Beautify Your Home With Crown Molding and Other Trim Upgrades

Crown molding makes it to the top of most remodeling lists because it adds charm and value to a home—not necessarily because people enjoy spending an entire Saturday try­ing to get the corners just right. Want a quick fix? 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.
