All windows in house are aluminum double-glazed and are leaking (i.e. sweating)BETWEEN the glazing. Is there any fix without replacing all of them? I have 3 double crank-out, 3 single crank-out, and 4 sliding patio-type doors. House was built approx. 20 years ago. All windows are in very good shape except for the mess on the inside of them.

If the windows ever dry out, and are completely clean on the outside, you could try sealing the outer glass to the metal again with a product you can buy (don't know the name) at most hardware stores - made for that purpose. Read labels & make sure it's for glass to metal vs. wood.
This is called a seal failure, and is common in aluminum windows. You will need to find a glass company and get a quote on replacing all the insulating glass units. Then get a quote on new windows, might not be too much more, and vinyl windows would be a HUGE improvement to your current ones.
Good Luck!
I can relate to this! We had a 4'x6' bay window that fogged up between the glass. I tried to find cracks in the seal around the perimeter and applied glue, but that didn't work. I finally gave in and spent the money to replace the window for $350, including 10 year warranty. We are so happy with our new window now and glad we spent the money. I recommend getting an estimate from your local glass company. They should be able to replace the glass but not the frame. Check it out... it may not be as expensive as you think and you could be very happy. TK
