Is interior containment required as well as exterior containment for an exterior window removal?
Yes, if exterior window removal creates dust and debris on the interior of the building. Before beginning the renovation, the firm must isolate the work area so that no dust or debris leaves the work area while the renovation is being performed. If removing windows from the exterior creates dust and debris on the interior as well as the exterior of the building, then the firm must follow the requirements in the Renovation, Repair, and Painting Rule for both interior and exterior containment. Window replacement typically disturbs paint on both the interior and exterior of a building.
