Homeowners across the country love the look of natural flagstone, and a 500 square foot patio hits the sweet spot for most backyards. But how much should you budget? At CountBricks, we analyze thousands of live material prices every day and convert them into easy-to-understand numbers inside our AI estimate generator. Below, we break down what you can expect to spend, why costs vary, and how CountBricks.com/services can lock in reliable figures long before the first stone is set.
Most residential clients see the total cost for a 500 square foot flagstone patio land between $13,500 and $24,000. That package price assumes professional installation and includes material, labor, equipment, haul-off, and typical site prep. Using CountBricks voice estimating, you’ll receive a real-time range and a line-item breakout so you can fine-tune finishes without nasty change-order surprises.

A San Antonio homeowner recently asked CountBricks for a 500 square foot flagstone patio behind a new build. Within a five-minute voice call our system captured slope notes, irrigation lines to relocate, and the client’s wish for a fire pit hub.

• Material split: 42 % Oklahoma Blue flagstone, 16 % base aggregate, 3 % polymeric sand

1. Early soil probe revealed expansive clay. We added geo-fabric and an extra base lift for $540—far less than future heave repairs.
2. Our takeoff flagged 24 linear feet of seating wall. By shifting to dry-stack stone from the same quarry, we saved the client $1,200 in mortar labor.
3. A web portal change request swapped the standard fire pit for a custom steel insert. CountBricks updated the schedule and purchase orders in under two minutes.
The project finished two days ahead of schedule with a zero-punch-list turnover. Post-construction drone photos, hosted at CountBricks.com/portfolio, showcase the seamless blend between patio and surrounding xeriscape. Most importantly, the homeowner gained a transparent record of every cost decision along the way.
