Swimming Pool Facilities & ServicesExpert pool design, construction, and repair services families love.

Swimming Pool Design
Real design means sitting in your backyard and figuring out where the sun hits and how the land slopes.
Pool Construction
We've been doing pool construction in the Bay Area since before half these new builders were born. We know the clay soil, the codes, and how to build a gunite pool that lasts forever.
Heater Installations
Want to use your pool year-round? We install gas heaters for speed, heat pumps for efficiency, and solar for the free sun. All permits and gas lines handled by our pro crew.
Pool Pump Repair Installation
The heart of your pool. When it dies, everything stops. We fix noisy motors and install high-efficiency variable speed pumps that can save you $50-75 a month on PG&E.
Valve Repair Replacement
Leaking valves waste water and money. We handle broken handles, cracked bodies, and frozen diverters same-day, stocking most common parts to get you back in business fast.
Filter Repair Installation
Your pool's kidney. We repair cartridge, sand, and DE filters, dealing with everything from cracked tanks to eucalyptus debris common in the Bay Area.
Pool Renovations
Turn your tired old pool into a modern oasis. We replaster, retile, and upgrade equipment to make your pool look brand new and cost half as much to run.
Spa Restoration
Spas take the most abuse. We specialize in resurfacing, jet repair, and plumbing overhauls to restore your relaxation spot to factory-new condition.
Why Gilroy Homeowners Choose Legendary Pools
Heavy Clay & Agricultural Soil Specialists
The geographical basin of Gilroy features thick layers of expansive agricultural clay soil and high sediment deposits. This soil type requires heavy-duty engineering solutions to prevent structural shifts during shifting seasonal moisture levels. Our build crews utilize reinforced structural rebar grids and increased concrete floor thicknesses specifically designed for these challenging soil conditions.
Private Well & Septic System Setback Experts
Many custom Gilroy estates operate on private water wells and underground septic tank fields. Our engineers meticulously structure excavation maps to comply with mandatory environmental safety setbacks—ensuring zero interference with your property's utility infrastructure. We maintain the required 15-foot minimum from septic tanks and 25-foot minimum from leach fields.
Agricultural Runoff & Irrigation Protection
Securing approval for a swimming pool in Gilroy involves coordinating structural blueprints with specific drainage guidelines designed to protect adjacent agricultural lands and public water systems. We manage the entire submittal and engineering phase with the City of Gilroy Building Division, incorporating custom grading plans to control stormwater responsibly on-site.
Extreme Heat Pool Management
With summer temperatures regularly reaching into the 90s, chlorine evaporation happens much faster in Gilroy. We highly recommend installing fully automated saltwater chlorinators or UV sanitization loops paired with variable-speed pumps to keep pool water perfectly balanced, clear, and cool throughout the intense heat spikes that characterize Gilroy summers.
"Legendary Quality for Every Gilroy Neighborhood"
Atherton properties deserve pools that reflect their prestige. We deliver architectural-quality pools with resort-level features, premium materials, and the attention to detail that Atherton estates demand.

This heavy-duty engineering prevents structural shifts during shifting seasonal moisture levels, ensuring your pool maintains integrity for generations.
Septic & Well System Setback Compliance
We meticulously structure excavation maps to comply with mandatory environmental safety setbacks required by Santa Clara County and City of Gilroy building codes. This includes maintaining the required 15-foot minimum setback from septic tanks and 25-foot minimum from septic disposal fields (leach fields), ensuring zero interference with your property's utility infrastructure.
Agricultural Stormwater Management
Every pool layout we construct incorporates custom grading plans to control stormwater responsibly on-site. This protects adjacent agricultural lands and public water systems from pool runoff, ensuring your pool project maintains good relationships with neighboring farmland and complies with Gilroy Building Division drainage requirements.

For Gilroy's signature warm summers with temperatures regularly reaching the 90s, we recommend fully automated saltwater chlorinators or UV sanitization loops. These systems pair with variable-speed pumps to keep pool water perfectly balanced, clear, and cool throughout intense heat spikes while minimizing chemical evaporation and maintenance requirements.
