Resurfacing is the anchor job: a standard white plaster replaster in New Hampshire typically runs $6,000–$11,500, while pebble and quartz finishes run $9,000–$20,500. Everything else stacks on top of that:
| Job | Typical New Hampshire price |
|---|---|
| Replaster (white plaster) | $6,000–$11,500 |
| Pebble or quartz finish | $9,000–$20,500 |
| Waterline tile | $2,900–$9,200 |
| Coping replacement | $3,400–$10,400 |
| Deck resurfacing | $4,500–$14,000 |
| Equipment upgrade (pump, filter, heater, automation) | $3,500–$11,500 |
| Add an attached spa | $17,500–$40,500 |
| Full remodel (finish, tile, coping, deck, equipment) | $17,500–$69,000+ |
New Hampshire 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.

Granite State means it: ledge and boulders make excavation the big unknown, so a written rock clause protects you. Frost-depth plumbing, freeze-thaw decking, and generous slope drainage are standard specs, and wooded lots add tree work to plenty of budgets. Vinyl liner dominates, fiberglass is growing fast for quick installs, and heated pools with automatic covers make the short season worth it. Simple rectangles with big deck space fit the lake-house entertaining style.
The largest listed markets are Nashua (50 companies), Manchester (41 companies).
Ask for nearby resurfacing jobs that are several years old, not just fresh ones. Confirm licensing where New Hampshire 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. New Hampshire has no general statewide contractor license, so vetting is on you — insurance certificates, references, and recent local addresses matter more here. Pool permits and residential-code barrier requirements (fencing, self-latching gates) run through your town's building department.
A standard white plaster replaster in New Hampshire, NH typically runs $6,000–$11,500; quartz and pebble finishes run $9,000–$20,500. Waterline tile adds $2,900–$9,200 and new coping $3,400–$10,400. A full remodel that also updates the deck and equipment runs $17,500–$69,000+. New Hampshire 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 New Hampshire 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. Mid-June through early September unheated; heaters realistically buy a month more. Winters are long and hard-freezing, so full winterization with a snow-rated cover is the standard of care.

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.
