Flood Damage Restoration

The IICRC S500 standard defines three contamination categories: Category 1 (clean water) comes from sanitary sources — supply line breaks, tub overflows, appliance failures with clean water. Category 2 (gray water) carries significant contamination and can cause illness if ingested — dishwasher overflow, toilet overflow (urine only), washing machine discharge. Category 3 (black water) is grossly contaminated and poses serious health risk — sewage backups, flooding from rivers and canals, stormwater flooding, and seawater. Category 3 requires full containment, PPE, and demolition of all affected porous materials.

Yes. Storm surge and hurricane flooding is classified as Category 3 (black water) under the IICRC S500 standard because floodwater from external sources carries sewage, agricultural runoff, animal waste, and chemical contaminants regardless of its visual appearance. All porous materials (drywall, insulation, flooring, carpet) that contact Category 3 water must be removed rather than dried in place. The work environment must be contained and maintained under negative air pressure with HEPA filtration to protect workers and unaffected areas.

IICRC S500 defines four moisture classes based on the amount of water absorption and the materials affected. Class 1 (least) involves minimal absorption — only part of a room affected. Class 2 involves the entire room with water absorbed into carpet and lower walls. Class 3 involves water absorbed into walls above the "24-inch line" (ceiling, upper walls, insulation). Class 4 involves deeply-held moisture in materials like hardwood, plaster, concrete, or masonry that require specialty drying equipment and extended drying times. Florida's humidity means Class 4 conditions develop faster than in drier climates.

Our technicians document all flood damage in formats accepted by FEMA individual assistance programs, NFIP adjusters, and private insurance carriers: moisture readings at every affected surface using Delmhorst meters, FLIR thermal imaging for hidden moisture, photo inventory of all structural and contents damage, written IICRC category and class determination, and a complete Xactimate-formatted scope of mitigation work. We communicate directly with your adjuster and can provide supplement documentation when initial claim estimates are inadequate.
