Mark Curry sees the garage as home improvement's new frontier. Which is why, six months ago, he launched Those Garage Guys, a company marketing a modular system for bringing order to chaos. Garages, Curry says, are "the biggest junk drawer in the house." His system can turn 400 feet of garage into a neatly arranged space with hooks, shelves, baskets, and cabinets for around $6,200. Add flooring, and it's about $10,000.
