 Trustindex verifies that the original source of the review is Google. I spoke with Sierra today and she told me they were pretty booked out on their schedule and I wanted something done asap. So she was kind enough to give me two other company recommendations, which I thought was so cool. Top notch customer service with Ridgeline Glass, and if I ever need glass repair in Denver in the future, I will definitely be calling them back. Thank you Sierra!

 Trustindex verifies that the original source of the review is Google. Horizon did a great job in replacing a window.  We had two other companies tell us the individual window in the cluster could not be replaced, but it all needed to be replaced in its entirety. Horizon was able to match the glass and replace just the window we wanted at 1/3 the cost of the entire set.
