Pool resurfacing costs $6,000 to $15,000, depending on the pool's size, type, and the material used for finishing. Most inground pools have plaster surfaces. The cost to replaster a pool is $6,000 to $8,000.

Resurfacing with other finishing materials like pebble, aggregate, or polymer costs up to $15,000. After the materials dry fully, refilling the pool with water costs $40 to $2,000.

Pool resurfacing is the act of removing the existing finish by chipping, sandblasting, hydro-blasting, or chemically removing it. After that, the contractor replaces the finish with a new surface made of plaster, aggregate, tile, paint, or polymer. Resurfacing gives your pool a fresh appearance and extends its lifespan by preventing new cracks and leaks.

Look for these signs that indicate your pool needs resurfacing:

• Flaking or peeling
• Chips or cracks
• Stains or discoloration that you can't clean off
• Rough texture 
• Loss of pebbles or other aggregate
• Corroded grout between tiles
• Chalky residue near the edge

You should resurface a pool every 7 to 15 years, depending on the finish it has. Plaster only lasts about 7 to 12 years, while aggregate or pebble finishes last 15+ years. Maintaining proper pH balance and keeping the water clean will increase the overall lifespan of the pool's surface.

Resurfacing a pool takes 5 to 7 days, depending on the pool's size, material, and finish. Larger pools take more time and effort than small, compact ones.

For the best results, hire a professional by following these helpful tips:

• Compare 3 or more estimates for resurfacing with the same finishing materials.
• Choose a company that specializes in pool resurfacing instead of just cleaning.
• Look for members of the Association of Pool and Spa Professionals (APSP).
• Read pool company reviews on HomeGuide and Google.
• Select a licensed, bonded, and insured pool company.
• Get a written, itemized estimate and contract.
• Don't pay in full before the work begins.

Ask pool resurfacing contractors these questions to make sure the job goes smoothly:

• How long has your company been in business?
• Are you licensed, bonded, and insured?
• Are you an APSP member?
• Can you give me any references from recent resurfacing projects?
• What material do you recommend for my pool, and why?
• How long will resurfacing job take?
• How soon should I fill the pool with water afterward?
• Do you guarantee your work or offer a warranty?
