Choosing between a flagstone vs paver patio isn’t just about looks—it’s about how the space will serve your lifestyle for years to come. Homeowners across St. Louis want something that’s durable, beautiful, and adds value. But which option is right for your backyard?
We’re breaking down the pros and cons, the costs, and the installation differences between flagstone and pavers, so you can make a confident decision before calling a patio installer.
Flagstone vs Paver Patio: Which is Right for Your Outdoor Space?
Flagstone patios and paver patios both offer lasting beauty, but they deliver very different experiences underfoot and in your landscape design.
Flagstone patios:
- Natural stone look that blends into more rustic or organic landscapes
- Irregular shapes and earthy tones give each patio a one-of-a-kind appearance
- Cooler to the touch in hot weather due to the stone’s properties
Paver patios:
- Manufactured from concrete, brick, or natural stone for consistent shape and color
- Offer crisp, clean lines for modern or traditional designs
- Easy to pattern and repeat for a sleek, organized look
In St. Louis, we see flagstone used often in shaded backyards or woodsy areas where a natural look works best. Pavers are more popular in open yards or paired with fire pits, outdoor kitchens, and retaining walls, where symmetry and structured layouts are key.
Bottom line: If you want a patio that feels like it’s always been part of your yard, flagstone is a solid choice. If you’re leaning toward a modern, low-maintenance space, pavers offer more design control and customization.
Understanding Flagstone Patio Costs: What to Expect in St. Louis
Flagstone patio cost varies, and in the St. Louis area, several factors play into what you’ll pay:
- Material type: Pennsylvania Bluestone, Arizona flagstone, and local quarried stones range from $3 – $10 per square foot just for materials.
- Labor: Because flagstone installation involves fitting irregular pieces together by hand, labor runs higher, often $15 – $30 per square foot.
- Base preparation: Grading, drainage, and gravel or mortar base can add several dollars per square foot.
- Design complexity: Tight curves, elevation changes, or steps increase labor time and cost.
Typical range in St. Louis: $25 to $40 per square foot installed
A small 200-square-foot flagstone patio could start around $5,000 and climb past $8,000 depending on finishes and site conditions.
What Does a Paver Patio Cost in 2025?
Paver patios are often more budget-friendly to install, at least in terms of labor, and the cost differences typically boil down to:
- Material choice:
- Standard concrete pavers: $2–$6 per square foot
- Brick pavers: $4–$8 per square foot
- Natural stone pavers: $7–$12 per square foot
- Installation: Laying uniform pavers is quicker and less labor-intensive than flagstone, with costs around $10–$20 per square foot for labor and base prep.
- Customization: Intricate patterns like herringbone or borders will cost more due to cutting and extra time.
Typical range in St. Louis: $18 to $30 per square foot installed
That means a mid-sized 300-square-foot paver patio could cost anywhere from $5,400 to $9,000, depending on the materials and design.
Flagstone vs paver patio cost takeaway: Flagstone typically costs more because of the labor involved, but for some homeowners, the natural finish is worth the extra investment.
Installation Differences: Patio Flagstone vs. Paver Projects
When it comes to building your patio, there are some key differences in how flagstone and pavers are installed.
Flagstone Patio Installation
- Involves selecting and arranging irregular stone pieces like a jigsaw puzzle
- May be set in sand, stone dust, or mortar depending on site needs
- Requires leveling each piece manually for a walkable surface
- Joints are often filled with stone dust, gravel, or mortar grout
Paver Patio Installation
- Involves laying consistent units in a predetermined pattern
- Installed over a compacted base with sand joints
- Easier to level, with quicker turnaround time
- Can be sealed for enhanced durability and appearance
Paver patios are often installed faster and with fewer site complications. Flagstone patios take more time but deliver a classic look that’s tough to replicate with manufactured pavers.
What to Look for When Hiring the Right Patio Installer in St. Louis
Whether you’re leaning toward flagstone or pavers, the success of your patio comes down to the quality of installation and which paver or flagstone patio contractor you choose.
Here’s what to look for when searching for a flagstone or patio paver contractor:
- Experience with both materials: Ask to see recent projects. Flagstone takes a different skill set than paver work.
- Clear design and layout planning: Look for 3D renderings or at least a scaled sketch.
- Knowledge of drainage: Poor grading ruins patios; your installer should understand water flow.
- Transparent pricing: Quotes should include prep work, material cost, labor, and optional features like sealing or lighting.
- Warranties and timelines: Good contractors stand behind their work and don’t leave you hanging halfway through.
Avoid anyone who refuses to walk you through their process or doesn’t offer references from past clients.
