What’s the Average Lifespan of an Aboveground Pool Liner?

Your aboveground pool’s liner is one of the most expensive parts of its structure. While no liner will last forever, it makes sense to do whatever you can to get more use out of yours before a replacement is needed. Keep reading to learn more about the factors that damage a pool’s lining and how you can preserve yours with a few simple adjustments.

What’s the Typical Lifespan of an Aboveground Pool Liner?

Most aboveground pool liners last 5 to 10 years in normal conditions. How long yours will last depends on a variety of factors, including:

• The shape of your pool. Pools with lots of corners have liners with more seams than a standard round or oval pool liner, making them more likely to develop problems in those areas.
• The pool chemicals you use. Using chemicals that are too harsh or that make your pool water too acidic can damage your pool liner.
• The amount of sun exposure your liner receives. Most pool liners are made from fade-resistant vinyl, but the sun’s UV rays can still warp the plastic and cause it to become
• Whether your liner sustains damage. Pool liners that get exposed to lots of sharp ice and debris may become scratched, stretched, or torn before their time.

How to Make Your Liner Last Longer

Hoping to keep your liner around a little longer? Follow these tips to make it happen.

• Invest in a quality liner. Quality liners made from durable materials last longer than cheaper liners that are not as well-made. They’re more resistant to fading and stretching and are harder to tear.
• Monitor your pool’s pH levels carefully. If your pool water becomes too acidic, it’ll start to eat away at your liner’s vinyl.
• Mix your pool chemicals into a bucket of water before adding that water to your pool. This will make sure they dissolve properly instead of settling on the bottom of your pool and damaging the liner.
• Don’t let your pool’s water level dip too low. If your pool loses too much water, your liner won’t have as much pressure on it and may begin to shrink or sag.
• Put a sturdy winter cover over your pool during the off-season. The cover will protect your liner from the ice and debris that accumulate on the surface of your pool over the winter.

Good Care Keeps Your Liner Going

Your pool’s liner won’t last forever, but taking care of it will significantly extend its life. Don’t let yourself get careless about proper pool maintenance and closing procedures and you won’t have to replace your liner for many years to come.
