We aim to offer same-day diagnostics and repairs for most cases. After locating the leak, we provide a transparent estimate and can start work promptly to prevent further water loss.
Does leak detection impact pool safety or water quality?
No. We use non-toxic, approved sealants and methods that follow the Centers for Disease Control and Prevention guidelines to preserve water safety and hygiene—see their Healthy Swimming recommendations.

Minor cracks or joint leaks can often be sealed underwater in a few hours. Larger or structural leaks may require draining and rebuilding and can take 1–2 days depending on severity.
