cost for exterior house painting
1 Exterior paint averages $25-$40 a gallon, and a 3,000-square-foot home takes 15 or more gallons of paint, or $375-$600 just for the paint. However, it's possible to paint a large, two-story house for materials-only costs of $400-$600. 2  When hiring a painting contractor, paint and supplies make up about 15-25 percent of the cost, while 75-85 percent goes for labor.
