Resurfacing a Swimming Pool: Cost, Materials, and Timeline

Your pool is looking rough. The plaster is cracked, the finish is chalky, and you’re wondering what it’s going to cost to bring it back to life. Pool resurfacing can range anywhere from $3,000 to $25,000 depending on pool size, material choice, and labor costs in your area. Most homeowners in the Inland Empire pay between $8,000 and $15,000 for a standard 15,000-gallon residential pool with basic plaster or aggregate finish.

The good news: you’re not looking at a full rebuild. Resurfacing is the most cost-effective way to extend your pool’s life another 10 to 15 years, bring back that bright finish, and fix surface damage before it becomes structural. This guide covers every material option, real pricing, step-by-step what to expect, and when you can DIY versus when you need the crew.

How Much Does Pool Resurfacing Cost?

Pool resurfacing costs break down into three categories: material, labor, and equipment. Here’s what you’ll actually pay:

Material Costs (per square foot)
– Basic plaster: $3 to $5
– Aggregate finishes (Pebble Tec, Pebble Sheen): $6 to $10
– Fiberglass: $2 to $4
– Tile overlay: $8 to $12

Labor Costs (per square foot)
– Standard plaster: $2 to $4
– Aggregate finishes: $3 to $6
– Fiberglass coating: $3 to $5
– Tile: $5 to $8

Total Project Estimates (15,000-gallon pool, 1,000-1,200 sq ft surface)
– Basic plaster: $5,000 to $9,000
– Pebble or aggregate: $9,000 to $19,000
– Fiberglass: $5,000 to $8,000
– Tile: $13,000 to $20,000

Equipment rental (if you’re doing some of the work yourself) adds $500 to $1,500. Professional resurfacing crews bring their own equipment, so that cost is rolled into labor.

Understanding the Different Pool Resurfacing Materials

Not all pool finishes are created equal. Here’s what each material does, how long it lasts, and what it costs.

Plaster

Plaster is the industry standard and the most affordable option. It’s applied in a smooth, white coat directly to the concrete shell. A good plaster job lasts 10 to 15 years before it needs replacing.

Pros: Low cost, easy to repair small cracks, works with any pool design. Cons: Chalky surface (loose material that rubs off on your hands and clothing), stains easily, requires frequent chemical balancing, needs weekly brushing.

Cost: $5,000 to $9,000 for a 15,000-gallon pool. Best for: Budget-conscious homeowners who don’t mind maintenance and don’t care about a bright finish.

Aggregate Finishes (Pebble Tec, Pebble Sheen, Marcite)

Aggregate finishes are plaster mixed with small pebbles or stone chips. They’re durable, textured, and way more visually appealing than plain plaster. Pebble Tec is the market leader, but Pebble Sheen (Pentair’s brand), Quartz Scape, and others are solid alternatives.

Pros: Lasts 15 to 20 years, bright finish that doesn’t fade, textured surface feels good underfoot, holds color better than plaster, easier maintenance. Cons: More expensive upfront, rougher texture (can be hard on swimwear), harder to repair small damage.

Cost: $9,000 to $19,000 for a 15,000-gallon pool depending on the brand and finish quality. Best for: Homeowners who want longevity, don’t mind paying more upfront, and want a polished look.

Fiberglass Coating

Fiberglass is applied as a thin, gel-coat layer over the concrete shell. It’s becoming popular as a mid-range option between plaster and aggregate.

Pros: Durable (15 to 20 years), smooth finish, low maintenance, fewer chemicals needed. Cons: Expensive labor (specialized application), harder to repair, limited color options, can crack if concrete underneath moves.

Cost: $5,000 to $8,000 for material and labor on a 15,000-gallon pool. Best for: Homeowners who want low maintenance and are okay with moderate upfront cost.

Tile

Tile is the premium option. It’s applied over the pool shell in individual pieces or sheets. A tiled pool looks like a resort and will last 20 plus years.

Pros: Extremely durable, premium look, easy to clean, any color or design possible. Cons: Most expensive option, grouting can fail and allow water to get behind tile, requires skilled installation.

Cost: $13,000 to $20,000 for a 15,000-gallon pool. Best for: High-end homes, commercial pools, or homeowners who want a pool to last 20-plus years without resurfacing again.

Step-by-Step: What Happens During Pool Resurfacing

Understanding the process helps you know what to expect, how long it takes, and where the labor cost comes from.

Week One: Drainage and Demolition

First, we drain the pool completely. This takes one to two days depending on pump size and whether we’re recycling the water (some jurisdictions require it, some don’t). Once drained, we inspect the concrete shell for cracks, movement, or structural damage. Small cracks can be sealed before resurfacing. Large cracks or shell issues need to be addressed before any new finish goes down, or they’ll come right back through.

