Window Depot USA

Description of Work: On 9/27/07 I hired Windows Depot USA to install what were supposed to be quality windows with a lifetime warranty. The warranty covers everything except acts of nature, such as hurricanes. The windows are 2-ply glass with argon gas between them. These windows are supposed to cut costs of energy use significantly (30%) and they have not. I even got a pledge that states a reimbursement of $500 or difference between preceeding year's fuel consumption and fuel consumption at time of installation, whichever is lower. I have not even tried to pursue that. I had all windows replaced: 10 total plus sliding glass door. A year later, I had Windows Depot install another window where they was none to add more light, for a total of 11 windows. Several months after initial installation I started having problems. 2 of the living room windows hazed over. It was explained to me that this happens when the argon gas leaks out. Windows Depot replaced these 2 windows. A year later while trimming grass I noticed the sliding glass door was cracking until it consumed the whole door. Windows Depot told me the sliding glass door was not covered under the warranty. I have a limited glass breakage warranty that states if glass should break or crack in purchased windows as long as you are the original owner, Windows Depot should provide a new sealed glass unit at no charge except for shipping & handling charges. I studied the contract & did not find any exemption for the sliding glass doors. Windows Depot & I argued about this for 4 months. Finally they agreed to replace the sliding glass doors at no cost. A year later the same thing happened. I called them & told them I would pay for the new doors, but it still took them 4 months to repair it.
