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
Whether you’re closing your pool or simply scaling back for the season, follow these steps:
- Balance Water Chemistry
Adjust pH, alkalinity, and calcium hardness. Shock the water to start the season clean. - Lower Water Level (if closing)
Drop water below the skimmer line to protect plumbing—especially for fiberglass or concrete pools. - Clean Thoroughly
Skim, brush, and vacuum. Clean tile lines and remove any organic debris that could stain or clog. - Backwash and Clean Filter
Rinse cartridge filters or backwash sand/DE filters to prevent buildup. - Drain and Store Equipment
Remove and drain any detachable equipment like heaters, pumps, and chlorinators (if not in use).
Cover the Pool (Optional)
A mesh or solid safety cover keeps debris out and simplifies spring prep—especially helpful under trees.
