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.

Spas take the most abuse. We specialize in resurfacing, jet repair, and plumbing overhauls to restore your relaxation spot to factory-new condition.
Why San Mateo Homeowners Choose Legendary Pools
Bay Mud & Hydrostatic Pressure Specialists
San Mateo's subterranean geography features a sharp contrast between expansive clay foothill slopes and low-lying coastal flats comprised of soft silt and dense "Bay mud." In areas closer to the lagoon networks and water lines, a naturally high water table exerts immense hydrostatic pressure on subterranean structures. Our engineering frameworks counteract this by incorporating specialized deep-gravel sub-bases, advanced dewatering pumping cycles during excavation, and heavy-duty structural shotcrete shells equipped with dual hydrostatic relief valves.
City of San Mateo Building Division Navigation
The City of San Mateo Building Division enforces strict architectural alignment, safety setbacks, and municipal grading ordinances. We manage 100% of the permit processing and engineering submittals. Because San Mateo heavily monitors urban water discharge into the public bay filtration networks, our designs incorporate custom on-site drainage solutions and zero-permeability retention calculations.
Stormwater & Bay Protection Compliance
To protect the San Francisco Bay ecosystem, San Mateo ordinances strictly prohibit draining pool chemicals or backwash into the municipal storm drain system. All drainage must be routed directly into the household sanitary sewer cleanout using an approved air-gap mechanism. Our plumbing teams engineer this explicitly for every project, ensuring zero environmental impact and full code compliance.
Foothill & Coastal Zone Expertise
San Mateo's geography transitions from historic flat estates near Baywood and San Mateo Park to rolling western ridges near I-280. We have extensive experience engineering pools for both terrains—addressing Bay mud challenges in low-lying areas while applying proper grading and drainage for hillside stability in western neighborhoods.
"Legendary Quality for Every San Mateo Neighborhood"
San Mateo properties deserve pools that reflect their prestige. We deliver architectural-quality pools with resort-level features, premium materials, and the attention to detail that San Mateo estates demand.
