The double glazing in one or two of our Andersen casement windows is
leaky, as evidenced by condensation and/or dirt between the two sheets
How easy would it be to replace the glass myself? Any tips?
The problem is not the glass, unless you see cracks in the glass. The
problem is the seal between the panes. It's not so easy to do this
yourself; in the factory, they remove the air and pump in a dry, inert gas
like argon or nitrogen before making an airtight seal. Moisture between the
panes indicates a failure of this seal, and you'll need to replace both
panes with a factory-sealed two-pane piece, not just putty in a new pane.
Look in the LOWER CORNER of your windows to find an ETCHING.
Check them all.
There is a manufacture date there ( never knew that ) - write down any
Call Andersen toll free.
Andersen replaced 3 of my 4 windows under factory warranty.
Give them the numbers and they sent it with no inspection at all.
