Not necessarily. When establishing containment for an exterior renovation on a multi-story building, you must close all doors and windows within 20 feet of the renovation on the same floor as the renovation, and close all doors and windows on all floors below that are the same horizontal distance from the renovation. In certain situations, the renovation firm must take extra precautions in containing the work area to ensure that dust and debris from the renovation does not contaminate other areas of the property. The conditions at your renovation site may be such that closing and sealing doors and windows on floors above the renovation is necessary to prevent these areas from being contaminated by dust and debris.
