Common Problems with Fiberglass Pools and How to Address Them

While fiberglass pools are known for their durability and ease of maintenance, like any other type of pool, they can develop certain issues. In this chapter, we'll explore some common problems and provide solutions for them.

Problem 1: Spider Cracks

These small, hairline cracks may appear on the surface of a fiberglass pool. While they don't typically affect the structural integrity of the pool, they can be unsightly.

Solutions: Spider cracks often result from improper handling during installation. They can also be caused by large shifts in the ground under the pool. While they're difficult to prevent entirely, ensuring proper installation and ground preparation can reduce their likelihood. If they do occur, they can be repaired by applying a layer of gel coat to the pool surface.

Problem 2: Bulges in the Pool Wall

If the pool was not installed correctly or if the backfill material was not compacted properly, bulges may appear on the pool walls.

Solutions: In some cases, these can be fixed without having to replace the pool. Draining the pool and compacting the backfill may correct the issue. In severe cases, the pool may need to be replaced.

Problem 3: Discoloration

Fiberglass pools can sometimes become discolored over time due to chemical imbalances, minerals in the water, or algae growth.

Solutions: Regular maintenance, including monitoring water chemistry, can prevent most discoloration. If discoloration does occur, it can often be corrected with pool chemicals or professional cleaning.

Problem 4: Leaks

Leaks can occur in any pool, and fiberglass pools are no exception. They can be caused by a number of issues, including damage to the pool shell, problems with the pool equipment, or issues with the plumbing.

Solutions: Regular inspection of your pool and its equipment can help detect leaks early. If you suspect a leak, it's important to address it immediately to prevent further damage. In many cases, leaks can be repaired without having to replace the entire pool.

Problem 5: Osmotic Blisters

Osmotic blisters can occur when water penetrates the gel coat of the pool and interacts with the fiberglass, causing bubbles or blisters to form.

Solutions: Preventing osmotic blisters involves proper pool installation and regular maintenance. If they do occur, they can be repaired by draining the pool, opening up the blister, drying it out, and then applying a new layer of gel coat.

While these problems can occur, they are not the norm, and many can be prevented or mitigated with proper installation and regular, diligent maintenance. In the next chapter, we will discuss the life expectancy and long-term care of your fiberglass pool.
