Crown molding makes it to the top of most remodeling lists because it adds charm and value to a home, not because people enjoy spending a Saturday try¬≠ing to get the corners just right. Luckily, there's a simple way to beat miter-saw frustration. Trimroc molding from Canamould Extrusions is a lightweight polystyrene foam coated in hard plaster. It cuts smoothly with a handsaw, and, as This Old House senior technical editor Mark Powers shows here, it goes up in a flash with joint compound. No coping, no tricky angles, and ragged joints disappear with a dab of mud. So in just a weekend, you can upgrade a plain room to an elegant space—and still leave plenty of time for the rest of your list.
