Where Floating Stairs Shine in Renton
Start with Kennydale. The hillside above Lake Washington holds some of the best view homes in south King County, and in those houses the staircase often sits directly between the living space and the water. A solid staircase there is a wall in front of your best feature. A floating one lets the lake stay visible through the open risers, which is why Kennydale produces more of our Renton calls than any other neighborhood.
Then there’s the rest of the city, which is remodeling fast. The Highlands, Benson Hill, and Fairwood are full of homes from the 60s through the 90s getting opened up, and newer construction keeps filling in around The Landing and the downtown core. In both cases the pattern is the same: once the floor plan opens up, the old enclosed staircase is the last dark thing in the house, and swapping it for a floating system finishes the job.
Renton Neighborhoods We Serve
We build across the whole city: Kennydale, the Renton Highlands, Fairwood, Benson Hill, Talbot Hill, Maplewood, the Cascade and Petrovitsky corridors, President Park, Liberty Ridge, and the newer communities off Duvall Avenue. Downtown Renton and The Landing area are in the loop too, along with the May Valley edges heading toward Newcastle.
Because the shop is so close, no Renton address is inconvenient for us. That kind of responsiveness is hard to offer when a contractor is coming from across the bridges, and it’s our home-field advantage here.

Stairs & Railings
Pair with Railings
by Custom Railings WA
Every staircase we build in Renton can come with its railing system from the same shop, through our sister company CCustom Railings WA. That’s cable railings, steel rail systems, and frameless glass guardrails, designed alongside the staircase so the connection points, finishes, and sight lines are resolved before fabrication starts.
In Kennydale view homes, frameless glass earns its cost by keeping the lake visible from the stair itself. In family homes across the Highlands and Fairwood, cable rails and horizontal steel bars deliver the modern look with more durability against kids, dogs, and daily life. One consultation covers both the stairs and the railing, with samples you can hold.
Mono Stringer
Mono Stringer Stairs in Renton
The mono stringer suspends the whole staircase from a single steel beam running up the center, treads mounted to both sides. It’s our most installed system in Renton, partly because it delivers the complete floating look at the friendliest price of the three, and partly because it fits nearly every layout the city throws at it.
Each beam is built for your exact rise and run, fabricated nearby in Kent, and powder coated in the finish you choose. White oak treads over matte black steel is the combination most Renton clients land on.
Double Stringer
Double Stringer Stairs in Renton
Double stringer staircases carry their treads between two steel beams, one on each side. The extra structure means wider treads, longer runs, and a dead-solid feel underfoot, with none of the flex you can get from lighter systems. For the multi-level homes stepping down Renton’s hillsides, especially in Kennydale and Talbot Hill, this is usually the right call.
The two-beam format is also the flexible one for design. Switchback layouts, thick slab treads, integrated under-tread lighting, and mixed materials all work cleanly. Each staircase is built to the precise dimensions of your run, so it feels solid underfoot and fits the opening exactly.
Cantilever
Cantilever Stairs in Renton
Cantilever staircases hide the entire structure inside the wall. Concealed steel brackets carry each tread individually, so the finished stairs read as pure floating planes with nothing beneath them. When Renton homeowners bring us a photo and say they want that, it’s almost always a cantilever in the photo.
We coordinate closely with your builder so the staircase integrates cleanly with the rest of the project. During the free consultation we’ll tell you honestly whether a cantilever is the right fit for your space, or design you a mono stringer that gets most of the same effect.

Our Process
How We Build Your Renton Staircase
A Renton project starts with a free consultation at your home, easy to schedule since the shop is so close. We measure, evaluate the structure, and talk through what you want. Then you get detailed drawings and one firm price, and nothing proceeds without your approval on both.
After that it’s fabrication in Kent, finishing, and installation with our own crew. It depends on the project. Timelines vary with the stair system, materials, and your home, and you hear from us at every milestone along the way.
Consultation
We learn your space, goals, style, budget, and timeline for the project.
Design
We create a custom stair concept shaped to your layout and architecture.
Fabrication
We build each stair component with precision, strength, and clean detail.
Installation
We install the staircase carefully for a seamless fit and finished look.
