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.

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.

Within less than one year from having a new front door installed by Dans, it's been nothing but problems . The wood around the striker broke shortly after install, I called them and they talk to you like you've never used a door before , they put all the blame on us for being too aggressive opening and closing the door and the project manager constantly had to leave multiple times for personal problems (which has nothing to do with the customer- we all have problems in life) ) - all this with a lifetime warranty on the door, which they point out when purchasing but they don't honour it. The hardware on the door never stays tight so every month I've have to re tighten all the hardware (which is absurd ) and they said they would try to fix the broken wood by the striker but they never return your call or show up - I'll be replacing this door before it's even 3 years old because I'm sick of the maintenance required to just keep it operational . Worst customer service I've ever had . Save your money and buy elsewhere. Buyer beware I only gave one star because I couldn't give zero stars

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.

Absolutely incredible service from the initial first visit to the install of our new front door and…read more6 windows. First we had a gentleman, can't remember his name, who was patient with us while helping choose our door. He knew the right colour that would go with our brick and also the glass design that would work best for our home. We trusted his opinion and he was bang on. The windows were also replaced in the front and he chose a colour that would compliment the door. When everything was installed, the installers were courteous and professional. They were very meticulous about the finishing and did an awesome job cleaning up after. We are totally impressed with them. Highly recommend.
