I agree I wish I had look them up before letting them enstall the windowst in my home. I too was told it would take about 6 to 8 weeks to have the worke done 14 weeks later and after several call to them (done of which were return Untill I threating to call the better busniness bearau) finnally in July they did install the windows, However one of the windows was defective as of September 7, 2011 they still are giving nothing but a lot of excuses on why the window have not be repaired. when I call them they promise to call back ,but never due. I wish I could have given them a minus rating but the computer would not allow me to do so. There or alot of good companies enstalling great windows, that provide great customer service, However Window concept of Minnesot is not one of them. Please do your Homework, look around, I hope you do not MAKE THE SAME MISTAKE I DID, AND LET WINDOWS CONCEPT DO ANY WORK FOR YOU. Thier customer service is the worst around.
