With balanced water chemistry and routine care, a pool liner can last an average of 15 to 20 years. Consistent upkeep prevents damage from excess chlorine, sanitizer, and heavy-metal buildup. Periodic professional inspections add an extra layer of protection, helping the liner stay watertight and attractive for its full lifespan.
Patching works for small, isolated tears or leaks and can buy several more seasons of use. Once the vinyl shows widespread brittleness, fading, or seam failure, replacement becomes the smarter long-term move because patches won’t restore strength or watertightness. A pro can confirm whether a repair will hold or if a new liner will save money down the road.
A pool liner replacement project takes one to four days to complete when executed properly. This duration covers draining the pool, removing the old liner, installing the new liner, and refilling the pool. Factors such as pool design, square footage, and weather conditions influence the total time, yet professional installers ensure that the job is finished efficiently.
