I purchased 3 spiral stairs and Steve Cohn walked me through the process. We just installed the first stairs, and the quality of the workmanship and clear instructions pleased my men. They are looking forward to installing the next ones. Fantastic service and products
Second to literally NONE.Seek no one else for your stair and iron, etc needs. What a great business and products. Been using them and them only for almost 30 years. Great family and superb people and product.
My parents purchased spiral steps from this business over 30 years ago. I recently purchased steps and railings for my home, and I can tell you I am very happy. The staff were all extremely helpful from beginning to end. The sales team was very knowledgeable and always answered my phone calls, and assisted me even after the purchase with questions and concerns. I am local and was able to go onsite to puck up my order, and everyone was very friendly and helpful.
Fantastic company to deal with, they worked with our clients Neds and kept us informed the whole time.We had a problem with the shipping company losing some parts and they took care of the situation straight away, highly recommended!
Steve is a great guy!
The company is excellent. Quick responses to questions. Pretty easy to order. Took only a week & a half to get to the point of delivery? It arrived in excellent shape - due to superior packaging. Nothing was left to chance. There wasn't a mark on it. Detailed instructions were included Plus a phone number to call for help. There even was a video available to watch. It is installed. I LOVE it. The stairs are very strong. Doesn't make a peep or rattle going up or down. I am just tickled to death !!
I am a long- time customer of the Iron Shop having bought several sets of spiral stairs as a General Contractor. The products are superb, craftsmanship excellent and service team are beyond expectations as efficient and personable.There is no better source or team for these products.Sharon P Talbot
Dan at The Ironshop was the best. He helped me from start to finish. He helped with ideas and suggestions, calculating all the specs and answered questions during the installation. They even included stamped blueprints that helped expedite my approval through the city.I would highly recommend The Ironworks for your spiral staircase too.
Response from the owner: Thank you for the post and call out for Dan. Glad we were able to help!!!
We love the new spiral stairs. Install was easy, good quality and the customer service was very helpful. I tried two other spiral stair cases from another company because they were cheaper. This proved to be a mistake as the stairs were poor quality and some items would not fit together and the customer service was nonexistent. Therefore, wound up returning those cheaper stairs and purchased spiral stairs from The Iron Shop. I am glad I did. I highly recommend these stairs to anyone and definitely make your purchase at The Iron Shop. You will not regret it.Thanks for everything,
During a major barn restoration, we had a last-minute complication with a traditional staircase that was designed for the barn to navigate a 15-foot-high level change. As soon as I asked our contractor if we could drop in a spiral staircase to solve the problem, they immediately suggested The Iron Shop as a company they had worked with previously and were very pleased with your work. The turnaround time was amazingly short, the application far exceeded anything we had previously planned, and the appearance of a contemporary staircase placed in our 150-year-old barn beside a hidden elevator shaft was stunning! We added repurposed barn wood to be used as treads on the stairs and the spiral staircase looks like it's been there the whole time
Could not have been happier the day our beautiful spiral staircase was installed and again close to 6 years later. Our staircase is beautiful, sturdy, saves backyard space, and is used routinely by our entire family. It looks as good today as the day it was installed. The experience designing our staircase with the staff at the Iron Shop was wonderful and the assistance they provided our contractor during the installation was appreciated. We recently had to email this wonderful company as one of our landscapers slightly scratched our handrail and we wanted to touch up the scratched area ASAP. Unfortunately, the bronze color powder coating we needed was discontinued by the manufacturer but this didn’t stop the Iron Shop employees from going the extra mile to provide excellent customer service. They quickly located a few cans of the discontinued color in their shop and offered them to us. Now how many companies would even bother to look? If you want to partner with a company that is professional and customer oriented then this is the company for you. And did I mention they make a great product? We are so pleased we plan on installing another Iron Shop staircase (or two) in our retirement home in the next few years.
Fantastic addition to our cabin! The team was great to work with.
