In order to replace a pool liner in some cases the pool railings must first be removed in order to access the liner. The skimmer and return jets must both be removed from the pool wall in order to replace the lining. The watertight gaskets installed on both sides of the skimmer and pool jets must be replaced as well during the job. The liner is then evenly laid out across the pool surface and attached to the pool wall. The liner installation method will vary based on the liner type.
There are three liner types that will all vary in price depending on how big the pool is, whether the lining has a visual design and the type of liner you choose. Liners with a design embedded into the lining are sometimes more than double the cost of a plain, light blue liner. Overlap liners are the most cost-effective. These liners overlap the pool wall and are held in place with coping strips placed along the top of the pool wall. A beaded liner replacement is easier to install but costs more money for the liner itself. The beaded liner snaps into a bead receiver installed along the inner sidewall of the pool. Replacing these liners is easier than an overlap liner, and they do not hang over the pool wall.
The beaded liner may cost more money than an overlap liner, but if the bead receiver is already installed from a previous liner, the labor costs will be a lot cheaper. The beaded liner is accessible without removing the pool railings. This will save a lot of time during installation, which equals cost savings. The overlap liner, on the other hand, must have the pool railings removed for access to the top of the pool wall where the coping strips are.
Liners come mostly in two sizes of thickness. Most overlap liners come manufactured as a 20-gauge liner, making it the more popular gauge. Some other pool liners will be sold in a 25-gauge vinyl, which is thicker and often more durable. Most beaded liners are sold in 25-gauge materials, and most overlap liners come in the 20-gauge vinyl. This is another factor to consider in the price of a liner. The biggest factor in price, however, will be the size of the pool. The bigger the pool is, the more expensive the liner and labor costs associated with installation will be.
