My sales rep Peter was awesome to work with and very helpful. I will definitely purchase from Paragon Stairs again. Although our handrail was damaged by the freight Co. and a couple minor missing parts Paragon's customer service was good . comments on the stairs!!! Had them up in four hours (less railings) and they fit perfectly.Definitely not light weight junk either. Much like your well opening, your diameter may be defined by your placement of the stair. You need at least 44”x44” opening because you’ll need two extra inches for your fingers to travel along the handrail as you walk up and down the stairs. I was scared to order a set of steps from a online seller. My contractor had to call them up a couple times with questions and they were prompt to resolve the issues. The instructions were easy to follow. Great stairs & they fit really good! Dealt with malissa she had me sent picts of site of install and sent me precise shop drawings of proposed stairs with estimated price i was 100% sure that not only they would fit but also with the best layout possible she made it very easy the whole process and job came in. The whole process of dealing with Paragon was a good one. Customer service was outstanding. Call for your free consultation and pricing. The product is easy to traverse and has withstood the tough coastal conditions it is located. The stairs were high quality. My contractor put up the stairs nicely nudge against the wall. Great Quality. quite simple to install - it took myself and another guy about 6 hours.There was an issue with the shipping cost, it was going to be more than they initially told me but they honored the original price and covered the additional cost.They were very professional and easy to work with, I will reuse paragon stairs next time I need to order/install a spiral staircase. Great quality product, easy to install. The aluminum hand rail was the hardest. We just finished assembling the second staircase I’ve bought from Paragon. the tower was up and usable in a few hours. I installed my spiral staircase by myself, I had never. Very high quality and the kind of sturdiness you want to feel going up and down the stairs. The stairs showed up when they were supposed to and the packaging was great! the main column will need to be painted to match the finish of the stairs. There were a couple of issues that i had to contact the company about; the first tread was supposed to be shorter by 2 inches to account for the base. The only thing I Wish was more detailed was the instructions. Seemed like there should have been another step than was estimated/shipped and no support available on the weekend when we were doing it. The people at Paragon were very helpful, especially when purchasing an all aluminum stair for our house near the ocean. We did have to keep on them for, updates .. but considering them being shorthanded , due to Covid-19, They came thru!We love our new stairs with Oak treads!!!!! That Brett is awesome! Thanks Paragon. They did it all for me and very quickly too! If your project includes a hole in the floor (likely a round hole for the round stairs) that calls for a spiral stair you will want to pay close attention to our well opening size dimensions. We are very happy with the product. I was given multiple answers none of which were correct. Our SMA certified team is here to help you with each design decision to ensure your stair meets your budget and specifications. It was the only spiral stair company that kept some products in stock. My only bump in the whole process was the shipping company which was out of my control, hopefully New Penn doesn’t drop the ball for paragon with anyone else. I worked with Joe Schikal directly and he went above and beyond to ensure that I had a positive and smooth experience. help lift it onto the post and then hold it place while I bolted it to the deck. They're very sturdy and good looking. We never had any questions or doubts, after talking to them. Ironically, it was on the first tread. the design specs where spot on and the installation was relatively easy outside of stretching and bending the stair rail.
