Pool Closing & Winterization Guide for Georgia Homeowners

Peachy Pools provides pool closing and winterization services for homeowners across Cobb, Paulding, and Cherokee counties in Georgia. If you are wondering when to close your pool, how to winterize your equipment, or whether Georgia pools even need winterization, this guide covers everything you need to know based on 15 years of closing pools in North Georgia.

I am Corey Adams, owner of Peachy Pools, and every fall I help homeowners in Kennesaw, Marietta, and the surrounding area properly shut down their pools for winter. Pool closing in Georgia is different from up north. We do not get months of solid freezing, but we do get unpredictable freeze-thaw cycles that can crack pipes, damage pump housings, and ruin filters if your pool is not protected. A proper winterization prevents thousands of dollars in spring repair bills.

Do Georgia Pools Need Winterization?

Yes. This is the most common misconception I hear from homeowners who moved to Georgia from warmer states. North Georgia sits in USDA Zone 7b to 8a, which means we regularly see overnight temperatures in the low 20s and occasionally into the teens between December and February. Cobb County averages 35 to 40 nights below freezing each winter. That is more than enough to freeze standing water in pipes, crack PVC fittings, and damage pump seals.

The danger in Georgia is specifically the freeze-thaw cycle. Unlike Minnesota where everything stays frozen for months, our temperatures swing above and below freezing repeatedly. Water expands when it freezes, contracts when it thaws, and that constant cycling puts tremendous stress on plumbing connections, equipment housings, and tile lines. I repair more freeze damage from Georgia's erratic winters than you might expect.

When to Close Your Pool in Georgia

The ideal time to close a pool in North Georgia is late October to mid-November. You want water temperatures consistently below 60°F before you winterize, because warmer water still supports algae growth and burns through winter chemicals faster. But you also want to close before the first hard freeze, which in Cobb County typically arrives in mid-to-late November.

If you are still swimming in October because of warm weather, that is fine. But do not push your closing past mid-November. I have seen homeowners in Acworth and Woodstock wait until December and then scramble after an unexpected hard freeze cracks a pipe. By then you are paying for an emergency repair on top of the closing service.

Pool Closing Checklist for Georgia Homeowners

This is the exact process I follow when closing pools across Cobb, Paulding, and Cherokee counties. Whether you handle it yourself or hire a professional, every step matters.

Step 1: Deep Clean the Pool

Before you shut anything down, get the pool as clean as possible. Skim the surface, vacuum the floor, and brush the walls and tile line thoroughly. Any debris left in the pool over winter becomes staining, and organic matter feeds algae growth even in cold water. Pay extra attention to the waterline tile — Georgia's red clay dust and pollen residue will permanently stain if left sitting for months.

Step 2: Balance Water Chemistry

Properly balanced water protects your pool surfaces and equipment all winter. Test and adjust to these ranges:

If your calcium hardness is low going into winter, the water will pull calcium from your plaster, leaving etching marks that are expensive to fix. I see this every spring in pools that were not properly balanced before closing.

Step 3: Shock the Pool

Shock with calcium hypochlorite at 3 times the normal dose. This kills any bacteria or algae spores in the water and provides a high chlorine reserve that slowly depletes over winter. Run the pump for at least 8 hours after shocking to ensure full circulation. Do this 24 to 48 hours before you plan to add algaecide and close — you need the chlorine level to drop below 5 ppm before adding algaecide, or it will neutralize the algaecide on contact.

Step 4: Add Winterizing Chemicals

After the chlorine drops below 5 ppm, add a winter algaecide (copper-based or polyquat, not linear quat which can foam). In Georgia, I also recommend a metal sequestrant if your well water has high iron content — many homes in Dallas and Hiram in Paulding County have well water with elevated metals that cause staining over winter.

Step 5: Lower the Water Level

Lower the water 4 to 6 inches below the skimmer opening. This prevents water from entering the skimmer and freezing in the skimmer body and plumbing lines. Do not drain the pool completely — the water weight holds the pool shell in place against hydrostatic pressure from groundwater. In areas with Georgia's red clay soil, a completely drained pool can actually float or shift.

