According to the Association of Pool and Spa Professionals (APSP), there are approximately 30,900 public and 10.4 million residential swimming pools in the US. The abundance of pools within the nation makes swimming the fourth most-common recreational activity.

However, as your pool liner ages, a replacement is inevitable to rejuvenate the look and feel of your backyard cool spot. An inground vinyl liner replacement also helps maintain the structural integrity of the pool’s foundation. Here are some common issues that lead to the wearing off of your pool installation.

1. Aging

Your swimming pool lining will gradually weaken over time. The average lifespan of a pool liner is approximately 7-10 years. After that, you may need to call in an inground vinyl liner replacement company to fit in a new lining.

2. Sun Damage

Just like the human skin, vinyl liners are susceptible to the harsh UV rays from the sun. The harmful rays bleach and weaken the vinyl over time, leading to the formation of cracks. The sun bleaching also leads to the fading of the liners.

3. Extreme Weather Patterns

Powerful winter storms contrasted by hot summer days take a toll on your swimming pool liner. Tree branches, stones, and organic contaminants can fall into improperly covered pools, ripping apart the vinyl membrane.

4. Over Chlorination

Some homeowners will often put excess chlorine in their pool waters. While it is vital to play safe, these larger doses of chlorine lead to pH imbalances. This eventually leads to corrosion and fading of your vinyl lining.

5. Pet Scratches

While puppy pool parties are fun, your pet’s claws landing on the vinyl can be catastrophic. Your dogs can easily tear the vinyl membrane causing a leak in your swimming pool.

Here are some signs that you need an inground vinyl liner replacement.

Cracks and Tears

Years of exposure to over-chlorinated water and the sun UV rays causes the vinyl layer to deteriorate. The lining starts to crack at the water level, and the rips grow in size in some cases, becoming massive tears. The rest of the vinyl also becomes brittle and tears much more easily, thus leaking water.

Fading and Discoloration

The first sign of an aging vinyl liner is the color fade. Quality liners usually have UV inhibitors and chemicals that slow the fading process. However, the sharp colors and patterns become harder to make out with time. Stains on the liners are unattractive and may necessitate an in-ground vinyl liner replacement.

Wrinkles and Stretching

High-quality vinyl fits like a glove when layered on your pool foundation. The presence of warps and creases on the corners and bottom of your pool may indicate the need for a new liner. The wrinkles may stem from age, poorly installed liners, or low-quality vinyl material.


Normal evaporation may lower your water levels by half an inch a week. If your water levels drop by more than an inch for the week, you may have a pool leak. Replacing the pool liner helps avoid erosion and formation of sinkholes that can affect the structural integrity of the pool foundation.

Several factors may cause your swimming pool lining to weaken over time. An in-ground vinyl liner replacement may save you’re your pool from further damage. The signs above can guide you on the appropriate time to call in the pool liner installation company.
