Jessica Rice
Just got new windows installed and I am very impressed of the professionalism these young men display. From the start of my quote to the completion of my installed vinyl windows, everything exceeded my expectations! Also, they came back to do my trim in a timely manner. This crew goes above and beyond their workmanship. We are very satisfied with our windows and trim and absolutely recommend Titan Glass to anyone looking for new windows and installation!
Pennie Thompson
These guys were great. We needed to update our windows on an older house. We needed non standard sizes. They got them ordered and installed quickly. They were great at communicating timelines and we are very happy with their service. We would recommend them to anybody needing any kind of window work.

Zach is one of the most professional and competent vendors I’ve used. I had a break in a very large storefront window and not only did he repair it on time and expeditiously, he discovered significant problems with other windows that he repaired very reasonably. Other vendors who bid on my project hadn’t even noticed the issue. I would not hesitate in using Titan Glass again, and again. (Just hope I don’t have another broken window anytime soon (:^) )
Brian Hopkins
I give them 10 Stars! Fast, honest, efficient, affordable, friendly, more than capable. I'm recommending Titan to anyone who needs any kind of door or window work. They can fix just about everything! Arrived to repair one glass door and fixed a total of four doors in the house. Great company--and they even answer the phone and return calls!!
Nicholas Carlson
We had an accident happen at 7 in the morning on a Saturday and needed a window repair fast. Zach was there in 30 minutes and got the job done. Highly recommend!
