We had a great experience with Crestline Glass. They came by and adjusted/serviced our sliding glass doors and made recommendations on repairs. Paul was prompt, knowledgeable and professional. So glad that Crestline Glass is on the mountain and has such wonderful customer service!

My shower doors were out of alignment after so many years, and were scraping. Scheduling with Crestline Glass was very easy with one phone call. Doug came out and fixed the problem. His professional, friendly service was awesome and much appreciated.
