Pool Resurfacing
Resurfacing replaces the interior finish lining your pool shell. It is the most common pool remodel, the largest single line item on most projects, and the one with a genuinely predictable service life — which means it is also the most plannable.
What resurfacing actually involves
Your pool is a concrete shell — gunite or shotcrete in most in-ground pools — and concrete is porous. The interior finish is a separate layer applied over it: plaster, or plaster blended with quartz or pebble aggregate. It waterproofs the shell, gives the water its colour, and provides the surface you actually touch.
That layer wears out. Water chemistry slowly erodes it, calcium builds on it, and eventually the smooth surface gives way to exposed aggregate, roughness and staining. Resurfacing removes the old layer down to the shell and applies a new one. It is not a coating sprayed over the top of the old finish, and any quote that sounds like it is deserves scrutiny.
Signs your pool needs resurfacing
Interior finishes fail gradually, so the decision is rarely urgent — but there is a point past which patching costs more than replacing.
- The surface feels rough underfoot. The single most common trigger. As plaster erodes, the aggregate beneath is exposed and the surface turns abrasive enough to scrape feet and swimsuits.
- Staining that will not come off. Once the finish is porous, minerals and organics penetrate rather than sit on the surface. Acid washing buys time but removes material each pass.
- Visible aggregate or bare patches. Grey or brown patches where the finish has worn through entirely.
- Spreading cracks or hollow spots. Tap the surface — a hollow sound means the finish has delaminated from the shell beneath it.
- Rising chemical consumption. A degraded, porous surface both harbours algae and consumes sanitiser faster than a sound one.
- The finish is simply old. White plaster generally lasts 7–12 years, quartz 10–15, pebble 15–20. Past that window, plan for it.
Choosing a finish
This is the decision worth spending time on. It sets the appearance, the texture underfoot, and how soon you will be doing this again.
The important arithmetic: every resurfacing job carries the same drain, chip-out, refill and start-up cost regardless of which finish goes in. So the cheapest material does not produce a proportionally cheaper project — and because white plaster needs replacing roughly twice in the time pebble lasts once, it usually loses over a twenty-year horizon.
| Finish | Installed | Service life | Trade-off |
|---|---|---|---|
| White plaster | $6.50–$9.50 / sq ft | 7–12 years | Cheapest upfront; stains and etches most readily |
| Quartz aggregate | $9–$13 / sq ft | 10–15 years | Harder and more stain-resistant; stays smooth underfoot |
| Pebble aggregate | $12–$18 / sq ft | 15–20 years | Longest practical life; noticeably rougher texture |
| Polished / glass bead | $18–$28 / sq ft | 15–25 years | Best appearance; most sensitive to installer skill |
Repair or resurface?
Localized damage can be spot-repaired, and sometimes should be. A patch is a few hundred dollars against several thousand, and if the finish is otherwise sound with years of life left, patching is the right answer even though the repair will not colour-match perfectly.
The calculus flips when damage is widespread. Patching does nothing for the surrounding finish, so on a surface that is broadly worn you are paying repeatedly to postpone the same project. A workable rule: once repairs approach a third of the cost of resurfacing, resurface.
What affects the price
- Interior surface area. Floor plus walls, not the pool footprint. Depth matters as much as length, which is why deep-end pools cost more than their surface dimensions suggest.
- Finish material. Roughly a four-fold spread per square foot between white plaster and a polished finish.
- Condition of the shell. Structural cracks, delamination and exposed rebar are invisible until the pool is drained. This is the leading source of change orders.
- How the old finish comes off. A shell that has been resurfaced several times may carry multiple layers, and removing them costs more than a single clean chip-out.
- Access. If a bobcat cannot reach the yard, debris leaves by wheelbarrow and labour hours climb.
- Region. Labour and permitting vary enough between metros to move the same scope by a quarter or more.
How the job runs
Two to four weeks from drain to swimming is typical for a straightforward resurfacing. Structural repair, deck work or permits extend it.
- Drain. One day. In high-water-table regions the crew checks groundwater first — an empty shell can float.
- Chip-out and preparation. Two to four days. The old finish is removed and the shell is sounded for hollow spots. Surprises appear here.
- Repairs and tile work. Two to five days if cracks need attention or tile and coping are in scope.
- Finish application. One day. It is applied in a single continuous pour and cannot be paused, which is why a large crew arrives at once.
- Fill and start-up. One to two days to fill, then a start-up period of daily brushing and careful chemistry. Skipping this damages a brand-new surface.
Worth doing at the same time
The pool is drained and a crew is on site. Anything requiring either of those conditions is dramatically cheaper now than later.
Waterline tile
New finish against scaled old tile looks unfinished, and tile is far cheaper to set into an empty pool. The most common companion by a wide margin.
Coping
Worth including if it is cracked or loose. Replacing it later usually means cutting into the deck edge.
LED lighting
Swapping fixtures in an empty pool avoids a diver or a second drain. $450–$1,200 per fixture installed.
Equipment
The pad is accessible and the pool is already down. A failing pump or an aging heater is cheapest to address now.
What this project needs measured
Measurements are only requested when they change the price of the work you selected. Everything below is collected inside the estimator — you can enter dimensions you already know or measure as you go.
Required
Pool interior surface area
Resurfacing and finish work are priced by the square footage of the interior shell.
Only if it applies
Attached spa
An attached spa is a separate surface and is usually quoted as its own line item.
Only if it applies
Pool perimeter (linear feet)
Tile and coping are priced by the linear foot around the pool edge.

Combining these while the pool is already drained and staged is usually cheaper than returning for them later. You can add or remove any of them inside the estimator.

Frequently asked questions
- How long does pool resurfacing take?
- Two to four weeks from drain to swimming for a straightforward job. Adding structural repair, tile, coping or deck work commonly pushes it to five or six weeks, and permits can add more.
- How much does it cost to resurface a pool?
- For an average 15 × 30 ft pool — roughly 945 square feet of interior surface — expect about $8,000–$12,000 in white plaster and $14,000–$22,000 in pebble, including the drain, chip-out, refill and start-up. Your own figure depends on size, finish, shell condition and region.
- How often does a pool need resurfacing?
- It depends on the finish. White plaster typically lasts 7–12 years, quartz 10–15, and pebble 15–20. Water chemistry is the biggest variable — a well-maintained plaster finish can outlast a neglected pebble one.
- Can I resurface a pool without draining it?
- No. The old finish has to be removed and the new one applied to a dry shell. Any product marketed as a no-drain resurfacing is a coating over the existing surface, and it will not last like a proper finish.
- What is the difference between resurfacing and replastering?
- Replastering is one kind of resurfacing — specifically, applying new plaster. Resurfacing is the umbrella term covering any replacement finish, including quartz and pebble. Contractors often use them interchangeably, so confirm which material a quote actually covers.
- Can I swim as soon as it is filled?
- Not immediately. The finish cures underwater and needs a start-up period of daily brushing and controlled chemistry, typically running a few weeks. Your contractor should tell you when the pool is ready and what to do in the meantime.
