I have never had windows installed prior to this, so I have nothing to compare it to, but I have…read moreworked 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.

I would give them 6 stars if I could:) I had a positive experience, the windows are great and we no…read morelonger have drafts in our home! Their service was actually what I would call "customer service"- a rare trait these days. I recommend them 100%! The one thing that really stood out to me is that they were willing to make 5 trips to my home in the course of this: 1 for the initial quote;1 to sign the paperwork (as in, they let us think about it and came back when we were ready!); 1 to do a confirming measure (I really liked that they did that!); 1 to install the windows and doors; one to finish the job. Please note- each trip would have been approx 90km EACH WAY! Thanks for being so great! We are very satisfied with this experience.

The main reason I went with this company was they were able to provide an estimate and leave it in my mailbox. The price was fair as well. The roof was installed and ready for me when I got home from work. They even added a couple extra vents at no extra cost. The area was clean as if they never came at all (apart from the fancy new roof)

Now it is a pleasure to look out and actually be able to open and close with ease Mat and Jeremy were polite and very professional with all the installation process and did what we thought a 2 day job into a one day job. The old windows came out easier than anticipated and absolutely no mess left behind. Andrew the sales rep was also so kind and generous with his time as we are elderly and he answered all our questions completely and even came the day of installation to bring coffee for us and the workers.
