Installing a Floating Staircase: What Contractors and Homeowners Need to Know
A custom floating staircase may be fabricated hundreds of miles from the home where it will eventually be installed. So how does installation actually work, and who installs it?
At Iron Timbers, our floating staircase systems are fabricated in our Indiana shop and shipped to projects throughout the continental United States. That makes coordination between our team and the people working onsite an important part of every project.
From field measurements and shop drawing verification to delivery, stringer placement, tread installation, and railing, here's what contractors and homeowners should know about installing a custom floating staircase.
Who Installs an Iron Timbers Floating Staircase?
The first question many homeowners ask is:
“Who is going to install my floating staircase?”
For most projects, the answer is the builder, general contractor, or carpenter already working on the home.
On a new construction project, there is typically already a contractor involved who understands the construction schedule and the conditions surrounding the staircase opening. Iron Timbers works directly with that contractor throughout the process to make sure the staircase is fabricated correctly and ready for installation when it arrives onsite.
For remodel projects, the process can require more planning. Replacing an existing staircase with a floating staircase may involve changes to surrounding finishes, flooring, blocking, trim work, drywall, or other existing conditions.
Because of that, homeowners considering a staircase replacement should involve a qualified contractor early in the process.

Contractor Coordination Starts Before Fabrication
Installing a floating staircase is not something that begins when the truck arrives.
The process starts much earlier.
The contractor is often the person providing Iron Timbers with the field measurements needed to create the staircase. In some cases, the homeowner may provide those measurements, but experienced builders typically prefer to be involved because they will ultimately be responsible for installing the system.
After measurements are received, Iron Timbers creates detailed CAD shop drawings showing the proposed staircase system.
Those drawings are then sent back to the contractor for verification against the actual field conditions.
Once the contractor confirms that the drawings match the project dimensions, fabrication can begin.
This process creates a direct connection between the jobsite, the drawings, and the staircase being built in our shop.
What Comes With an Iron Timbers Staircase System?
When a customer purchases a complete IRON Floating Staircase System, the goal is to provide a coordinated package rather than separate pieces from multiple suppliers.
Depending on the project, the system can include:
Steel mono-stringer or stringer sections
Riser and tread plate assemblies
Finished hardwood treads
Custom steel railing
Required hardware and fasteners
Installation documentation
Because the staircase is designed around the specific project conditions, Iron Timbers knows how the system is intended to mount and supplies the appropriate components for those connections.
The only exceptions are project-specific items outside our standard scope, such as a homeowner choosing a separate railing system like glass or cable.
See how the steel stringer, tread supports, hardwood treads, railing, and other components are produced in How Are Floating Staircases Fabricated? From Steel and Hardwood to a Finished Stair System.
What Happens When the Staircase Arrives?
A common misconception is that the staircase arrives and is immediately installed.
That is not always the case.
Because custom staircases are often fabricated before a project reaches the installation stage, shipments may arrive onsite before the contractor is ready to install them.
The staircase components can be safely stored until the space is prepared.
Installation typically occurs once the surrounding construction is complete enough to accept the system, including finished wall conditions and flooring finishes.
This allows the contractor to install the staircase at the correct point in the construction schedule rather than rushing the process.
The First Step: Installing the Steel Stringer
The most important part of the installation process is positioning the steel stringer.
Depending on the staircase design, this may involve one or multiple stringer sections.
The stringer establishes the foundation for the rest of the staircase. Once it is installed correctly and secured in position, the remaining components are designed to locate from that structure.
If the stringer is installed incorrectly, it can affect the alignment of the rest of the system.
This is why careful layout, leveling, and verification during this first stage are so important.

Installing the Remaining Stair Components
After the stringer is installed, the remaining components are installed in sequence.
The typical installation order is:
Stringer(s) → Riser/tread plate assemblies → Hardwood treads → Railing
The riser/tread plate assemblies attach to the stringer and create the support structure beneath each tread.
The hardwood treads are then installed onto those assemblies, followed by the railing system.
Throughout installation, contractors should continue checking that components remain level and square as the system comes together.
The majority of the layout is established during stringer installation. From there, the process becomes assembling the coordinated components and verifying alignment throughout.
What Tools Are Needed to Install a Floating Staircase?
Most IRON Floating Staircase installations can be completed using common construction tools rather than specialized staircase-specific equipment.
Most of the assembly uses common construction tools, including:
Wrenches
Impact drivers
Tape measures
Squares
Levels
The one area that may require additional planning is moving and positioning the steel components.
Depending on the staircase size, layout, and site conditions, contractors may need lifting equipment such as:
Electric hoists
Chain hoists
Straps
Proper rigging equipment
Individual stringer sections can weigh several hundred pounds, so the contractor should consider the safest method for moving and positioning the components before installation begins.
Installation Support From Iron Timbers
Building a staircase system that ships nationwide requires more than just sending components in a crate.
Iron Timbers provides installation guides specific to the type of staircase being installed, including:
Straight-run systems
Switchback systems
Winder systems
These guides help contractors understand the assembly process and reference the proper installation sequence.
If questions come up during installation, our team remains available to provide direct support over the phone.
Every project has unique conditions, and having access to the team that designed and fabricated the system can help contractors work through those questions.
Can a Homeowner Install a Floating Staircase?
The answer depends on the homeowner's experience.
A homeowner with a strong construction background may have the ability to install an IRON Floating Staircase System.
However, the staircase itself is only one part of a larger remodel project.
Replacing an existing staircase can involve additional work such as:
Removing the existing staircase
Adjusting flooring transitions
Modifying blocking
Completing drywall and trim work
Addressing existing structural conditions
For homeowners without construction experience, working with a qualified contractor is typically the best way to ensure the entire project, not just the staircase, is completed properly.
Why a Complete Staircase System Makes Installation Easier
One of the biggest advantages of working with Iron Timbers is that the contractor is not trying to coordinate multiple specialty suppliers.
A floating staircase can involve:
Steel fabrication
Hardwood treads
Railing fabrication
Finishing
Lighting
Hardware
When those pieces come from different sources, the contractor or homeowner becomes responsible for making sure everything works together.
Iron Timbers handles those details as one coordinated system.
The result is a staircase package that arrives ready for the contractor to install rather than a collection of unrelated components that have to be figured out onsite.
A Nationwide Staircase With Local Installation Support
One of the advantages of a custom floating staircase system is that it does not require the manufacturer to be physically located near every project.
Iron Timbers works with builders and contractors throughout the country by combining:
Custom fabrication
Detailed shop drawings
Complete component packages
Installation documentation
Direct contractor support
The contractor brings the local knowledge of the project, while Iron Timbers provides the custom staircase expertise.
Together, that allows a staircase fabricated in Indiana to become the centerpiece of a home anywhere in the country.
Planning a Custom Floating Staircase?
Whether you are a homeowner, builder, or contractor, the best time to start the conversation is before the project reaches installation.
