How do I measure for a window replacement that was installed from the outside?
My windows were installed from the outside and the siding was installed over it. I have already replaced one window, but my measurements were wrong making the window too small. I had to frame out the window to make it fit. Of course, after the window was in, I installed trim around the outside window to hide where I cut the siding away. It looks nice, but I don't want to frame all the other windows. All the instructions on the Internet are for windows with sashes or windows installed from the inside. Thanks for any guidance anyone might provide!
