Pool Resurfacing in Los Angeles County, From the Westside to the Foothills
Aqua Creations brings pool resurfacing to Los Angeles County homes, hotels, apartment buildings, and HOA pools from our shop in Ventura. Our own in-house crews apply every AQUA-GLASS™ fiberglass finish, and we have resurfaced pools across Southern California since 1991.
Backyard pool project
Commercial pool resurfacing in Los Angeles starts with the right health agency
Hotels, apartment buildings, HOAs, and clubs answer to a health agency before a resurfaced pool reopens. Across the towns we cover, four different agencies hold that role, and the city the pool sits in decides which one.
Los Angeles County Department of Public Health
Its Recreational Waters Program reviews construction plans for new public pools and for renovations of existing ones, and its inspectors look at pool walls, floors, and main drains. The county sends Pasadena, Long Beach, and Vernon pools to their own local rules.
Pasadena Public Health Department
Its Environmental Health Division regulates public swimming pools inside the city. Plans go to the division first, and it says construction or renovation should not begin until they are approved.
Long Beach Health and Human Services
The city’s Public Pool and Spa Program issues permits, inspects pools each year, and runs its own plan check reviews, which it says include remodels and re-plastering.
San Bernardino County Environmental Health Services
Rancho Cucamonga is in San Bernardino County. The county’s public pool guide asks to be notified even when a pool is only re-plastered, and it calls for white plaster or another approved finish.
Public pools follow the health agency’s approved finish rules, so we do not offer custom colors on hotel, apartment, or HOA pools. We review the agency’s requirements with you up front, including the main drain covers.

More than 20 degrees separate the beach from the foothills in August
Los Angeles County is not one climate. NOAA’s Santa Monica Pier station has a normal August high of 69.7°F. The Pasadena station’s is 91.3°F. Long Beach Airport and downtown Los Angeles sit in between at 83°F and 84°F, and the foothill towns along the San Gabriel Mountains run closer to Pasadena than to the beach.
For a pool, the hot side of the county means more water lost to evaporation through the summer. The minerals stay behind, and every top-off brings in more, which is why scale and rough plaster show up sooner on many inland pools. Coastal pools see milder heat and more marine air instead.
Rain matters too. Pasadena averages about 20 inches a year, most of it from December through March, while Long Beach averages about 12. A resurfacing schedule in the foothills has more winter weather to work around.

One county, very different fill water
How hard your pool water starts out depends on who delivers it. Water from the Los Angeles Aqueduct and local wells tends to run softer than the imported blend the Metropolitan Water District treats and sells to cities across the region.
| Water supplier | Towns on our list | Average hardness | Report |
|---|---|---|---|
| LADWP, Los Angeles Aqueduct Filtration Plant | Brentwood, Bel Air, Pacific Palisades | 103 mg/L (about 6 grains per gallon) | 2025 data |
| City of Arcadia groundwater | Arcadia | 210 mg/L (about 12 grains per gallon) | 2024 report |
| Pasadena Water and Power | Pasadena, parts of Altadena | 222 ppm (about 13 grains per gallon; range 12 to 15) | 2025 data |
| Metropolitan Water District, Weymouth plant | Imported water blended into many local systems | 234 mg/L (about 14 grains per gallon) | 2025 data |
A new surface goes into service with whatever water the hose delivers. Test and balance the fill water against your own supplier’s numbers rather than a generic target, and watch the waterline, where scale from hard water shows first. One milligram per liter equals one part per million.

Brentwood sits on the Western Los Angeles system of LADWP, which is fed by Los Angeles Aqueduct water that averaged 103 mg/L hardness in 2025. That is well under the imported water most of the county blends in.

WestsideLA County
Pacific Palisades
The closest of our Los Angeles County towns to the ocean. NOAA’s Santa Monica Pier station has a normal August high of 69.7°F, about 22 degrees cooler than Pasadena, so summer evaporation runs gentler here.
Pacific Palisades pool resurfacing -
WestsideLA County
Bel Air
A City of Los Angeles neighborhood on LADWP water. Club, HOA, and other public pools here go through the county’s Recreational Waters Program, not a city health office.

WestsideLA County
Culver City
Golden State Water serves Culver City with imported Colorado River and State Water Project water delivered through the Metropolitan Water District.

Pasadena
Pasadena runs its own public health department, so hotel, apartment, and HOA pools here go through the city instead of the county. Fill water comes from Pasadena Water and Power.
Pasadena pool resurfacing -
FoothillsLA County
Altadena
Three independent water companies serve most of Altadena, and Pasadena Water and Power covers some sections, so fill water depends on which part of town the pool is in.

Verdugo HillsLA County
Glendale
Glendale Water & Power, the city’s own utility, publishes its own yearly water quality report. Public pools in Glendale fall under the county program, unlike next-door Pasadena.
