I have never had windows installed prior to this, so I have nothing to compare it to, but I have worked in customer service for years and have to say that the service Provincial Glass & Miror provided was excellent. When I first called to get a quote, they were professional and worked with my schedule to set up a time to come in and have a look. When the guy showed up to have a look, he asked a bunch of questions to make sure I would get exactly what I wanted. The same person then came back to take final measurements and a couple of months later, when my windows arrived(I had ordered them just before Christmas, so the delay was only due to the holidays) the same person installed them. The consistency is nice — no need to repeat anything and no fear of miscommunication. They were in and out in two days and the windows look amazing. They cleaned up locked up after they left each night and even left me a note to tell me what had been done during the day. I’d recommend these guys to anyone who asked.
