San Jose Pool Pros provides professional pool leak detection & repair in San Jose, CA for residential and commercial properties across the South Bay. Pool leak detection in Santa Clara County is worth doing quickly for a reason that goes well beyond the water bill: saturated adobe clay under a slab, a deck, or a house foundation is an expensive structural problem, and a slow underground pool leak is one of the more reliable ways to create one.
A pool losing an inch a day is also losing chemicals and heat continuously and running your auto-fill constantly, so the cost compounds in several directions at once.
We start by confirming there is a leak at all, using a bucket test, because ordinary summer evaporation accounts for more suspected leaks than anything else and nobody should pay for detection they do not need.
Once a leak is confirmed we find it rather than guess at it.
We isolate and pressure-test each plumbing line independently, use electronic listening equipment to trace runs beneath decking and hardscape, and dye-test the shell, skimmer throats, light niches, main drains, tile line, and return fittings.
The usual suspects are a short list: a cracked skimmer throat where the plastic meets the concrete, failed plumbing at or just below the pump pad, the conduit seal behind a light niche, a return fitting that has separated from the shell, or the joint at a spa spillway.
The local speciality is soil movement.
Expansive clay expands through a wet winter and shrinks through a dry summer with enough force to shear an underground line, crack a shell, or open a joint with no other cause present, which is why leaks in this valley often appear after a heavy rain year rather than during use.
We repair all of it — plumbing, structural cracks, skimmer replacement, niche seals — and when the correct fix is repiping a run rather than patching it again, we will say so even though the patch is the easier sale.
With 15+ years of experience, our licensed and insured team brings the right materials and equipment to every job — gunite and shotcrete construction, PebbleTec and pebble aggregate finishes, polished quartz plaster, saltwater chlorination, variable-speed pumps, cartridge and DE filtration — and backs the work with a written workmanship warranty. We serve San Jose and nearby communities including Santa Clara, Sunnyvale, Cupertino, Milpitas.

Materials, equipment and how we do pool leak detection & repair
The difference between pool leak detection & repair that lasts and pool leak detection & repair that gets redone in three years is almost always preparation and materials, not the finish you see on day one. We work with gunite and shotcrete construction, PebbleTec and pebble aggregate finishes, polished quartz plaster, saltwater chlorination, 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 San Jose 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 South Bay means we have already met whatever your property is going to throw at us — awkward access, older construction, an HOA with opinions.
