As you probably imagine, the Web will make home remodeling and even routine maintenance and repair easier. In one evening you can get an estimate on remodeling your kitchen, create a list of designers and contractors to do the job, price cabinets and appliances, order catalogs and check out loan rates to bankroll the project. You can even learn how to caulk a bathtub or power wash a deck. All while wearing your pajamas. But with all that the Web offers, it still can't do some things completely. And it does others poorly. Our road map to remodeling on the Web will lay out its strengths and weakness to keep you from wasting time on wrong turns and dead ends.