Next, we acid wash the entire surface. This removes algae, mineral deposits, and old plaster dust. The acid wash opens the concrete’s pores so the new finish bonds properly. We use diluted muriatic acid (typically 1 part acid to 3 parts water) applied with brushes and mops, followed by thorough rinsing with fresh water. The crew wears respirators and gloves throughout. Water disposal requires proper handling per EPA guidelines.

Week One (Continued): Prep Work

After the acid wash, we repair any damage. Small cracks get filled with hydraulic cement or concrete patching compound. We apply a bonding agent (typically a thin adhesive coat) to ensure the new finish sticks to the concrete. We also plug any return line openings, level the bond beam (the top edge of the pool), and ensure proper slope toward the main drain.

This is where “cheap” resurfacing jobs fail. Skipping the bonding coat or not repairing cracks properly means the new finish will delaminate (separate from the concrete) within two to three years. A crew that takes time here will deliver a finish that lasts.

Week Two: Applying the New Finish

For Plaster: We mix fresh plaster to the right consistency and trowel it on by hand in a thin, even coat. The plaster must be applied while the concrete is still damp but not actively wet. Timing is critical. Once applied, we smooth it, let it set for 24 hours, then brush it lightly to smooth any imperfections. Water is then slowly added to the pool over the next week while the plaster cures. Too fast, and the plaster can blister. Too slow, and it hardens unevenly.

For Aggregate Finishes: We apply a base plaster coat first, then the aggregate mixture (which is heavier and grittier than regular plaster) goes on top. It’s troweled smooth, then pressure-washed at a specific PSI to expose the pebbles just enough for the right look and texture. This is skilled work. Too much pressure wastes material and exposes plaster underneath. Too little leaves the finish dull.

For Fiberglass: We clean and prime the concrete, then spray on fiberglass resin in thin coats, alternating direction for strength. This requires ventilation and specialized equipment. Once cured (usually 48 hours), the surface is sanded smooth.

For Tile: We apply a waterproof base coat, then set tiles in thin-set mortar, row by row. Grouting comes next, sealed with epoxy or polyurethane. This takes the longest, two to three weeks for a large pool.

Week Two (Continued): Curing and Refilling

Once the finish is applied, the pool sits. Plaster needs five to seven days before water can be added. Aggregate finishes need similar time. Fiberglass and tile each have their own cure schedules. During this time, the crew covers the pool with plastic to protect against rain and debris.

When refilling begins, we add water slowly (usually 1 to 2 feet per day) while the finish continues to cure. We balance chemicals gradually as the pool fills. Plaster, especially, needs proper chemical care during the first two weeks of cure or it can stain and etch.

Brand-Specific Resurfacing Guidance

If you’re shopping for materials or want to understand what different manufacturers offer, here’s what the major brands bring to the table.

Hayward

Hayward is the oldest player in pool equipment manufacturing, and they make solid finishing products. Their plaster is reliable, and their Hayward branded aggregate finishes are cost-effective alternatives to Pebble Tec. Hayward equipment (pumps, filters) works well with their finishes since they’re designed to work together. If you’re replacing other Hayward equipment while resurfacing, you’re in good shape.

Cost: On the lower to mid-range side. Good value.

Pentair

Pentair owns the Pebble Sheen brand and is a huge manufacturer of pool equipment and chemicals. Their aggregate finishes are excellent quality, though typically more expensive than Hayward’s. They’re known for bright, long-lasting finishes. If you run Pentair equipment (many pools do), their finishes integrate well.

Cost: Mid to high-range. Premium materials and reliability.

Jandy (part of Pentair)

Jandy is a Pentair brand focused on pool automation and controls. While they don’t make finishing materials directly, their equipment (valves, heaters, automation) is top-tier, and their customer base tends to choose high-end finishes like Pebble Tec or Pebble Sheen to match the quality of their equipment.

Cost: If you’re using Jandy equipment, expect to pair it with mid to high-end finishes.

Zodiac

Zodiac is an Australian company known for quality fiberglass pools and coatings. If you’re considering fiberglass resurfacing, Zodiac products are solid. They’re becoming more available in the US and offer good warranty support.

Cost: Mid-range to high-range. Quality workmanship required for proper application.

Polaris

Polaris is known for robotic pool cleaners, not finishing materials. However, many pool owners with Polaris equipment tend to invest in better finishes to protect their overall investment. Polaris owners are typically detail-oriented about pool care.

Cost: Not directly related to finishing costs, but Polaris-owning pools tend to get premium finishes.

When Should You Resurface Your Pool?

Resurfacing isn’t a guess. There are clear signs that your pool needs it.

