Hey Texagpilot,
What kind of warranty does Jeld Wen have?
I am in the same boat. We just put our house on the market and have decided to fix our windows... same thing, broken seals and fogging up inside. About 5 windows (10 sheets of glass). First we got quotes to replace the whole window (frame/glass) and that was about $4200. Then got a quote from a company to just replace the glass... that was about $2200.
What a bunch of crap these windows are, we bought the house new 15 years ago. Started noticing the fogging after about 12 years or so. Several of the window companies I spoke with said the same thing "these gas-sealed double-pane windows are a good concept and work well up north, but cannot handle the heat/humidity down here."
I can't find any manufacturer info on any of the windows. May have to call Plantation Home and see who they used for windows back in 2002 in the Houston-area... though I'm sure I am well past warranty.
