Positive: Quality, Appearance

The quality of the stairs was outstanding. They arrived well-packaged and complete. The instructions were precise. The final product looks great. The manufacture time was longer than predicted.

Positive: Customer Service, Installation, Price

Easy to install stairs. I like the open air look and the speed on what I put them up. It is easier with 3 people. It took us 4 hours to complete the job. The only issue I found on the galvanized coating is there are some sharp areas from the dipping, but not terrible, but I may ask for them to send me a new rail. The rest I am very happy with. It is very sturdy. The customer service is great.

Positive: Professionalism, Punctuality, Responsiveness

The product was exactly as described and arrived in good condition when I was told it would arrive. I was nervous about making such a big purchase from an out of state supplier without being able to see it first but I am happy with the results. The representative I worked with was very attentive and responsive. She even had a zoom meeting with me before I ordered to show me plans of how the stairs would look, what material they’re made of, delivery details, and to answer all my questions. I recommend!
