There was a time many years ago that as a homeowner I would have called to have this work done. The idea of taking on a task like this was, for some reason, beyond my belief that I could accomplish such a task. In fact, as I look around the house, I can point to so many things--so many tasks--for which I have paid a contractor. For what? In hindsight: fear.
Recently I had the pleasure of installing a new TV mount from Echo Gear. Ordered from Amazon, unboxed and installed--single handed. There's some labor (the mount is not light), but the end result (and the feeling of accomplishment) worth every drop of sweat.
