We were looking to secure the glass on the glass of our double doors at our main entrance. We spoke with a few companies. Not only was superior's pricing better, but they definitely seemed to know what they were talking about. Explained in detail how the product would be installed and why it needed to be installed that way. The day of the install they were running late, but did call to tell me that they would be an hour to an hour and a half late... not a problem. Install was quick and clean. Would recommend these guys again. Pro team.
