Customer Reviews

"We had an umbrella go through the large kitchen window during a wind storm. The wind was blowing into our kitchen, not good. Preferred Glass, Rachael, arranged for a tech visit in about an hour. The tech was extremely pleasant and very capable. The glass was replaced like it never happened. Thank You Preferred Glass - 5 stars"
