Ok as I move more into what started as a simple roofing job. which now has become a re-side and most likely a window update/replacement job. If this was not Michigan and I could sell my house I think I might, but since you can't give a house away in Michigan I think I will get to my question. I picked up an Anderson catalog at a local lumber yard today that is a Anderson dealer and found a Narrow line conversion kit in it. I called Anderson and they tell me that I have Narrow line windows from 1992 and these kits are available for my windows. My question is has anyone ever done this? Are they more expensive than just swapping out the whole unit, is it a DIY project anything else about them you know. I really would like to at least get my 2nd story windows into tilt window so we don't have a to climb a ladder to wash them anymore. I am not as concerned about my 1st floor as they can be cleaned easier. I love owing a home. Maybe a big blue tarp over it would be faster cheaper and less headaches until the wind blew
