The Importance of Properly Closing Down Your Pool

The Importance of Properly Closing Down Your Pool

Owning a pool means months of summer fun, but it also comes with seasonal responsibilities. One of the most crucial is closing down a pool correctly before winter arrives. Whether you call it shutting down a pool for the winter, or closing a swimming pool for the season, the process directly affects the health of your pool and the cost of maintaining it next year.

At Anomaly Pool Services, we specialize in everything from closing a salt water pool to complete pool opening and closing services. Below, we’ll walk you through why proper pool closure matters, the best time to close a pool for winter, and what you can expect from a professional service.

Why Closing Down a Pool Matters More Than You Think

A pool is an investment, one that can last for decades if cared for properly. When you're closing down a pool for winter, you’re essentially preparing it to withstand freezing temperatures, debris, and months of inactivity. A rushed or poorly performed closing can lead to:

  • Cracked pipes
  • Damaged filters or pumps
  • Algae growth
  • Stained liners and cloudy water
  • Costly repairs in spring

A proper swimming pool closing service from experts like Anomaly Pool Services protects your pool’s structure, equipment, and water quality so you can enjoy an easier, faster, and cheaper opening when warm weather returns.

When to Close Pool for Winter: Timing Is Everything

One of the biggest questions pool owners ask is, “When is the best time to close a pool for winter?”

Here’s the general rule:

Close your pool when the water temperature consistently stays below 60°F (15°C).

Why? Because algae stops growing below this temperature. If you close too early, you trap warm water that becomes a perfect breeding ground for algae. If you close too late, you risk freezing damage.

Depending on where you live, the best time to close pool for winter is usually:

  • Late September to October in cooler climates
  • October to early November in moderate climates

If you’re unsure, Anomaly Pool Services can evaluate your pool and local weather conditions to determine the perfect swimming pool closing time for your area.

The Complete Process of Closing Down a Pool for Winter

Many homeowners attempt closing their pool themselves, only to realize how many steps are involved. A correct winter shutdown includes far more than just covering the water.

Here’s what the professionals at Anomaly Pool Services do to ensure your pool is protected all season long:

Deep Cleaning the Pool

Before any chemicals or covers are added, the pool must be spotless. A pool cleaning professional will vacuum dirt, skim debris, brush walls, and clean filters. A neglected interior can cause algae blooms even after the pool is covered.

Balancing the Water Chemistry

Before closing a swimming pool for the season, the water must be perfectly balanced. This includes:

  • pH
  • Alkalinity
  • Calcium hardness
  • Stabilizer levels

Proper balance prevents stains, scale buildup, and corrosion during winter.

Adding Winterizing Chemicals

A winter chemical kit may include algaecide, chlorine shock, and anti-freeze solutions (for certain types of pools). These help prevent contamination over the winter months.

Lowering the Water Level

Depending on the pool and cover type, the water level is lowered to a safe height. This keeps skimmers and tile lines from cracking if water freezes.

Draining and Storing Equipment

Professionals drain pumps, heaters, filters, and plumbing lines to prevent freezing. This step is often where DIY efforts go wrong, you must blow out the lines fully or risk severe pipe damage.

Securing the Pool Cover

A strong, properly fitted winter cover protects your pool from leaves, animals, and heavy snow. Anomaly Pool Services ensures every cover is installed tight, secure, and safe.

Closing a Salt Water Pool vs. Standard Pools

If you own a saltwater pool, you may wonder whether closing a salt water pool requires special steps. The answer: yes, but an expert can handle it easily.

Saltwater generators must be cleaned, inspected, and stored carefully so the cell doesn’t corrode during the winter months. Anomaly Pool Services provides full maintenance for salt systems, ensuring they last longer and work more efficiently next season.

Why Choose a Professional Pool Closing Service?

While some homeowners try to manage their own closing swimming pool for winter, hiring an expert saves time, prevents mistakes, and extends the life of your pool.

Benefits of a Professional Closing Include:

  • Proper winter prep for pumps, filters, and lines
  • Accurate chemical balancing
  • Freeze protection for equipment
