Pool Closing in Gloucester County, NJ: Fall Steps

Across South Jersey—Gloucester City, Clayton, Franklin, and down toward Cape May—fall means one unavoidable chore for pool owners: closing up before the cold sets in. It’s not busywork. Our winters freeze hard enough to turn the water left in your pool’s plumbing into cracked pipes and ruined equipment. Pool closing in Gloucester County, NJ is about getting ahead of that freeze, and it’s very doable if you follow the right steps.

When to close

Close once your water temperature holds steadily below 60°F—usually mid-to-late October in our part of South Jersey. That’s the threshold where algae goes dormant, keeping your water clear under the cover all winter. Close too early during a warm stretch in Woodstown and you’ll get algae; wait too long and an early freeze can crack your lines before you’ve begun.

The step-by-step closing

1. Balance the water a few days ahead—pH 7.2–7.6, alkalinity 80–120 ppm, calcium hardness in range—to protect your surfaces through the winter.
2. Deep-clean—skim, brush, and vacuum. South Jersey’s leaf drop is heavy, and debris left behind stains and feeds algae.
3. Shock and treat—shock the pool, let chlorine normalize, add a winter algaecide.
4. Lower the water below the skimmer and returns.
5. Blow out the lines—clear skimmer, returns, and main drain with a compressor, plug them, and add non-toxic pool antifreeze where needed. Fully drain the pump, filter, and heater.
6. Cover it securely and keep debris and standing water off it all season.

Doing it on a budget without cutting corners

Closing a pool doesn’t have to be expensive, but the temptation to save money in the wrong place is real. Skipping the winter algaecide to save a few dollars, or rushing the blow-out, is exactly how a cheap closing turns into a pricey spring. The smart way to save is to do the easy steps yourself—balancing, cleaning, covering—and put your money and care into the one step that protects the most: clearing every line so nothing freezes and cracks.

The step that matters most

Cracked underground plumbing is the most expensive spring repair we see, and it comes down to water left sitting in the lines over a freeze. Whether you DIY or call us, make sure the blow-out is done thoroughly. It’s the difference between an easy spring opening and a costly one.
