    My wife and I met with Brian who spent all the time we needed to be comfortable and confident with the order we placed. All our questions were answered with confidence and clarity. The installation went as expected and one thing that stood out was the respect and care the installers had for our home while they worked in it. The windows and door are everything we hoped they would be. It was a great customer experience and I would have no hesitation to recommend the same level of service to any of my friends or family.

    This is the second home that I have had windows installed and my first time using Sentry. Love the windows! The installation crew was amazing and very friendly and polite. Definitely a better experience, and I believe a better window, than the company I used the last time. Overall I can say that Sentry exceeded my expectations and would recommend them to anyone.

    We just got our windows replaced by this company and i cant say a bad word. The guys are efficient and pro at what they do. They pointed out some issues that we had with the roof and fixed it on the spot. They clean up the site when they are done and vaccuum all the floors and carpets inside the home. They are polite and pleasant to talk to. Windows look great and they always stand behind their workmanship. A+!

    The new slider door that Ken suggested is simply perfect. We have so much more natural light in our kitchen and it is so easy to slide...definitely not the sliders of the past. Everyone who walks into the kitchen notices the difference right away. The installers were courteous and amazing. They installed the door on an extremely hot summer day and they worked tirelessly to get the job done as quickly as possible. Thank you Sentry Windows and Doors, we would never hesitate to recommend you!

    Initially we had some confusions and were dissatisfied with service. However after expressing our dissatisfaction, Ken from Sentry contacted us and had it all sorted very quickly. The job is not complete yet however I have full faith it was be done correctly.

    Absolutely wonderful. Had to get 8 windows replaced. Had 5 companies give me their quotes. Some were cheaper but not experienced. I chose Sentry Windows because when receiving our quote the sales rep went through everything. Even showing how the windows were made, installation etc. Not like some of these other companies who just measured then give you a quote. They delivered and installed the windows within a timely manner. The installers were prompt. Big issue for me! I hate waiting for people. They showed up exactly on time, were very courteous and respectful of my belongings and pets. They didn’t rush the jobs either. They took their time to make sure each window was properly installed. Once finished they even vacuumed my staircase ( which really was more my mess then theirs lol). I would highly recommend them and will use them in the future.

    Jake, Andy and Christopher were excellent in both the customer service and installation ends. They answered all of our questions and did all of the little extras that make for a quality installation. I highly recommend them for any door or window work.

    Excellent service from the first visit in February from Ken. Six windows and two over sized sliding doors installed in June. The two installers were friendly, professional, neat and tidy -- and always on time. Great job. We had a couple of questions post installation. Ken came here himself to answer those questions and to ensure that we were satisfied with the end product. We highly recommend Sentry.

    Our experience has been great with Sentry windows. The Professionalism of all staff we've encountered and especially our install crew has been oustanding. We love our new windows and doors and I would recommend Sentry to anyone.
