I used this company based on Yelp reviews and they are the real deal. Read my reviews, I'm not someone who gives 5 stars to everyone. If I'm giving them 5 stars, pay attention. I've used them twice and they've done an amazing job. If you own luxury cars, you need to use them. I only use OEM glass (the original glass that comes with your car when you first buy it) and they have it in stock AND they magically get my insurance to cover it. When I tried other glass dealers in the area( yeah the ones you are comparing them to on Yelp), they would somehow tell me that my insurance didn't cover the OEM glass or that they didn't make that glass any longer or some other b.s. Basically, the other glass dealers didn't want to put the expensive glass on my vehicle and wanted to use their cheap glass they had in stock and lied to me about my insurance coverage. You will see a lot of that from glass guys so beware.
The best part of this company is the person who you speak when you first call. The girls do a great job communicating with your insurance company and they make the transition so much easier. When I called, the lady who answered was very friendly. I gave her my VIN number and my insurance agent's number. She said she would call them and take care of everything. She did and then called me an hour later and did a 3 way with my insurance. They offer that extra piece of service. The techs came to my work and replaced the glass and did a great job.
