Factors Influencing the Cost of Exterior Stairs
Material Costs
The choice of materials significantly impacts the overall cost of building exterior stairs. Common materials include wood, composite, concrete, and metal, each with its price range and durability.
Wood: $1,400 - $4,200
Wood is a popular choice for exterior stairs due to its natural look and versatility. The cost of wood stairs depends on the type of wood used, such as pressure-treated lumber, cedar, or redwood. Pressure-treated lumber is the most affordable, while cedar and redwood are more expensive but offer better resistance to weather and insects. Regular maintenance, such as staining and sealing, is necessary to prolong the lifespan of wood stairs. Additionally, wood stairs can be customized to match the style of your home, offering both aesthetic and functional benefits.
Example: Building a set of wood stairs with pressure-treated lumber for a deck entryway. The cost includes the materials, construction, and finishing to ensure durability and a polished appearance. Wood stairs offer a classic look and can be customized to fit any design aesthetic. Regular maintenance ensures longevity, making wood a cost-effective choice in the long run.
2. Composite: $2,800 - $7,000
Composite materials are made from a blend of wood fibers and plastic, offering durability and low maintenance. Composite stairs are resistant to rot, insects, and weather damage, making them a long-lasting option. The initial cost is higher than wood, but the reduced maintenance expenses over time can make them a cost-effective choice in the long run. Composite materials also come in various colors and finishes, allowing homeowners to achieve a desired look without the upkeep required for natural wood.
Example: Installing composite stairs for a backyard deck. The cost includes the composite boards, railings, and installation labor. Composite materials come in various colors and finishes, allowing for customization to match your home’s exterior. The durability and low maintenance of composite materials make them an excellent investment, providing a beautiful and resilient addition to your outdoor space.
3. Concrete: $2,100 - $6,300
Concrete stairs are durable and require minimal maintenance. They are ideal for high-traffic areas and can be customized with various finishes, such as stamping or staining, to enhance their appearance. The cost of concrete stairs depends on the size, design complexity, and any additional features like railings or decorative elements. Concrete’s durability makes it a practical choice for exterior stairs, capable of withstanding heavy use and harsh weather conditions.

Example: Constructing concrete stairs for a front entryway. The cost includes materials, labor, and finishing techniques to achieve the desired look. Concrete stairs provide a sturdy and long-lasting solution, suitable for both modern and traditional home styles. Custom finishes and decorative elements can be added to enhance the aesthetic appeal, making concrete a versatile choice for exterior stairs.
4. Metal: $4,200 - $11,200+
Metal stairs, typically made from steel or aluminum, offer a sleek and modern look. They are highly durable and resistant to weather damage, making them suitable for various climates. The cost of metal stairs depends on the type of metal used, design complexity, and any additional treatments like powder coating for added durability. Metal stairs can be designed with intricate patterns and finishes, adding a unique touch to your property’s exterior.
Example: Installing steel stairs for a side entrance. The cost includes materials, fabrication, and installation. Metal stairs can be designed with intricate patterns and finishes, adding a unique touch to your property’s exterior. The durability and modern aesthetic of metal stairs make them a popular choice for contemporary home designs, providing both functionality and style.
Design and Size
The design and size of the stairs also affect the overall cost. Simple, straight stairs are more affordable than curved or multi-level designs. The number of steps, the inclusion of landings, and the need for railings or handrails also contribute to the cost.
