While many factors affect the cost of resurfacing a pool, CostHelper reports that the cost to resurface the average home pool ranges between $2,500 and $5,500 in 2014. Resurfacing requires draining the pool and takes a minimum of three days before beginning the refilling process.
Concrete pools must be resurfaced approximately every 10 years to keep them in good shape and protect the buyer's initial investment. Fiberglass pools last up to 25 years without resurfacing, a factor that should be considered when deciding on the type of pool to install. While vinyl pools offer a less expensive initial investment, liners require replacement every 5 to 10 years, increasing overall costs.
When it is time to resurface a pool, many owners choose to include other upgrades that increase the cost of the process. If the owner decides to replace waterline tiles, repair electrical problems and install new decking at the time of resurfacing, the overall cost easily increases to $22,000 or more.
Regardless of the type of pool installed, homeowners should consider operational costs. Electricity and supplies can easily add $1,000 to $3,000 to the homeowner's annual budget, not including the cost of resurfacing. Opening, closing and maintaining the pool often involves a major time investment as well.