Resurface now if you see:
– Cracks wider than 1/8 inch that aren’t just surface cracks
– Rough, chalky plaster that’s rubbing off on your hands and swimwear
– Stains that won’t come out no matter how much you scrub or use chemicals
– Visible concrete showing through the finish
– Water leaking from the pool (constant dropping of water level beyond normal evaporation)
– Bumps or bulges in the floor or walls

You can wait if:
– Your plaster is just a little dull but has no structural damage (usually good for another 1-2 years)
– You have minor surface cracks (less than 1/8 inch) with no leaking
– The finish is aging but the concrete shell is solid

Most pools need resurfacing every 10 to 15 years. If your pool is older than 12 years and showing any of the above signs, it’s time to get quotes.

DIY Pool Resurfacing: What You Can Actually Do Yourself

Full resurfacing is not a DIY job for most homeowners. The skill level is high, and mistakes are expensive to fix. That said, there are parts of the process where a homeowner can save money by doing some of the work.

What You Can DIY

Acid washing: If you’re experienced with harsh chemicals and have proper safety gear (respirator, gloves, eye protection), you can acid wash the pool yourself. Cost savings: $800-$1,500 in labor. Rental equipment for pressure washing and acid distribution: $300-$500.

Drain and pump: You can rent a pump and handle the initial drain if you want. This saves $300-$500 in labor.

Water recycling: Some jurisdictions allow homeowners to use existing pool water after acid wash (filtered and chemically balanced). This saves on water costs.

What You Should NOT DIY

Finishing application: Plaster, aggregate, fiberglass, and tile all require skill. Plaster mixed wrong, applied at the wrong humidity, or cured poorly will fail within months. Aggregate requires the right pressure wash technique or it comes out wrong. Fiberglass needs proper ventilation and spray technique. Tile needs proper waterproofing underneath. These are crew jobs.

Structural repair: If there are cracks in the concrete shell, movement, or structural damage, get a professional. A bad repair fails immediately after resurfacing.

Chemical balancing during cure: Many homeowners don’t realize that the first two weeks of cure are critical for chemical balance. Too much pH or alkalinity during cure and plaster stains and etches permanently. This is where many DIY attempts fail.

Budget-Conscious Approach

If you want to save money, here’s the real move: Do the prep work yourself (acid wash, pump removal, basic cleanup), then hire the crew for the actual finish application and curing supervision. You’ll save $1,500-$2,500 and the finish won’t suffer.

Or, choose a simpler material. Plaster is cheaper than aggregate, and fiberglass is middle ground. You get what you pay for on longevity, but a $5,000 plaster job looks brand new for the first five years.

Pool Resurfacing Cost by Pool Size

Not all pools are 15,000 gallons. Here’s how cost scales:

| Pool Size | Surface Area | Basic Plaster | Aggregate Finish | Fiberglass | Tile |
|, -|, -|, -|, -|, -|, -|
| 10,000 gallons | 700-800 sq ft | $3,500-$6,000 | $6,000-$13,000 | $3,500-$5,500 | $8,500-$14,000 |
| 15,000 gallons | 1,000-1,200 sq ft | $5,000-$9,000 | $9,000-$19,000 | $5,000-$8,000 | $13,000-$20,000 |
| 20,000 gallons | 1,300-1,500 sq ft | $6,500-$11,500 | $12,000-$25,000 | $6,500-$10,500 | $17,000-$27,000 |
| 25,000+ gallons | 1,600+ sq ft | $8,000-$14,000 | $15,000-$30,000 | $8,000-$13,000 | $20,000-$35,000 |

Larger pools cost more in absolute dollars but often have slightly lower per-square-foot costs due to economies of scale.

Geographic Cost Variations

Labor costs vary dramatically by region. The Inland Empire (Rancho Cucamonga, Upland, Ontario, Etiwanda, Alta Loma) sits in a competitive market with solid pricing, but you’re not looking at cheap California labor either.

Inland Empire Pricing:
– Basic plaster: $3,000-$8,000 for a 15K gallon pool
– Aggregate finishes: $8,000-$17,000
– Fiberglass: $4,500-$7,500
– Tile: $12,000-$18,000

Why it varies:
– Materials shipped to remote areas cost more
– Labor availability (some regions have fewer crews)
– Local competition (markets with more crews have lower prices)
– Travel time (crews in rural areas charge for drive time)

In the Inland Empire, you’re in a sweet spot. Enough competition to keep prices honest, enough demand that crews can be selective about quality jobs.

How Long Does Pool Resurfacing Take?

Full resurfacing typically takes two to three weeks from drain to refill.

