Glass USA advertises that they offer 24 hour emergency service. They are not kidding. We broke our sliding glass door on a holiday. Glass shattered everywhere. We did not want to have an open area in our house. We were not prepared to board up the sliding glass door and the regular stores were not open to purchase wood. We called Glass USA and they came out a few hours later. They replaced our glass and everything was back to normal. Our holiday wasn't ruined and we didn't have to worry about not having a door at night. I highly recommend Glass USA!
