I just laugh when people complain about the "terrible" windows they've got on their house. I win the pity party, every time.
The top window pictured to the left is one of the two windows on our stair landing. The grey gook you see is dusty silicone caulk, which is what is holding the glass in the frame. The upper sash rail is held in place by virtue of having been screwed tight to the top of the lower sash. This is the window that had a 2" open gap when when we moved into the house. The glazing compound had long since fallen off, and the glass had slid down the frame, following the rotted sash rail, leaving a large gap at the top which no one had attempted to fix. In fact, in our first year here, that rail actually fell off the window and down to the ground.
The lower picture is the window behind our headboard. What you see is my entire finger stuck into the space between the sash and the side jamb. At some point, the sash was replaced, but it was replaced by the whiz-bang maintenance people at the church who owned the house with a sash that is about 1" too narrow. I can almost pull the sash out of the frame without removing any trim. Because of how loose it is, it clatters and bangs in the wind. Fun stuff. We'll likely caulk it shut this winter.
I know you're wondering something, though. "Why on earth haven't you replaced the windows already?" Because we want to replace the entire window, not just the sashes. And that's expensive. Very expensive. What's sold as "replacement windows" is often simply a sash replacement set. That doesn't do anything for rotted frames or for all the empty, uninsulated space that's within the frame of an 89-year-old window. (The channels where the sash cords and weights hang, for starters.) To replace the entire window, we have to take the 60's era steel siding off, and we're not ready to do that and re-paint the clapboards yet. We can't do it ourselves at the moment, and we can't afford to pay someone, either. So we wait.
Meanwhile, I've got the trump card when people start complaining about the "bad windows" in their house. Bwahahahaha!
