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.

Gallery 4: Prevention
 Moisture issue: Foundation is wet; drain gutters are too short. Fix: Drain rain water away from the house, generally about 5 feet away from the foundation. Gutters below grade (below the soil) are protected from damage, while those above grade may be more easily damaged. (photo courtesy of Terry Brennan) |
 Moisture issue: Rainwater is falling and collecting near the foundation of this house. Fix: It is important that the water drain away from the foundation—the ground could be sloped away from the foundation so that the water will run off. (photo courtesy of Terry Brennan) |
 Moisture issue: Disconnected downspout deposits rainwater from roof onto walls and near foundation. Fix: Connect the 2 downspouts. (photo courtesy of Terry Brennan) |
 Moisture Issue: A lawn sprinkler is located near the outside wall of a building; the sprinkler sprays the wall directly, and water leaks through wall into the building. Fix: Move the sprinkler away from the building so that water does not wet the walls or collect near the foundation. (photo courtesy of Terry Brennan) |
 Moisture Issue: Foundation was chronically wet, water and mold damage was found on original structure. Fix: Area was regraded during construction of an addition so that water drains away from the foundation. |
 An example of window flashing, applied so that water drains to the outside of the window and not into the surrounding frame or walls. (photo courtesy of Terry Brennan) |
 Rust is an indication that condensation occurs on this drainpipe. The pipe should be insulated to prevent condensation. |
 Moisture issue: Condensation on uninsulated air conditioning duct. Fix: Insulate the duct on the outside. (photo courtesy of Terry Brennan) |
 Moisture issue: Leaking pipes. The leaking pipes under the kitchen sink were taped; the pipes continued to leak, and the area got moldy. Fix: The pipes should be fixed by a plumber or other qualified professional. (photo courtesy of Terry Brennan) |
 Example of a drain pan beneath a cooling coil that slopes to a drain line and is constructed of stainless steel. (photo courtesy of Terry Brennan) |
 Example of a crawlspace without mold or water problems. The site is well drained. The crawlspace has a vapor barrier over the earth, is air-sealed, and insulated on the walls. (photo courtesy of Terry Brennan) |
 Two examples of dehumidifiers. For spaces that are damp, often at high humidity, but do not have liquid water running through them, a dehumidifier can be used to reduce humidity. (photo courtesy of Terry Brennan) |
 Example of exhaust vent in a bathroom. (photo courtesy of Terry Brennan) |
 Example of an exhaust hood and fan over a stovetop in a kitchen. An exhaust fan over a range draws heat, moisture, and contaminants out of the house. Range hoods should vent to the outside. (photo courtesy of Terry Brennan) |
