Yes. Hire a licensed contractor for pool leak detection, especially if the company may also be testing plumbing, operating equipment, diving the pool, or giving repair recommendations.
Leak detection is not just walking around with dye. A real leak evaluation may involve pressure testing pool plumbing, checking the skimmer, inspecting the light niche, testing fittings, evaluating equipment, and deciding whether the pool is losing water through plumbing, the shell, or another area. Those decisions affect what repair gets done next.
The risk of hiring someone unlicensed is not only that they may miss the leak. The bigger risk is that they may give the wrong answer, cause damage, recommend the wrong repair, or leave the customer with no real accountability.
Local vs. Certified License
Some pool leak work may be done under a local county or municipal license, depending on where the person is working and what the local rules allow. But if a company is working across multiple counties, a Florida certified contractor license matters.
Leak and Subsurface Locators holds Florida Certified Pool/Spa Contractor license CPC1457277. We serve multiple counties, so that licensing matters to us and to our customers.
