Pool resurfacing in 2026 averages $6,000-$15,000 for a typical 20x40 foot pool with roughly 1,000 square feet of interior surface. By finish type: plaster runs $4-$8 per square foot ($4,500-$9,000 total), quartz runs $6-$9 per square foot ($7,000-$12,000 total), pebble runs $8-$12 per square foot ($10,000-$15,000 total), and tile runs $4-$30 per square foot ($12,000-$40,000 total for full waterline-to-floor tile). Pool surface resurfacing becomes necessary when the original interior finish reaches end of life and shows spalling, rough texture, persistent staining, or visible cracks.
Standard plaster lasts 7-12 years with industry average at 10 years before replastering. Quartz lasts 12-15 years, pebble lasts 15-20 years, and tile lasts 20+ years. Lifespan varies substantially with maintenance — weekly chemistry checks, monthly brushing, and prompt stain treatment all extend finish life. Most owners reach the resurfacing decision 8-12 years after original pool install, which makes this a predictable mid-life pool ownership cost.
Pricing in this guide is aggregated from Angi, HomeGuide, Pool Research, and Aqua Creations 2026 data. Use the calculator above to scope your pool surface area and finish type, then read on for the 30-year total cost comparison across finish types, the 5-item vetting checklist for pool refinishers, and the timeline that takes your pool out of service 10-30 days depending on cure requirements. For surface area math before quoting, the pool volume calculator handles interior dimensions; for full pool replacement comparison, the inground pool install cost calculator scopes rebuild-vs-resurface decisions on older pools.
