Do you come out to measure the windows and doors?

Yes, we schedule a measurement appointment after you sign the contract and submit the deposit. The quoted price remains unchanged unless we discover structural issues, such as wood rot, during the measurement process.

We had a great experience with Jantek Windows. It was important to us to support a local small business, and we’re glad we chose them. Dave, our project coordinator, was helpful throughout the process, and installers Tom and John did a great job. We’re very happy with our new window and would recommend Jantek

So happy with my new Jantek windows. The highlight was my new bay window. Not only did they do a great job, but I had 4 major window companies give me estimates, and Jantek beat the other three. I was also confident because of their very good reviews.

We had a great experience with Jantek replacing our nine windows and sliding glass door. Their pricing is reasonable, and we love that they manufacture their own products and offer substantial warranties on both the products and the installation. Visiting the showroom was a huge plus, and they easily provided the necessary documentation and photos for our HOA. The installation team was efficient, clean, and knowledgeable, completing the entire job in just one day. The whole process was smooth, professional, and stress-free. We are thrilled with the results and highly recommend Jantek!

I liked that this was a local company with a location that we could visit and make our final selection. The sales process was better than other companies who felt very pushy and best price. Mike and Jay were great installing our windows. Very professional and on-time. Love our windows - triple pane with easy open/close. Thanks Jantek Windows!
