Swimming pools are prone to aging. As time goes by, the surfaces suffer wear and tear. Resurfacing, therefore, is periodically required in order for upkeep. Historically speaking, plaster, marble quartz, or cement were the resurfacing materials most commonly used. However, these products are costly. More and more homeowners are looking into fiberglass for their resurfacing needs. This is true for all pool service jobs, including repairing existing pool enclosures.
