Can I control mold growth in a building?

Yes you can.  Dry out the structure and fix any moisture problems. Stop water leaks, repair leaky roofs and plumbing. Keep water away from concrete slabs and basement walls.  Open windows and doors to increase air flow, especially along the inside of exterior walls. Use a fan if there are no windows available.

Clean and dry water damaged materials within 24 to 48 hours, or consider removing and replacing damaged material. Mold growth normally starts within 72 hours after an organic building material has become wet.
