Pool Deck Repair Cost
Deck repairs run from about $8 per linear foot for crack filling to $2,200 to lift a settled section. The useful question is not what each costs, but at what point they add up to more than resurfacing.
Typical national range
$400–$3,500
Typical single-defect repair on a residential pool deck — crack filling, spall patching or lifting one settled section. Multi-defect decks run considerably higher.
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 deck area
Deck work is priced by square footage, and the condition of the existing slab changes the preparation cost.
Only if it applies
Pool perimeter (linear feet)
Tile and coping are priced by the linear foot around the pool edge.
Cost by problem
| Problem | Method | Cost | Durability |
|---|---|---|---|
| Hairline cracks | Clean, fill, texture-match | $8–$16 / linear ft | Good — these are stable |
| Structural cracks | Rout and fill with flexible sealant | $15–$30 / linear ft | Only as good as the cause fix |
| Settled section | Slab-jacking with polyurethane foam | $600–$2,200 per section | Good if the sub-base is stabilised |
| Spalling | Grind, patch, resurface locally | $10–$20 / sq ft | Good — but patches are visible |
| Failed expansion joint | Clean out and replace joint material | $8–$14 / linear ft | Excellent, and prevents further damage |
| Trip hazard at a joint | Grind level or slab-jack | $200–$900 | Good |
When repair stops being the cheaper option
Repairs are targeted, so they are cheap when the targets are few. The arithmetic reverses quickly once several defects are in play — and a patchwork deck also looks worse than a uniformly resurfaced one.
| Situation | Repair cost | Better option |
|---|---|---|
| One crack, 12 ft | $100–$360 | Repair |
| Several cracks, 40 ft total | $320–$1,200 | Repair |
| Cracks plus a spalled area | $1,200–$3,000 | Repair, then plan resurfacing |
| Cracks, spalling and a settled section | $2,500–$5,500 | Resurface, at $3,600–$8,400 |
| Widespread cracking from movement | $4,000+ | Replace, at $7,200–$15,600 |
Fixing the cause costs more than fixing the symptom
This is the part of deck repair budgeting people miss. Filling a crack is cheap; stopping it recurring may not be.
| Cause | Correction | Cost |
|---|---|---|
| Poor surface drainage | Regrade or add drainage | $1,200–$6,000 |
| Sub-base voids | Compaction grouting | $800–$3,500 |
| Expansive soil movement | Drainage management and joint design | $1,500–$8,000 |
| A leaking pool or line | Leak detection and repair | $500–$4,000 |
| Tree roots | Root barrier or removal | $600–$3,000 |
How to read a PoolSavr estimate
- Step 1
Instant estimate
Based on your project selections and general pricing assumptions. Useful for deciding whether a project is realistic.
- Step 2
Measured estimate
Uses your pool, spa, or deck dimensions to price the work against the areas actually being resurfaced, tiled, or replaced.

Frequently asked questions
- How much does it cost to repair a cracked pool deck?
- Hairline crack filling runs $8–$16 per linear foot, and structural crack repair $15–$30. A 12-foot crack is therefore $100–$360. The larger question is whether the cause needs correcting, which can run into the thousands.
- How much does it cost to lift a sunken pool deck?
- Slab-jacking a settled section typically costs $600–$2,200 depending on area and lift required. It is far cheaper than replacement and works well provided the slab itself is intact and the sub-base gets stabilised.
- At what point should I resurface instead of repair?
- When repair quotes reach roughly half the cost of resurfacing. On a 600 sq ft deck that is around $2,000–$4,000 of repairs against $3,600–$8,400 to resurface — and resurfacing gives you a uniform surface rather than visible patches.
- Will repairs be visible?
- Usually yes. Patched concrete rarely matches surrounding weathered concrete in colour or texture, and the contrast softens only partially over time. If appearance is the main concern, resurfacing is the honest answer.
- Can I repair the deck myself?
- Crack filling with a proper concrete repair product is within reach for a competent DIYer, and expansion-joint replacement is straightforward. Slab-jacking, structural crack repair and anything involving drainage are not — those need equipment and diagnosis.