Timeline:
– Days 1-2: Drain and acid wash
– Days 3-4: Repairs and prep
– Days 5-7: Finish application
– Days 8-14: Cure time
– Days 15-21: Refill and chemical balancing

If you have a large pool or complex finish (tile, multiple colors), add another week. Weather delays are common in Southern California, if it rains during application or cure, the job extends. We plan for it, but it happens.

The crew will give you a start date and expected completion date. A good crew will stick to it.

Professional vs DIY: The Real Decision Tree

Hire a professional if:
– You want the finish to last 10-20 years without failure
– You can’t afford to do the work twice
– You don’t have the equipment, skills, or time
– Your pool has structural damage
– You’re not comfortable working with acid or resin

DIY some steps (with professional finish) if:
– You’re mechanically inclined and safety-aware
– You want to save $1,500-$2,500 on labor
– You can handle acid washing and basic prep
– You’ll still hire the crew for the finish

Full DIY only if:
– You have prior pool resurfacing experience
– You’re okay with a potential $3,000-$5,000 redo if it fails
– You have time, equipment, and proper ventilation

For 95% of homeowners, calling the crew is the right call. We’ve seen this before, and we do it right the first time.

Common Pool Resurfacing Mistakes to Avoid

These are the mistakes we see that cost homeowners extra:

Skipping the bonding coat: New finish won’t stick properly. It delaminated within a year.

Rushing the acid wash: Algae and mineral deposits left behind prevent the finish from bonding evenly.

Poor chemical balance during cure: Plaster stains, etches, and discolors. This is irreversible.

Not repairing cracks before resurfacing: Cracks come right back through the new finish.

Choosing the cheapest contractor: You get what you pay for. A crew cutting corners on prep or materials won’t stand behind the work. Get references.

Not getting a detailed quote: “Looks like about $8,000” is not a quote. You want itemized material, labor, and timeline in writing.

Failing to maintain the pool after resurfacing: Plaster, especially, needs brushing and proper chemistry for the first year. Aggregate is more forgiving.

FAQ: Pool Resurfacing Questions

How much does it cost to resurface a swimming pool?

Between $3,000 and $25,000 depending on size and material. Most Inland Empire pools fall in the $8,000 to $15,000 range for plaster or aggregate.

How often do you need to resurface a pool?

Every 10 to 15 years on average. Plaster lasts 10-15 years, aggregate 15-20, fiberglass 15-20, tile 20-plus.

Can you resurface an inground pool yourself?

You can handle some prep work (draining, acid washing) if you’re careful, but the finish application should be professional. Mistakes here are expensive.

What is the cheapest way to resurface a pool?

Basic plaster is the cheapest option (about $5,000-$9,000 for a 15K gallon pool). Fiberglass coating is a close second and requires less maintenance. Aggregate costs more upfront but lasts longer, bringing down the cost per year.

How long does pool resurfacing take?

Two to three weeks from drain to refill, including cure time.

What material lasts the longest?

Tile lasts 20-plus years with proper maintenance. Aggregate (Pebble Tec, Pebble Sheen) lasts 15-20 years. Fiberglass lasts 15-20 years. Plaster lasts 10-15 years.

Do you have to drain the pool to resurface it?

Yes. The entire surface must be exposed, cleaned, and prepped. There’s no way around it.

Can you patch a pool instead of full resurfacing?

You can patch small cracks and damage, but once the plaster is chalky, stained, and cracking in multiple places, patching is temporary. A full resurface is the real fix.

Why is my pool leaking after resurfacing?

If it’s leaking soon after (within the first month), the crew didn’t let the finish cure properly before refilling. If it starts months or years later, the concrete shell probably has a crack that wasn’t sealed before resurfacing. This happens when prep work is rushed.

What’s the difference between plaster and aggregate?

Plaster is smooth but needs more maintenance and doesn’t last as long. Aggregate (mixed with pebbles or stone) is textured, brighter, more durable, and needs less maintenance, but costs more upfront.

Ready to Resurface? Here’s What to Do Next

You’ve got the cost breakdown, the timeline, and the reality of the different materials. Here’s the next step.

Get two to three quotes from crews in the Inland Empire that have been around and know what they’re doing. A good crew will inspect your pool, ask about your maintenance habits, explain what they’ll do and why, and give you a detailed quote with material and labor broken out.

Watch for red flags: crews that avoid looking at the concrete carefully, give you a vague price range, or pressure you to decide immediately. Good crews are booked out and don’t need to rush you.

Once you’ve decided on material and crew, ask for references. Call them. Ask how long the finish lasted, whether the crew showed up on time, and whether they stood behind the work if something went wrong.

If you’re in the Inland Empire and ready to move forward, we’ve got 25 plus years of resurfacing work behind us. We’ll diagnose what your pool needs, walk you through material options honest and straight, and get your pool done right. The crew will show up when we say we will, and the finish will hold up.
