Pool Shell, Tile & Light Niche Leak Detection Apache Junction
A crack in the shell, a gap at the tile line and a leak behind a light can all look alike from the deck, yet each one leaks — and each one is fixed — differently. We test them separately: dye along the tile joint, a careful look at shell cracks, and a light-niche check that includes the conduit behind the fitting. A cosmetic mark that holds dye is left alone, while a joint that pulls dye gets sealed. That distinction saves owners from sealing a whole shell for one failed joint. Call (480) 919-8308.

Shell cracks tested – Tile gaps checked – Light niches sealed and proved

Pool shell, tile and light niche leak detection in Apache Junction, AZ – a clear pool being checked for shell and fitting leaks.
Why choose us
Why Choose Our Shell, Tile and Light Niche Service?
Shell and light work is where patience pays, because dye in calm water tells the truth that a dry inspection cannot. The light niche is a special case: water can travel along its conduit and appear far from the fitting, which fools a quick repair. We check the niche, the conduit and the surrounding plaster as one system, and we explain which part failed and which parts are sound. Tile gaps get the same care — a gap that does not pull dye is a cosmetic job for later, not an emergency leak.
Shell Cracks Dye-Tested
Each crack is dye-tested, not just looked at, so only cracks that pull dye are treated as leaks.

Tile-Line Gaps Checked
Tile gaps are checked for water movement behind them, separating cosmetic gaps from fitting leaks.

Light Niches Sealed and Proved
Light seals, gaskets, and conduit are dye-tested, then retested after sealing, so the fix is proved.

Retested Before We Leave
After sealing, the shell, tile, and lights are dye-tested again and the level is checked.

FAQs
Frequently Asked Questions About Shell, Tile and Light Niche Leak Detection
How do you tell a shell crack leak from a cosmetic crack?
Dye testing shows whether water is pulled into the crack. Cosmetic cracks do not pull dye.
Can tile gaps cause a pool leak?
Sometimes. Gaps can hide a fitting leak, but many gaps are cosmetic. Dye testing separates the two.
Why does my pool light fog or leak?
Light gaskets and conduit seals fail with age and heat, and leak slowly into the niche.
How long does shell, tile and light testing take?
Most tests are completed in one visit, depending on the number of cracks, gaps, and lights.
Will sealing a crack stop the loss?
Only if the crack proved faulty. We retest after sealing to prove the fix held.
Do you offer emergency shell, tile and light detection at night?
Yes. We are open 24 hours. Call (480) 919-8308 for fast or sudden water loss at any hour.
