How To Close In-Ground Swimming Pool?

How To Close In-Ground Swimming Pool

During the warm months, in-ground swimming pools are a wonderful addition to any backyard, offering hours of entertainment and relaxation. To ensure that your pool is prepared for the upcoming swimming season, it’s crucial to properly close it up at the end of the summer. Although closing an in-ground pool can seem difficult, it is manageable with a little planning and the right procedures.

Preparation is Key

There are a few key preparations that must be made before you can start the process of closing your pool. The first step is to clear the pool of all trash, including leaves, insects, and other trash that may have gathered throughout the summer. Additionally, you should lower the pool’s water level, ideally to about 6 inches below the skimmer. This is to make sure that when the pool cover is installed, it won’t become too heavy and cause damage.

Additionally, you should take out any floating pool accessories like rafts, loungers, and pool floats. These objects, which are frequently made of foam or plastic and have the ability to absorb water, could weigh down the pool cover if they become heavy. In addition, it’s a good idea to remove any furniture around the pool that isn’t intended for outdoor use and store it until the following swimming season.

The chemistry of the water is balanced as a further critical step in the preparation process. The water in your pool needs to be chemically balanced properly to be safe for swimming and to prevent damage to the pool itself. Between 7.2 and 7.8 should be the pH, between 80 and 120 should be the total alkalinity, and between 1 and 3 should be the chlorine level. To remove any remaining bacteria or algae, you should also shock the pool with chlorine.

Closing the Pool

It’s time to close the pool once you’ve finished the preparations. Installing a pool cover is the first step in pool closure. Make sure to select the pool cover that best suits your needs from the range of options available, including solid and mesh covers. While mesh covers are best for regions with mild winters because they allow water to pass through while keeping debris out of the pool, solid covers are best for regions that experience heavy snowfall because they offer the best protection against the elements.

To ensure that the cover stays in place throughout the winter, it is crucial to properly secure it after installation. Water bags or plastic cover clips should be used to secure the pool cover. To keep the pool cover in place, water bags are filled with water and placed on top of the cover. To keep the pool cover firmly in place, plastic cover clips are put around the edge of the cover and attached to the pool deck.

Winterizing the plumbing and equipment is a crucial step in closing the pool. This entails disconnecting any hoses, shutting off the pump and filter, and draining the pool’s water supply. By removing any furniture and covering any outdoor electrical outlets, you should also winterize the pool deck.
Additionally, take out any pool skimmer baskets and store them somewhere dry. It’s also advised to take any pool ladders or handrails off and store them somewhere dry. By doing so, they will avoid winter damage and there will be less chance that the pool cover will get harmed.


Your pool needs ongoing maintenance throughout the winter months in addition to a one-time closure. Regularly inspect the pool cover for any rips or tears and make sure it’s still securely fastened. To make sure that the chemical levels in the pool are balanced, you should also check them. Additionally, it’s critical to perform routine maintenance on the machinery, including filter cleaning and leak detection. By performing these routine inspections, you can make sure that your pool is weatherproof and prepared for use when the swimming season resumes.

Observing the weather is a crucial component of pool maintenance during the winter. To keep the snow from building up and damaging the pool cover after a significant snowfall, it’s crucial to remove it. Additionally, it’s crucial to make sure the pool cover is still firmly in place and that no water is leaking into the pool during periods of heavy rain or flooding.

Following the manufacturer’s instructions is one of the most crucial things to keep in mind when closing your pool. The requirements for closing and maintenance will vary depending on how each pool is unique. It is possible to make sure that your pool is properly shut down and prepared for the upcoming swimming season by adhering to the manufacturer’s instructions.


In conclusion, while closing an in-ground pool may seem difficult, it is actually quite simple if the proper planning and procedures are followed. You can make sure that your pool is prepared for the upcoming swimming season by clearing out debris, balancing chemicals, and securely fastening the pool cover. Keep in mind to adhere to the manufacturer’s guidelines and, if necessary, seek professional advice.

In addition to providing you and your family with a safe and enjoyable swimming experience, a well-maintained pool increases the value of your home. Additionally, a properly closed pool will give you peace of mind because you’ll know that your pool is safe during the off-season and that you can reopen it without any problems the following season.
