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 TalbotTimothy GrahamTimothy Graham ★★★★★ 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 ownerThank you for the post and call out for Dan. Glad we were able to help!!! Bill BeanlandBill Beanland ★★★★★ Bj CBj C ★★★★★ 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,Jim CarsonJim Carson ★★★★★ 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 timeLauren PhillipsLauren Phillips ★★★★★ 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.R StrangeR Strange ★★★★★ Fantastic addition to our cabin! The team was great to work with.Rich FarringtonRich Farrington ★★★★★ 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.Bruce Mears Designer BuilderBruce Mears Designer Builder ★★★★★ 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 MearsJack DoyleJack Doyle ★★★★★ 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.Kuhn Carpentry LLCKuhn Carpentry LLC ★★★★★ 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.Brian BellBrian Bell ★★★★★ Was as advertised. sturdy. fit perfectly. easy to follow instructions. all of the parts included. Looks great.Paul CrissyPaul Crissy ★★★★★ 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.X VOTOSX VOTOS ★★★★★ 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!Charles JacksonCharles Jackson ★★★★★ 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.Steve A. McIntireSteve A. McIntire ★★★★★ 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.Brianna WarnackBrianna Warnack ★★★★★ 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!js_loader

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!
