San Jose pool owners contend with a long, hot swim season that stretches well into autumn, putting continuous strain on pumps, filters, and heaters that run for months without a break. The city's varied housing stock means some pools were installed decades ago, when equipment standards and plaster formulations were quite different from what is available today. Older pools in particular tend to develop slow leaks, surface staining, and inefficient single-speed pumps that quietly drive up electricity bills season after season without owners realizing the source.
K&D Quality, Inc. has been based in the South Bay since 1994, and San Jose represents the heart of the service area. Technicians travel from the primary location and are familiar with the range of pool configurations found across the city — from compact backyard pools on smaller lots to larger freeform designs with attached spas. Weekly service visits follow a consistent checklist covering water chemistry, equipment inspection, debris removal, and filter maintenance, so nothing gets missed between appointments.
A San Jose customer who has worked with K&D Quality typically notices the change in a few concrete ways: water stays consistently clear rather than swinging between cloudy and balanced, equipment runs more quietly and cycles off on schedule, and the pool simply requires less owner attention. For households that invested in a salt chlorination system or automation upgrade, the outcome is even more tangible — fewer manual adjustments, fewer surprises, and a backyard that is ready to use without preparation every time.
What We Do in San Jose
Services offered
Weekly Pool Service
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.
