Calcium Scale Removal Cost for Nevada Pools: Las Vegas and Reno Prices for 2026

Calcium scale removal for Nevada pools costs about $250 to $900 for tile and more for full treatment. See why Lake Mead water builds scale and how to stop it.

Calcium Scale Removal Cost for Nevada Pools: Las Vegas and Reno Prices for 2026

Every pool in Las Vegas fills from the same place. Water from Lake Mead runs through the Southern Nevada Water Authority system and into backyards from Summerlin to Henderson, and it carries a heavy load of dissolved calcium. Add 110°F summer days that boil off water and a weekly top-off that brings in more minerals, and a white crust along the tile line is almost guaranteed.

Most Nevada homeowners pay roughly $250 to $900 to remove calcium scale from the waterline tile, and $400 to $2,500 or more for scale treatment across the whole pool. The low end covers a quick tile cleaning on a small pool. The high end covers bead blasting, acid washing, or a full drain and refill on pools that have gone years without attention.

Why Lake Mead Water Builds Scale So Fast

Las Vegas tap water usually tests somewhere around 250 to 300 ppm of calcium hardness, or roughly 15 to 18 grains per gallon. Water from the Colorado River picks up minerals as it travels through the Southwest. By the time it reaches your hose, it is already near the upper limit of what a pool can handle.

Evaporation does the rest. A Las Vegas pool can lose a quarter to half an inch of water a day in June and July. The water leaves, but the calcium stays, so every top-off stacks more mineral into the same volume.

After two or three summers, calcium hardness in many valley pools climbs past 600 or 800 ppm. Total dissolved solids rise too. At those levels, the water cannot hold any more calcium, and it starts dropping out onto the tile, the plaster, and the inside of your heater and salt cell.

The Two Types of Scale You Will See

Calcium carbonate scale is white or light gray and fairly soft. It flakes off with a pumice stone or a scale remover, and it forms quickly when pH runs high. Most fresh scale on Henderson and North Las Vegas pools is this kind.

Calcium silicate scale is harder and darker. It builds slowly over years and bonds to the tile glaze like stone. Chemical cleaners barely touch it, which is why many older Las Vegas pools need bead blasting to get the tile clean.

A good technician will scratch the deposit and test it with a drop of acid before quoting. Carbonate scale fizzes. Silicate scale does not, and it costs more to remove.

What Each Removal Method Costs

The method you need depends on how thick the scale is and what type it is. Here are the most common options in southern and northern Nevada, with approximate prices for a typical residential pool:

• Hand cleaning with pumice or scale remover: $150 to $400 for light carbonate scale on the tile line
• Glass bead or media blasting of the waterline tile: $350 to $900 for most pools, higher for long tile runs or raised walls
• Chemical scale treatment and sequestrant program: $100 to $300 to start, plus monthly product
• Acid wash of a drained plaster pool: $500 to $1,200 including drain and refill labor
• Full drain and refill to reset hardness: $300 to $800 in labor, plus the cost of water

Bead blasting is the most popular choice in Las Vegas for heavy tile scale. Crews lower the water a few inches and blast the tile with fine glass beads or a soft media that removes the crust without scratching the glaze. Most jobs take two to four hours.

Bead Blasting Up Close

Prices for bead blasting usually depend on linear feet of tile. A 40 foot pool with a standard 6 inch tile band falls near the low end. Pools with raised spa walls, water features, or a vanishing edge can double the price.

Ask the company what media they use. Glass bead is common, but some tile finishes do better with a softer media like walnut shell or a sodium bicarbonate blend. A crew that uses the wrong grit can dull glossy tile.

When a Drain and Refill Makes Sense

Cleaning the tile removes scale you can see, but it does not fix water that keeps making more. If your calcium hardness is over 800 ppm or total dissolved solids pass about 3,000 ppm, many Las Vegas pool pros recommend draining. Most valley pools need this every two to four years.

Draining in the summer is risky in Nevada. Plaster exposed to direct desert sun can crack, and some pools can shift if groundwater is present. Most companies schedule drains from October through April.

