Step-by-Step Flagstone Patio Installation by Professionals
Excavation and Base Preparation
To ensure a long-lasting and beautiful flagstone patio, professional preparation of the site is essential. Here’s how experts at Steve’s Services Landscape Company handle it:
- Depth Calculation:
- Precision Planning: Professionals determine the total depth required, typically around 8-9 inches. This includes 4 inches for the base material, 2 inches for the sand layer, and the thickness of the flagstones.
- Excavation:
- Safety First: Our team uses the right equipment and safety gear to excavate the area, ensuring a consistent depth for a level patio.
- Drainage:
- Expert Slope Design: We ensure the base slopes away from your home to prevent water pooling, with a recommended slope of 1/2-inch for every 4 to 8 feet.
- Compacting Base:
- Solid Foundation: Crushed limestone or gravel is added to the excavated area and compacted using professional-grade equipment, providing a stable base to prevent future shifting.
- Adding Sand:
- Smooth and Level: A 2-inch layer of builder’s sand is spread over the compacted base, raked smooth, and checked for levelness by our skilled team.
Laying the Flagstones
With the base expertly prepared, our professionals lay the flagstones with precision and care.
- Pattern Layout:
- Visual Planning: Stones are laid out in the desired pattern without mortar or sand to visualize the final look and minimize cutting.
- Setting Stones:
- Professional Placement: Starting from the perimeter inward, each stone is placed and gently tapped into place with a rubber mallet to ensure they sit firmly on the sand.
- Leveling:
- Precision Check: Our team uses levels to ensure each stone is flush with the others, adjusting by adding or removing sand as needed.
- Cutting Stones:
- Expert Cutting: If necessary, stones are trimmed for a perfect fit using professional tools, with safety measures in place.
Filling the Gaps
Once the stones are in place, our professionals fill the gaps to ensure stability and aesthetics.
- Builder’s Sand or Polymer Sand:
- Professional Choice: Gaps are filled with builder’s sand for a natural look or polymer sand for added stability, which hardens when wet to reduce weed growth.
- Moss or Groundcover:
- Natural Enhancement: For a lush, rustic look, our team can plant moss or groundcover between the stones, adding character and aiding in erosion control.
- Final Touches:
- Secure and Finish: Sand is swept into all the joints and lightly sprayed with water to settle it. This process is repeated if necessary to ensure the stones are secure.

Cost of Flagstone Patio Installation
When planning your flagstone patio installation, understanding the costs involved is crucial. Hiring a professional can ensure a polished finish and minimize potential issues. Here’s what you need to know about labor and material costs.
Labor Costs
Hiring a professional to install your flagstone patio can be an investment, but it often ensures a more polished finish. On average, professional installation costs range from $3,000 to $5,400 for a standard 200 square foot patio. Labor costs make up a significant portion of this expense because professionals have the experience to quickly and efficiently level the area, cut stones, and ensure proper drainage.
Material Costs
Flagstone is a natural stone, and its beauty comes with a price. The cost of materials can vary based on the type of stone you choose. For example, bluestone and limestone might be more expensive than sandstone or slate. On average, expect to pay $1,400 to $1,500 for a pallet of flagstone, which covers about 120 square feet. This equates to roughly $10 to $12 per square foot.
Average Cost Per Square Foot
When all is said and done, the total cost per square foot for a flagstone patio can range from $15 to $27. This includes both materials and labor. This cost can fluctuate based on location, the complexity of the project, and the specific materials chosen.
Next, we’ll address some frequently asked questions about flagstone patio installation to help you make informed decisions.
Frequently Asked Questions about Flagstone Patio Installation
When considering flagstone patio installation, several common questions often arise. Here, we’ll provide expert insights to help you make informed decisions for your project.
What to Put Under a Flagstone Patio?
The foundation of your flagstone patio is crucial for its longevity and stability. A well-prepared base can prevent shifting and settling over time. Here’s what you should consider:
- Gravel: A compactible gravel base is essential. It provides a stable foundation and aids in drainage. Type 2 gravel, commonly used under roads, is a popular choice due to its durability.
- Crushed Limestone: This can be an alternative to gravel. It compacts well and provides a solid base, though it may be more expensive.
- Base Material: Always ensure the base material is compacted properly. This prevents the stones from moving and helps maintain a level surface.
Does Flagstone Need to Be Cemented?
Flagstone can be installed with or without cement, depending on the method you choose:
- Dry-Set Method: This involves setting the stones directly on a compacted base of gravel and sand. It’s a flexible option that allows for adjustments if needed.
- Mortar Method: This method involves setting the stones in a bed of mortar. While it provides a more permanent and stable surface, it requires a concrete foundation to prevent cracking. This method is more labor-intensive and is best suited for those seeking a more polished finish.
What is the Best Material to Put Between Flagstones?
The material you choose to fill the gaps between flagstones affects both the appearance and functionality of your patio:
- Sand: Builder’s sand is a common choice. It’s easy to apply and provides a clean look, but may need replenishing over time due to erosion.
- Polymer Sand: This is a more advanced option. When activated with water, it hardens like mortar, securing the stones in place. It also discourages weed growth.
- Gravel: For a more natural look, small gravel can be used. It allows for drainage but may shift over time.
Choosing the right materials and methods for your flagstone patio is essential for ensuring its durability and aesthetic appeal. In the next section, we’ll wrap up with a summary of the benefits of flagstone patios and how Steve’s Services Landscape Company can help bring your vision to life.
