I would like to tell everyone about Sears windows. DON'T BUY ANYTHING FROM SEARS. We purchased windows for our house after a tornado in 1985 from Sears and had a LIFETIME WARRANTY. THESE windows are thermo pane type with dual panes of glass. After only a year the windows developed an air leak which resulted in condensation and dirt getting in window. We called Sears and a representative came out took a look and order the new panes and had them installed. No probelem, then a few years after wards at least 5-6 windows had the same problem. By then Sears had turned over the windows to great lakes construction, they referred us to them and were told that the windows didn't have a lifetime warranty. that the most they would do was supply glass and we would have to have someone install the glass. Mom for the last 4 yrs. have been on the phone at least every week up until she passed away. And Sears told us to get ahold of great lakes because windows did have lifetime warranty. We showed the paper work that says "LIFETIME WARRANTY" sO me and Dad have decided to just go get windows from Home Depot or Lowes or somewhere else, anywhere but Sears. They don't stand behind anything anymore. They treat their customers like dirt and wonder why they are going bankrupt.
