How Long Should a Swimming Pool Liner Last? Vinyl liners for in-ground pools tend to last 8 to 12 years, on average, although some might require replacement after just 5 years and others will make it to 15 or 20. For above-ground pools, which are more exposed, plan on 6 to 10 years.
Leaks in a vinyl liner can cause a host of problems. If leaking during winter, and your pool is closed and covered, the pool cover can be damaged or be pulled into the pool. If not refilled, and the water level goes too low, the vinyl liner can pull away from the pool, causing wrinkles.
