Resurfacing is the anchor job: a standard white plaster replaster in Montana typically runs $5,500–$11,000, while pebble and quartz finishes run $9,000–$20,000. Everything else stacks on top of that:
| Job | Typical Montana price |
|---|---|
| Replaster (white plaster) | $5,500–$11,000 |
| Pebble or quartz finish | $9,000–$20,000 |
| Waterline tile | $2,800–$8,800 |
| Coping replacement | $3,300–$9,900 |
| Deck resurfacing | $4,500–$13,000 |
| Equipment upgrade (pump, filter, heater, automation) | $3,500–$11,000 |
| Add an attached spa | $16,500–$38,500 |
| Full remodel (finish, tile, coping, deck, equipment) | $16,500–$66,000+ |
Montana pricing is above the national baseline used for these estimates, mainly on labor and permitting. Plaster has a finite life — 10–15 years for white plaster, 15–20+ for pebble — so a resurfacing quote is often the moment to price tile, coping and equipment in the same drain.
Tile, coping, LED lights, a tanning ledge or an attached spa cost far less during a resurfacing than as a separate job later.

Rocky ground and river cobble make excavation the wildcard — get rock language in writing — and frost-depth plumbing plus robust winterization design are standard. Bozeman-area builds often pair pools with significant landscape and terrace work. Fiberglass and vinyl fit the install window; heated pools with automatic covers and mountain-facing terraces define the look. Integrated hot tubs are practically standard.
The largest listed markets are Missoula (5 companies).
Ask for nearby resurfacing jobs that are several years old, not just fresh ones. Confirm licensing where Montana requires it, insurance, and who holds the finish warranty. Compare at least three itemized bids against the same scope: finish, tile, coping, deck, equipment and startup. Montana registers construction contractors at the state level — verify registration and insurance. Pool permits and residential-code barrier requirements run through your city or county building office; resort-town design review boards can add a step in places like Big Sky and Whitefish.
A standard white plaster replaster in Montana, MT typically runs $5,500–$11,000; quartz and pebble finishes run $9,000–$20,000. Waterline tile adds $2,800–$8,800 and new coping $3,300–$9,900. A full remodel that also updates the deck and equipment runs $16,500–$66,000+. Montana pricing is above the national baseline used for these estimates, mainly on labor and permitting; get itemized bids from at least three companies for your pool's size and condition.
White plaster typically lasts 10–15 years; quartz and pebble finishes 15–20 or more with balanced water. Roughing, staining that no longer cleans, exposed aggregate, hollow spots and rust marks from the rebar are the signs the finish is at the end of its life. Etching accelerates when pH and calcium hardness run low, so a consistent water-care routine is the cheapest way to delay the next resurfacing.
A straightforward resurfacing usually keeps the pool down for one to two weeks: drain, prep, finish, cure and fill, followed by a 28-day startup brushing routine. Adding tile, coping and deck work extends that to three to six weeks, and equipment or structural changes can push a full renovation past two months. Most crews schedule remodels for the shoulder seasons so the pool is ready when the season starts.
Resurface if the shell, tile, coping and equipment are sound and you mostly dislike the finish. Remodel when several systems are at the end of their life at once — a drained pool is the cheapest moment to replace tile and coping, add a tanning ledge or spa, move to LED lights, or install a variable-speed pump and automation. Ask each contractor to price the resurfacing alone and the bundled options separately so you can see the marginal cost of each upgrade.
The outdoor season in Montana runs mid-June through early September — about 3 months unheated. A full professional winterization each fall protects plumbing and equipment through the freeze, and spring openings cluster into the same few weeks. The unheated season runs mid-June through early September, with cool nights even in July. A heater materially extends use, and winters are long and hard-freezing statewide.

Plaster and pebble finishes normally carry a manufacturer material warranty (often 5–10 years, sometimes limited or prorated) plus the installer's workmanship warranty (commonly 1–5 years) covering delamination, spot etching from improper startup and bond failure. Tile, coping and equipment carry their own terms. Read what voids coverage — most exclude damage from unbalanced water — and keep your startup and water-test records.
