    After many attempts to get some quotes, a few questionable quotes. Brian showed up with his friendliness, expertise and fair pricing. Not only did we feel extremely happy with our choice when he left, we were left with knowledge. I am very happy with the timely manner with our appointment as well as the quality of work we were shown. Hands down I am beyond happy. I am going to be tonight knowing that my broken front window. Will soon be the centre of our house. Not only look beautiful but will last for years to come. Thank you Brian for the fantastic customer service you showed us today.

    We just had had our windows installed in Mid August. The installers were amazing....punctual, professional, cordially and very good at what they do. I was very impressed with how they cleaned up afterwards. Brian's presentation was perfect...direct to the point...complete with examples of windows. He explained how the windows would be installed and how they would operate. A very detailed and impressive presentation. I would recommend Sentry Windows & Brian to any of my friends and family.

    I got my windows installed last week through Brian and Sentry windows. I got 8 windows in total and was happy with the service they provided. The installers took their time to make sure that the windows fit right the first time and provided necessary fixes to our old frames. I enjoyed the presentation that Brian did before we decided to go with Sentry. He explained how windows will be installed, how they operate, how they can be cleaned and so on. It was a very detailed presentation and it was quite impressive. A lot of my friends and family have done business with Sentry and Brian. He always comes through with his promises and his install crews are amazing. They arrive on time and do excellent job cleaning up after everything is done, yeah you read that right, they clean up after, vaccuuming and sweeping and so on. Will highly recommend Brian and Sentry Windows and Doors.

    The exterior looks fantastic. So much attention to detail even in the caulking.
