Pool Liner FAQ

A pool liner is an essential part of any swimming pool. Your liner will be the barrier between your pool water and the underlying concrete base of your pool, helping minimize the water leaking out of the pool into the ground. It will help prevent damage to the base of your pool, provide your pool with a smooth surface, and give your pool a clean and pleasing appearance. Whether you’re installing a new liner for the first time or upgrading to a new style to build yourself “the perfect pool” it’s essential that you have a good understanding of how to fill it with water appropriately.

How do you find a hole in a pool liner?

It is easier to find a hole in your pool liner when the pool does not have any water in it. Before you fill your pool with water, you should always check the entire surface for any signs of rips or tears. Use a flashlight and do a thorough visual check of the frequently trafficked areas of your pool. It is possible to find a hole with water in the pool if you have an idea of where the hole may be located and with a set of snorkeling gear. If the hole is in the deep end of the pool, you will likely need scuba diving equipment, or hire the help of a professional to identify and repair the hole. Once you have identified the hole, you will need to use a pool liner repair kit or hire a professional to patch the hole.

How much does a new pool liner cost?

The cost of a pool liner will vary depending on the size and style that you choose, but most liners range between $400 and $1,000 depending on whether you purchase a pre-made or custom-fit product. A vinyl liner will generally cost less than a chlorine resistant one but will require more regular upkeep to keep it looking its best.

Can you put a liner in a concrete pool?

One of the primary benefits of using a pool liner is that it’s easier to install than fiberglass or concrete pools. You will not have to worry about finding rebar or hiring contractors to pour a new base, eliminating the risk of costly mistakes, delays, and additional expenses.

How long does a pool liner last?

Most pool liners can last for up to 10 years, provided that you take good care of your new swimming pool. They are designed to withstand essential wear and tear, but they will eventually disintegrate due to UV rays, contaminants in the pool, and concrete wear.

How much does it cost to replace a pool liner?

The cost of replacing your swimming pool liner depends on the size and type but usually ranges between $800 and $3,000 per liner. Most liners will be covered by warranty at the purchase, so you may not need to worry about replacing them as often as you would with other materials.

How do you clean a pool liner?

Regular cleaning of your pool liner will help it last longer. You can brush or vacuum the liner manually or use a pool robot, this will help keep most day-to-day debris and algae off your liner. If you notice any significant build up (they will often appear as dark spots), you can wipe it down by hand with a clean cloth or use an alkaline or bleach-based cleaner for more significant stains.

On top of these cleaning methods, you can help maintain your liner and keep it clean by using a pool cover to keep out unnecessary debris and dirt. Also, keeping your pool chemicals balanced will help maintain your liner as well.
