6. Stick around when you call in a pro
Part of being a good DIYer is knowing your limits. When you're struggling to figure out a tricky fix for a nagging problem, hiring a pro with years of experience will almost certainly save you time and money in the long run. Watch a pro tackle the trouble spot, and you'll learn a thing or two, as do the homeowners who receive a visit from the Ask This Old House team. During the debut season in 2002, the Ask crew (opposite, bottom right) helped homeowners with a variety of tasks that included fixing window screens, shoring up a sagging floor, and repairing a leaky shower-tub faucet.
