Over the last 8 years, I have provided Nonn's with business on 4 different projects (residential and commercial) so I write this review with great regret. With each project the workmanship of their installers has deteriorated to the point where I will never use them again, even their service managers have become grumpy and lazy. Their showroom is gorgeous and their decorators are talented. I would use them for selection choices, purchase the material from them (although somewhat expensive) and then find an installer on your own, however such a maneuver might cause warranty issues. Perhaps the most prudent action is to find a better company who can see your project from beginning to the end to your satisfaction.
