The first removed the window, it was quite a challenge as my truck is old, and that window was stuck on. I am actually surprised he got it off in one piece, despite a crack down the length that had a 1/4 gap. The tech found rust damage on the truck. He explained why it was bad and why he could not proceed.
The second come out after repairs were made and installed the window.
For both the Techs, I was able to ask questions and the Tech was able to answer them, or get me in touch with someone who did. Both were clean, fast, really efficient, and happy to do the work. Form observing both technicians and seeing the similarities in the mannerism and professionalism, I could tell both were projecting the company culture loudly.
I am impressed.
