What this patio estimate includes

The material-only result estimates stone, four inches of compacted base, and one inch of bedding sand. The installed planning result adds only the editable labor allowance. Both exclude delivery, excavation, drainage, edge restraint, tools, disposal, permits, and tax. Confirm depth and ordering allowance with your supplier or installer.

Current cost context

Angi’s 2026 guide places installed flagstone patios broadly around $15–$30 per square foot. Its separate flagstone guide reports stone alone around $2–$6 per square foot. HomeAdvisor reports average bluestone paver material pricing around $5–$12 per square foot. Those are broad planning ranges, not local bids.

A 2026 regional supplier price book lists many patio flagstones around $447–$780 per ton, depending on thickness and grade, with common coverage around 70–110 square feet per ton. Freight and local geology can move those numbers substantially.

Why your actual quote can differ

  • • Excavation and base condition
  • • Drainage and site access
  • • Stone thickness, grade, and freight
  • • Mortar-set versus dry-laid installation
  • • Pattern, cuts, edges, and obstacles
  • • Local labor and disposal costs

Frequently asked questions

What does the material-only estimate include?

It includes the selected stone, base gravel, and bedding sand. It does not include delivery, excavation, drainage, edging, tools, disposal, permits, tax, or labor.

What does the installed planning estimate include?

It adds your labor allowance per square foot to the material-only result. It is not a contractor quote and does not add the excluded site costs automatically.

Why can local flagstone patio cost differ?

Stone thickness, freight, access, excavation, drainage, base condition, pattern, cuts, labor, disposal, and local requirements can all change the final price. Replace the defaults with supplier and installer quotes.

Do I have to request a quote?

No. The complete material estimate and every planning link work without submitting contact information.

Does Hardscape Genius install patios?

No. Hardscape Genius provides actual-stone layout software and a design service. Quote requests are manually reviewed before they may be shared with an independent approved installer or stone yard.

Is a partner match guaranteed?

No. We will not claim a match exists until an approved partner confirms that they serve the project location and type.
