Complete the EPA’s Renovation, Repair and Painting (RRP) program. As of 2010, all painting contractors in the United States must be officially certified to work with lead-based paints.

Tally this by multiplying in feet the wall’s height by its width, minus windows and doors.” Determine how much paint is needed to complete the project. “To calculate the cost of a project, factor in the day rates, the size of the property, any architectural features, and the paint finish needed,” says Rance.
