About Floating Stairs
Custom Floating Stairs in Renton, WA
A floating staircase is one of the few changes that transforms how an entire floor of a house feels. Removing the risers and the closed framing opens up a room in a way that new flooring or paint simply cannot.
We design and fabricate custom floating stairs across Renton in mono stringer, double stringer, and cantilever configurations, with matching railings included. Our Kent shop is minutes away, so measuring, delivery, and any adjustment stay straightforward.
Our Renton floating stairs are built in collaboration with Floating Stairs Seattle, our sister company, combining their staircase experience with the railings we fabricate just up the road in Kent.
Floating Stairs Types
Explore Our Floating Stairs Types
Three structural approaches at three different levels of complexity, and we will tell you straight which one your opening actually suits.
Mono Stringer Stairs
Treads are supported by one central steel stringer.
- Clean and modern profile
- Open feel with less steel
- Strong support for daily use
The most economical route to a genuine floating stair, and the one that suits the majority of Renton openings.
Double Stringer Stairs
Treads are supported by two steel stringers.
- Very strong support system
- Great for wider stair runs
- Stable feel underfoot daily
Costs more in steel but earns it on a wider run or a busy family staircase where a solid feel underfoot matters.
Cantilever Stairs
Treads are anchored into a structural wall support.
- True floating stair effect
- Minimal visible structure
- Most open appearance
The most demanding and most expensive option, entirely dependent on the supporting wall. We assess honestly whether it is viable.
Interior Floating Stairs
Interior Floating Stairs in Renton Homes
Interior floating stairs open up the ground floor of a house by removing the visual wall a conventional staircase creates. In the newer Renton homes with open upper floors, that change is immediately obvious from the entry.
We design the system around your layout, ceiling height, and finishes, matching tread thickness and profile to your flooring and trim. Being close by, we measure the actual opening rather than working from assumptions, which matters on a retrofit.
Exterior Floating Stairs
Exterior Floating Stairs in Renton
Exterior floating stairs link decks and garden levels without the bulk of conventional framing, which is useful on the hillside lots around Talbot Hill and the Highlands where a heavy stair structure dominates a small yard.
Outdoor systems use durable steel stringers, non slip treads, and finishes specified for the Renton wet so the assembly holds up without constant attention. Matching glass, cable, or metal railings complete it.

Stairs and Railings Together
Floating Stairs and Railings From One Local Source
Sourcing a staircase and a balustrade separately is where mismatched finishes and awkward junctions come from, and it also means two suppliers pointing at each other when something does not line up. We handle both.
Floating Stairs Seattle brings dedicated staircase experience to the structure while our Kent shop fabricates the railings, and being close to Renton keeps the whole project easy to coordinate.

See What Our Customers Are Saying
Posted on Google Kristina G.Trustindex verifies that the original source of the review is Google. We're so thrilled with our new stair railings! Custom Railings WA and Mike's team did a high quality job from start to finish. We got the black powder coat finish with hemlock handrail in natural stain, which looks so elegant (see attached photos). The powder coat finish is really attractive, and we like that it's durable and not easily scratched. We were a little nervous that the wood color/characteristics on the top rail might turn out to be inconsistent across such a long run of railing, but the hand rails on all of the railings match beautifully. Thank you, Mike and team for taking such great care of us! Our new stairs are the perfect touch for our new farmhouse.Posted on Google Adele FesanTrustindex verifies that the original source of the review is Google. We used this company for the second time, and this was our first time ordering railing for an outdoor deck. The service was absolutely outstanding from start to finish. Communication was excellent, the team was easy to work with, and everything was completed exactly on schedule. The installation crew was highly professional, respectful, and left the area clean after completing the job. It was truly a pleasure working with a company that operates with such care and professionalism. The quality of the railing is top-notch — a very high-end product that exceeded our expectations. We would highly recommend this company and will definitely use them again in the future.Posted on Google Leyla HasanovaTrustindex verifies that the original source of the review is Google. We ordered glass railings for our parents’ home in Seattle. We were choosing between two options, glass or modern metal railings, and in the end we decided to go with glass. We’re extremely happy with that choice. The team helped us understand the differences, guided us through the design, and completed the installation on time. The railings look amazing. Great experience overall!Posted on Google Zamina BabayevaTrustindex verifies that the original source of the review is Google. From the first day, they were professional and easy to work with. Mike always replied quickly, and the team made sure every detail was just how I wanted. In the end, we got beautiful glass railings that fit perfectly with our modern home in Bellevue. Thank you, Custom Railings WA, for making the whole process smooth and enjoyable!Posted on Google J BTrustindex verifies that the original source of the review is Google. I had such a good experience getting outdoor railings for my front concrete steps and for my stone steps in the back garden. I had put off doing this for so long and thought that railings might detract from the aesthetic look of my yard, but I was so wrong. I absolutely love my new railings, and loved working with all the guys who came out - to measure, to bend the metal and dig post holes, and finally to install the finished railings. Thank you!Posted on Google Jill SprattTrustindex verifies that the original source of the review is Google. We had a wonderful experience with Mike and his crew at Custom Railings WA. From design planning to installation they were knowledgeable, patient, helpful and professional.Posted on Google K CarrollTrustindex verifies that the original source of the review is Google. Fantastic experience. Could not be more thrilled with the work Custom Railings did. Start to finish top notch work, excellent communication, very professional crew, wish all companies operated with such integrity, truly a pleasure to work with!Posted on Google Hanaa Abou OufTrustindex verifies that the original source of the review is Google. We have beautiful new railings thanks to Custom Railings. Good communication, beautiful product, and they made sure everything was clean before they left. I will definitely use them again in the future!Posted on Google Cathy MooreTrustindex verifies that the original source of the review is Google. We had a great experience with Custom Railings WA. They replaced our outdated railing with a new custom designed railing that fit our dreams and our budget. Communication was always clear and timely. They even worked around the chaotic schedule of other contractors working on our bigger remodeling project that impacted when the railing could be installed. Very Happy with our railing.

Frequently Asked Questions
Do the railings come with the stair?
CustomRailingsWA2026-09-08T11:06:07-07:00Yes, and that is deliberate. We fabricate the railings ourselves, so the balustrade is designed alongside the staircase and finished to match rather than being sourced separately and fitted afterward. Glass, cable, and metal are all options.
Does being close to Renton help?
CustomRailingsWA2026-09-08T11:05:33-07:00It does. Our Kent shop is minutes away, so measuring, delivering, and returning for adjustments is quicker than for a fabricator crossing the region, and there is no travel charge on a Renton job. On a stair fitted to an existing opening, being able to come back easily is worth a lot.
Can a floating stair replace our existing staircase?
CustomRailingsWA2026-09-08T11:04:53-07:00Often yes, though it depends on the opening, the surrounding structure, and the clearances available. A retrofit is a bigger job than a new build installation because the existing framing has to come out and the new structure has to be supported properly. We measure the actual opening before quoting so the number reflects your house.
Which floating stair type is most cost effective?
CustomRailingsWA2026-09-08T11:04:26-07:00A mono stringer, generally. One central steel spine uses less material than a double stringer and needs far less structural provision than a cantilever, while still giving a genuine floating look with open risers. For most Renton openings it is the sensible starting point, and we will say so rather than pushing the more expensive option.
