Salt Lake City Mold & Water Damage Restoration — Mold or Water Damage in Salt Lake City? Get It Fixed Fast

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.

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.

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.

Both are barriers that keep surface floodwater away from a building. A berm is built of dirt or soil and must maintain a 3:1 slope (three horizontal feet for every vertical foot), which means planning on an area at least six feet wide for each foot of height; it must be grass-covered and free of trees because roots create leak pathways. A floodwall is a structural barrier built from concrete or steel and should be placed as far from the building as practical to reduce seepage and hydrostatic pressure on the foundation.
