IICRC - Water Damage
Water damage can be deceptive. Water penetrates into structural cavities creating trapped pockets of saturation. The detection of water in these areas can often only be discovered with sophisticated moisture detection meters. Undetected moisture will continue to cause damage. This damage, at a minimum, will cause odors. Greater damage will surface when materials delaminate, shrink, split and further deteriorate to where costly repairs are required.
More than just removing excess water, IICRC-certified restorers have the knowledge and equipment to further dry a home or facility (including substructure materials) completely back to preloss conditions. Through timely response and the careful monitoring of water damage, mold and other issues can be prevented. If water damage has been present too long, mold will occur.
All IICRC-certified professionals have the training and experience to identify moisture sources, evaluate mold growth (visible or suspected), contain damage, remove contamination, and dry materials to ensure that mold will not return.
