We are working on a project to replace most of the windows in a custom home. These windows are double-glazed and wood-framed. Reason for the replacement is condensation between the window panes. We have found to our dismay that the builder, or whoever, had installed these windows to the wood frame with liquid nail. It is near impossible to remove the outside wood stoppers without damaging them. It is but impossible to get the old windows out of their wood frames the traditional way. There has to be a method of softening the liquid nail which is bonding the window to its frame prior to removing the glass. What is the best chemical solution to use? We need something that is liquid enough to penetrate inside the frame. We believe this problem has been dealt with before. Any pointers? Thank you in advance for your help.

So this past Winter we had the idea to use a clear silicone caulk to seal a few drafty windows. I just now realized that we used the wrong kind. We thought we had used the kind that simply peels right off when pulled, but instead it's more of a permanent caulk! I've been trying for the past hour to razor it and peel it, but it's not going too well. Is there any thinner-type product (like Goop-Off) that I can spray it with to help get it off? The house is being repainted next month, so I'm not too worried about the paint. I just don't want to keep gouging the wood with my razor.
