My 16-year-old Four Seasons Sunroom has a glass pane that shattered spontaneously. It also needs new window crank handles because the existing handles no longer close the windows.
Worse yet, the sunroom leaks at the interfaces with the walls, causing structural damage both to the walls and to the floors. Despite numerous phone calls, emails, two visits to the Orlando showroom, and repeated assurances by a parade of employees that my problems will be resolved, I have not been able to get service or even parts to install myself.
I have been asking for service and/or parts since 2/2005.
I do not recommend this product.
