Our Wisconsin home is 8 years old and the inside portion of the wood windows is decaying. The windows have built in grids and have moisture collection on them even when it's in the 40 degree temperature.
No it's not too much humidity, its a poor seals on their windows. More consumers should complain about poor products and service. My parents have Anderson clad/wood and their house is 45years old without this problem like Marvin windows. Called dealer and said too much humidity, but doesn't frost up on their center fix panes.
Had humidity checked and wasn't the problem.
Poor customer service. Never recommend Marvin.
Reason of review: Damaged or defective.
Monetary Loss: $10000.
Preferred solution: Let the company propose a solution.
