Pool Tile
Remodel
Waterline tile takes more chemical and UV exposure than any other surface on the pool. When grout fails, tiles crack, or the bond deteriorates, water moves behind the tile and into the shell. We repair and replace pool tile properly — starting with why it failed before any new tile goes on.
Tile Fails for a Reason — We Find It First
Waterline tile sits at the most chemically active zone of the pool — right at the waterline where evaporation, chemical concentration, and UV exposure are highest. When the grout deteriorates or the bond between the tile and the shell weakens, tiles begin to crack, pop off, and allow water to migrate behind the surface.
Most tile failures we see are symptoms of underlying bond or movement issues — not just surface wear.
Most tile failures we see are not random. They're caused by a deteriorated bond coat, soil movement flexing the shell, or grout that has been chemically compromised over time. Replacing tile without understanding the cause means the new tile fails for the same reason. And that failure usually happens faster the second time.
We assess the full condition of the waterline — the bond coat, the substrate behind the tile, and any shell movement — before recommending any scope of tile work. The repair comes before the new tile, not after.
With over 20,000 repairs completed across DFW, we've seen how often tile is replaced without addressing the underlying failure — and how quickly those installations fail again.

The Right Scope Starts With the Right Assessment
Whether the damage is isolated to one section or spread across the full waterline, the scope of work is determined by the condition of the substrate and what's driving the failure — not just how many tiles have come off.
Section Tile Repair
When damage is isolated to one area — a section of cracked or missing tiles — we remove the failed tiles, assess the substrate and grout behind them, and install new tile with properly prepared bonding and ensure proper adhesion to the prepared substrate. Matching existing tile where possible.
Full Waterline Tile Replacement
When tile is extensively damaged, delaminating across multiple sections, or simply outdated, full waterline replacement is the right scope. We remove the full existing tile run, prepare the substrate properly, and install new tile with fresh grout and sealant throughout — resulting in a consistent, properly sealed waterline.
Tile & Coping Combination
Waterline tile and pool coping fail together more often than separately — they're in the same zone, under the same stresses, and one failing usually signals the other is close behind. We assess and address both in the same project scope when needed, addressing both components in the same sequence and restoring the full perimeter properly.
How It Works
We don't replace tile without understanding why the existing tile failed.
Waterline Assessment
We inspect the full waterline condition — tile condition, grout integrity, bond coat adhesion, and any signs of shell movement or water intrusion behind the surface. We confirm this through inspection of the bond and substrate — not just visible tile damage.
Written Repair Estimate
You receive a clear written estimate before any work begins. Scope — section repair or full replacement — material options, and timeline all in writing before we touch anything.
Tile Removal & Substrate Prep
We remove the existing tile and assess the substrate behind it. Any bond coat failures or shell issues are addressed before new tile is set. This step is what determines whether the new tile holds or fails prematurely.
Tile Installation
New tile is set, grouted, and sealed using materials appropriate for continuous waterline exposure. Every joint is filled and finished to prevent water intrusion behind the new surface.
Written Warranty Issued
Every tile remodel is backed in writing. 3-year warranty on seal-related and associated repair work. Transferable to new homeowners at no additional cost.
If something isn't right, we come back. That's not a policy — it's how we operate.
Written Warranties on Every Repair & Structural Component
Every repair is backed in writing, with clear coverage and real accountability. Warranties are transferable to new homeowners at no additional cost — a documented asset at closing.
Pool Tile Remodel — FAQ
The most common causes include deteriorated thinset or bond coat that loses adhesion over time, grout failure from chemical exposure, and soil movement that causes the shell to flex — breaking the bond between the tile and the substrate. In DFW, freeze-thaw cycles are also a major factor: water gets behind the tile, freezes, expands, and pushes tiles off. Once tiles start coming off in one area, the surrounding tiles are usually compromised as well.
Pool tile itself can last 15 to 20 years or more — but the grout and bond coat behind it often fail sooner. In DFW pools, we typically see tile failures start around the 10 to 15 year mark due to chemical exposure and soil movement. Regular maintenance of grout and proper water chemistry can extend tile life significantly. When the bond behind the tile fails, even tiles that look fine will start coming loose.
The water level needs to be lowered below the tile line, but a full drain is not always required. For waterline tile replacement, we lower the water several inches below the work area. For more extensive tile work that requires substrate repair, or if tiles extend deeper into the pool, more water removal may be needed. We confirm the exact requirement based on your pool's configuration.
We make every effort to source matching tile. Older or discontinued lines can be difficult to match exactly — and we'll be upfront about that during the estimate phase. Even when we find the same tile, existing tile has weathered and faded, so new tile may not match perfectly in color. In some cases, replacing the full waterline run with consistent new tile produces a better result than patch-matching sections that won't align perfectly.
It depends on the underlying condition. If the failure is truly isolated — a single impact crack, for example — section repair makes sense. But if multiple tiles are coming loose or the bond coat is failing in multiple areas, more will follow. We tap-test the surrounding tiles to check for hollow spots (which indicate the bond has failed even if the tile hasn't fallen off yet). If the underlying failure is widespread, full replacement is more cost-effective than repeated section repairs.
Yes — and in many cases it makes sense to do them together. The tile and coping are in the same zone, often failing for the same reasons, and combining the scope avoids having to lower and raise the water level twice. We assess both during the initial inspection and recommend combined scope when the coping shows signs of movement, cracking, or deterioration.
The white crusty deposits you see at the waterline are calcium scale — mineral buildup from hard water and evaporation. It's a cosmetic issue, not a structural one, and can usually be cleaned off with tile cleaning or light acid washing. However, if the buildup is severe and persistent, it may indicate water chemistry problems that are also affecting your grout and tile adhesion. We can assess whether the tile itself needs attention or if cleaning will resolve it.
For a single loose tile, a homeowner with tile-setting experience can sometimes reattach it with appropriate thinset or silicone. But for anything more than one or two isolated tiles, we don't recommend DIY. Pool tile installation requires proper substrate preparation, pool-rated adhesives, and correct grout application. The most common DIY failure we see is tiles reattached without addressing the substrate — which means they come off again, usually within a year.
Porcelain and ceramic tiles rated for pool use are the most common choices — durable, chemical-resistant, and cost-effective. Glass tile offers a distinctive look and excellent durability but costs more and requires experienced installation. Natural stone can be used but requires sealing and more maintenance. Whatever material you choose, it must be rated for pool use — regular bathroom tile won't hold up to constant water exposure and pool chemicals.
A section tile repair can typically be completed in one to two days. A full waterline tile replacement, depending on pool size and tile selection, generally takes three to five days including cure time. If we need to address substrate damage, crack repair, or coping replacement in the same scope, the timeline extends accordingly. We'll give you a clear timeline in the written estimate.
It depends on where the leak is actually coming from. If water is getting behind the tile through failed grout and cracked tiles — yes, proper tile replacement will address that. But waterline leaks can also come from the skimmer throat, the bond beam, or cracks in the shell that happen to run through the tile zone. We assess the leak source first before recommending any tile scope. Replacing tile over an undiagnosed leak just buries the problem.
When tiles come loose and grout fails, water migrates behind the tile and into the bond beam and shell. That water carries pool chemicals with it, accelerating deterioration of the substrate. Over time, this can cause bond beam damage, horizontal cracking, and structural issues that are far more expensive to repair than the tile itself. The sooner failing tile is addressed, the simpler and less expensive the repair.
