    I had 24 triple pane windows installed and was very happy with the installation. The windows are energy efficient and noise reduction. Great local company to do business with. Dave was very knowledgeable and made great suggestions to improve our home.

    Jantek Windows provided excellent service, from first time we walked into the showroom and met with Mary to the installation with Joe, each step of the way was easy and comfortable. Questions were answered clearly, phone calls were returned in a timely manner and problems resolved quickly. We will be using Jantek Windows again in the spring for a new slider. It is nice to do business with a local company who cares about their customers. We have recommended Jantek Windows to friends and family members, because of their quality products and customer service.

    Jantek was fantastic! The service was great. My installer Joe was meticulous in fitting my new windows and making sure they were well insulated. On top of that he was very courteous and personable. An error in measing my bedroom windows had been made, but no worries. Dave nade sure the rush order to remake those two windows was processed so that the remade windows were ready for installation as soon as the other eight were installed. Great service and price from a local company that handles everything in house. Who could ask for anything more??? Thank you Jantek. I can now open my windows!

    Jantek replaced all of the windows in our house. We chose the triple glazed windows because we wanted sound reduction and insulation to help reduce our heating/cooling bills. Jantek were friendly, informative and well priced. Their installation was timely and efficient. We waited a while to write this review because we wanted to see our bills and whether the sound reduction worked, it did! Thank you to all the Jantek crew from the sales department, manufacturers and installers. You’d get more than ⭐️⭐️⭐️⭐️⭐️ if we could!
