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 Hillsborough Homeowners Choose Legendary Pools
Grade Beam & Sub-Structural Piering Specialists
Hillsborough's premier properties are often situated on expansive, rolling hillside parcels characterized by dense clay matrices and unstable topsoils. Our master blueprints integrate heavy-duty structural shotcrete shells locked into place using interlocking grade beams and deep-drilled concrete piers. This elite foundation design prevents structural settling, shields your pool from subterranean soil movement, and guarantees that multi-level terrace water features or infinity pools maintain perfect level baselines indefinitely.
Architecture and Design Review Board (ADRB) Experts
The Town of Hillsborough Building Department and the Architecture and Design Review Board (ADRB) enforce some of the most rigorous zoning guidelines in Northern California. We manage the entire submittal process, preparing detailed site line analysis, color rendering reviews, and comprehensive heritage tree root protection plans for local ancient Live Oaks and Redwoods. Our 100% ADRB approval rate reflects deep understanding of Hillsborough's exacting standards.
Acoustic Engineering & Decibel Threshold Compliance
Our mechanical layouts utilize hyper-efficient variable-speed pump pads encased in acoustically treated sound enclosures to easily surpass local residential decibel thresholds at the property line and satisfy California Title 24 mandates. This acoustic engineering ensures your estate pool equipment operates silently, maintaining the tranquil character of Hillsborough's residential neighborhoods.
Creek Watershed & Drainage Protection
Hillsborough heavily protects its local creeks and natural watersheds. Draining chemical-laden pool water into storm drains or open landscape channels is strictly prohibited. All filtration backwash and draining lines must be tied directly into the home's sanitary sewer lateral using an approved air-gap assembly. We engineer this compliance explicitly for every Hillsborough project.
"Legendary Quality for Every Hillsborough Neighborhood"
Hillsborough properties deserve pools that reflect their prestige. We deliver architectural-quality pools with resort-level features, premium materials, and the attention to detail that Hillsborough estates demand.

Why Choose Legendary Pools in Hillsborough:
Interlocking Grade Beam Engineering
Our master blueprints integrate heavy-duty structural shotcrete shells locked into place using interlocking grade beams specifically designed for Hillsborough's dense clay matrices and unstable topsoils. Combined with deep-drilled concrete piers anchoring to firm bedrock, this engineering prevents structural settling and shields your pool from subterranean soil movement indefinitely.
ADRB Submittal & Approval Process
We prepare detailed site line analysis, color rendering reviews, and comprehensive heritage tree root protection plans for submission to the Architecture and Design Review Board. Our 100% approval rate reflects deep understanding of Hillsborough's exacting standards regarding visual impact, color palettes, and architectural integration with the natural landscape.
Heritage Tree Protection (TPZ Protocols)
We develop comprehensive heritage tree root protection plans for local ancient Live Oaks and Redwoods, mapping Critical Root Zones and implementing specialized excavation techniques that preserve tree health while allowing pool construction in close proximity to these protected specimens.
Air-Gap & Creek Watershed Compliance
All filtration backwash and draining lines must be tied directly into the home's sanitary sewer lateral using an approved air-gap assembly. This protects Hillsborough's local creeks and natural watersheds from chemical-laden pool water, ensuring full compliance with town environmental protection ordinances.
