While Steckel says that painter’s tape isn’t always necessary, it can be helpful, especially if you’re unsure about the steadiness of your hand. When painting the baseboard, for example, apply tape along the edge of the wall and the floor to ensure a clean line. If you’re hiring a pro, keep in mind that intricate details could make the project more expensive. “Baseboards, casings, crown moldings, wainscoting, windows, and rails all require extra time to be painted, which in turn will increase interior painting spend,” he explains. “Painters will charge for additional tape, contrast or matching paint, and materials needed to paint extra trim.” But for a stylish effect, you’ll want to live with for years, the project may be well worth the extra effort and expense.
