Common Questions:

Why should I use a winter pool cover?
  • It protects your pool from debris, algae growth, and damage caused by freezing temperatures. It also reduces maintenance and chemical costs during the off-season.
How do I install a winter pool cover?
  • Use water bags, cover clips, or a cable-and-winch system depending on your pool type. Ensure the cover is tight and secure to prevent sagging or wind damage.
Do I need to lower the water level before covering the pool?
  • Yes, typically 4 - 6 inches below the skimmer for above-ground pools and 12 - 18 inches for in-ground pools, depending on your cover type.
Should I add chemicals before closing the pool?
  • Definitely. A winterizing chemical kit helps prevent algae, staining, and scaling during the off-season.
How do I prevent water from pooling on the cover?
  • Use a cover pump or air pillow to keep the surface elevated and drain excess water.
How do I clean my winter pool cover?
  • Rinse with a hose and mild soap. Let it dry completely before folding and storing to prevent mold and mildew.
Can I walk on a winter pool cover?
  • Only safety covers are designed to support weight. Standard covers can tear or collapse under pressure.
Will a winter cover protect my pool from freezing?
  • It helps reduce freezing damage but won’t prevent it entirely. Use winterizing accessories like air pillows and antifreeze in plumbing lines.
