 The success of any window manufacturer and window installer is based on only one thing. The consumers' satisfaction with the company's product, price and service. No company is perfect, but we are providing copies of actual recent customer surveys here so that you can make a more informed decision as to which window company is best for your project. 


At Jantek, we consider ourselves a "listening company."   We review each one of our customer surveys as part of our overall effort to continuously improve our products and services and to keep our prices low. We find that our the most valuable input in determining how to maintain our reputation for having the best window, at the best price, with the best service, comes FROM the consumer! No company is perfect... at Jantek we will never stop trying to be.
