Too bad a house doesn’t come with an owner’s manual. And a week-long seminar where you learn what every button, switch, and wire is for. Alas, the keys to the castle come with no troubleshooting guide to dog-ear—and, we’re betting, no wise master to unlock the mysteries of the place you call home.

Then again, that’s what we’re here for: to provide fast fix-it advice when it’s time for you to do your homeowning duty. Because at some point, you’re going to have to know how to change out a light fixture without zapping yourself to kingdom come. Or paint a double-hung without gumming up the works. Or stem the flood when the toilet overflows. And you’re going to want to do things right. The first time.
