The cost of an exterior paint job varies based on factors like the size of your home and the quality of paint used. On average, it can range from a few thousand to several thousand of dollars. The average single-story, 2,000 square-foot home can be completely covered with two coats by using six gallons of paint, which costs around $20-$90 depending on brand, type, and quality. Labor for painting usually costs between $20-$60 an hour.
