If you have an old house, then you should own this book. Perhaps you don't want to tackle the problems of owning an old house yourself, but hire out instead. If that's true you should still read this book. You'll be more informed and know what the repairs might entail and what questions to ask your contractor. I use this book as a guide for my own repairs and its been invaluable. Simple, clear illustrations of what's inside the walls of an old home is very handy!
