When to Replace a Vinyl Pool Liner (and What the Job Involves)

A vinyl liner is the skin that holds your pool's water, and like any skin it ages. Sun, chemicals, heat, and years of swimmers all take their toll. The question isn't whether a liner will need replacing. It's when, and whether you catch it on your own terms. Traditional liners generally last 10 to 15 years, so if yours is getting there, here is how to read the signs and what happens when it's time.

Signs the liner is wearing out

Fading is the most obvious. A pattern that has gone pale, especially near the waterline and on the steps, shows a liner that is aging. On its own, fading is cosmetic. Combined with the other signs below, it's a warning.

Then look at the feel and the fit. A liner that has stretched will show wrinkles, especially on the floor and along the walls. One that has gone brittle may crack at corners or tear around the skimmer, the return fittings, and the steps. Stains that won't brush out, thin spots, and places where the liner has pulled away from the wall are all worth noting. If you can see a seam opening or a small tear, don't wait.

Water loss is the sign most people miss. Some water leaves every pool through evaporation, and Alabama heat speeds that up. If you are adding water far more often than the weather explains, a leak could be the cause, and the liner is one of the places to look. Water escaping behind a wall can cause its own damage, so a slow leak is worth chasing.

Repair or replace?

A small tear can sometimes be patched, and a patch buys time. But if the liner is faded, stretched, brittle, and patched in several places, you are putting money into something near the end of its life. As a rule of thumb, when problems show up in more than one spot, or the liner is past the 10 to 15 year mark, replacement is usually the sounder move. A technician can look at it and give you an honest read.

What the replacement involves

It's a bigger job than most owners expect, but it's a well-defined one. Mr. Pool breaks it into four steps:

• Prep: the pool is drained and the old liner is removed.
• Correct: the steps are acid-washed, imperfections in the bottom are fixed, and wall foam goes in if it is needed.
• Develop: the new Findlay liner is installed, along with the skimmer, gasket, and return plates, plus a drain cover.
• Finish: the liner is given time to settle, the pool is refilled, and the water-holding is tested.

The Correct step is where a good job separates from a rushed one. A new liner follows whatever is underneath it, so a rough bottom or a pitted step shows through. Fixing those first is what gives the new liner a smooth, tight fit.

What to do while you wait

If you suspect the liner is failing, resist the urge to drain the pool and see what is underneath. A pool emptied without a plan can cause new problems, and the old liner is still holding your walls in position until the crew arrives. Keep the water balanced and the baskets clear, note where you see wrinkles, fading, or leaks, and take a few photos. That information helps the technician understand what happened and what to look for on site.

Choosing a liner

Mr. Pool installs Findlay liners, made of virgin vinyl in the United States and built to resist UV. They come in light and dark colors and in regular and swirl patterns, and they are available for rectangular, oval, and round pools. Findlay backs them with a two-year full replacement on manufacturer defects and a 20-year prorated warranty.

Once the new liner is in, a few habits help it last. Keep the water balanced, since water that runs too harsh in either direction ages vinyl faster. Keep sharp objects, rough toys, and pool furniture away from the walls and floor. Watch the water level so the liner stays supported. Brush gently, use a vacuum head made for vinyl, and test the water weekly. Those are the same habits that make a pool easier to care for in general.

Color and pattern change how the water looks, so ask to see the options before you decide. Liner replacement is available around Montgomery, Tuscaloosa, Dothan, Enterprise, and Auburn/Opelika. If your liner is showing its age, call Mr. Pool at (334) 271-7665 to talk through a replacement.
