Customer Q&A
Do you offer stairs that meet building code?
Sara C.
Yes, we do! Our SMA Certified Stair Designers are experts in your local building codes. We build thousands of stairs to code every year and we can do that for your project if you desire. The need to meet building code is required in some situations and in other situations code compliance may not be necessary. Please reach out to us to discuss further.
Do you have stairs for outdoor use?
Courtney B.
We have exterior spiral stair options that will last a lifetime outdoors. We have galvanized steel, raw aluminum, and powder coated aluminum stair material options! All of our outdoor spiral stairs are backed by a lifetime warranty.
Where do you ship your stairs?
Chris M.
We ship our stairs directly to consumers all across North America from our facility in Collegeville, Pennsylvania. All of our stairs are custom built to your specs and then shipped down you broken down in kit form for easy step-by-step DIY installation.
How much floor space do your stairs take up?
Ethan G.
The floor space a stair takes up is determined by the stair’s diameter. The smallest size diameter we offer is 3 feet 6 inches (42″ X 42″ floor footprint). Our standard diameters increase in six inch increments, 42″ x 42″ to 48″ x 48″ to 54″ x 54″ and so forth. We recommend that you place painters tape on the ground in the above dimensions to determine how the stair will look in your space.

The process with Paragon was so easy and straight forward. It fit perfectly into our Airbnb and opened up the loft bedroom. We feel great knowing our guests have a safe way to make it to the loft and they love the look! Installation was easy and took about 2 hours. This was the perfect affordable staircase that didn’t sacrifice design or sturdiness.

It was a great experience having Scott at Paragon help me with my spiral stairs. He was so helpful from start to finish. Great response time and follow up. I sent the measurements & pictures and he got right back with a drawing of my staircase.
My husband & a friend installed them and they are perfect.
Thank you Paragon & Scott

We wanted a way to reach the loft of our cabin rental without taking up too much space. The cabin is already on the smaller side and a traditional staircase would’ve been way too big. Paragon’s price point and aesthetic were exactly what we were looking for.

I had an overall excellent experience with paragon. I bought a spiral staircase and installed it myself. Vincent helped me specify the correct stair case and railing. The packaging and parts labeling was awesome. Overall quality was top notch.
