Sometimes customers order there windows cleaned and are unhappy with a certain type of
window that is still ‘dirty’ after we clean them. On old windows, the seals will deteriorate and
cause the gas between the two plates to escape and moisture to come in. In this case, the
windows will not be as efficient in keeping heat or cold in, and will appear foggy or
condensated. There is nothing we can do to make them improve at that state. We don’t like to
be the bearer of bad news, but it is necessary to point out what is happening with their
respective windows and let them decide if they would like to replace the panel. There are a few
companies I’d recommend, so again, I’d be happy to refer you to them.
