Liner leak detections are performed using the Leak Track 2200. This device uses the most advanced technology available. We have operated this device for over 9 years and have become one of the few certified experts operating this device. This service is available on both in and above ground vinyl liner pools. The cost for this service starts at $190.00 for above ground pools and $290.00 in ground pools. These prices are approximate and subject to change based on location, pool size , and other variables. There is no need to drain the pool for the testing or repair of the liner.
