Pool Leak Repair in Port St. Lucie

Pool leak repair is the second half of a two-step process: first the leak is located with evidence — pressure testing, dye, acoustic pinpointing — then the specific failed component is fixed with a written quote you approve before any work starts. In Port St. Lucie the common repairs land between $300 and $1,500: skimmer joints at $300–$800, light conduits at $300–$650, underground plumbing at $500–$1,500+, and crack work from about $75 per linear foot.

If you haven’t had the leak located yet, start with pool leak detection — the flat $250–$550 diagnostic visit. This page covers what happens after: what we fix, how, and what it honestly costs.

Repair follows evidence, not a hunch

The expensive failure mode in this trade isn’t a bad repair — it’s a good repair of the wrong thing. A tech who “figures it’s probably the skimmer,” epoxies the skimmer, and leaves has cost you a service call and left the actual leak (say, a return line fitting six feet away) running. Two months later the bill is still high and you’re calling someone else.

That’s why we don’t sell repairs standalone. Every repair we quote traces to a documented finding: a plumbing line that failed a 20 PSI pressure test and got pinpointed acoustically, dye visibly pulled into a skimmer throat gap, current tracked through a shell crack. The quote lists what was found and what fixing it costs, per our published pricing. Repairs are performed by licensed, insured Florida pool professionals.

The four repairs Treasure Coast pools actually need

Skimmer leak repair — $300–$800. The skimmer-to-shell joint is where a plastic housing set in the deck meets a concrete shell, and on Port St. Lucie’s 15-to-25-year-old boom pools it’s the most common leak we find. Repairs range from epoxy/sealant restoration of the joint to partial rebuilds; a full skimmer replacement with a deck cut costs more, and we say so up front. Details on the skimmer leak repair page.

Light niche and conduit repair — $300–$650. The pool light sits in a wet niche with an electrical conduit running behind the shell — an open pipe that can quietly siphon water until the pool level rests at the top of the light. The fix is resealing the niche and potting the conduit. Details under pool light leak repair.

Underground plumbing repair — $500–$1,500+. When a buried suction or return line fails the pressure test, acoustic pinpointing marks the break and we open exactly that spot — one clean cut instead of exploratory trenching. Price rides on depth, deck cutting, and how much line gets replaced. Our sandy soil is the villain here: it settles, plumbing settles with it, and escaping water erodes voids that occasionally need filling as part of the job.

Structural crack repair — from ~$75/linear foot. Genuine shell cracks get sealed or injected; larger structural work with staples runs $700–$1,500+. We also check the hydrostatic relief valve in the main drain sump — a Florida-specific fitting that fails like anything else and mimics a shell leak. See pool crack repair.

How repairs work under a pool cage

Most Port St. Lucie pools sit inside a screened enclosure, which means deck cuts happen inside your cage. Our crews treat that as part of the job, not an inconvenience: screen panels protected, concrete dust contained and cleaned up, debris hauled out through the door — not through a panel. Deck material matters to the quote too, and we’re straight about it: pavers lift and relay almost invisibly; broom-finish concrete patches acceptably; stamped or decorative concrete never matches perfectly, and you’ll hear that from us before the saw comes out, not after.

Why waiting makes repairs more expensive

A pool leak is one of the few home problems with a running meter attached. On City of Port St. Lucie’s inclining tier rates — with sewer charges billed on the same metered water — a typical leak costs $50–$150 a month before anyone touches a tool. On a salt pool, the constant fresh-water dilution drags salinity and chemistry down, so you’re buying salt and chemicals on top.

Underground leaks specifically get worse with time in our soil. Escaping water washes fine sand away from the pipe and out from under the deck; what starts as a glue-a-coupling repair can grow into a repair plus a void to fill and pavers to relevel. If your deck already shows sinking or lifting near the pool, or the lawn has a permanently wet stripe, the leak has been running a while — worth booking detection this week, not this quarter.

What a written quote from us looks like

• The finding: which component failed, and the evidence (pressure test result, dye observation, acoustic pinpoint location).
• The fix: exactly what will be done — materials, whether a deck cut is needed and where, and how the deck gets restored.
• The number: itemized if there’s more than one leak, so you can prioritize. (Two leaks on one pool is common at the 20-year mark — an old skimmer and a tired light conduit often fail in the same era.)
• The timeline: most fitting-level repairs are a same-day visit plus epoxy cure time; deck-cut plumbing jobs run one to two days.

You approve it before work starts. If you’d rather take the report to another contractor, that’s fine — the detection fee bought you the diagnosis, and it’s yours.
