Have you ever heard of a company that has a process where they install a filter of some kind to your window to allow the moisture to come out and never come back. I have moisture in a few windows and if I can get away with not changing the windows, so much the better.
Answer:
I try very hard to stay away from comparing companies or services but I know that your problem has be very well looked after by adhering to the following: In some cases windows have lost their thermal seals. If there are certain gasses in a particular unit and the seal has been gone for some time, streaks may be quite permanent. If, on the other hand, the seal depends on a vacuum, it can often be corrected without having to replace the complete unit. Rather, by removing the window and drilling 3/16” holes along the top down through the frame and metal spacer between the sheets of glass. Now turn the window over and do the same thing along the bottom. The holes are 3 to 4 inches in from the ends. You can then re-install the window and drill the same sized holes in the frame horizontally from the outside to meet the vertical ones. The latter should be sloped slightly upward and all you have to do from there is fill them with non-corroding steel wool. This will permit air to pass but insects won’t get in.
