Common questions about water damage in McKinney, TX.
what should be thrown away after flood water touches it?+
Porous materials that absorbed floodwater harbor deep-seated pathogens and should be discarded rather than dried: drywall and gypsum wallboard, carpeting, upholstered furniture, mattresses, and books. Hard surfaces such as concrete, metal, and certain plastics can be stripped, cleaned, and disinfected. Materials soaked by Category 3 water are typically unsalvageable regardless of type.
what is the iicrc s500 standard for water damage restoration?+
The IICRC S500 Standard for Professional Water Damage Restoration is the baseline technical expectation for drying and decontaminating a building. It defines the water categories (clean, gray, black), the drying standards materials must reach (per manufacturer specifications), and the professional documentation expected, including moisture mapping and psychrometric data logs. Demand that any restoration contractor explicitly follows it.
what is the 50 percent rule for flood repairs?+
The "Substantial Improvement" or 50% rule says that if the cost of an addition, repair, or reconstruction project equals or exceeds 50% of the value of the existing building, the entire structure must be treated as new construction and brought to or above the Base Flood Elevation. In many jurisdictions improvements are cumulative, so several small projects over the years can eventually trigger the mandatory elevation requirement.
are there specific building materials recommended for wet floodproofing?+
Yes — replace structural components below the flood level with materials that resist water damage. Concrete blocks should replace wooden studs and gypsum wallboard; metal and glass are preferred because they can be salvaged and disinfected after contact with black water. Permanently raise heavy utilities such as furnaces, water heaters, and laundry equipment above the expected flood level, and treat any remaining wood with a borate supplement before re-hanging wall coverings. Foundation vents must also be installed so floodwaters enter and exit at the same rate, equalizing pressure and preventing structural collapse.
