Losing an inch of water on a hot day is normal evaporation. Losing two to three inches a week, or noticing the auto-fill running constantly, points to a leak somewhere in the shell or plumbing. The tricky part is that pool leaks rarely announce their location—a structural crack at a light niche can drain a pool as effectively as a failed underground return line, and both look the same from the water surface. Soft ground around the equipment pad, algae returning in the same spot after treatment, or a sudden drop in water level after the pump shuts off are all signs worth investigating before the loss compounds.
Leak detection at K&D Quality uses pressure testing and dye testing rather than guesswork. Skimmer lines, main drain, return lines, and dedicated cleaner lines are isolated and pressure-tested with calibrated rigs to confirm whether each line holds. Structural leak points—light niches, skimmer throats, the tile line—are probed with dye to watch where water movement pulls it. The visit ends with a written report that identifies confirmed leak locations, includes photographs, and attaches a repair quote for what was found. Repairs are scoped and priced separately so the homeowner knows exactly what was located and what it will cost to fix before any ground is broken.
Leak detection in San Jose pools is particularly useful before a resurfacing or renovation project, since repairing a plumbing leak after new plaster is applied is significantly more disruptive than doing it beforehand. It's also worth doing before assuming a pool shell needs major structural work—a slow drain traced to a failing skimmer throat gasket is a straightforward repair, not a structural failure. The outcome of a thorough leak detection visit is clarity: a homeowner who knows exactly where water is going, has documentation of the findings, and can make a repair decision based on confirmed facts rather than a contractor's best guess.

Full-service weekly maintenance on a fixed route day. Includes brushing walls and tile line, vacuuming as needed, skimmer and pump basket emptying, filter pressure check, water testing for chlorine, pH, alkalinity, cyanuric acid, and salt, and chemical balancing. Equipment is visually inspected every visit and you get a text or email if anything's off. Same tech every week, never subcontracted. Most San Jose pools fall between $165 and $235 per month depending on size and tree cover.
Diagnosis and repair on every major brand: Pentair, Hayward, Polaris, Jandy, Sta-Rite, Zodiac, Raypak. Pumps, motors, filters, valves, plumbing, timers, pressure switches, unions, and o-rings. The parts that fail first ride on our truck, so most repairs close in a single visit. We tell you what's worth fixing and what's worth replacing, with the actual cost difference in writing before any work starts.
Full pool resurfacing for plaster pools showing stains, rough spots, hollow areas, or 15-plus years of wear, and fiberglass refinishing for gel-coat fading and osmotic blisters. Process includes drain, chip-out or prep, bond coat, new plaster or gel coat, fill and start-up chemistry over the first 28 days. Typical residential job runs 7 to 10 working days plus fill time. We coordinate the whole job, no separate contractors to chase.
Service and repair on attached spas and standalone hot tubs. Heater diagnosis, circulation pump replacement, jet repair, control pack swaps, cover lifter installs, and full drain-and-refills with line flush. We work on Sundance, Hot Spring, Caldera, Jacuzzi, and most older builder-grade attached spas. If the spa shares equipment with the pool, we already know the plumbing. Most diagnostic visits run under an hour and end with a clear written quote.
Salt cell diagnosis, descaling, replacement, and full new-system installation. We install and service Pentair IntelliChlor, Hayward AquaRite, Jandy AquaPure, and CircuPool. Existing cell scaled out? We test cell output and plate condition before quoting a replacement, plenty of cells just need a proper acid bath. New install on a chlorine pool typically runs $1,800 to $2,400 installed for a residential South Bay pool, including the cell, control board, flow switch, and plumbing.
Gas heater and heat pump repair on Raypak, Pentair MasterTemp, Hayward Universal H-Series, and Jandy LXi and JXi. Common fixes: ignition control modules, pressure switches, gas valves, thermal regulators, heat exchangers. We also install replacement heaters and run new gas lines through licensed sub when needed. Cold pool the week before a party? We carry the most-failed parts and most repairs finish same day. Full replacement installs run 1 to 2 days.
