How Much Does It Cost to Build a Patio?
A professionally installed backyard patio typically costs about $8 to $40+ per square foot, depending primarily on the material, patio size, site conditions, and amount of preparation required.
Plain concrete is generally the most affordable option at approximately $8–$18 per square foot, while stamped concrete typically costs $12–$25 per square foot. Interlock patios generally range from $15–$35+ per square foot, while natural stone or flagstone patios can cost approximately $18–$40+ per square foot.
What Can Increase the Cost?
Excavation, base preparation, grading, drainage, difficult backyard access, steps, retaining walls, and complex designs can increase the total project cost.
There’s an old Roman idea that a good life needs a good foundation. The same is surprisingly true of a backyard patio.
A well-built patio can turn an unused part of your yard into a place for summer dinners, quiet mornings, and long evenings outside. But before choosing the stone, furniture, or fire pit, there’s a more practical question: how much does it cost to build a patio?
The answer depends on more than square footage. Material choice, site preparation, grading and drainage, and design complexity can all affect the final cost.
For homeowners exploring options for hardscaping in Ottawa, this guide breaks down 2026 backyard patio costs, including pricing by material and size, what affects installation costs, and what to consider when planning your project.
How Much Does It Cost to Build a Patio?
The following table provides an at-a-glance comparison of typical patio costs by material, including the estimated cost per square foot and what you might expect to pay for a 200-square-foot patio.
| Patio Material | Cost Per Sq. Ft. | 200 Sq. Ft. Patio | Cost Level |
|---|---|---|---|
| Plain Concrete | $8–$18 | $1,600–$3,600 | $ |

Patio Cost Per Square Foot
The cost to build a patio typically ranges from $8 to $40+ per square foot, but the price per square foot varies considerably by material.
At the lower end, a basic poured concrete patio may cost around $8–$18 per square foot.
Stamped concrete typically ranges from $12–$25 per square foot, while interlock or paver patios generally cost $15–$35+ per square foot.
Natural stone and flagstone are typically the most expensive, at approximately $18–$40+ per square foot.
The per-square-foot price isn’t just the cost of the surface material. A professional installation may also involve excavation, base preparation, grading, compaction, drainage work, and installation labour, depending on the site and patio design.
Patio Cost by Material
Patio Cost by Size
Patio size is another major factor in the overall project cost. More square footage means more material, site preparation, and installation work, so looking at common patio dimensions can help you establish a realistic starting budget.

What Is Included in Patio Installation Cost?
A professional patio installation involves more than laying concrete, pavers, or stone.
The quoted price may include several stages of work needed to create a stable, properly graded surface that can withstand regular use and changing weather conditions.
Typical Scope of Work
Removing soil, grass, existing hardscaping, or other material required to prepare the patio area.
Installing and compacting the appropriate granular base to create a stable foundation for the finished patio.
Establishing the appropriate slope so water drains away from the patio and nearby structures.
Pouring and finishing concrete or installing individual pavers, interlock, or natural stone.
Cutting and fitting materials around edges, curves, steps, borders, and other design features where required.
Securing pavers or stone and completing the finished surface according to the selected installation method.
Removing excess materials and construction debris once the installation work is complete.
The exact scope depends on the property, patio design, material, access, and site conditions. Confirm what is included in the final estimate before work begins.
What Factors Affect the Cost of Building a Patio?
Even patios of the same size can vary significantly in price. Site conditions, preparation requirements, access, drainage, and design choices all influence the final cost.
Patio Material
The material creates one of the largest differences in price. Plain concrete typically costs $8–$18 per square foot, stamped concrete $12–$25, interlock $15–$35+, and natural stone or flagstone $18–$40+.
Material choice can also affect installation time, labour, base requirements, and the amount of cutting or finishing required.
Site Preparation & Excavation
Before installation begins, grass, soil, existing concrete, old pavers, or other materials may need to be removed. A site requiring deeper excavation, demolition, or significant clearing will generally require more labour, equipment, and disposal than an open, ready-to-build area.
Base Preparation
A properly prepared base helps support the patio and reduce movement and settlement over time. The amount of granular material, excavation, compaction, and other preparation required will depend on the existing soil and the type of patio being installed.
Grading & Drainage
Patios need an appropriate slope to direct water away from the surface and nearby structures. Properties with drainage problems, significant elevation changes, or areas that collect water may require additional grading or drainage work before the patio can be installed.
Backyard Access
Access can have a significant impact on labour and equipment requirements. Narrow gates, fences, neighbouring structures, landscaping, or limited space may prevent larger machinery from reaching the backyard, requiring smaller equipment or more manual work.
Design Complexity
A straightforward rectangular patio is generally simpler to install than one with curves, multiple levels, intricate patterns, contrasting borders, steps, or integrated landscape features. More complex designs typically require additional materials, cutting, layout work, and installation time.
How to Get the Best Value From Your Patio Investment
Getting the best value from a patio doesn’t necessarily mean choosing the lowest-cost material or quote. The goal is to invest in the parts of the project that affect performance and longevity, while creating a space that fits your budget and how you plan to use it.
Working with an experienced paving and hardscaping company can also help you make the right decisions from the start—from choosing materials and planning the layout to addressing base preparation, grading, drainage, and other site-specific considerations.
Choose the Right Material for Your Needs
Consider more than the upfront price. Concrete offers a lower starting cost, while stamped concrete, interlock, and natural stone provide different levels of customization and appearance. Choose a material based on your budget, maintenance expectations, design preferences, and how the patio will be used.
Invest in Proper Base Preparation
The finished surface is only as reliable as the foundation beneath it. Proper excavation, base material, grading, and compaction can help reduce settlement, shifting, and premature deterioration over time.
Get the Drainage Right
Water should move away from the patio and nearby structures rather than collecting on or beneath the surface. Addressing grading and drainage during installation can help prevent problems that may be more difficult and expensive to correct later.
Keep the Design Purposeful
Curves, intricate patterns, multiple levels, borders, steps, and other custom features can increase labour and material costs. Focus your budget on features that will genuinely improve how you use and enjoy the space rather than adding complexity for its own sake.
Think Beyond the Initial Price
Consider the long-term requirements of each material, including maintenance, repairs, cleaning, sealing, and the ability to replace damaged sections. A higher upfront investment may make sense if it better matches your long-term priorities.
Work With an Experienced Hardscaping Contractor
An experienced paving and hardscaping contractor can assess the site, identify potential grading or drainage issues, and help you plan the layout, choose appropriate materials, and determine the right base preparation for your property. Good planning from the start can help avoid costly corrections and create a patio that works better for the way you want to use the space.
Get an Accurate Patio Estimate
A patio starts with an idea of how you want to use the space. Maybe it’s a dining area, a place around the fire, or simply somewhere better to spend a summer evening.
From there, a consultation can turn that idea into a practical plan—looking at the available space, materials, layout, site conditions, and budget.
