Winterizing Your Pool the Right Way: 5 Common Mistakes to Avoid

Closing your pool for winter is about more than just putting on a cover and hoping for the best. It’s a critical part of home and pool ownership that protects your investment, prevents costly repairs, and, most importantly, keeps your backyard safe throughout the colder months.

But while many pool owners think they’ve done enough, small oversights can lead to big problems. From safety gaps to equipment damage, winterizing your pool incorrectly can be a costly mistake. Below are five of the most common errors and how to avoid them.

1. Skipping a Thorough Pre-Close Cleaning

Mistake: Draining or covering a pool without properly cleaning it first.

Why it matters: Leaves, algae, and debris left behind can break down over winter, staining pool surfaces and making spring opening a mess.

What to do instead:

  • Skim out leaves and debris.
  • Brush the walls and floor thoroughly.
  • Vacuum the pool to remove fine particles.
  • Balance pH, alkalinity, and calcium hardness to prevent corrosion or scale buildup.

Cleaning before closing also gives you a chance to inspect your safety equipment, especially pool fences and gates, for wear or rust.

2. Using a Damaged or Poorly-Fitted Pool Cover

Mistake: Relying on an old or ill-fitting pool cover for winter protection.

Why it matters: A weak or sagging cover can collect debris, collapse under snow, or even create drowning hazards.

How to fix it:

  • Invest in a durable, properly-sized mesh pool cover that’s designed for winter weather.
  • Mesh covers from All‑Safe allow rainwater to pass through while blocking leaves and debris, so they’re ideal for seasonal safety.
  • Use secure anchors and regularly inspect the tension to prevent sagging.

Mesh pool covers also prevent the need for heavy pumps and reduce the risk of standing water, an essential safety feature during the off-season.

3. Ignoring Fence and Gate Security

Mistake: Assuming your pool fence doesn’t matter when the pool is closed.

Why it matters: Winter doesn’t eliminate risk. In fact, with less supervision and slippery conditions, fences and gates are even more critical.

What to check before winter:

  • Ensure your mesh pool fence is securely fastened, with no sagging or gaps.
  • Test your gate latch and self-closing mechanism, especially if temperatures could affect spring tension.
  • Replace worn or rusted hardware and posts before they weaken further over winter.

Pro tip: All-Safe offers replacement fence parts, gate latches, and posts designed for long-term durability, even in harsh climates.

4. Failing to Drain and Store Equipment Properly

Mistake: Leaving pool equipment or accessories exposed to the elements.

Why it matters: Water expands when frozen, leading to cracked pipes, damaged filters, and broken fittings.

What to do instead:

  • Drain all pumps, filters, heaters, and chlorinators.
  • Store accessories (skimmers, floats, ladders) in a dry area.
  • Detach and clean pool safety nets before storing them for the season.

If you plan to leave your mesh fence or cover installed, double-check installation points to ensure stability through wind and frost.

5. Overlooking Safety Reminders for Guests and Kids

Mistake: Assuming everyone knows the pool is “off limits” during winter.

Why it matters: Curious kids and pets can still wander near the pool area, especially if covers are mistaken for solid surfaces.

Safety solutions:

  • Post signs or visual cues indicating the pool is closed.
  • Use alarms or motion detectors as an added layer of safety.
  • Make sure fencing meets code and doesn’t leave access points open due to snow piles or shifting soil.

A properly secured pool area, even when not in use, sends a clear message: safety comes first.

Color Variations

Colors on your screen or brochure may not match the actual color of your product.

Due to the many variations in monitors, phones, and browsers, color samples and product examples may appear different on different screens. Computers and mobile devices are not all calibrated equally and color reproduction on the Internet is not precise. The same is true for printed items such as brochures and other sales literature. 

In addition, the colors of our products photograph differently under different lighting conditions. For example, photos taken in full sunlight will vary from photos taken on a cloudy or overcast day. Similarly, shadows from nearby objects can affect the color and transparency of our products. If a precise color or specific shade is important, please inspect the actual color of your product prior to installation.

Colors will vary from batch to batch.

Many of our products’ materials are not available through typical stores and vendors and therefore must be custom manufactured specifically for our use. In order to control costs and provide you with the best value possible, our raw materials are produced in large batches and can often take several months to receive. The colors of our materials can, and often do, vary slightly from batch to batch. Although we make every effort to minimize color variations, we cannot be responsible for these differences when they occur. If a precise color or specific shade is important, please inspect the actual color of your product prior to installation.

Color names are subjective and may not be what you think the color should be.

For example, we use the name “putty” to describe some of our products. Your idea of the color “putty” may be different than someone else’s idea of “putty”. In addition, products may have the same color name but may not be the exact same color. For example, we have different shades of “black”. Please do not order using color names as your only guide. If a precise color or specific shade is important, please inspect the actual color of your product prior to installation.

Inspect the actual color of your product prior to installation.

If it is important that your product be an exact color or shade, it is highly recommended that you inspect the actual product prior to its installation and address any concerns with your local independent installer. Most independent installers do not offer refunds or accept returns due to color variations.
