Year-round service is the norm, at a gentler winter cadence. Hard water is the defining chemistry issue in most of the state — calcium scale on tile, spillways, and salt cells — so good techs track hardness and recommend partial drains before etching starts. Wildfire ash events mean extra filter cleans some falls. The coast swims May through October (heaters stretch it), while the Central Valley and desert run hot enough for six-plus unassisted months. Pools stay open all year, winter is mild, and evaporation — not freeze — is the seasonal enemy, especially inland.

Ask for a written visit checklist and price sheet, then confirm test reporting, skipped-visit policy, chemical surcharges and how repairs are billed. For a saltwater pool, get the cell inspection and cleaning schedule in writing. Between visits, Pool School's chemistry guides and the volume calculator help you follow the trend yourself.

Weekly is the standard cadence during May through October along the coast, longer inland; heavy use, storms, trees and high temperatures may call for extra brushing or testing between visits. Pools here run year-round, so most routes move to a lighter winter schedule rather than stopping.
A full-service visit includes water testing and balancing, skimming, brushing the walls and tile line, vacuuming as needed, emptying skimmer and pump baskets, checking filter pressure and looking over the pump, filter, heater and salt cell. Filter deep-cleans, salt-cell cleaning, algae treatments, tile blasting and repairs are commonly separate line items — ask for the price sheet.
A green-to-clean recovery in San Marcos typically runs $325–$625: shock treatments over several visits, brushing, vacuuming to waste and a filter deep-clean ($85–$175). A pool that sat untreated for a season, or a stained one, may be cheaper to drain, acid wash and refill at $600–$1,400. Get a firm quote after a water test rather than over the phone.

DIY chemicals typically run $50–$100 a month plus your time and a good test kit; a service adds trained eyes on the equipment every week and catches small leaks, failing seals and filter problems before they become repairs. Many owners split the work — a service handles chemistry and equipment while a robotic cleaner handles the floor between visits.
Most residential routes are month-to-month or season-to-season, but terms vary. Check notice requirements, skipped-visit policies, chemical surcharges, filter-clean fees and how minor parts are billed before enrolling — those details usually matter more than a small difference in the base rate.
