Pool Repair Near You in San Jose & the South Bay

Common Pool Repairs We Handle Every Day

Pool equipment breaks down without warning. A humming pump that won't prime, a heater that trips its pressure switch, a filter that spikes pressure overnight — these aren't just inconveniences; they can accelerate damage to plumbing and shell surfaces if left alone.

K&D Quality technicians carry stock parts for the most common equipment brands on San Jose pools, including Pentair, Hayward, and Jandy. That means fewer return visits and faster turnaround on most repair calls.

We handle the full range of repair work: pump and motor replacement, filter service and cartridge swaps, heater ignition and heat exchanger issues, salt cell cleaning and replacement, automation board troubleshooting, and leak detection on both plumbing lines and shell surfaces.

• Pump and motor repair or replacement
• Pool heater repair and igniter/gas-valve service
• Filter cleaning, cartridge replacement, and DE grid repair
• Salt chlorinator cell testing and replacement
• Automation and control system troubleshooting
• Leak detection — plumbing lines and shell
• Plaster crack patching and fiberglass resurfacing

Serving San Jose and Every Corner of the South Bay

San Jose's pool season runs longer than most of California — the Santa Clara Valley's inland heat means pools are actively used from late March through October, putting more annual hours on equipment than coastal markets. That extended run time is why pump seals, filter media, and heater igniters wear faster here than manufacturers' average estimates suggest.

Many homes in established San Jose neighborhoods like Willow Glen, Almaden Valley, and Cambrian Park were built in the 1960s through 1980s with older plumbing configurations — galvanized or early PVC lines that may need updated fittings during a repair call. We account for that reality when we quote the job.

San Jose pools also sit in a seismically active zone. The Bay Area's occasional ground movement can stress underground plumbing fittings and expansion joints, making periodic leak checks especially useful. If you've noticed your water bill climb without an obvious cause, a pressure test is a low-cost first step before assuming the worst.

How a Repair Call Works

When you call K&D Quality, a technician — not an answering service — gathers enough detail to arrive with the right parts. We schedule a site visit, inspect the equipment or area you've flagged, and give you a written diagnosis before any work begins.

If the repair is straightforward, we complete it the same visit. If parts need to be ordered or a more involved fix is required (resurfacing, underground pipe repair), we walk you through the scope, timeline, and cost before you commit to anything.

There are no surprise add-ons after the fact. If we find something additional during the repair, we tell you what it is, what it would cost to address, and let you decide.

When to Call Versus Wait

Some pool problems are fine to monitor for a day or two. Others need a technician the same week to avoid compounding damage or safety issues. Here is a simple way to think about urgency.

Call soon if: your pump runs but pulls no water (cavitation damages the impeller fast), your heater shows a fault code or gas smell, your water is dropping more than a quarter-inch per day (normal evaporation in the South Bay heat is roughly one-eighth to one-quarter inch — more than that suggests a leak), or your automation panel has gone unresponsive.

Can usually wait a short window: a single torn cartridge filter fin, mild algae growth without equipment failure, cosmetic plaster discoloration without cracking. Even for lower-urgency items, scheduling sooner means the job gets done before your pool season peaks.

• Pump cavitating or running dry — call promptly
• Heater fault codes or gas smell — call promptly
• Water loss above a quarter-inch per day — schedule a leak check
• Automation panel unresponsive — schedule soon
• Filter or minor cosmetic issues — schedule at your convenience
