Cost to build deck stairs from scratch
The cost to build deck stairs from scratch depends on whether you're adding them to an existing deck or including them in a new deck project.
Adding stairs to an existing deck costs $1,400 to $2,600 for a standard installation. This includes the materials, labor, and any necessary structural modifications to attach the stairs securely to your existing deck frame. The higher cost reflects the need for custom fitting and potential reinforcement work.
Including stairs in a new deck project adds about $200 to $600 to your total deck construction cost. This covers average stairs made from standard materials. The cost is lower than adding stairs to an existing deck as contractors can integrate the stair construction with the overall deck build, sharing equipment setup and labor efficiency.
Cost to replace deck stairs
The cost to replace deck stairs ranges from $500 to $1,500 for most projects, depending on materials and design complexity. This price includes removal of old stairs and installation of new ones.
Replacement projects are often cheaper than building from scratch because the deck structure already exists. However, costs can increase significantly if structural repairs are needed or if you're upgrading to premium materials. Simple pressure-treated wood replacements fall on the lower end, while composite or exotic wood upgrades push costs higher.
Deck stairs cost calculator
Multiple factors affect the final cost to build a staircase for a deck:
Location: Installations in urban locations often cost more than in rural areas due to higher contractor rates and material delivery charges. Projects also tend to cost more in areas with strict building codes or challenging weather conditions.
Climate: In cold regions, the frost line depth affects foundation requirements; deeper footings for stair support increase excavation and concrete costs.
Time of year: Seasonal demand affects contractor pricing, with professionals in most regions charging premium rates for deck stair installations in the spring and summer months.
Size & height requirements
The stair dimensions directly affect material requirements and labor hours. The height from the deck to the ground determines the stringer length and the number of steps required. Each additional step increases costs for treads, risers, and support materials. Wider stairs also require additional stringers for proper support.
Design complexity & features
Simple, straight deck stairs cost less to build than curved or angled designs. Multi-directional stairs with landings require additional framing and materials. Built-in features like storage compartments, lighting, or decorative elements add to both material and labor costs.
Railing requirements also impact the total project cost. Some regions require railings for a staircase with more than three steps. Basic wood deck railings cost $20 to $50 per linear foot installed, while premium materials like composite or metal can cost up to $250 per linear foot.

Stair components
Deck stairs consist of several components, all essential for structural integrity and building code compliance. Stair tread prices vary widely based on your material choice; basic pressure-treated treads start around $15 each, while premium wood or high-end composite can reach over $250 each.
The table below shows the various deck stair components and their average costs.
| Component | Average price* | Description |
|---|---|---|
| Treads | $15 – $250 each | Horizontal walking surface; varies by material quality |
| Stringers | $115 – $200+ each | Structural support frames; minimum three required |
| Risers | $10 – $50 each | Vertical face boards placed between the steps |
| Joist hangers | $5 – $15 each | Metal brackets connecting stringers to deck frame |
| Fasteners and screws | $20 – $50 per set | Galvanized hardware for entire stair assembly |
| Concrete footings | $300 – $500 total | Landing pad foundation at the bottom of stairs |

Site preparation
Beyond basic stair construction, several additional expenses may apply to your project to ensure a safe installation:
Level surface: Proper stair installation requires level, stable ground at the bottom landing. Land leveling costs $500 to $1,000 for a small yard or patio area. Some sites may require additional grading or drainage work to ensure proper water runoff.
Solid landing: A concrete pad for deck stairs costs $300 to $500 on average. Alternative options include gravel bases or paver systems, which cost less but may not meet all building code requirements.
Landscape removal: If needed, removing existing landscaping can add $200 to $500+ to the project cost.
Material choice
Material selection dramatically impacts your final project cost. Each option offers different benefits in terms of appearance, durability, and maintenance requirements. Pressure-treated lumber is the most budget-friendly option. Higher wood grades, composite materials, and metal options cost more initially but reduce your long-term maintenance and replacement needs.
The table below shows the average cost per step for various deck stair materials.
| Material type | Average cost per step* | Lifespan (years) | Details |
|---|---|---|---|
| Pressure-treated deck stairs cost | $30 – $60+ | 10 – 25 | Budget-friendly; requires regular maintenance |
| Cedar and redwood | $50 – $75+ | 15 – 20 | Resists insects and decay naturally; attractive appearance |
| Composite deck stairs cost | $50 – $100+ | 25 – 50 | Low maintenance; fade resistant |
| Ipe and exotic hardwood stairs cost | $100 – $250+ | 40 – 70 | Premium durability; low maintenance |
| Metal and aluminum | $75 – $200+ | 30+ | Maximum durability; modern aesthetics |
*Including materials and installation labor
Consider composite materials for high-traffic stairs. The reduced maintenance and longer lifespan often justify the premium pricing. Use pressure-treated lumber for hidden structural elements to reduce the overall project cost. Avoid the cheapest wood grades that warp and split quickly.
Labor & installation
Professional installation accounts for 40% to 60% of the total project cost. Labor rates vary by region, contractor experience, and project complexity. Simple installations require less time to complete, while complex designs requiring custom work often take longer and cost more.
Standard carpenter rates range from $30 to $100 per hour on average. A skilled master carpenter may charge $100 to $200+ per hour but may be worth the extra cost for a complex or custom deck stair installation.
Permit fees range from $50 to $300+ depending on local requirements and the project scope. Most contractors include permit and inspection fees in their estimate.
Bundling projects
Combining your deck stair installation with other work may offer potential discounts. Contractors often reduce rates for larger projects that justify equipment setup and travel costs.
Professional deck painting costs $2 to $5 per square foot on average.
The cost to stain a deck ranges from $1.50 to $4.00 per square foot for the materials and labor.
Refinishing a deck costs $3.00 to $6.50 per square foot to strip the existing stain and apply a new stain and sealer.
Deck repairs cost anywhere from $100 to $2,500+, depending on the material, damage, and the extent of the repair work.

Maintenance and longevity
Long-term costs vary dramatically by material choice. Most pressure-treated wood needs annual cleaning and minor repairs to maintain appearance and structural integrity, as well as sealing every 2 to 3 years to keep it protected from moisture and UV ray protection. Composite and metal stairs cost more up front but need minimal maintenance beyond occasional cleaning.
Deck stairs FAQs
How wide should deck stairs be?
Deck stairs should be at least 36 inches wide for safe passage. Many homeowners choose 48-inch widths for more comfortable use and better aesthetics. Wider stairs cost more due to the extra materials required, but they can better accommodate moving furniture and feel more spacious overall.
Commercial applications may require wider stairs. Always check local building codes for specific width requirements in your area.
Do deck stairs need footings?
Yes, most deck stair installations require concrete footings for stability and code compliance. Footings must extend to frost depth, with a minimum of 42 inches in many regions. Proper footings prevent settling and ensure long-term structural integrity.
Can deck stairs land on grass?
Deck stairs should land on a stable, well-drained surface rather than directly on grass. Most building codes require a concrete pad or gravel base at the bottom of stairs for safety and durability. A proper landing pad prevents erosion and provides stable footing in all weather conditions.
Can you buy premade deck stairs?
Yes, premade stair systems are available for standard deck heights and widths. Prefabricated stairs work well for straightforward installations but may not fit unique deck configurations. Although custom-built stairs cost more, they offer perfect fit and more design flexibility.
