Pool Repair on the Treasure Coast

A pool that’s losing water, cracking, or shedding tile doesn’t always need a whole new surface. Often it needs the right repair, done in the right order. Pool repair starts with diagnosis: finding what’s actually wrong, why it happened, and whether fixing it now will hold or just delay a bigger job. This page explains how contractors track down leaks, tell cosmetic cracks from structural ones, deal with hollow spots, and repair tile, coping and the bond beam, and how to decide between a repair and a full resurface. When you’re ready, we’ll connect you with a licensed Treasure Coast contractor.

Leak detection and what causes leaks in Florida pools

First, is it a leak or evaporation?

Florida heat, sun and wind pull a surprising amount of water out of a pool, so a dropping water level isn’t automatically a leak. The simplest check is the bucket test. Set a bucket on a pool step, fill it with pool water to the same level as the pool, and mark both water lines. Run the pump on its normal schedule, and compare the two after a day. Both lose water to evaporation at about the same rate, so if the pool has dropped noticeably more than the bucket, you’re probably losing water somewhere else.

If your pool has an automatic fill valve, keep an eye on it. An auto-fill can quietly replace leaking water for months, and the first sign is often a higher water bill rather than a lower pool.

Where pools usually leak

• Fittings in the shell. The skimmer, return jets, main drain and light niches are all places where pipe or conduit meets the pool shell, and the seals around them can fail with age and ground movement.
• Underground plumbing. The lines running between the pool and the equipment can crack or separate at joints, especially where soil has settled or tree roots have grown in.
• The equipment pad. Pump seals, valves, filter connections and heaters can drip. These are the easiest leaks to spot, so check around the equipment for damp ground or standing water first.
• Cracks in the shell. Less common than fitting and plumbing leaks, but more serious, and covered in the next section.

How the pool loses water gives useful clues. If it loses more with the pump running, the leak is often on the pressure side of the plumbing, the lines carrying water back to the pool. If the level drops to a certain point and stops, the leak is often at that height, such as the skimmer or a light. Note what you’ve observed before a contractor visits. It can shorten the search.

How contractors find leaks

Professional leak detection narrows things down in stages. A contractor may squeeze a small amount of dye near suspected fittings and cracks and watch whether it gets drawn in. They may seal off individual plumbing lines and pressure-test them to see which one won’t hold pressure. And they may use electronic listening equipment to pinpoint a leak in a buried line before anything is dug up. Finding the exact spot matters, because it’s the difference between a small targeted repair and tearing up a deck on a guess.

Cracks: cosmetic versus structural

Not all cracks mean the same thing, and the repair depends on which kind you have and what caused it.

Where the crack is tells you a lot

• Cracks confined to the finish are usually shrinkage or wear in the surface layer. They’re cosmetic, and they’re typically dealt with by patching or during the next resurface.
• Cracks at the corners of steps and benches can be surface-only or can follow a weak point in the shell. They’re worth watching closely.
• Cracks along the tile line often point to movement at the top of the pool, where the deck meets the coping. See the bond beam section below.
• Cracks through the shell itself are structural. They may come from soil settlement, pressure from groundwater under the pool, or movement of the surrounding deck, and they can leak.

Is it growing?

A crack that’s stable is a very different problem from one that’s still moving. A simple way to tell is to mark both ends of the crack with a waterproof marker or a piece of tape and note the date. If it extends past your marks over the following weeks, the cause is still active, and that needs to be understood before any repair.

How structural cracks are repaired

For a structural crack, the pool is usually drained so the crack can be opened up and repaired properly. Depending on the crack and the contractor, that may involve cutting out along the crack and filling it with a repair material, injecting it to seal it through its depth, or stitching across it with steel staples set into the shell to hold both sides together before it’s patched. The finish over the repair is then restored. A patch on a colored or aggregate finish rarely matches perfectly, which is one reason structural repairs and resurfacing often end up happening together.

Whatever the method, the cause has to be addressed too. A crack repaired without fixing the settlement or deck movement behind it will often come back.

Hollow spots and delamination

A hollow spot means the finish has come loose from the shell underneath. Sometimes the original finish never bonded well when it was applied. Sometimes water has worked in behind it, or years of unbalanced chemistry have weakened it. Left alone, a hollow area tends to grow, and eventually it cracks open and flakes away, leaving sharp edges that can cut feet.

