As winter sets in, pool owners across the country face a common challenge: protecting their pool covers and liners from the harsh effects of ice and snow. At Pools Plus More, we understand how important it is to keep your pool investment safe during the colder months. With the right strategies and a little preparation, you can prevent costly damage and ensure your pool is ready for a smooth opening in the spring.
Why Ice and Snow Are Dangerous for Pool Covers & Liners
When temperatures drop, ice and snow can wreak havoc on your pool’s structure. Water expands as it freezes, and this expansion can cause cracks in pool liners, walls, and even the cover itself. If snow accumulates on a cover, the added weight can lead to sagging, tears, or even collapse—especially if the cover isn’t properly secured or maintained.
Without a proper winter cover, your pool is vulnerable to:
-
Liner tears and wall cracks
-
Equipment failure due to freezing water
-
Debris buildup and algae growth
-
Increased spring cleaning and repair costs
Choosing the Right Winter Pool Cover
Not all covers are created equal. The best winter pool cover for your needs depends on your climate, pool type, and how much snow and ice you typically experience.
-
Solid Covers: Block sunlight and debris, but require regular pumping to remove standing water.
-
Mesh Covers: Allow water to drain through, reducing the risk of water accumulation and cover collapse.
-
Hybrid & Safety Covers: Offer the highest level of protection and can support the weight of people or pets.
Regardless of the type, always choose a cover with strong stitching, UV resistance, and a snug fit to maximize protection.
Tips to Protect Your Pool Cover & Liner
-
Install the Cover Properly
Clean and balance your pool water before closing. Lower the water level as recommended, remove ladders and accessories, and center the cover over your pool. Secure it tightly with water bags or cover clips—never use cement blocks or water bottles, as these can void warranties.
-
Use Pool Cover Air Pillows
Air pillows help redistribute pressure from ice expansion and keep the cover lifted, making it easier for snow and water to slide off.
-
Keep the Cover Clear of Snow & Ice
Use a soft broom or brush to gently remove snow. Avoid sharp tools that could puncture the cover. If you live in a heavy snow area, consider a mesh cover to reduce water buildup.
-
Add a Pool Cover Sealant
Applying a sealant before winter can create a protective barrier, making it easier to remove snow and ice and reducing the risk of damage.
-
Monitor Water Levels
Keep water levels within 12 inches of the wall and use a winter cover pump to remove excess water. This prevents the cover from collapsing and reduces stress on the liner.
-
Address Small Tears Promptly
Patch any small tears or holes as soon as you notice them. This prevents further damage and extends the life of your cover.
Additional Winterizing Steps
-
Pad sharp edges and decking before installation.
-
Maintain chlorine levels below 3.0 ppm when closing the pool.
-
Shock the pool, adjust pH, and add algaecide to prevent algae growth.
-
Use a winter enzyme treatment to break down organic contaminants.
Why a Winter Cover Is Essential
A winter pool cover is your first line of defense against the elements. It protects your pool’s structure, maintains water quality, and enhances safety for children and pets. While a cover is crucial, it’s just one part of a comprehensive winterizing approach. Don’t forget to take additional steps like chemical treatment and equipment protection.
