Agree with all five-star reviews—these folks at Stairs.com are highly skilled specialists! We ended up with a beautiful, solid staircase remodel and our home looks new. I had been searching for stair specialists for over a year to fix our badly remodeled, wobbly staircase. What a difference true professionals make. Gina visited for estimates, and the work was done in about 10 days. This is a true team of skilled professionals with amazing personalities. Recommend 1000%!

I had a wonderful experience with stairs.com, from the website to customer service to the final delivery. Kaitlyn was very helpful in sending photos of possible options and giving great advice. It felt like Kaitlyn wanted my project to be a success just as much as I did.