Step 6: Blow Out and Plug the Lines

This is the single most important step for freeze protection. Use a shop vac or air compressor to blow all water out of the return lines, skimmer lines, and main drain line. As each line clears, immediately install a winter plug or expansion plug to seal it. Any water left in underground plumbing will freeze, expand, and crack the pipe. I see this repair every spring — a cracked underground return line that costs $800 to $1,500 to excavate and replace.

Step 7: Drain All Equipment

Remove the drain plugs from your pump, filter, heater, and salt chlorine generator (if you have one). Tip the pump slightly to drain any remaining water. Open the air relief valve on your filter. If you have a DE or cartridge filter, remove the internal elements, clean them, and store them indoors. For sand filters, set the multiport valve to the winterize position (between two settings so the internal spider gasket is not compressed all winter). Store all drain plugs in the pump strainer basket so you can find them in spring.

Step 8: Protect the Equipment Pad

Cover exposed equipment with breathable equipment covers or tarps. Do not use airtight plastic wrap — it traps moisture and causes corrosion. If your equipment pad is exposed to the northwest (the direction most of our winter weather comes from in North Georgia), consider adding a windbreak. Disconnect the power to the pump at the breaker and turn off the heater gas supply.

Step 9: Install the Winter Cover

Use a solid winter cover or a safety cover. Mesh safety covers are better for Georgia because they allow rainwater to pass through (we get plenty of winter rain) while keeping leaves and debris out. Solid covers require a cover pump to remove standing water after rain — if you forget to pump off the rainwater, the cover can collapse into the pool under the weight.

Pool Closing Mistakes I See Every Year

After 15 years of opening pools in spring and seeing the damage from bad winter closings, these are the mistakes that cost homeowners the most money.

How Much Does Pool Closing Cost in Georgia?

Professional pool closing in Cobb, Paulding, and Cherokee counties typically costs $200 to $400 depending on pool size, equipment complexity, and the type of cover. A basic closing for a standard residential pool with a mesh cover runs around $250. If you have a heater, salt system, and automatic cleaner that all need to be properly drained and stored, expect to be closer to $350 to $400.

Compare that to the cost of freeze damage repairs: a cracked pump housing runs $300 to $600, a cracked underground pipe runs $800 to $1,500, and a cracked filter tank runs $400 to $1,200. One bad freeze without proper winterization can easily cost more than five years of professional closing services. For homeowners in Canton and Powder Springs and the higher elevations of Cherokee County, freeze risk is even greater — those areas consistently run 3 to 5 degrees colder than downtown Atlanta on winter nights.

DIY Pool Closing vs Hiring a Professional

If you have an air compressor or powerful shop vac and are comfortable working with pool plumbing, you can close your own pool. The chemical supplies (shock, algaecide, metal sequestrant) run about $50 to $80, and winter plugs are $2 to $5 each. The whole process takes 3 to 5 hours the first time, and about 2 to 3 hours once you have done it before.

That said, the consequences of making a mistake are expensive. If you do not blow out every line completely, if you miss a drain plug, or if you skip the metal sequestrant and get staining — you are looking at repair costs in the spring that dwarf the $250 to $400 you would have spent on a professional closing. I recommend DIY closing only if you have the right tools and are confident in the process. If there is any doubt, hire a pro.

Winter Pool Maintenance in Georgia

Even after closing, your pool needs occasional attention through the winter. Georgia winters are mild enough that algae can still grow during warm spells, and our winter storms drop leaves and debris on covers.

Georgia's winter is short enough that some pool owners in Smyrna and Vinings choose to keep their pools running on reduced pump schedules through winter rather than fully closing. This is an option if you have a variable-speed pump and are willing to maintain chemistry, but you still need to protect against freeze events. Running the pump during freezing temperatures keeps water moving and prevents freezing, but if the power goes out during a freeze you have no protection at all.

When to Open Your Pool After Winter

In North Georgia, plan to open your pool in mid-to-late March. Water temperatures typically reach the 55 to 60°F range by then, and you want to get the pool circulating before pollen season hits in early April. For a detailed step-by-step guide to spring opening, see our Spring Pool Opening Checklist for Georgia.
