Pool liner replacement costs $2,000 to $5,000 for an average above-ground pool or $3,000 to $7,000 for an in-ground pool liner. These price ranges include the total job cost for the new liner, pool draining, removing the old liner, minor prep to the pool base, and liner installation.
The biggest signal that you need to replace a pool liner is when you find water leaking out of the pool. Still, there are many other important signs that indicate your liner is wearing out, so call a swimming pool company if you see these problems:
The size and shape of your pool will determine how long it takes to replace the liner.
For example, consider these common scenarios:
You can expect most pool liners to last for 5 to 15 years or more if you've maintained the pool regularly. Keeping balanced pH levels in the water, checking the pool pump frequently, and changing pool filters as recommended will extend the lifespan of all parts of your pool.
Get a thicker liner since they can outlast thinner ones by several years.
Most swimming pool companies will advise you against putting a new pool liner over the old one since a liner is stronger when adhered directly to the pool base. Air pockets underneath the old liner especially make it impossible to cover it with a new liner.
However, sometimes you can leave an old liner in place if the pool bottom is sand and most of the old liner is in good condition. Talk to a contractor about your options if you have a pool like this to confirm the longevity of the new liner.
Patching a pool liner is worth it to save money on a full pool-liner replacement if you've had the liner for less than 5 years and the only damage is a minor tear. A professional wearing a dive tank can patch the liner underwater without even draining the pool.
Pool liners that are 5 to 10 years old, have large rips, or have started separating from the pool walls will typically need replacing.
