Fiberglass pools are known for their durability, low maintenance, and sleek aesthetics—but like any home improvement investment, they can occasionally present issues if not installed or maintained properly. At Rainforest Pools, we believe in transparency, education, and long-term customer satisfaction. Here are the top 5 fiberglass pool problems and our expert solutions to help you enjoy your pool worry-free.


1. Gelcoat Fading or Discoloration

The Problem:

Over time, exposure to UV rays and chemical imbalances can cause the gelcoat surface of a fiberglass pool to fade, chalk, or discolor—especially in lower-quality imports.

The Solution:

* Use UV-resistant topcoats and maintain proper water chemistry (especially pH and chlorine levels).
* At Rainforest Pools, we apply marine-grade gelcoats developed for long-term outdoor exposure.
* Annual inspections and routine cleaning with non-abrasive products can extend color brilliance for decades.


2. Pool Surface Cracks (Spider Cracks)

The Problem:

* Hairline surface cracks, also known as “spider cracks,” can occur due to shipping stress, poor installation, or minor impacts.

The Solution:

* These are cosmetic, not structural in most cases. A professional can repair them using a fiberglass patch and color-matched gelcoat.
* Our pools are manufactured and transported with reinforced structural supports to minimize transit stress.
* We train our authorized installers to handle your pool with care and install it to specification guidelines that reduce settling and stress points.


3. Pool Bulging or Warping

The Problem:

Improper backfilling or failure to manage groundwater during installation can cause the pool walls to bulge or shift.

The Solution:

* Proper site prep and crushed stone backfill allow for stable, even support.
* We incorporate hydrostatic relief systems and recommend professional drainage planning.
* With our trained dealer network, you get certified installation with accountability from excavation to final fill.


4. Osmosis (Blistering or Bubbling)

The Problem:

Osmotic blistering can occur when water penetrates the gelcoat and forms bubbles under the surface—typically after years of exposure and only in pools with poor-quality resin.

The Solution:

* We only use premium-grade vinyl ester resins to form a water-resistant barrier during manufacturing.
* Routine maintenance and early detection can prevent widespread issues.
* If osmosis occurs, a professional resurfacing can restore integrity—although it’s extremely rare in modern, high-quality pools.


5. Poor Fit with Pool Accessories or Plumbing Issues

The Problem:

Misalignment with skimmers, returns, or lights often comes from rushed or careless installation—leading to leaks, inefficiency, or costly repairs.

The Solution:

* At Rainforest Pools, we precision-mold every model to match industry-standard fittings.
* Our detailed installation guides and trained dealers ensure components are installed correctly the first time.
