Water damage from leak
As a result of frozen pipes bursting, we experienced severe water damage at my job. Professionals came in and did the clean up, which included opening walls to check for moisture, etc. Now weeks later, there is a strong mold and/or mildew smell from a small area in which much water came down. Since walls were opened and inspected and now everything is painted and repaired, what would next step be in finding out what is causing the odor? Also, could paper that had been wet, cause such odors?
