Pool Resurfacing Cost by Finish: Plaster, Quartz and Pebble

Pool resurfacing cost in 2026: six published estimates compared

No government agency tracks what homeowners pay to resurface a pool, so every number comes from cost guides and companies in the trade. Lined up together, they agree on more than they disagree.

HomeGuide and Angi both put the typical job at $6,000 to $15,000 around an $11,000 average for a pool with 1,000 square feet of surface (HomeGuide; Angi, June 2025). Homewyse, which builds estimates from unit costs, starts basic white plaster at $6.55 to $7.81 per square foot in May 2026, a price that includes draining, sandblasting, patching minor cracks, cleaning and refilling, but not waterline tile (Homewyse). At 1,000 square feet that lands between $6,550 and $7,810, right inside the cost guides’ plaster band.

The outliers come from companies that sell finishes. Skin Micro Plaster, a finish maker, quotes $10,000 to $25,000 for a standard residential resurface, and River Pools puts a 15 x 35 ft replaster at $10,000 and up. Anthony & Sylvan’s range starts lower, at $2,000, without saying what that job includes. Treat any single figure as a starting point: HomeGuide names pool size, pool type and finish as the main price drivers.

Price per square foot by finish: paint, plaster, quartz, pebble and tile

The finish is the biggest choice you make. It sets the upfront price, how long the surface lasts and how it feels underfoot.

Plaster resurfacing cost is the floor for a lasting job: $6 to $8 a square foot for standard white plaster, which HomeGuide says lasts 7 to 12 years. Quartz plaster adds colored quartz to the mix for $7 to $10 a square foot and 10 to 15 years. Pebble finishes run $7 to $15 a square foot and last 15 to 20 years or more, which is why a pebble job can cost less per year than plaster even though the invoice is bigger.

Paint is the cheapest way to change a pool’s look at $1 to $2 a square foot, but HomeGuide gives it 5 to 7 years and Angi just two to five. River Pools adds that epoxy paint adheres only to bare surfaces, and Willsha Pools, a Texas builder, warns that removing paint later adds sandblasting costs. Tile sits at the other extreme: Angi says it costs around 20 times more than paint, which is why HomeGuide and Angi suggest tile above the waterline and a cheaper finish below it.

How much to resurface a 10,000, 20,000 or 30,000 gallon pool

Contractors measure square feet of floor and wall, not gallons. Here is how to turn your pool’s size into the number they will price.

1. Measure length and widthMeasure inside the pool walls. For a freeform pool the result is a rough estimate; Willsha Pools suggests measuring around the whole pool as closely as you can.
2. Find the average depthAdd the shallow and deep end depths and divide by two.
3. Add floor and wallsFloor = length x width. Walls = 2 x (length + width) x average depth. The sum is your interior surface.
4. Multiply by the finish priceUse a per-square-foot range from the finish table above, then add the line items below.

By that math, a pool of about 10,000 gallons (the Akron table’s 12 x 24 ft at 4 ft holds 8,600; 14 x 28 ft at 4.5 ft holds 13,200) has roughly 576 to 770 square feet of surface, or about $3,773 to $6,014 in basic plaster. A 20,000-gallon pool such as 18 x 36 ft at 4.5 ft (21,900 gallons) has about 1,134 square feet, and a 30,000-gallon 20 x 40 ft pool about 1,400. The 20 x 40 ft pool runs from about $9,170 for basic plaster to $21,000 for pebble at the top of HomeGuide’s range.

Concrete, fiberglass and vinyl: what each pool type pays

Concrete (gunite) pools are the classic resurfacing job: HomeGuide puts them at $6,000 to $15,000, with the old plaster sandblasted or chemically etched before the new coat goes on. Fiberglass pools cost $7,000 to $15,000 because the factory gelcoat cannot be reapplied on site; resurfacing uses polymer coatings or pebble finishes over the sanded shell (HomeGuide). River Pools puts a polymer coating on a small to medium pool at $10,000 to $13,000 at minimum.

Vinyl pools get a new liner instead: $3,000 to $7,500 for an inground pool per HomeGuide, or about $4,500 including chemicals and water per River Pools, which says liners last 5 to 9 years. The differences in upkeep between the three types are laid out in our gunite vs fiberglass vs vinyl comparison, and fiberglass shell options are on our fiberglass pool installation page.

Beyond the finish: drain, prep, tile, refill and start-up costs

The finish price is the headline. The full invoice also covers getting the water out, fixing what the empty shell reveals and getting the water back in.

Draining and cleaning run $600 to $650 in HomeGuide’s figures. Once the shell is empty, cracks and leaks become visible, and HomeGuide stresses that they must be fixed before the new finish goes on or they spread into it. Waterline tile is usually a separate line, since Homewyse’s estimate excludes it; Anthony & Sylvan budgets $25 to $30 a square foot, or $2,500 to $5,000 to retile an average pool. Doing it while the pool is empty avoids a second drain later.