Check with the Southern Nevada Water Authority or your local utility for any rules on where drained water can go. Many homeowners in Clark County drain into the sewer cleanout, not the street.

How the Costs Add Up on a Typical Valley Pool

Picture a 15,000 gallon plaster pool in Henderson that was built in the early 2000s. The tile has a thick white band, the water tests near 900 ppm calcium, and the salt cell needs cleaning every few weeks. This is a common situation across the valley.

A sensible plan for that pool might start with a winter drain and refill for about $400 to $700, plus roughly $60 to $120 in water. While the pool is empty, the crew can acid wash the plaster for another $300 to $600 and clean the tile by hand or with media. Once refilled, the owner starts a sequestrant program and gets a fresh water reading.

All in, that owner might spend $1,000 to $1,800 to reset the pool. That sounds like a lot until you compare it with a new heater or a full replaster, which can cost several times more. Spreading the work across a slow season also tends to get better pricing.

Ask for a Water Test Before Any Quote

A pool company quoting scale removal without testing your water is guessing. Calcium hardness, pH, alkalinity, and total dissolved solids tell you whether cleaning the tile will hold or whether the scale will come right back. Most Las Vegas service companies test for free or for a small fee.

Keep a copy of the numbers. Comparing readings from one season to the next shows how fast your pool is building minerals.

Reno and Northern Nevada

Reno and Sparks pull most of their water from the Truckee River, which is softer than Lake Mead water. Pools in northern Nevada still build scale, but more slowly. Many Reno owners can go five or more years between drains.

The shorter season helps too. Pools in Reno, Carson City, and Minden close in fall, so they lose less water to evaporation over a year. Scale problems there tend to show up on heaters and salt cells before they show up on the tile.

Northern Nevada scale removal often costs a bit more per visit because there are fewer specialized bead blasting crews. Expect prices about 10 to 20 percent above Las Vegas for the same tile work.

Scale Inside Equipment Costs More Than Scale on Tile

The tile line is the scale you see. The scale you do not see sits inside heat exchangers and salt cells, and it shortens the life of expensive equipment. A heater with scaled tubes runs longer to warm the pool and can fail years early.

Salt cell cleaning usually costs $50 to $150 per visit if a service company does it. Many Las Vegas techs clean cells every two to three months during summer. A replacement cell often runs $500 to $1,000.

Heat pump and gas heater descaling ranges from about $150 to $400. If the heat exchanger is already damaged, replacement can cost $1,000 or more.

Keeping Scale From Coming Back

Water balance is the cheapest defense. Keep pH between about 7.2 and 7.6 in Nevada, since high pH pushes calcium out of solution. Total alkalinity on the lower side of normal also helps.

Many valley pool companies use a scale inhibitor or sequestrant on a regular schedule. It binds calcium so it stays in the water longer. Combined with a weekly tile brushing, it can stretch the time between bead blasting jobs from one year to two or three.

Covers help in a Nevada climate. A solar or automatic cover cuts evaporation by a large margin, which means fewer top-offs and slower mineral buildup. Owners in Summerlin and Henderson often see the payoff within one summer.

You can find crews who handle tile cleaning and water balance in the Nevada pool service directory. For more desert pool care advice, see our other pool and home care articles.

Nevada Calcium Scale FAQ

How often should a Las Vegas pool have its tile bead blasted?

Most valley pools need it every one to two years without a scale prevention routine. With regular pH control and a sequestrant, many owners stretch it to every three years. Pools with heavy splash or waterfalls usually need it more often.

Can I remove calcium scale myself?

Light carbonate scale often comes off with a pumice stone and a mild scale remover. Hard silicate scale on Las Vegas tile usually needs bead blasting. Scrubbing too hard with the wrong tool can scratch tile and leave a dull band.

Does a water softener help a Nevada pool?

A whole-house softener does not usually feed the pool fill line. Some owners use a portable softening or reverse osmosis service, which can run $400 to $900 per pool. It lowers hardness without draining as much water.

Is scale bad for my pool or just ugly?

It is both. Heavy scale makes plaster rough, clogs filters, and damages heaters and salt cells. Removing it early costs less than replacing equipment later.
