  Almost a year later and I'm still finding nails and trash in my yard from when the windows were replaced. Most of my windows will not stay open the tops fall down like they are too loose. There is multiple spots where caulk was missing that I fixed myself. Looks can be deceiving I was impressed at first but after the honeymoon was over I'm seeing the true colors. You get what you pay for BE CAREFUL CHOOSING THIS COMPANY

  Jantek did a great job replacing 9 of our windows. Dave was very knowledgeable, as he himself used to be an installer. He was super patient in answering our many question. He even allowed us to poke our heads into their factory so we could see how the different grid options could look on the window size we had ordered. When it came to install, it was a two-day process with two people. All nine windows were completed the first day. The second day, that same two-person team replaced our old patio door. It's only been a month with our new windows and door, but we are very happy with the install and quality of the products so far. Only minor imperfection is that one of our windows has an incomplete beading of calk around it. But we can do that ourselves since it's on the first floor. Other than that, we feel everything looks and operates very nicely!

  We are new to South Jersey and Jantek was referred to us by a few people. We were not disappointed. Dave was very professional and personable and clearly explained the window process to us. The installers were amazing. Got the 13 windows done in one day. The clean up inside and out was also very much appreciated. Not all companies do such a great job. The windows look amazing and are very easy to use. We love them. Thank you Jantek. Highly recommend.

  We had a great experience working with Jantek to replace all our windows, including an octagon shape and two basement windows. From the beginning, they were easy and pleasant to work with. We visited their showroom and really appreciated being able to see the windows in person and speak with knowledgeable employees who took the time to answer all our questions. Jantek’s pricing was the best out of all the quotes we received, which made the decision even easier. We also liked that they manufacture their own windows and stand behind their work with solid warranties for their products and the installation. Jantek was very easy to work with when it came to our HOA requirements, helping make sure everything met the rules and guidelines without adding stress to the process. Overall, the entire experience was smooth and professional. We are very happy with the results and would highly recommend Jantek to anyone considering new windows.
