    Jackie was amazing and always a phone call away to answer questions. The guys who did the install were very friendly, helped me remove my blinds because I didn’t have the right tools and they did an awesome very efficient job. Some dry wall got chipped off when removing one of the windows. The installer came to me right away with the options to fix it and all was solved. It was really nice to go to the warehouse and see the product before buying. We were only able to afford 12 windows so far and have 28 to go and will definitely be going with Sentry for the remaining ones

    I came into the process not knowing a thing about doors and after experiencing some other local window and door mfgs.in the area and after hearing Sentry's expertise on 570 News Talk Radio, I called to have a representative attend my residence. An Appointment was arranged to my schedule (supper time) and Brian attended. He was well prepared and provided me with the leadership and experience I was looking for when selecting a front door. Their customer service was superb. Thanks

    Although you may find cheaper prices while window shopping, when you breakdown the quality of product, customer service, and quality of install crew you really need to work with the Sentry Window team! We did 19 windows and 1 slider and they took the time and effort to CORRECTLY position all the windows to make our home safer (we had mold due to incorrect install fit and finish) and warmer for my children. Andrew and his father, well you can't ask for a better install crew! Thanks Sentry team!!

    Jim Lee Had a Patio door and an Entry/Storm door installed. Excellent Company to deal with right from the sales rep ( Alan ), the office staff , and the installer ( Abe + assistant ). Every question we had was answered, every last speck of dust was cleaned up after completion. Very professional!!! The finished product is a 10+. Will defiantly be giving them a call in the future ::)))

    We just had a door installed today and it looks great. Brian made an excellent presentation and he knows his products very well and his passion is palpable. The installers were very professional and answered all of my questions. We would recommend Sentry Windows to others and would likely use their services in the future.

    I have to start by saying that every time my husband and I try to do anything around our house we ALWAYS run into a dilemma. Even something as simple as replacing a light fixture has given us nothing but trouble. When we discovered that we needed to replace our front entry way due to a lot of rot and a lot of heating/cooling being lost at the front door we were quite overwhelmed because we knew it was no doubt going to be a HUGE undertaking and with our luck we knew something would go wrong and it would be a hassle. We called a few places and decided on Sentry based on their exceptional reviews. We met with Brian and his high energy had us on board in no time! He was extremely knowledgeable, friendly, funny and made us feel very comfortable. He went through the whole process and explained how it was going to happen and showed us the quality of his products. When the day finally arrived for our door to be installed I was shocked when the crew not only showed up on time but 20 mins early! They were all friendly and hard working and got straight to work immediately. During the whole process they were courteous and mindful of my house and their surroundings. We joked throughout the day and I felt like we were old friends catching up, that's how comfortable they made us! Everything was done perfectly and professionally. My family could not be more pleased with how everything turned out! When it is time to replace the windows at my home I know exactly who I will be calling! Thank you Sentry, Brian and the crew, you guys are amazing!

    When you deal with Brian and Sentry you get an education in windows first. Brian saw my window problems as a challenge. He discussed our options with us thoroughly so we were able to make an informed decision. Even in the cold and snow and rain, the team worked hard to get our windows in and finished. Very, very happy with the result. Wish all contractors were this professional. We highly recommend Brian and the Sentry team and have already recommended them to many friends, neighbours and family members. Thank you very much, Amy and Jim Miller
