Pool closing costs $250 to $500 for inground pools and $150 to $300 for above-ground pools on average. Closing (or winterizing) a swimming pool is a service done by professionals to make sure none of the pool components are damaged by freezing temperatures in the winter.

Closing a pool means preparing a swimming pool and the related equipment for wintertime and freezing temperatures. This involves a deep cleaning, lowering the water level slightly, adding chemicals, and draining plumbing.

If you live in an area that's warm all year, you may only need to cover your pool when you're not using it. If you live in a colder climate, you should close your pool when temperatures drop below 65 degrees and before they hit freezing levels.

The best time to close your pool for the winter is in September or October, or whenever the temperatures regularly drop below 65 degrees Fahrenheit. In the warmest parts of the U.S. like Florida or California, you can usually keep your pool open year-round.

Your water level should be 3 to 6 inches below the skimmer during winterizing. This means removing about 12 inches of water from the pool each year and then filling it back in after the winter months.

Closing a pool takes around 2 hours on average, depending on the pool type and size. Above-ground pools typically take less time than inground pools or those with added features like inground hot tubs. Custom-fitted pool covers are harder to install and may take longer.

Yes, it's important to clean your pool before or during the closing process. Removing any leaves, bugs, or debris helps prevent algae growth and long-term staining. Make sure to skim debris off the top of the water, vacuum, and brush the bottom and sides of the pool.
