Pool resurfacing costs. O’Hanlon and Maroney say resurfacing with the pebble-based material costs $4.75 to $5 for each foot of internal surface area. Therefore, a pool with an internal area of 1,000 feet will cost around $5,000 to resurface. Maroney says the typical resurfacing job costs $4,500 to $5,000, but the same job could cost three times as much in northern states.
