Pool Acid Wash Cost
An acid wash runs $450–$1,100 for an average residential pool. It is worth comparing against resurfacing cost before committing, since a finish nearing the end of its life gets better value from a fresh surface.

Required
No measurement required
This project is diagnosed from symptoms and equipment details rather than dimensions.
What affects the price
- Pool size. More surface area to treat.
- Severity of scale or staining. Heavier buildup can need a stronger solution or a second pass.
- Whether draining is included. Some quotes separate the drain and refill from the wash itself.
- Access. How easily equipment and chemical containers reach the pool.
Acid wash against resurfacing

|---|---|

| Finish 7-12 years old, already washed once | Acid wash, but plan resurfacing |
| Finish already washed twice or more | Resurfacing |
| Surface is rough as well as dull | Resurfacing |

- Typically $450–$1,100 for an average residential pool, including draining. Confirm whether refill and chemical start-up are part of the quote.
- Is acid washing cheaper than resurfacing?
- Considerably, but it is not a substitute once a finish is worn out — it only strips a thin surface layer. Compare against your finish's age and prior wash history before choosing it as the fix.
