Pool opening (spring service)
Also known as: spring opening, seasonal opening
Comprehensive seasonal service to prepare a pool for use after winter closure. Includes equipment startup, water rebalancing, debris removal, and chemistry adjustment.
Pool opening is the spring service that prepares a closed pool for the swimming season. Typical scope: remove and store winter cover, vacuum/skim accumulated debris, reinstall removed equipment (ladders, diving boards, pump baskets), inspect and start filtration system, balance water chemistry, shock and stabilize chlorine levels.
For an in-ground pool, opening typically takes 2-4 hours of crew time plus return visits over 1-2 weeks for chemistry monitoring. Above-ground pools take less time. Customers typically pay $250-$500 per opening, with more complex pools (water features, heaters, chillers, automation) running higher.
For pool service operators, openings concentrate in a 6-8 week window in spring (typically April-May depending on climate). Capacity planning during this window is critical — too few crew = lost opening business; too many = idle capacity in shoulder months. Many operators bundle opening + closing + summer service contracts to spread opening-season demand and capture year-round customer relationships. Closings are functionally similar (pool draining, equipment storage, winterization, cover installation) at similar pricing.

Cyanuric acid (pool stabilizer)
Pool chemical that protects chlorine from UV degradation. Required for outdoor pools but harmful when over-accumulated. Target range: 30-50 ppm.
Free chlorine vs combined chlorine
Free chlorine is the active sanitizer in pool water. Combined chlorine (chloramines) is chlorine bound to contaminants — irritating and ineffective. Target: free chlorine 1-3 ppm, combined chlorine under 0.5 ppm.
