time.
A cheap "leak check" that misses the leak location is the most expensive option on the market. You pay for the visit, keep losing water, watch the water bill climb, then pay someone else to do it right. We see this pattern constantly: the second call is the real one.
That is why Level Up quotes every job as a flat rate before we start. Not hourly. The quote you hear is the price you pay, whether your leak shows itself in twenty minutes or hides in complex plumbing for three hours. Hourly detection punishes you for having a hard leak. Flat-rate detection puts the pressure on the tech, where it belongs.
"People call asking what we charge, and I get it. The better question is what you get for it. A full detection with a written report is the cheapest thing that happens to a leaking pool. The expensive thing is guessing, patching the wrong spot, and refilling the pool for six more months."

What Affects Pool Leak Detection Cost
Whether you call us, a national franchise like American Leak Detection (ALD), or a local pool company, these are the factors that move the price:
One factor that should never be on this list: tearing up your deck or landscape to find the leak. Modern detection is non-invasive. If a company's plan to locate leaks starts with cutting concrete, get a second opinion before they start.
What a Full Leak Detection Includes
When pool owners compare prices, they are often comparing different services. Here is what a complete leak detection process looks like at Level Up, and what the flat rate covers:
- Confirm the leak. We verify the pool is leaking, not just losing water to evaporation. If you want a head start, run a free bucket test first. Our guide on how to tell if your pool has a leak shows you how.
- Pressure test only if needed. If listening and dye testing haven't isolated the leak, we pressurize the suspect pipe on its own — skimmer, main drain, return, or cleaner line — to confirm or rule out underground plumbing.
- Listen with LeakTronics gear. Our tech uses hydrophone equipment to hear the leak through the swimming pool shell and plumbing without draining a drop.
- Confirm with dye. A dye test at each suspect spot (cracks, fittings, skimmer throat, light niches) proves the exact culprit before anyone quotes a repair.
- Written report. You get documentation of what we found and where, which is yours to keep whether we do the repair or not.
That last point answers a common question: yes, we find and repair. Detection and pool repair are separate line items, so you are never forced to bundle. But since the same team that found your leak quotes the fix, nothing gets lost in translation.
Detection Cost vs. the Cost of Waiting
Worried the detection fee is not worth it? Run the other math. A small leak losing an eighth of an inch of water per day quietly drains thousands of gallons a season. That is water, chemicals, and heat you pay to replace, plus a water bill that creeps up month after month. And leaks do not heal. A pinhole in a fitting today can undermine the pool shell or wash out soil under the deck by next year.
Industry cost guides put typical pool leak repair between a few hundred dollars for a simple fitting or liner patch and four figures for structural leaks. Every month of waiting pushes your repair toward the expensive end. Finding the leak early is not the costly decision. Waiting is.
