How to Replace a Pool Liner

Swimming-pool liners are not meant to last forever. Even if you take care of your liner and maintain it properly, it can eventually tear or get holes in it. The sun can shrink the liner, and over time it can thin out. Pool liners can vary in price depending on the size of your pool, and if you want your liner to be patterned rather than plain blue, you should know that patterns range from a more modest boulder or tile print to a more eccentric aquarium print, complete with fish. Whatever type of pool liner you prefer, replacing your old one can be a pretty big job. You can do this yourself (with a handful of friends), but if you aren't really sure about what you're doing, it may be best to leave the matter to a professional pool-liner replacement company. They have the tools, know-how, and people required to replace the liner. See below for instructions on how to do the job yourself.

Tools and Materials Needed for the Job:

  • New pool liner
  • Ladder
  • Screwdriver (or power drill)
  • Rake
  • Sand
  • Nut driver
  • Utility knife
  • Several helping hands
  • Submersible pump
  • Hose


  1. You need to remove the old liner first. Begin by emptying out the water from your pool. Use a submersible pump and hose to empty the water. Be sure to point the hose away from your house.
  2. Next, you need to take off the hoses attached to the filter and the return.
  3. Once you have the pool empty and the hoses removed, you need to take out the old liner. Start taking the rails off using a power drill and set them aside. Then remove the long plastic clips at the top of the walls. 
  4. Next, use a utility knife to begin cutting the old liner. The liner will be quite heavy, so it will need to be removed in pieces.
  5. Once you have the old liner removed, use a rake to rake around the sand below. If need be, add more sand and rake it level.
  6. Begin unfolding the new liner (this is when you'll need helpers), and start pulling it over the walls, being careful when stretching it so it doesn't tear. Have your helpers hold the liner in place while you begin putting water into the liner. 
  7. Start putting the plastic clips back in place and the rails back on while the helpers move their feet around inside the pool to smooth out wrinkles.
  8. Continue filling the pool up with water while replacing the filter and return hoses.

Replacing a pool liner takes quite a bit of work and needs more than one person to do the job. If you aren't up for the job, contact a pool-liner replacement company such as Pettis Pools & Patio for help.
