That was my husband's motto when we purchased our 40-year old house. We had become adept at ripping up old carpets, painting walls and doors, and had even replaced our wood deck all by ourselves, so we were feeling pretty confident about our abilities to care for and maintain our home.
We did respect our limits however. Truth be told, we're not really do-it-yourselfers, and since I'm an interior designer, I have a healthy understanding of what DIY-gone-wrong looks like, so I know when to stop and say let me call so-and-so. [ . . . ]
