I want to stir the pot on this a little and see what floats up...
Has anyone else had problems with Semco windows or doors manufactured in the early 90's?
Of the 12 Semco windows installed in our house, all of them are exhibiting signs of mild to moderate mold infestation and mild to severe rot by the time their 11'th anniversary rolled around. Four of the panes have also vented out and condensation forms between the panes. Many of the lower sashes are not square. Wind causes the sashes to resonate when it blows or gusts above 35 MPH.
The single operable slab French door in our house, also a Semco of the same vintage, is very drafty. In fact, on several occasions, during blustery snow storms, we have seen a small 3-4" drift of snow form on the floor on the jamb-side.
Now, the contractor that installed them way back when never stained or sealed the wood, so that didn't help matters, but I think that poor design and poor quality control were the primary culprits behind the problems we are now experiencing. The rooms in the house that still have the original 1885 windows are literally less drafty than those with the Semco's, even with the storm windows open.
Now, I don't know about anyone else, but I consider any product that falls apart around the time its warranty expires to be junk designed to fail from the get-go to increase revenue stream.
Anyone else have problems with their wares?
