Fontana Pool Builders provides professional pool leak detection & crack repair in Fontana, CA for residential and commercial properties across the Inland Empire. Pool leak detection in Fontana starts with proving there is actually a leak, because an Inland Empire pool loses roughly a third of an inch a day to evaporation in an August heat wave and that is physics rather than plumbing.
Losing an inch a day is a leak. The bucket test settles it in 24 hours: float a bucket of pool water on a step, mark the level inside and outside, come back tomorrow and compare the two drops.
Same drop means a hot week and a dry wind. Pool dropping faster means it is worth a phone call, and at California water rates a slow leak is an expensive thing to live with for a season.
Once we know there is a leak, finding it is methodical rather than magical. We isolate and pressure test each plumbing line independently, which immediately narrows it to the suction side, a return line, the main drain, or the shell.
We dye test the shell, skimmer throats, light niches, return fittings, and the spa dam wall. On suspected underground breaks we use listening equipment so we open one small section of deck rather than trenching the yard. Locally the findings follow a pattern.
Skimmer throat cracks are the most common single finding, driven by settlement and by the wide daily temperature swings this valley gets. Plumbing sheared where a line crosses from compacted fill to native alluvial gravel is the second.
Light conduit failing at the deck penetration after years of hard UV is the third.
And on older pools we do occasionally find shell cracks associated with ground movement, which in a seismically active corridor between the San Andreas, San Jacinto, and Cucamonga systems is not a surprise.
Structural cracks get staples across the crack plus epoxy or polyurethane injection, never a cosmetic plaster patch over something still moving. Patching a live crack relocates the failure and costs you the job twice.
With 15+ years of experience, our licensed and insured team brings the right materials and equipment to every job — custom 3D pool design, gunite and shotcrete shells, C-53 licensed pool construction, Lytle Creek alluvial cobble excavation, pebble, mini-pebble and quartz interior finishes, glass and porcelain waterline tile — and backs the work with a written workmanship warranty. We serve Fontana and nearby communities including San Bernardino, Ontario, Rancho Cucamonga, Pomona.

Materials, equipment and how we do pool leak detection & crack repair
The difference between pool leak detection & crack repair that lasts and pool leak detection & crack repair that gets redone in three years is almost always preparation and materials, not the finish you see on day one. We work with custom 3D pool design, gunite and shotcrete shells, C-53 licensed pool construction, Lytle Creek alluvial cobble excavation, spec them to the job instead of to the invoice, and write the material grades into the free estimate so you know exactly what you are buying.
Every Fontana job runs the same way: site walk and measurements, written scope and fixed price, protection of the surrounding area, then the work itself with a daily clean-up. 15+ years of pool work in the Inland Empire means we have already met whatever your property is going to throw at us — awkward access, older construction, an HOA with opinions.
