An Approach to Successfully Closing Your Above Ground Pool

Stepwise Approach to Successfully Closing Your Above Ground Pool

Closing your above ground pool as the season turns is not just a routine task—it’s a crucial step in safeguarding your investment. When temperatures drop, unprotected pools can suffer from damage due to freezing water and debris accumulation. Our guide ensures that you approach this task with confidence, preserving the pristine condition of your pool during the off-season.

We also have a guide explaining the difference between closing and winterizing inground pools. Check it out here!!

Step 1: Balancing Act – Water Chemistry and Accessory Care

Fine-Tuning Your Pool’s Water – Before anything else, it’s vital to get the water chemistry right. Adjusting the pH, alkalinity, and chlorine levels is not just about maintaining clear water—it’s about protecting the pool’s liner from damage and preventing algae from taking hold.

Accessory Roundup – Pool ladders, slides, toys, and other accessories should be cleaned and stowed away. This not only extends their lifespan but also keeps the pool area uncluttered and safe.

Step 2: The Deep Clean – Vacuuming and Adding Chemicals

Scrub and Vacuum – A thorough clean-up of your pool is essential. This includes brushing down the walls and vacuuming the floor to remove any lurking debris and algae.

Winterizing Chemical Magic – Post-cleaning, it’s time to add winterizing chemicals. These are specifically formulated to maintain water quality and prevent freezing damage during the colder months.

Step 3: Water Level Wizardry

Optimal Water Levels for Winter – Adjusting the water level is a critical step. It should be lowered to just below the skimmer to prevent freezing damage. For those preferring not to lower the water level, skimmer guards or custom-designed stoppers can be used to protect the skimmer from ice damage.

Step 4: Pump and Filter Prep

Securing the Pump and Motor – The heart of your pool, the pump and motor, needs attention too. Draining and disconnecting them prevents freezing and cracking during winter.

Filter Focus – Taking apart and cleaning the filters is a task not to be missed. This is an excellent opportunity to inspect, clean, or replace filters to ensure smooth operation next season.

Step 5: The Final Touch – Pool Covering

Ensuring a Snug Fit – The final step in the process involves closing your above ground pool with a sturdy, weather-resistant cover. This shields your pool from debris and the elements, ensuring it remains clean and protected.
