I am knee-deep in my first home renovation. My latest project was to replace all of the trim—around the doors, floors, and windows—which, while labor intensive, sounded to me like a simple enough project. After ripping out the old stuff, I found that my seemingly well-installed floors were anything but. The floor was inches away from the wall, and none of our doorjambs were actually connected to anything. I thought I had one big job ahead of me, but it turned out I had three. Whoever did the work the first time took the easy route, leaving me with extra work.
