How to Winterize Your Pool (Charleston Edition)

Smart Seasonal Prep for Charleston’s Mild Winters

Charleston SC may not see snow, but your pool still needs winter prep to stay healthy and hassle-free. Unlike colder regions, many local homeowners opt to keep their pool open year-round—yet smart winterization ensures your system stays protected during low-use months.

Why Winterize in Charleston?

  • Prevent algae growth during cooler, slower circulation periods
  • Reduce chemical costs and energy use
  • Protect equipment from freeze damage during cold snaps

Set up for an easier, faster spring opening

Winterization Steps for Charleston Pools

You shouldn’t close your pool for the season.  Instead, keep an eye on it year round, while simply scaling back.  Just follow these steps:

  1. Balance Water Chemistry
    Adjust pH, alkalinity, and calcium hardness. Shock the water to start the season clean.
  2. Clean Thoroughly
    Skim, brush, and vacuum. Clean tile lines and remove any organic debris that could stain or clog.
  3. Backwash and Clean Filter
    Rinse cartridge filters or backwash sand/DE filters to prevent buildup.

Cover the Pool (Optional)
A mesh or solid safety cover keeps debris out and simplifies spring prep—especially helpful under trees.
