A pool acid wash in Encino can bring back plaster that has gone gray, brown or chalky, but only when the finish underneath is still sound. A thin layer of the surface comes off with the stains, and there is a limit to how many washes a pool can take. (Source: Leslie's)
So we check the plaster first and recommend a wash only when it will help, and we are upfront that replastering and resurfacing are outside the work we do.
Pool Acid Wash in Encino: What Makes It Different
Encino pools face two common kinds of staining. Leaves from the native oaks that fill the hills south of Ventura Boulevard leave brown organic marks where they settle, and LADWP's Valley water adds calcium, with 2025 average hardness of about 103 to 140 mg/L across the sources that serve Encino. (Source: LADWP) Each summer of evaporation and top-offs leaves more of that calcium behind.
Plaster age varies too. The city's historic survey dates most Encino neighborhoods to the years after World War II, with hillside homes following from the late 1950s through the 1970s. (Source: LA City Planning, SurveyLA) Pools behind them were built and refinished at many different times, so we judge the surface, not the house.
Drainage is the rule to get right. Under the City of Los Angeles stormwater code, pool water may go to the storm drain only once it is dechlorinated or debrominated. (Source: Los Angeles Municipal Code) Storm drains carry water to rivers and the ocean untreated (Source: LA County Public Works), and Encino sits in the Los Angeles River watershed, which stretches from the San Fernando Valley to the harbor in Long Beach. (Source: LA County) The river itself runs through the Sepulveda Basin on Encino's northern edge.

A pool acid wash in Encino follows the steps on our pool acid wash service page:
- Stain diagnosis. Organic, metal or mineral, and whether the plaster can take a wash.
- A legal drain route. Water dechlorinated and sent only where City rules allow.
- Sectioned wash, neutralized rinse. Acid applied a section at a time, with rinse water neutralized before it leaves the pool.
- Refill and start-up. Fresh water balanced for calcium and pH from day one.
Timing Your Acid Wash in Encino
Because a pool acid wash in Encino ends with a full refill of LADWP water, timing affects your bill. LADWP does not discount water for filling a pool, but customers may qualify for a Sewer Service Charge adjustment when the pool is filled during the rainy season, typically October through April. (Source: LADWP) Cooler months are also kinder to freshly exposed plaster than a midsummer heat wave, though we still watch the forecast so an empty pool never sits through a heavy storm.
If only the waterline is scaled, our tile and calcium cleaning may be all you need, with no drain at all. The full list of services is on the Pool Cleaning Los Angeles homepage.
