Pool Acid Wash & Restoration Pricing

Here’s what pool restoration actually costs in Scottsdale, in plain numbers. Most competitors hide behind “call for a quote.” We don’t. A standard pool acid wash runs $400–$800; larger and luxury Scottsdale and Paradise Valley pools run $700–$1,200 or more. Green-pool drain-and-cleans are usually $250–$600, and tile or calcium work runs $200–$500. Send photos, get a flat number.

Every quote is flat and up-front. The only cost that isn’t ours to set is the refill water, which goes on your city meter — more on that below.

What actually moves the price

Two pools that look similar from a phone photo can cost very different amounts. Here’s what we’re actually looking at when we build your quote:

• Pool size. Acid, labor, and time all scale with surface area — perimeter and square footage. A 10,000-gallon backyard pool and a 40,000-gallon Paradise Valley estate pool are not the same job. This is the single biggest factor.
• Stain severity and type. Light calcium dusting is quick. Heavy calcium scale, iron or copper metal stains, sunscreen mottling, or a black-algae green pool each take more passes and more product. A neglected snowbird pool that’s been green for months sits at the top of its range.
• Surface type. Standard white plaster, quartz, and Pebble Tec all behave differently under acid. Premium pebble finishes on luxury pools call for a lighter, more careful touch — which is a feature, not an upcharge, but it does affect how we approach the job.
• Access and drain path. A pool where we can drain cleanly to a nearby sewer clean-out is simpler than one requiring long runs or extra pumping. Estate pools with tricky access take a bit more setup.

What each service actually gets you

To make the numbers concrete, here’s what’s included in each job so you can see where the money goes:

• Acid wash ($400–$1,200+): full drain, a careful section-by-section acid wash of the bare plaster or pebble, neutralizing and responsible disposal of the waste, a chlorine bath, refill, and a rebalanced chemistry hand-off. This is the whole restoration, not a partial.
• Green pool cleanup ($250–$600): pumping out the dead water, removing debris, scrubbing the surface, a chlorine bath so it doesn’t re-green, and a fresh refill with balanced chemistry.
• Calcium & scale removal ($200–$500): bead blasting heavy buildup or acid-treating lighter scale, containment and cleanup of the spent media, usually with no drain required.
• Pool tile cleaning ($200–$500): waterline tile band restored by bead blasting, pool stays full, no refill cost.
• Drain & clean ($200–$450): drain, pressure wash the shell, clear debris, refill and rebalance — no acid, for pools where the water is shot but the plaster’s fine.
• Resurfacing prep (quoted per job): chip-out, calcium removal, and acid etch so a new plaster or Pebble finish bonds correctly.

How our pricing compares in Scottsdale

You’ll see acid-wash numbers around town from roughly $250 on a small pool up past $1,500 on a large one. Our ranges sit squarely in that reality — the difference is that we tell you where your pool lands before you commit, instead of quoting a lowball figure and adding to it on site. On the luxury end, Scottsdale and Paradise Valley estate pools genuinely cost more than a compact backyard pool, and any quote that ignores that is one that’ll grow once the crew shows up. We’d rather give you the honest number now.

The refill water cost (yours, not ours)

When we acid wash or drain-and-clean, the pool comes back empty and has to be refilled with city water. That water is on your meter — we don’t mark it up or profit from it. What we do is tell you roughly how many gallons you’re looking at so the water bill isn’t a shock.

A typical residential Scottsdale pool holds 10,000–25,000 gallons. Large estate pools in Paradise Valley and the Scottsdale foothills can hold 30,000–50,000+. Depending on your tier and city rates, a full refill commonly adds a modest but real amount to that billing cycle — plan for it. If you’re on a tight water budget, sometimes a targeted tile and calcium cleaning or partial drain gets you most of the result without emptying the whole pool; we’ll tell you honestly when that’s an option.

When acid washing is NOT the right spend

We’ll say this plainly because it’s the honest thing and most companies won’t: an acid wash removes a thin layer of plaster every time, so a surface can only take so many over its life. If your plaster is already thin, deeply mottled, showing exposed aggregate (little pebbles or a rough gray patchwork), or if it’s been acid washed several times already, another wash is throwing good money after bad. At that point a resurface — new plaster or a Pebble finish — is the smarter investment, and we’ll prep it properly. A full resurface is a bigger project (Pebble finishes in the Valley commonly run five figures), but it resets the clock for 15–25 years instead of buying you another year or two.

Bundling work while the pool is empty

If your pool needs to be drained anyway — for an acid wash or green-pool cleanup — it’s the cheapest time to knock out anything else the surface needs. Removing heavy calcium from the plaster, restoring the waterline tile, or doing resurfacing prep all happen more efficiently on an empty pool, and you pay one refill instead of two. If we’re already draining, ask what else makes sense to do in the same visit — it usually saves money versus separate trips and separate refills down the road. We’ll lay out the options honestly rather than automatically bundling in work you don’t need.

How to get a flat quote

1. Snap photos of the whole pool, the waterline tile band, and any bad staining.
2. Note the rough dimensions and depth if you know them.
3. Send them over — we reply with a flat, up-front price.

No pressure, no sales visit for most jobs. Not sure which service you need? Start with the pool acid wash or green pool cleanup pages, or read the full FAQ. And if the honest answer is that your pool needs less than you expected — a tile cleaning instead of a full wash, or a drain-and-clean instead of acid — we’ll tell you that, because a fair quote today is what earns the next job. We serve Scottsdale, Paradise Valley, Fountain Hills, Tempe, and Cave Creek.
