At Reliable Design-Build-Remodel, we take pride in being one of Birmingham, Alabama’s most trusted deck and stair builders. Whether you’re adding a deck to your backyard oasis or constructing a new staircase to improve home access and safety, understanding the costs, materials, and building codes involved is essential. In this post, we’re answering the most common questions homeowners have when planning for stair construction, especially in the context of decks.
How much does it cost to build stairs?
The cost to build stairs varies significantly depending on materials, design complexity, and location. For a simple wooden exterior deck staircase, you can expect to pay anywhere from $15 to $35 per step, which includes both labor and materials. Interior stairs, which may involve more custom design and finishing work, tend to be more expensive, averaging between $1,000 to $5,000 for a standard straight flight. Curved, spiral, or open-riser staircases can quickly exceed those figures due to their intricacy and required structural planning. At Reliable Design-Build-Remodel, we assess each project individually and provide clear, honest quotes so you can plan confidently.
How much does construction of a staircase cost?
When considering the construction of an entire staircase—especially indoors—you should prepare for a wider range of costs. Factors like whether it’s a new build or retrofit, the materials used (hardwood, steel, glass, or composite), and the number of flights all contribute to the final price. On average, homeowners spend between $2,000 and $10,000 for full staircase construction. For exterior deck stairs, the overall price can be much lower, especially when using pressure-treated lumber and standard railings. We always recommend scheduling a site visit with a contractor like us to assess your space and needs before making any budget decisions.
How expensive is a new staircase?
A new staircase can be a substantial investment depending on the scope of the project. For interior staircases in multi-level homes, expect to pay more due to additional framing, finish work, and compliance with building codes. Premium materials like oak, wrought iron, or glass can increase costs, as can design elements like landings or double-backs. Exterior deck staircases, on the other hand, tend to be less expensive—especially if you’re using economical wood options. Our team at Reliable Design-Build-Remodel can work with a range of budgets to deliver safe, code-compliant, and attractive staircases for your home.
Which is cheaper: concrete or steel stairs?
When comparing concrete and steel stairs, concrete is generally the more affordable option, especially for exterior use. Concrete stairs are durable and relatively low-maintenance, making them popular for porches and back entrances. However, installation requires formwork, curing time, and often a more extensive foundation. Steel stairs offer a sleek, modern look and can be prefabricated offsite, which sometimes helps reduce labor costs. However, steel is typically more expensive upfront. For decks, most homeowners in Birmingham opt for pressure-treated wood due to its affordability, but we’re happy to explore concrete or steel options for your project if that’s your preference.
Why are deck stairs so expensive?
Many homeowners are surprised by how much deck stairs cost, especially when compared to interior steps. Several factors contribute to this. First, deck stairs require weather-resistant materials, which can be more expensive than standard indoor finishes. Second, exterior stairs often need deeper footings or concrete piers to meet code requirements and withstand shifting soil. Third, the cost of railings, balusters, and safety features must be factored in. Additionally, labor costs can increase due to the extra time required to dig, level, and build in outdoor environments. At Reliable Design-Build-Remodel, we provide detailed breakdowns to help you understand where your money is going and how to make the most of your investment.
What is the 27 rule for deck stairs?
The “27 rule” is a helpful guideline used by deck and stair builders to ensure that stairs are both safe and comfortable to use. The rule suggests that the sum of one stair tread (the horizontal part you step on) and two risers (the vertical parts between each tread) should equal approximately 27 inches. For example, if each riser is 7 inches, then the tread should be around 13 inches to keep the steps ergonomic. While it’s not a formal code, this rule provides a useful reference point when designing stairs to avoid awkward or unsafe steps. At Reliable Design-Build-Remodel, we blend builder intuition with code compliance to create stairs that feel just right.
What is the 7-11 rule for stairs?
The 7-11 rule is another common rule of thumb in staircase design. It refers to a riser height of 7 inches and a tread depth of 11 inches—measurements that are widely considered ideal for both safety and comfort. This ratio strikes a balance between steepness and usability, making it easier for people of all ages to ascend or descend stairs. Most residential building codes in Alabama align closely with these dimensions. As experienced deck and stair builders, we ensure every staircase we construct not only meets code but also feels natural and secure for everyday use.
