How much does pool leak detection cost?
$400 – $1,000 average cost (inground pool)
$100 – $500 average cost (above-ground pool)

Average pool leak detection price
Swimming pool leak detection costs $100 to $1,000 on average, depending on the type of pool, liner material, detection method, and the source of the leak. Hard-to-find leaks or leaks in inground pools cost more than patching a small leak on an above-ground pool.
Pool type | Average cost |
---|---|
Above-ground | $100 – $500 |
Inground | $400 – $1,000 |
Above-ground
Detecting a leak in an above-ground pool costs $100 to $500 in most cases. Since all the components of an above-ground pool are easily visible and accessible, leaks are easier to find and cheaper to fix than ones in inground pools.
Inground
Detecting a leak in an inground pool costs $400 to $1,000 on average. Inground pools are more expensive to inspect than above-ground pools due to complex plumbing and accessibility.
Swimming pool leak detection cost factors
The following factors affect the cost of pool leak detection:
Labor rates: Local labor rates affect what pool technicians charge in your area. Labor accounts for nearly all of the cost of a pool leak detection service, although technicians may charge for using materials like dyes or pool draining tools.
Detection method: Advanced techniques like electronic sensors, ultrasound, or infrared cameras may increase costs.
Extent of the leak: Urgent, large leaks may require emergency or after-hours services, which tend to cost more. However, they could save money in the long run by preventing further damage.
Leak location: The location of the leak affects both the inspection cost and the repair cost. In some cases, an obvious tear in a liner will be easy to find. Otherwise, the technician may need to perform a pressure test in underground pipes or drain the pool to get a better look.
Liner type: Your pool exterior is either made from vinyl, fiberglass, or concrete. Detecting a leak may be harder and cost more in concrete pools than in vinyl or fiberglass.
Inspection: Some technicians check for leaks during a routine inspection. A pool inspection costs $200 to $500 on average.
Common pool leak locations
Leaks can occur in a number of places in and around your pool. Some of the most common areas include:
The main drain
The pump or motor
In between tiles
Plumbing pipes
The pool liner
Around lights
Next steps
Once the pro finds a leak, pool repair costs $500 to $1,500 on average to fix leaks. Some leak detection services include minor repairs, but anything more than that will cost extra.
If the pool technician has to dig to find the source of the leak, the repair costs will be higher. Excavation costs $100 to $300 per hour. However, pressure tests are much less invasive and should catch the problem first.
Test or repair type | Average cost |
---|---|
Pressure test | $150 – $500 |
Liner repair | $100 – $3,600 |
Pool light repair | $70 – $150 per light |
Drain repair | $400 – $1,500 |
Pump repair | $50 – $650 |
Pool tile repair cost | $25 – $30 per square foot |
Pool draining | $70 – $175 |
Pool filling cost | $40 – $2,000 |
Pool resurfacing cost | $6,000 – $15,000 |
FAQs about pool leak detection
How does pool leak detection work?
Pool leak detection begins with simple tests like visual inspections, bucket tests, and dye tests to identify water loss and locate leaks near cracks or fittings. These methods help determine if a leak exists and narrow down its general area.
Professionals use advanced techniques such as pressure testing and electronic acoustic devices to detect leaks in underground pipes or hidden areas. These tools pinpoint the exact leak location, allowing for targeted repairs and preventing further water loss or damage.
How can I minimize detection costs?
To minimize leak detection costs, clear the pool of debris, toys, and floaties, and ensure the water is clean before the inspection. Providing detailed information about symptoms can help technicians locate the leak faster.
How often should I have my pool inspected for leaks?
Professionals recommend annual inspections to catch leaks early and avoid more expensive repairs down the line. Detecting and repairing pool leaks promptly saves water, prevents structural damage, and keeps your pool in top condition. Always consult a qualified pool professional for accurate leak detection and repair.
