if the sealed glass has failed its cheap and easy to replace. in
pittsburgh you make a appointment with pittsburgh window and door,
take the sealed glass still in its frame in the morning, pick up about
4 pm all replaced. getting the frame apart is the main hassle, they do
it all the time so its easy for them.

the hassle is plugging the window while its out, easiest to do this in
the summer.....

my large 4 feet by 5 feet picture window went bad, probably from the
dogs jumping on it. 65 bucks took care of that.

my windows were supposed to be lifetime warrantied but reynolds got
out of the window business and the installing dealer disowned everyone
