A Step-by-Step Checklist for Closing Your Pool Safely

Closing down your backyard retreat at the end of the swim season is about more than putting away the water toys. Proper pool closing in Pennsylvania is the single best way to safeguard your investment against freeze damage, harsh winter weather, and costly spring repairs. Because the same local team that builds our pools also services them, we know exactly what it takes to protect your equipment and water chemistry during the cold months. Follow these top five steps to ensure your in-ground pool stays in peak condition all winter long.

1. Clean the Pool Thoroughly

Start by skimming all surface debris, brushing the walls, and vacuuming the pool floor completely. Removing organic leaves and dirt before covering prevents stubborn surface stains on vinyl liners or fiberglass finishes and starves off potential algae growth.

2. Balance Your Water Chemistry

Test and adjust your pH, total alkalinity, and calcium hardness levels several days before shutdown. Adding a specialized winter chemical kit with shock treatment and algaecide keeps the water clear, balanced, and free of bio-growth throughout the winter.

3. Lower the Water Level

Lowering the water height stops freeze expansion from cracking skimmers and tile lines. Vinyl liner pools need the water level dropped just below the skimmer mouth, while fiberglass pools require specific water management to balance ground pressure safely.

4. Drain and Blow Out Equipment

Remove all drain plugs from pumps, filters, and heaters so trapped water cannot freeze and crack equipment housings. Use a high-volume blower to clear all underground plumbing lines, then seal return jets and skimmers with heavy-duty winterizing plugs.

5. Install a Secure Safety Cover

Anchor a heavy-duty, properly fitted safety cover tightly across the entire pool surface. A durable cover keeps out autumn debris and animals while safely supporting heavy winter snow and ice loads until spring arrives.
