I am an owner and property manager of a midtown fourplex. Two windows of one unit had broken parts at the top edge which parts allow the window slip out of it's track for easy cleaning. i called Window City and spoke with Chris in service who said he had the needed parts and so I went to the factory at 6300 Steels W. where I was promptly greeted. Chris took the two windows to the factory line in the building asking me to return in an hour. Amazingly when i did I had two repaired windows. It is rare to have such fine service. My 1930'3 fourplex will need 48 new windows in the next few years. Window City will at that time certainly be asked to quote. Thank-you Chris for your exceptional service. All the best, J. M.
