Fiberglass Pool Resurfacing: Benefits, Process & Cost (2025 Guide)

Why Fiberglass Re-Lining is the Best Long-Term Solution for Your Old Pool

If your existing pool surface is cracked, rough, leaking, or stained, a full replacement is not your only option. Fiberglass pool resurfacing (or re-lining) offers a durable, cost-effective, and long-lasting alternative to replacing the entire structure. Crispy Pools specializes in transforming old concrete, marbelite, or worn fiberglass pools into sleek, low-maintenance backyard centerpieces.

This guide answers all your questions about the benefits, process, and cost of giving your pool a new lease on life with fiberglass

What Exactly is Fiberglass Lining?

Top 7 Benefits of Fiberglass Re-Lining

The choice to resurface with fiberglass offers multiple short-term and long-term advantages that save you money and time:

Superior Durability & Lifespan: Fiberglass is known for its strength and flexibility, resisting cracking and wear. A professionally maintained fiberglass lining can last between 15–25 years, often outlasting traditional marbelite.
Sleek and Leak-Proof: The application creates a seamless, non-porous, and watertight barrier, ensuring your pool is protected from leaks and ground movement.
Extremely Low Maintenance: The smooth, non-porous surface is highly resistant to algae and staining, meaning you spend less time scrubbing and require fewer chemicals.
Saltwater Friendly: Fiberglass handles the effects of saltwater chlorination systems with ease, providing a luxurious, gentle swim experience without damaging the finish.
Aesthetic Customization: Clients can choose an entirely new pool colour and integrate a wide range of mosaics directly into the lining, which cannot break or fall off.
Fast Installation: The entire process is relatively quick, typically taking only 2–5 days, significantly minimizing the downtime of your pool.
Cost-Effective Alternative: Fiberglass re-lining is often a far more affordable and faster solution compared to completely replacing an old pool structure.

How Much Does It Cost to Fiberglass Resurface a Pool?

The cost to resurface a pool with a high-quality fiberglass system (using materials like NCS and Scott Badder) is a significant factor in your decision.

You can expect to spend upwards of R12,000 to R75,000 or more for a full fiberglass resurfacing project.

The final price depends entirely on several key factors:

Pool Size and Depth: Larger pools require significantly more material and labor.
Condition of the Surface: Extensive preparation, structural crack repairs, or osmosis treatment will increase labor costs.
Material Selection: Using premium, UV-resistant gelcoats and resins ensures longevity but affects the price.
Required Prep Work: The state of the current concrete or marbelite surface dictates the amount of sanding and patching needed.

Step-by-Step: The Fiberglass Resurfacing Process

Here is the standard process Crispy Pools follows:

Drainage and Assessment: The pool is drained, and a detailed assessment is conducted to identify all cracks, blisters, and structural issues.
Surface Preparation: The old surface (whether marbelite, plaster, or old fiberglass) is removed, cleaned, and prepared. The surface must be clean, dry, and sound to ensure optimal adhesion.
Structural Repair: Any damage, such as cracks or osmosis, is expertly repaired and sealed.
Fiberglass Application: Layers of new fiberglass matting and resin are applied to the pool shell, creating a new, reinforced structure.
Gelcoat Application: A high-quality, pliable gelcoat is applied over the fiberglass for a durable, smooth, and attractive finish.
Curing and Refill: The new lining is allowed to cure (harden). Final accessories are reconnected, and the pool is refilled.
