Do you ever stop to consider what’s behind your walls? No, I’m not talking about spiders, bugs or ghosts… I’m talking about all of the “stuff” that has to work in order for your house to function well. I don’t think about it much either — until recently. I began the process of finishing my basement. I’ve never really backed away from home improvements, and I gain a great amount of pride for building “sweat equity.” My will to see a project through, coupled with what some would call uber-thriftiness, lead me down the path to performing this task on my own.
