Pool Resurfacing: What It Costs, How It Works, and When You Need It

What is pool resurfacing?

Resurfacing replaces the interior surface of the pool — the layer you touch and see — while keeping the existing gunite or concrete shell. The old finish is chipped out mechanically, the shell beneath it is inspected and repaired, a bond coat is applied, and a new finish is troweled on and water-cured. It is different from a patch or a paint-over: resurfacing removes the failed material rather than covering it, which is why it lasts a decade or more instead of a season. Resurfacing is sometimes called replastering, pool refinishing, or recoating; on a gunite pool these all describe the same work, with the finish material being the variable.

• Resurfacing: old finish removed to the shell, new finish applied — 10-20 year lifespan
• Spot patching: isolated repair, rarely color-matches, appropriate for a single chip
• Pool paint: a coating over the old surface, typically 2-5 years, not something we recommend on gunite
• Full remodel: resurfacing plus tile, coping, decking, or equipment in one mobilization

How much does pool resurfacing cost?

A typical Dallas-Fort Worth residential gunite pool runs $8,000 to $18,000 to resurface, with the finish material and the pool's square footage driving nearly all of the spread. White plaster sits at the bottom of the range, quartz aggregate in the middle, and premium pebble at the top. These figures assume the tile, coping, and decking are staying and only the interior is being replaced — bond beam repair, plumbing repair, or tile replacement are priced on top.

Ranges are what we see across DFW, not a quote. Pool size, access to the backyard, and condition found after draining move the number, which is why we price only after an on-site inspection.

What moves the price up or down

• Surface area — finishes are priced per square foot, so a 600 sq ft pool costs roughly double a 300 sq ft one
• Finish material and color grade, the single biggest controllable factor
• Shell condition found after chip-out: bond beam spalling, cracks, or delaminated gunite
• Plumbing repairs — cracked returns or main drain lines that only show once the pool is dry
• Whether waterline tile and coping are replaced in the same drain-down
• Backyard access: material hand-carried through a house costs more in labour than a wide gate

Combining tile, coping, or decking into the same project always costs less than a second mobilization later, because the drain, fill, and crew setup are already paid for.

Signs your pool needs resurfacing

The most common sign is texture — a finish that feels rough or sandpaper-like under bare feet has lost its smooth top layer and is exposing aggregate underneath. Staining that won't respond to brushing or acid washing, especially dark or rust-colored blotches, usually means the surface itself has been compromised, not just the water chemistry. Cracking, delamination (finish separating from the shell in sheets or bubbles), and chronic cloudy water after balanced chemistry are all indicators worth a professional look.

• Rough, sandpaper-like texture that scrapes feet and swimsuits
• Staining that doesn't respond to acid washing
• Visible cracks or hollow-sounding spots when tapped
• Finish flaking, bubbling, or delaminating in sheets
• Chronic cloudy water despite correct chemical balance
• Exposed aggregate or grey gunite showing through
• Rising chemical consumption as an etched surface keeps consuming acid

Why finishes wear out early in Texas

DFW's water is naturally hard, and high calcium content accelerates scaling and rough texture on plaster surfaces faster than it would in areas with softer water. Intense summer sun and wide temperature swings between winter and summer also stress the finish through repeated expansion and contraction. Pools that run at low water levels for extended periods, or that see aggressive chemical dosing to fight algae, tend to wear out ahead of schedule regardless of the finish type. Local soil is the other Texas factor: expansive clay across Tarrant County moves seasonally, which is why we inspect the bond beam on every pool we drain rather than assuming the shell is sound.

The resurfacing process step by step

A straightforward resurface runs 7 to 10 working days from drain to refill. The window between chip-out and bond coat is when hidden problems get found, which is why any fixed-price quote should include an agreed process for shell or plumbing repairs discovered along the way — documented with photos and approved before the extra work happens.

1. 1

   Drain the pool

   Drain the pool completely, timed so the empty shell isn't left standing through heavy rain or a hard freeze.

2. 2

   Chip out the old finish

   Mechanically chip out and remove the old plaster, quartz, or pebble down to sound gunite, including behind the waterline tile band where it is being replaced.

3. 3

   Inspect and repair the shell

   Inspect the dry shell, bond beam, and plumbing lines. Repair spalling, structural cracks, and cracked returns or main drain lines before any new material goes on.

4. 4

   Replace tile and coping if included

   Set new waterline tile and reset or replace coping while the pool is dry, if that work is part of the project.

5. 5

   Apply the bond coat

   Apply a bond coat over the prepared shell so the new finish adheres mechanically rather than sitting on old material.

6. 6

   Apply the new finish

   Trowel on the new plaster, quartz, or pebble finish in a continuous application, then expose and wash pebble finishes to reveal the aggregate.

7. 7

   Acid wash and begin a controlled refill

   Acid wash or brush the finish, then start a continuous refill — stopping and restarting the fill can leave a permanent ring.

8. 8

   Balance start-up chemistry

   Balance pH, alkalinity, and calcium hardness through the first 24 to 72 hours and brush daily for the first two weeks while the finish cures.

Resurfacing by pool construction type

Almost every pool we resurface in DFW is gunite or shotcrete, which is what the process above describes. Other shell types behave differently, and it's worth knowing which one you have before comparing quotes.

• Gunite / shotcrete: chip out and re-finish with plaster, quartz, or pebble — the standard DFW resurface
• Fiberglass: cannot be plastered; the gel coat is repaired or re-coated, which is a different trade
• Vinyl liner: has no finish to resurface — the liner is replaced instead, typically every 8-12 years

How long each finish type lasts

• White plaster: roughly 10-15 years
• Colored or polished plaster: roughly 10-15 years, often on the shorter end due to fading
• Quartz aggregate finishes: roughly 12-18 years
• Pebble finishes: roughly 15-20+ years depending on quality and maintenance

These are typical ranges, not guarantees — water chemistry, water balance consistency, and how the pool is used all shift the actual lifespan up or down. A pebble finish that costs 50% more than plaster upfront usually costs less per year of service.

Start-up care after resurfacing matters

The first two to four weeks after a new finish is applied are critical to how it looks and performs for the next decade. New plaster and quartz surfaces need controlled brushing and gradual chemical introduction to cure properly and avoid blotching or plaster dust. Running the pump on the schedule your contractor recommends, and not shocking the pool heavily in the first week, protects the investment you just made.

• Brush the whole surface daily for the first two weeks to lift curing dust
• Run the pump continuously for the first 72 hours of the fill
• Hold off on chlorine shock and salt for the period your contractor specifies
• Keep calcium hardness and pH in range — an aggressive fill can etch a brand-new finish

How to judge a resurfacing quote

The cheapest bid and the most expensive bid on the same pool often describe different scopes, so compare the written scope rather than the total. A useful quote names the finish product and color, states the tile allowance, says what happens if shell repair is needed, and gives a deposit that is a modest percentage rather than most of the job.

• Named finish product and color, not just "new plaster"
• Written handling of bond beam and plumbing repairs found after draining
• Whether start-up chemical service and the initial fill are included
• Warranty length on both the material and the workmanship
• A licensed, insured local contractor who pulls the permits your city requires

Resurfacing versus other repair options

Resurfacing addresses the interior surface only — it doesn't fix cracked decking, failing equipment, or outdated tile. If those issues exist too, it's often more efficient to combine them into one project since the pool is already drained. If the shell itself has structural problems beyond the surface, resurfacing alone won't solve it and a fuller renovation may be the better long-term answer.
