The Elegance of Floating Staircases

A floating staircase creates a dramatic visual effect, making a space feel larger, more open, and undeniably modern. Each tread appears to float, supported by a hidden structural beam. We are experts in fabricating these intricate structures to meet and exceed all Maine building codes. Our team ensures that while the design is light and airy, the craftsmanship is robust and secure, providing a safe and spectacular feature for your home or business.


Mono Stringer vs. Double Stringer Stairs

Understanding the structural differences is key to choosing the right staircase for your space.


  • Mono Stringer Staircases: This design features a single, central steel beam running beneath the treads. It offers a clean, minimalist look that is both strong and visually appealing. We often recommend this style for modern or industrial-themed interiors.
  • Double Stringer Staircases: This is a more traditional design with two parallel steel beams on either side of the treads. It provides a classic, robust look and is often used in larger or more traditional settings.


Both options offer incredible strength and are fully customizable in terms of materials, finishes, and handrail designs.

Frequently Asked Questions about Custom Staircases

  • What is a "floating staircase" and is it safe?

    A floating staircase is a modern design where the treads are cantilevered from a single stringer or hidden structural support, giving the illusion of floating. They are completely safe and are engineered to be structurally sound and fully compliant with all Maine building codes.

  • What is the typical cost for a custom steel staircase?

    The cost of a custom staircase varies widely depending on the design complexity, materials (e.g., steel, wood, glass), and the type of finish. We provide a detailed, transparent quote after an initial design consultation to ensure there are no surprises.

  • How long does the fabrication and installation process take?

    The timeline for a custom staircase project depends on its complexity. We work closely with you to set a clear timeline from design approval to final installation. Our goal is always to complete your project efficiently without compromising quality.
