How Long Do Fiberglass Pools Last?
The answer to how long do fiberglass pools last is a multi-part answer. When considering, it’s important to remember that a fiberglass pool is manufactured off site and brought to your property. This means the fiberglass pool is prefabricated and there is little to no work on your property. Besides small plumbing connections and backfilling after the pool is placed in the hole, there is “construction process” at the installation site. This will become more important later on as we get into the potential reasons your pool might not last as long as nearly everyone claims.
Generally speaking, a fiberglass pool doesn’t break down all at once. Instead, it’s better to ask how long each part of a fiberglass pool will last. First, the fiberglass shell itself will last the longest. These fiberglass shells are durable and typically last between 20-30 years. However, you will need to make renovations to the deck and coping within 5-15 years. Also if the installers uses flexible PVC, this can require renovation as early as 5 years. Therefore, a fiberglass pool will have a life of 20 – 30 years, but you’ll need to make small cosmetic improvements every 5 – 15 years depending on usage.
2 Main Reasons Fiberglass Pools Don’t Last
Though the shell of the fiberglass pool will last virtually forever, if the plumbing, electrical, and backfilling are not done correctly, that won’t matter. Unfortunately, it’s common for even experienced fiberglass pool installers to try and speed up the installation by using flexible PVC. This makes the initial install quick and reduces fittings and labor costs, but reduces the lifespan of your plumbing. The downside of flexible PVC is obvious. It cracks under pressure and is easy for bugs to build a home inside.
Additionally, due to the complexity of a proper installation of a fiberglass shell in the first place, it’s not uncommon for the electrical and plumbing conduits to be improperly backfilled and for soil consolidation to occur over time around a fiberglass pool. This means your deck will sink around the pool creating an unsightly uneven deck. The deck sinking will create tripping hazards next to the pool.
Granted all these problems listed above are preventable by using a good fiberglass pool installer. Unfortunately, these issues are so common in the industry, it’s worth mentioning. If you are considering buying a house with a fiberglass pool, it’s a good idea to get it inspected. You should have this done by a home inspector with fiberglass experience.
