Hello Everybody, Thank you for taking the time to help me out. Im thinking about using a company called Window Masters, based out of Royal Oak Michigan, to replace my windows this winter. Before commiting to the project, I wanted to do do some checking around to see if anyone has had a problem with them. If you have used this company to replace your windows or know of someone who has, I would appreciate your comments. Also, the windows are manufactured by Chelsea. Thanks again for your time.