Refilling is a utility bill, and it varies more than most owners expect. Under rates in effect on October 4, 2026, refilling 20,000 gallons cost $39.00 in Sacramento and $649.98 in Houston, with a 25-city median of $215.09 (PC&S cost to fill a pool study). HomeGuide puts a water truck at $400 to $2,000, against 12 to 36 hours on a garden hose.

How long a new pool surface lasts, and when it is time to redo it

Lifespan claims vary widely because most of them come from companies that sell resurfacing. The one lending-industry figure sits in the middle.

Fannie Mae’s property condition table for apartment buildings assigns a pool or spa plaster liner an expected life of 8 years (Fannie Mae Form 4099.F). Home-pool sources range from ecoFINISH’s three to seven years for heavily used plaster to Anthony & Sylvan’s 10 to 15 years with good care. HomeGuide’s rule of thumb covers all finishes: resurface every 7 to 15 years, depending on the finish and how well the water is balanced.

• Flaking, peeling or chalky plaster Loose finish or a powdery residue at the edges means the surface is breaking down.
• Rough texture A floor that scrapes feet or snags swimsuits has lost its smooth top layer.
• Stains that will not brush or wash off If an acid wash no longer helps, the stain is in the finish itself.
• Cracks, chips or lost pebbles Openings let water reach the shell; have leaks checked before resurfacing.
• Corroded tile grout Grout failure at the waterline often shows up alongside a tired finish.

Timing matters too. Skin Micro Plaster recommends off-season or mild weather because schedules are more flexible, and a South Florida builder, Master Touch Pools, points owners in Broward and Palm Beach counties to fall and winter so the surface cures before peak swimming. Our pool season length study shows when the swimming months fall in each city.

The 28-day start-up that protects a new plaster finish

A new cement finish is soft for weeks. The National Plasterers Council (NPC) publishes a start-up routine that most plasterers follow; the NPC says a new finish is soft and prone to discoloration and scaling in its first weeks.

1. Fill dayFill from the deepest point without stopping, with a soft cloth over the hose end, and keep people and pets out. Once full, run filtration continuously for at least 72 hours, ideally for 7 days.
2. Day 1Test pH, alkalinity and calcium. Bring alkalinity to 80 to 100 ppm and pH to 7.2 to 7.6. Brush the whole surface at least twice a day. No chlorine for 48 hours, no heater until the plaster dust is gone.
3. Day 2Repeat the tests and raise calcium hardness to 100 to 150 ppm in 10-pound increments, hours apart.
4. Day 3Add chlorine to 1.5 to 3.0 ppm. For salt pools, do not add salt for at least the first 30 days.
5. Days 4 to 7Keep pH and alkalinity in range, raise calcium to at least 200 ppm and begin stabilizer (cyanuric acid) to 30 to 50 ppm.
6. Days 7 to 28Vacuum leftover dust with a brush vacuum; no wheeled cleaners until day 28. Then brush weekly and keep the water balanced.

Start-up chemicals are a small line item, but prices move: our pool chemical price index stood at 124.1 in August 2026 (2019 = 100), 12.7% below its January 2023 peak, using Bureau of Labor Statistics producer prices. Weekly service companies often handle start-up; see our pool service cost guide for what that service costs.

Comparing resurfacing bids: what to ask every contractor

• Same finish, same square footage HomeGuide advises comparing at least 3 estimates for the same finishing materials. Ask each contractor for the measured surface area.
• How the old finish comes off Chipping, sandblasting, hydro-blasting and chemical stripping cost and perform differently; the method should be written in.
• What is included Drain, crack repair, waterline tile, coping, drain covers, refill water and start-up are often priced separately.
• License and insurance Only 14 of 51 jurisdictions issue a dedicated pool contractor license (PC&S license study); check what your state requires.
• Payment schedule In California, CSLB caps a pool contract down payment at 10 percent or $1,000, whichever is less. Never pay in full before work begins.
• Warranty and start-up responsibility Get the finish warranty in writing and note who does the 28-day start-up.

Cheapest ways to resurface a pool without wasting money

• Price per year, not per job. Pebble’s low case works out to about $350 per year of service for 1,000 square feet against $500 for plaster, by our calculation from HomeGuide figures.
• Patch first if the damage is local. Angi says DIY patch kits for small areas cost less than $50, and Anthony & Sylvan prices an acid wash at $150 to $300 to buy time on a stained but sound surface.
• Do the easy prep yourself. Angi estimates owners save about $200 by draining and $250 by cleaning, if the contractor agrees and local drain rules allow it.
• Bundle work while the pool is empty. Tile, lights and leak repairs cost less when nobody has to drain the pool twice.
• Paint only as a stopgap. At $1 to $2 a square foot it is the cheapest finish, but it lasts the shortest time and can complicate the next resurfacing.

If repairs keep stacking up, compare the total with a full renovation on our pool remodeling page, or with the cost of targeted pool repair. For perspective, even HomeGuide’s $15,000 high end for a concrete resurface is about a third of Angi’s $44,499 low end for a new in-ground pool (inground pool cost guide).
