Our realtor recommended Papagno's when we were thinking about putting in quartz counters in our kitchen and we wanted to make sure that we had the best fabricators. We ended up switching to granite but stuck with Papagno's and are we ever glad we did.
Papagno's does something that no other fabricator does (that I'm aware of): they do miter cuts on the edges of their granite which allows the edges to continue the pattern all the way through the edge. It makes the edge virtually invisible and looks super nice. In addition, when they put on a backsplash, they do the same thing to carry the pattern of the marble through from the countertop to the backsplash. The effect is amazing.
We also chose to have our the surface of our counters "leathered" which takes the polish off the slab and makes it have a texture. It really is a nice effect, and I'm not sure that many other fabricators have the machines to do this.
The installers were amazing and really took care to protect everything as they were doing their install.
I honestly couldn't be happier with the results. I would strongly recommend them to anyone looking for new counters.
