When a Liner Is Done
A vinyl liner is the surface of your pool, and it has a service life. Most in-ground liners last 7–12 years. Above-ground liners last 5–9. Sun, chemicals, and the simple act of the vinyl stretching and relaxing every season wear it out. Spring is when most owners find out theirs has reached the end, because the pool comes out of winter with a problem that wasn't there in October.
Signs the liner needs replacing, not patching:
- Fading and brittleness. The color is washed out above the waterline and the vinyl cracks when you press on it.
- Multiple leaks or a leak you can't find. One tear is a patch. Three tears, or a slow loss with no visible hole, means the vinyl is failing everywhere.
- Wrinkles that won't smooth out. The liner has stretched and lost its fit.
- The bead keeps pulling out of the track. Shrunken vinyl can't hold tension.
- Stains that won't come off. Mineral and algae staining that's gone into the vinyl.
If it's 10 years old and showing two of these, plan the replacement. If it's 4 years old and has one tear, patch it.
Pool Liner Replacement Cost
Liner pricing has three parts: the liner itself, the labor to measure, remove, and install it, and the water to refill the pool.
| Pool Type | Liner Cost | Installed Total (2026) |
|---|---|---|
| Above-ground, 24 ft round | $300–$800 | $800–$2,000 |
| Above-ground, oval or large | $400–$1,000 | $1,000–$2,500 |
| In-ground, 16x32 rectangle | $1,200–$2,500 | $3,000–$5,000 |
| In-ground, 20x40 or freeform | $1,800–$3,500 | $4,000–$7,000 |
| In-ground with steps, benches, or safety ledge | add $300–$1,000 | $4,500–$8,000 |
Add-ons that move the number:
| Add-On | Typical Cost |
|---|---|
| Water to refill | $100–$600 depending on size and whether you truck it in |
| New foam wall and floor padding | $300–$800 |
| Replacing damaged floor base (vermiculite or sand) | $500–$2,000 |
| New faceplates, gaskets, and light ring | $100–$300 |
| Removing and hauling the old liner | $100–$300 |
| Thicker gauge upgrade (20 mil to 27 or 28 mil) | $200–$600 |
A quote that's far below these ranges usually means a thin liner, no new gaskets, and no floor work. Those jobs leak early.
Which Thickness
Liner thickness is measured in mil (thousandths of an inch) or gauge. Standard in-ground liners are 20 mil; heavier ones run 27–30 mil. Thicker vinyl resists punctures and lasts longer but costs more and is harder to fit around tight corners. For most in-ground pools a 27 mil wall with a 20 mil floor is the sweet spot. For above-ground pools, the thickest the manufacturer allows for your wall is the right call, because the wall is what takes the abuse.
How to Hire a Liner Installer
Liner work is measurement work. A liner cut an inch wrong wrinkles for the rest of its life. Here's how to screen:
- 1Ask how they measure. The good ones take dozens of measurements and send them to the manufacturer; some use a laser measuring system. A tape measure and a guess is not enough.
- 2Ask for the liner brand and mil thickness in writing. Along with the warranty, which is usually pro-rated and covers seams, not sun damage.
- 3Ask what's included. Gaskets, faceplates, floor repair, water, and old-liner removal should each be a line item.
- 4Ask about timing. Spring is the busy season; a liner ordered in April may not be installed until late May. Custom in-ground liners take two to four weeks to manufacture.
- 5Verify the license. Every listing on Pool Service Scout links to your state's lookup. Liner work on an in-ground pool is contractor work in most states.
- 6Read reviews for the word "wrinkles." It's the most common liner complaint and it comes down to measurement and installation skill.
Above-ground liners are a reasonable DIY job for a handy owner with a helper and a shop vac. In-ground liners are not; the measurement, the vacuum-fit, and the step and corner work are what you're paying for.

Make the New One Last
- Keep the water balanced; low pH and high chlorine age vinyl fast
- Never let the water level drop below the skimmer for long, or the liner can shrink and pull out of the track
- Use a cover in the off-season
- Keep sharp toys and metal furniture out of the pool

Bottom Line
Budget $3,000–$7,000 for an in-ground liner and $800–$2,500 for above-ground, and hire on measurement skill, not the lowest number. Find a pool liner installer near you and get the brand, thickness, and inclusions in writing.
