When Should You Replace Your In-Ground Pool Liner?

While most in-ground pool liners can last up to 12 years, eventually time, pool chemicals and weather will cause damage to your liner, requiring it to be replaced. It’s important to replace your liner as needed because it acts as a critical barrier between the water and the structure of your pool.

But how do you know if your liner needs to be replaced? Here are a few signs that it might be time.

Is it time to replace your in-ground pool liner?


Sun exposure over time can cause your liner to become brittle, which makes it more susceptible to leaks, punctures and rips. If you notice significant fading, it may be time for a replacement.


Wrinkles in your liner can be a result of water chemistry issues or slipping/stretching that causes the liner to sag. Regardless of the cause of a wrinkled liner, this is a sign that your liner is liable to tear. It’s important to remember that wrinkled liners cannot be repaired; replacement is required.


Small cracks and tears in your liner can lead to water loss and further deterioration to the liner. Some cracks are so small that they can be hard to detect. If you start to see signs of deterioration on your liner, monitor your water level over the course of a week to determine if you’re losing water. If you experience more than an inch of water loss during that time, it is an indicator that you have a leak.

Losing water:

If you notice water loss beyond normal evaporation and splashing, there may be a tear in your liner. Some tears can be repaired with a wet patch kit, however, large or multiple tears will require a full liner replacement.
