I have a problem that arose on me and was wondering what kinds of experiences are out there.
I decided to wash my windows, on the outside, as this was a chore I neglected for a couple of seasons. I have Pella Designer III Windows with smart sash options (double pane outside, blinds inside and then a third removable pane). I got my cleaning solution, hose and dry rags ready.
I got through a few windows no problem but then I got to one where I noticed water was getting in behind the double pane (not between the glass but rather into the area holding the blinds). I carried on and the same thing happened on two other windows. All told, 3 out of the 10 windows I washed let water in.
I found this surprising because I haven't completed the replacement of my windows yet. I have the original windows on the rest of the house and they are probably the worst windows ever created by man. Yet, only one of those (out of 6 total) let water in.
I called the Pella service line and their response was that I shouldn't use a hose to wash my windows as they are not designed to be hit by water under pressure. I asked the rep what would happen in a rain storm with driving rain?
I can't begin to tell you how disappointed I am because when I dropped the large amount of money on what I thought were some of the best windows I could buy, I thought I was getting a top quality window. As it turns out they are no better at holding water out than 18 year old builder grade windows.
If you're still reading have you heard of this "don't use a hose" to wash outside windows?
Any thoughts would be appreciated>
