The lifespan of inground pools will vary based on the material. A concrete pool has no defined expiration date, but the concrete typically requires a resurfacing every 10 years. On average, vinyl-lined pools will need to be replaced every 6-12 years, while fiberglass models can last 30 years or more.
How Long Do Fiberglass Pools Last?
Fiberglass pools last about 30 years and will not require any replacement or replastering like other pool models. Fiberglass is an extremely durable material and it isn’t porous like concrete. This ultimately reduces the risk of any cracks forming. There is also no pool liner or walls that need to be replaced.
Pool owners could choose to apply a gel coating that reinforces the pool. This process will only need to occur once every 15 years or so. Apply the gel coating in unusual cases when you notice any cracking, blistering, or discoloration.
- Fiberglass Pool Typical Lifespan: 30 years.
How Long Do Vinyl Pool Liners Last?
The typical vinyl pool liner will last between 6-12 years, as mentioned. However, it is possible these liners can last up to 15 years. Over time, sun exposure can dry or even crack the liner, especially closer to the surface. This, in addition to long-term chemical exposure in the water, will age the liner.
Age isn’t the only indicator, as you will need to replace the liner sooner if other warning signs are noticed. Take note of signs like cracking, fading, leaking, and wrinkling.
Vinyl liners are designed to have some elasticity, so the biggest sign that you’ll need a replacement is the natural stretch going away. To combat this issue, use a pool cover to reduce sun exposure. You’ll want to have your pool’s water chemistry checked regularly. When the pH dips too low, the acidic water could deteriorate the liner.
- Vinyl Pool Liners Typical Lifespan: 6-12 years.
How Long Do Concrete Inground Pools Last?
The concrete used as a foundation of the inground pool can last 50-plus years. The problem with these pools is they will need a surface refinishing every 10 years. This process will cost between $10,000-$20,000, according to RiverPools. While the expenses will add up as time goes on, concrete can’t be beat when it comes to longevity.
You will know when a refinishing is called for. Once you notice cracks, staining, or roughness, it’s time to refinish. You can preserve your concrete pool by cleaning and brushing the walls regularly. Chemical buildup should be removed to prevent corrosion.
