Staining a deck costs $540 to $1,000. Covered porches might hit $2,000. Consider negotiating the price a bit lower by combining it with a full exterior job. Painting handrails can run anywhere from $1 to $2 per linear foot, depending on whether it’s wood, metal or some other material. Although you might think this is an easy $30 to $100 job, most painters charge a minimum fee regardless of the size of the project. You’ll probably end up paying at least $150.
