All my windows were installed in 2005 by Atlantic Window & Door Systems Inc,, 1680 Courtneypark Drive East, Mississauga, ON L5T 1R4. The contract says Lifetime Warranty.
All the windows had rusty hardware problem and the company sent people to fix almost all of them in 2009. I just found one windows hardware is still rusted and try to call the company since the end of May.
I heard the company has filed a bankruptcy. All there previous phone numbers were greeted with Atlantic Green Home Solutions.
