Typical Florida installed cost for pool leak detection: $250–$700 — a curated 2026 planning range, not a bid. The most accurate figure for your home comes from a verified local pro (free, below). In Lee County, pool-adjacent permit activity over the last 90 days was in the 50+ band among records we track — public-record aggregates, not a national guess.
A pool that keeps losing water may be leaking or may just be evaporating — telling them apart is the first job, because Florida sun and wind can pull down the water level all on their own.
Handle it soon — these get more expensive with time.
Common causes:
• A leak at a return, skimmer, or light niche — common spots where fittings and seals fail
• A crack in the shell or a failure in the plumbing lines under the deck
• A torn skimmer throat or a bad valve losing water when the equipment runs
• Plain evaporation, which in Florida's heat and wind can mimic a real leak
• A dig-up-the-deck or shell-crack repair quoted before a proper leak-detection test
• No bucket test or dye test to separate real leaking from evaporation
• No state license number for the structural or plumbing repair work
• Pressure to commit to a big repair before the leak is actually located
How do I know if my pool is leaking or just evaporating?
The bucket test is the classic check: float a bucket of pool water on a step and compare how much the pool drops versus the bucket over a day. If the pool drops faster, you likely have a leak worth locating professionally.
Where do pools usually leak?
Most often at the returns, skimmer, light niche, and plumbing connections rather than the shell itself. Professional leak detection pinpoints it before anyone opens the deck or drains the pool — which is why detection comes before repair.
Pool leak detection: $250–$700 (typical ~$375)
Detection only (dye, pressure, or electronic); the repair itself is separate.
Local permit records we track for Lee County lean toward the "mid-high" cost tier for pool work nearby.

Florida licenses this trade at the STATE level (DBPR / CILB (CPC)). Hiring unlicensed for this work is illegal for the contractor — and risky for you: no permit rights, no insurance backing, no recourse.
Work like this often requires a county permit — a legitimate pro pulls it, not you.
Basis: FL Stat. 489 (DBPR state licensing).
