Above-ground pools cost about $10 to repair (DIY kit), and average $1,700 for complete replacement. Inground pools, however, cost an average $20 to patch (DIY Kit) and $5,000 for resurfacing if it's not damaged. The cost of a pool varies depending on its type. I'll explain why below.
Gelcoat pool coatings are applied in factories so they can't be replicated at home. Instead, there are replacement coatings--thermoplastic polymers that are used to resurface fiberglass. Before the new coat can be applied, the pool must have been completely drained.
The most common in-ground pools are concrete shells that have been finished with a type of Portland cement-based material, known in the pool trade as “plaster,” that seals and protects the shell. In many instances, the plaster is coated with paint, epoxy, or even fiberglass. The plaster can also serve as a substrate for tile.
