Winter is coming, and that means it’s time to winterize your pool! But you may be asking, isn’t it hard winterizing my pool? That depends on the equipment you have, the location of your pool, and how handy you are. If you need to winterize your pool, knowing how to do this on your own will save you hundreds of dollars a year.
Properly closing your pool protects it from cold-weather damage, prevents costly repairs, and makes reopening in the spring much easier. At True Blue Leak Detection, we’re here to help guide you through the process. Follow this simple, step-by-step guide to ensure your pool is ready to weather the off-season.
Why Is Winterizing My Pool Important?
Winterizing prevents freeze damage to your pool equipment and plumbing, winterizing keeps your water clean, and it protects your pool’s surfaces from algae, stains, and scaling. Skipping this essential step can lead to expensive repairs when you reopen in the spring.

Step-by-Step Guide to Winterizing My Pool
Step 1: Remove Pool Accessories
Start by removing skimmer baskets, ladders, diving board, pool toys, and solar blankets. Clean and dry them, then store them in a safe, dry place for the winter.
Some ladders are permanent, but many can come out if you unscrew the bolts holding them in.
Here’s a simple video showing you how to take out your ladder:
Step 2: Deep Clean Your Pool
Get rid of leaves, dirt, and debris using a skimmer net and vacuum. Brush the walls and floor to prevent algae and staining during the colder months.
If you’ve been staying on top of your pool maintenance all summer, this shouldn’t take you too long.
However, if you let many of the leaves and debris fall from the trees sit in your pool for a while, this process can take several or hours to do.
Step 3: Test and Balance Water Chemistry
Balanced water chemistry is crucial for pool protection. Adjust your levels to these targets:
- pH: 7.2–7.6
- Total Alkalinity: 80–150 ppm
- Calcium Hardness: 175–275 ppm
Add the necessary chemicals to achieve the correct balance and prevent scaling and corrosion.
If you don’t know how to do this, just take a sample of your pool water to a pool supply store like Leslie’s and they can set up a plan for you to balance your chemicals for free… The plan is free, not the chemicals, lol.
Step 4: Shock Your Pool
Apply a pool shock treatment to kill bacteria and contaminants. Run your pump for at least 4 hours to distribute the chemicals evenly.
Step 5: Add Winterizing Chemicals
Introduce an algaecide to keep algae at bay and consider adding stain and scale preventers to protect your pool surfaces.
There are many types you can add. Some chemicals go in once at closing while others sit in your pool and slowly release chemicals all winter long.
Step 6: Lower the Water Level
Drain the water to just below the skimmer or tile line, depending on your pool type and cover. This leaves room for precipitation and prevents freezing damage.
Step 7: Drain Pool Equipment
Turn off and unplug your pump, heater, and filter. Drain all water from the equipment and store removable components indoors if possible.

Step 8: Blow Out the Water Lines
This step is a lot more advanced and may require some equipment you don’t have. If you are not comfortable with this step, absolutely call a professional. Warning: If you don’t blow out the water properly in your plumbing, your pipes may freeze causing a very expensive repair. This includes all of your equipment, including your heater.
Use a blower or shop vac to remove water from your plumbing lines. For extra protection, add pool antifreeze to prevent freezing in areas where water might linger.
Here’s a great video on that process:
Step 9: Cover Your Pool
Install a durable pool cover to keep out debris and sunlight. A tight, secure cover also protects your pool from harsh winter weather.
