| Animated Images |
The image library contains mold-related images in seven categories. There are also animated images that you can choose to view and download. Each photo has a larger, higher resolution version. To download a higher resolution version of a photo, click on the thumbnail. When the window opens, right click and choose whether you want to copy or print the photo. If copying, paste the photo into a photo-editor program or presentation.
These photos may be used for presentations and educational purposes without contacting EPA — please see EPA's Privacy and Security Notice for more information.

 Water stains in basement. (photo courtesy of Terry Brennan) |
 Water-damaged ceiling tiles. Air conditioning ducts above the ceiling were not insulated in several areas resulting in condensation on the ducts that dripped onto the ceiling tiles. (photo courtesy of Terry Brennan) |
 Puddles on flat roof. |
 Wood showing water stains caused by roof leak. |
 Water from roof leak has seeped into a wall causing the paint to buckle and peel. (photo courtesy of Terry Brennan) |
 When built, the roof had a hole for the drainpipe; however, a drainpipe was not installed until years later. The white stains on the brick are mineral deposits resulting from rain pouring through the drain hole onto the walls. (photo courtesy of Terry Brennan) |
 In this case, the icicles result from warm air in the house leaking into an attic without sufficient insulation. (photo courtesy of Terry Brennan) |
 Several inches of water in a basement with a broken sump pump. (photo courtesy of Terry Brennan) |
 Water in the ground has seeped through the concrete walls of the basement, leaving white mineral deposits on the walls. The water has evaporated into this basement, increasing humidity. Mold is growing in some areas. (photo courtesy of John Martyny, Ph.D.) |
 Mineral deposits on the surface of a dirt crawl space caused by chronic water problems. (This is not mold.) (photo courtesy of John Martyny, Ph.D.) |
 Flooding. EPA mold guidance is not for flood water. |
