Pool Leak Detection Contractors

The most reliable test is the bucket test. Place a bucket of pool water on your pool step, mark the water levels inside and outside, and check after 24 hours. If the pool water dropped more than the bucket water, you likely have a leak. Other signs include unexplained water loss exceeding a quarter inch per day, air bubbles in return lines, cracks in the pool deck, wet spots in the yard near pool plumbing, and constantly running auto-fill systems.

Professional pool leak detection typically costs between $150 and $500 depending on the complexity of your pool system and your location. Most companies charge a flat diagnostic fee. If a leak is found in the plumbing, repairs are usually quoted separately and can range from $300 to $2,500+ depending on accessibility and the type of repair needed.

Many pool leaks can be repaired without fully draining the pool. Shell cracks and fitting leaks are often patched underwater using specialized epoxy or putty. Plumbing leaks may require excavation of the affected pipe section, but the pool itself often does not need to be drained. Your detection specialist will advise on the least invasive repair approach based on the leak location.

A professional leak detection inspection typically takes 1 to 3 hours depending on the size and complexity of your pool, the number of plumbing lines, and whether the leak is readily identifiable. Some complex situations with multiple leaks or hard-to-access plumbing may require a follow-up visit.
