I'd say middle of the road to a poor experience. Definitely not the attention to detail that I expected. Our original quote was fine, but they didn't get everything correct (hardware color). That's minor (but sadly it all added up as you will see). We had them do 2 shower doors. For the master, the door was installed and after the fact, I was told that the manufacturer omitted the coating. They offered to come to my home to apply it. I opted to have it removed vs applying it onsite at my home (oddly enough, friends that used them said that the same thing happened to them - 3 to be exact - seems like a cost saving tactic). I even got a mistake call from the office saying that the coating was omitted by the manufacturer (call was for another client, but they mistakenly called me). I'm suspicious. None the less, they removed the door, had the coating corrected and reinstalled it the following week. The other shower door was also problematic. Upon install, one of them broke (literally shattered into a million pieces). I think those things happen - either a defect or install issues. The clean up of the shattered glass was poorly done. Very obviously pieces were stuck to the caulking on the wall. After several weeks, I called to see when it would be replaced. They said that the manufacturer was not being responsive to them and that they were going to use another manufacturer. That prompted them to have to come out and remeasure. I was compensated with approximately a $100 discount (which was not communicated until later). Then on the day of install, they never showed up and I had to call to see what was going on. They rescheduled me for 3 hours later that day. Nice people, but a lot of missteps and a lot of effort on my part. By the time it came to pay my bill, I was plain out exhausted. Customer service was poor. Lots of blaming and lots of excuses. Not much ownership on their part. They were apologetic, but they definitely didn't own it. There are lots of choices in this space. I do not recommend AZ Xtreme Glass & Mirror.
Update: they completed the final shower door installation on Friday 8/13. When the installer asked for payment, I said no. He did not leave an invoice and did not have any history. They also took final payment on the first door, so I was suspicious of the amount that he told me. On Monday 8/16, I talked to the office. I was given the details on the discount. I did not pay at that time due to needing to compare my quote to the invoice, but more importantly to ensure that I was not double charged. I don't think they processed the payment. On Tuesday (8/17), I paid the bill in full and Wednesday I received a notice of Lien filed on 8/16. DO NOT HIRE THIS COMPANY!!! THEY COME ACROSS AS INEXPERIENCED.