When a patch makes sense

If there are only one or two small hollow areas and the rest of the finish is well bonded, a contractor can cut the loose section out back to solid material and patch it. The patch will likely be visible, especially on colored and aggregate finishes, but it restores a safe, sealed surface.

When it doesn’t

If hollow spots show up in several places, the bond across the whole finish is probably weakening. Cutting out one area often exposes more loose finish around it, and patches keep failing at their edges. At that point, repeated patching costs more over time than dealing with it once, and the better answer is usually removing the old finish and resurfacing.

Tile, coping and bond beam repair

The bond beam is the thick top edge of the pool shell. It carries the waterline tile on the inside and the coping stones along the top. Problems here usually show up as tiles popping loose, grout washing out, coping that rocks or cracks, or a crack running along the tile line.

The expansion joint is often the culprit

Between the coping and the pool deck there’s usually a flexible joint that lets the deck move independently of the pool. When that sealant dries out and cracks, water gets in behind the coping, and a deck that expands in the heat can push directly against the bond beam. Over time that shows up as loose coping, cracked tile and cracks at the top of the pool. Replacing a failed expansion joint is a small job compared with the damage it prevents, so it’s worth having checked whenever tile or coping problems appear.

How the repairs work

• Loose tiles and failing grout can often be reset and regrouted in sections, sometimes with the water lowered rather than fully drained.
• Loose or cracked coping is removed, the bed underneath is cleaned up, and the coping is reset or replaced.
• Bond beam damage, such as cracked or crumbling concrete or rusting reinforcement, has to be repaired first. The tile and coping are then reset on a sound base.
• White crusty deposits on the tile are usually calcium scale rather than damage. They can often be removed by bead blasting, a cleaning method that doesn’t require replacing the tile.

If your tile or coping is at the end of its life rather than needing spot repair, see our page on tile and coping replacement.

Pool repair or resurfacing? How to tell

This is the decision most homeowners are really facing, and it usually comes down to a few questions, asked in this order.

1. Is the structure sound?

Leaks, structural cracks and bond beam damage come first, no matter what. A new finish applied over an active leak or a moving crack is money spent twice. If there’s a structural problem, fix it before you think about the surface.

2. Is the surface problem isolated or widespread?

One damaged area on an otherwise healthy finish is a repair. Hollow spots, roughness or staining spread across the pool mean the finish itself is failing, and patching will keep chasing new problems.

3. Does the repair mean draining the pool anyway?

Draining, prep and refilling are a large share of the effort in any resurface. If a structural or fitting repair already requires emptying the pool, and the finish is getting old, that’s often the most economical moment to resurface at the same time rather than drain again in a year or two.

4. Will a patch be acceptable to you?

Repairs on white plaster can blend reasonably well. On colored, quartz or pebble finishes, patches are usually visible. If an obvious patch would bother you, factor that in.

If the answers point toward a new surface, our guide to pool resurfacing walks through the full process, and replastering covers the traditional plaster option. Still unsure? Read the signs that a finish is at the end of its life, or look at how repair and resurfacing costs compare.

FAQs

Can I keep using my pool while it’s leaking?

Often, yes, for a slow leak, as long as the water level stays above the skimmer so the pump doesn’t run dry. The exception is anything involving a pool light: if water loss seems connected to a light, or the light is behaving oddly, turn it off and have it checked before anyone swims.

Can repairs be done without draining the pool?

Some can. Small chips, individual tiles and some fitting repairs can often be handled with the water in or partly lowered, using materials designed to cure underwater. Structural cracks, widespread delamination and bond beam work generally need the pool drained so the repair can be done properly.

Does homeowners insurance cover pool leaks and cracks?

It depends entirely on your policy. Many policies treat sudden damage differently from gradual wear or settling, and pools may have their own terms. Check your policy or ask your agent before assuming either way.

Does pool repair need a permit?

It depends on your city or county and on the work involved, particularly when plumbing, electrical or structural work is part of the job. Your contractor should know the rules for your address and pull any permit that’s needed. If you’re in Port St. Lucie, our page on pool work in Port St. Lucie explains how the city handles pool permits.
