Takes awhile but that's how almost of us have done it. 20 years ago I barely knew how to use a wrench. Now the only thing I'm afraid of in the house is the main electrical lugs coming into the breaker panel. Beyond that, it's pretty easy if you're willing to sit, scratch your head, search YouTube, and solve the problem.

Houses and their problems are stupid simple, especially if you're ripping out and starting over.
