Custom Floating Staircase Installation Across Washington, DC
Some staircases fill a space. Others define it. At Floating Stairs DC, we design and install floating staircases that become the architectural centerpiece of Washington, DC homes, engineered from the ground up for the specific demands of this city and the people who live in it.
Backed by Capitol Iron Works
Floating Stairs DC is the dedicated Washington, DC division of Capitol Iron Works, a structural fabrication operation with decades of metalwork and architectural steel history across the DMV region.
Capitol Iron Works did not begin in the residential staircase market. Its roots are in structural ironwork, the kind of precision fabrication that serves commercial buildings, federal interiors, and institutional projects where engineering tolerance is non-negotiable and finish quality is permanently on display. That fabrication heritage is what separates us from every other staircase company operating in the DC market today.
When you commission a floating staircase through our DC division, the design flows directly to the Capitol Iron Works fabrication floor. There is no outsourced steel, no third-party manufacturer interpreting our specifications through their own production constraints, and no variation between what was designed and what arrives at your home. The same AISC-certified fabrication standards that Capitol Iron Works has applied to decades of structural metalwork across the DMV are applied to every residential staircase we build.
White-Glove Installation
Our white-glove installation service covers the full scope from initial structural survey through laser-aligned assembly to final compliance documentation and handover. We work cleanly inside occupied homes and leave every site in better condition than we found it.
Custom Staircase Design
Every home we design for receives a staircase concept built specifically around its architecture, not selected from a product range. We use 3D BIM modeling to place the design inside a digital replica of your actual home before a single component is fabricated.
Integrated LED Lighting
Stair lighting that is recessed into the staircase structure during fabrication produces a result that surface-mounted systems simply cannot achieve. We design integrated LED systems compatible with Lutron, Control4, and Savant home automation platforms.
Modern Railing Systems
We fabricate frameless glass panels, horizontal cable rail, and custom steel balustrade systems as structural components of the staircase itself, engineered alongside the stringer from the beginning of the design process.
Renovation and Retrofitting
We retrofit existing stair structures into open modern designs by working intelligently with what is already there, reinforcing or replacing only what the new design requires. A full structural rebuild is rarely the answer for a DC home with a traditional staircase.
Commercial and Custom Projects
Capitol Iron Works brings its full commercial fabrication capability to floating staircase projects in DC office environments, retail interiors, and mixed-use developments. AISC-certified structural steel and PE-reviewed engineering documentation throughout.
Why Our Engineering Is Different
Every staircase we produce is fabricated from A36 structural steel, the same material grade used in commercial construction across the country. Primary stringers are engineered to carry the full live and dead load of the tread span without deflection under normal residential use. Every installation is delivered IBC compliant, with full structural documentation provided at handover.
The reason our staircases do not bounce, flex, or transmit movement underfoot comes down to cantilevered physics applied correctly. A cantilevered tread derives its rigidity from the quality of its connection to the stringer and the stringer''''s connection to the building structure. When those connections are engineered to the right specification, torqued correctly, and aligned to a 0.5mm tolerance, the tread behaves as a fixed structural element rather than a lever. The floating effect is visual. The performance is concrete.
We model every staircase in full 3D BIM software before fabrication begins. This process calculates load distribution, confirms deflection limits at each individual tread point, and identifies any conflicts with the existing building structure before they become field problems. By the time our installation team arrives on site, the engineering has already been fully resolved.
Georgetown
Georgetown''''s historic residential streets demand a staircase designer who understands the architectural sensitivity of the neighborhood as well as the structural constraints of its building stock. We bring both to every Georgetown project.
Capitol Hill
Capitol Hill rowhouses present a vertical living challenge that rewards a staircase designed around maximizing perceived space rather than consuming it. We work across the Hill with compact, high-impact floating staircase systems.
Chevy Chase
Chevy Chase estate homes sit at the top end of our DC residential market in terms of scale and material ambition. We design grand cantilevered staircase systems for the large open-plan interiors of this neighborhood.
Northwest DC
Northwest DC encompasses one of the broadest ranges of residential architecture in the city, from compact urban townhomes to substantial detached properties with serious foyer volumes.
Southwest DC
Southwest DC''''s evolving residential landscape includes a growing number of contemporary new-build and renovation projects where floating staircase design is increasingly central to the interior concept.
American University Park
The residential streets of American University Park combine generous lot sizes with traditional home architecture that is increasingly being updated for contemporary living. We work with homeowners throughout this neighborhood on retrofit and new installation projects.
Frequently Asked Questions
What makes a floating staircase different from a traditional staircase?
A floating staircase uses a structural steel stringer system to cantilever each tread without visible support beneath it. A traditional staircase relies on closed risers and a bulky balustrade structure to carry the load and define the form. The floating design opens up the surrounding space visually, allows light to pass through the stair volume, and produces a significantly more contemporary architectural result.
Are floating staircases structurally safe for everyday residential use?
Yes. Every floating staircase we install is engineered to current International Building Code (IBC) residential safety standards and applicable local requirements and fabricated from A36 structural steel to AISC specifications. The cantilevered tread system, when engineered correctly, is as structurally sound as any traditional staircase and in many cases more precisely engineered than the standard residential product it replaces.
Can a floating staircase be installed in a historic DC home?
Yes, though it requires a design approach that accounts for the specific structural and regulatory constraints of historic properties. In Georgetown and Capitol Hill, this means designing around existing masonry walls, working within historic review guidelines where applicable, and specifying anchoring systems compatible with the host materials of the building. We have extensive experience navigating these conditions across DC''''s historic residential neighborhoods.
How long does a full floating staircase project take from consultation to completion?
Most residential projects move from initial consultation to completed installation in eight to twelve weeks. The design approval and fabrication phases account for the majority of that timeline. Installation itself typically takes two to five days depending on the complexity of the design and the railing system specified.
Do you work with architects and interior designers on DC projects?
Yes. A significant portion of our DC project work involves collaboration with architects and interior designers who are specifying a floating staircase as part of a broader residential or commercial design. We provide full structural engineering documentation, 3D BIM model outputs, and material specifications in formats compatible with standard architectural drawing packages.