Communication on order and responsiveness was excellent. Spiral stair was delivered as predicted and installation went very smoothly. They were very patient when we were trying to reduce the cost of the stair (budget job). Many kudos and no complaints.
I'm a high end builder at the Delaware Beach. Iron Shop's cost is equal to others but their product is superior. I use the Iron Shop for all of my projects. You can see more of their work on my website. Bruce Mears
I have bought and installed 7 spiral staircases from The Iron Shop. Every detail is top quality and that makes installation so easy. Every customer was happy.
Super strong and easy to assemble spiral staircase. Arrived via truck on time in several boxes. Good communication with project managers and support staff when I had questions.
Was as advertised. sturdy. fit perfectly. easy to follow instructions. all of the parts included. Looks great.
Purchased a 7” diameter aluminum multiline outdoor spiral staircase which was assembled by The Iron Shop. It is larger than most of the pre-fab alternatives but worth it. It isn’t inexpensive but the quality is first rate and a distinctive addition to our home.I picked up the staircase at The Iron Shop manufacturing facility. Although the staircase only weighed about 400 lbs, its size and the chance of damaging it during a 400 mile trip to south-central Virginia made loading somewhat challenging. The manufacturing team that constructed it customized a stand that was bolted on the trailer. The entire team, and several other shop workers, pitched in to ensure safe transport; it wasn’t a cookie-cutter solution! Their pride in their work and ensuring customer satisfaction was clearly evident!The transit took about 9 hours with speeds seldom greater than 45 mph. Travelers were definitely interested in my cargo, appreciated my journey and repeatedly gave me 2-thumbs up after they figured out what they saw.Installation took about 2 days and most certainly meets our most optimistic expectations.
I have had an Iron Shop spiral staircase for over 20 years. I love this staircase- both form and function are superior! I lost a few screws and a bracket and called Iron Shop after 20 years and Dan (Thanks Dan) was kind enough to send me some screws and a bracket at no charge. Thank you Iron Shop! Happy New Year!
Overall great experience. Iron Shop helped me design a narrow spiral staircase for a tight opening up to a finished attic, the stairs were delivered on time, it was fairly easy for me to put the stairs together (and much easier than expected), the stairs look great, are very solid / sturdy, and were priced on the lower end of what I could find.
Beautiful product that was straightforward to assemble (my first time). When I had an issue (my own duh), the team addressed it quickly and professionally.
Ordered parts for my spiral stair kit and the customer support has been above and beyond. Dan sent me some spare parts immediately after I emailed him that I damaged a part during installation! I’ll definitely be ordering my staircase upgrades in the future!
I bought a custom, all-aluminum exterior spiral staircase to connect my back door to the patio, one story below. The weight and quality of the stairs -- pole, treads, balusters, handrail -- is impressive; heavy-gauge aluminum, precision cuts and welds, all fitted beautifully. The kit includes a huge amount of hardware and a 75 page manual with inserts. The whole job was shipped in one giant box, about 400 lbs, to my driveway. Note, this is not a DIY installation. I hired an experienced builder to build a landing, assemble the staircase, and connect it to my house. One critical assembly part was left out of the package, but The Iron Shop remedied that with an overnight delivery. The production team at Iron Shop has been timely, responsive, and easy to work with. I am happy, overall, with the staircase -- it's high quality and it meets my needs.
I bought a powder coated spiral staircase 6 years ago for my ocean front home. I have had to replace and maintain so many things due to the salt air, such as most of my outside lights which all corroded, even though they were rated for marine environment, hinges, and locks. I have had to repaint the front of the house, doors, the garage door, but NOT the spiral staircase. If I cleaned it, it would still look brand new. Very high quality product. I highly recommend. I also have a spiral staircase at my non-beach home. I chose the standard paint finish and have to re-spray paint it every 3-4 years. Still great. Everyone near me (in the city) has the same issue with their metal balconies and stairs. I do recommend you pay more and get the powder coat finish though, I would if I could do it again.
