How much does a bluestone patio cost in the Hamptons?

The per-square-foot math

Surface	Installed, per sq ft (2026)
Bluestone, Long Island	$20–50 (contractor sources: $20–40 and $30–50); national blend $16–38
Concrete pavers, Long Island	$20–35
Travertine, Long Island	$25–45
Porcelain pavers, Long Island	$30–50
Limestone, granite, marble, Long Island	$40–65
Clay brick	$10–20

Multiply by the area and add the extras: removing an old slab ($2–6 per sq ft), grading and base ($1.50–4, plus $3–8 in heavy clay), a French drain around the terrace ($25–40 per linear foot), steps ($900–2,000 for a typical bluestone staircase), a seat wall ($20–60 per sq ft of face dry-stacked). A 500 sq ft thermal bluestone terrace with steps and a drain lands in the $15,000–30,000 range on the South Fork.

What pushes a Hamptons quote up

• The base. Site preparation is about 90% of the labor on a patio job. Fast-draining outwash sand south of the highway, till with clay lenses north of it, and a water table 2–8 feet down near the bays each change the base depth and drainage.
• Thermal, thickness and grade. Thermal costs about $3 more per square foot than natural cleft in material; 1½- to 2-inch stone for dry-setting costs $2–6 more than 1-inch; blue-blue costs more than full-color.
• Pattern. A dimensional ashlar pattern cuts and fits faster than an irregular flagstone field; a curved edge or an inlay costs hours.
• Access and hours. A village lot with no place to drop a pallet, and summer work-hour limits (East Hampton Village: weekdays 8am–6pm and Saturdays noon–4pm from May 15 to September 15), stretch the schedule.
• Coverage and permits. Patios count toward lot coverage (20% of the lot in East Hampton Village; 14% plus 1,500 sq ft in Southampton Village), and a terrace within 100–150 feet of a wetland is a permit application.

What a fair quote looks like

It states the stone (thermal or cleft, thickness, grade, pattern), the base depth and material, whether the stone is dry-set or mortared, the joint fill, the edging, the drainage, the demolition and disposal, the steps and walls as separate lines, and who handles the zoning check. A single number per square foot on a business card is not a quote.

Timeline

A 400–600 sq ft patio takes a professional crew 4–5 days, up to a week on rocky or clay ground. The calendar is set by the season (spring and early fall are best), the village hours, and any permit.