Response from the owner: Thank you for the great review. Please email info@theironshop.comWe would like to get more information if possible.
I dealt with Rachel, who was very responsive and customer oriented. She was very professional and took care of couple of missing parts very promptly. I would highly recommend this company.
Even though they can't help me on my project, they were nice about it👍
I had a great experience with the team at The Iron Shop. Rachel Mumbauer was a pleasure to deal with. She was quick in response, and very knowledgeable in her chosen profession. She walked me through the process of designing a custom spiral staircase for my backyard. It fit perfectly. I’ve worked construction for over 30 years (commercial/residential) in NYC and on Long Island. I was truly impressed by her eye for detail. I wouldn’t choose any other company for a staircase after my dealings with Rachel and the team at The Iron Shop.
We purchased a spiral staircase from the Iron Shop to compliment our Trex deck. The Iron Shop's customer service is absolutley fantastic. I worked with Steven and he helped me with this project from start to finish. I had a ton of questions along the way, and even during the installation process he was always available to make sure things were going correctly. Our new stairs are the envy of the neighborhood! The craftsmanship of the stairs was unbelievable. Every single piece lined up perfectly, and every hole was precisely where it needed to be. My son (age 11) and I completed this in just over 2 days. The end result is something we can be proud of for many years to come. Thank you Steven and the Iron Shop for helping us.
Response from the owner: Than you for your business Jason, and for sharing your experience! It's great to hear that not only was the install successful but a family project you can proud of for many years to come! We'd love to see pictures if you have any! Thanks again!
Vincent was so helpful in helping me secure replacement parts & hardware for our very old spiral staircase. Such a great experience!
Response from the owner: Thank you for your business and for taking the time to appreciate Vince like we do!
Response from the owner: Thank you Hailey!
We have been in love with our spiral staircase for 12 years now. It's so well made and a focal point of our house. Today I needed a tiny spare part and the salesman dropped it in the mail pronto without hesitation. Great company, great product!
Response from the owner: We are so happy you love your spiral staircase. Thank you for taking the time to share your customer service experience as well! We would love to see photos if you have any of the spiral in your home 🙂
My wife and I bought a spiral staircase from Dan at “The Iron Shop” and could not be more pleased. It came out so very well and is a work of art. Not only was Dan extremely knowledgeable, but also very helpful and generous with his time and expertise. He showed a great deal of patience in dealing with our many, many questions. In retrospect, this was a perfect choice for our needs and well worth the money that we paid. I feel much gratitude when looking at our beautiful spiral staircase that needs no maintenance and will outlast both of us.
Response from the owner: Thank you for taking the time to let us know how much you enjoyed your experience! If you have any photos you would like to share of your spiral staircase - we would love to see them!

I contacted R&L (shipping company) regarding delivery late Friday morning, they said they were going to try to get it there today between 11:00h-16:00h. They dropped it off Friday at 12:00h. FRIDAY!! Same day! 300+ pounds as far to the side of my driveway as possible so they didn’t block traffic. I called your company several weeks ago late on a Thursday afternoon, got a Rep that late in the day, and we had a final order by Monday AM. I was contacted almost immediately by customer service — yourself I think — and then one of the fabricators. “3-4 weeks” for fabrication was barely three weeks and it was in my driveway in 22 days from my first call! I’m a small business owner myself — and I’m jealous!! You guys are GOOD! Not a single weak link along the entire chain! The stairs are already up! It’s a FANTASTIC product!! But it’s the service and the efficiency that I’m raving to my contractor about! Just a great job from top to bottom! Thank you!

It was simply night and day how different my experience of having a spiral stair put in was after I switched to The Iron Shop. The first company I tried left me with unusable stairs and seemed totally unwilling to fix their mistake. The Iron Shop walked me through the entire process, gave me the right advice, and their installer did an outstanding job putting it in. I couldn’t be happier with the finished result. It looks stunning and fits the space perfectly. I give them my highest recommendation!
