Categories Of Water Damage

Water damage can be a distressing experience for homeowners, but not all water is the same when it comes to the potential risks it poses. Restoration professionals categorize water damage into three distinct categories. Knowing the differences between categories of water damage is crucial for effective restoration and ensuring the safety of occupants.

Category 1: Clean Water

Clean water is water that originates from a source that does not pose a substantial risk to humans. This category includes clean water sources such as supply pipes and overflowing sinks. Clean water does not contain significant contaminants or additives and is considered the least hazardous category of water damage. However, it is important to address clean water damage promptly to prevent the growth of mould or other secondary issues.

Category 1 water damage typically poses the least risk to both property and occupants. The good news is that most materials affected by Category 1 water can be saved through proper restoration methods. However, it’s important to note that laminate, a type of flooring, is particularly susceptible to swelling and warping when exposed to water and in many cases cannot be saved

Category 2: Gray Water

Grey water contains a significant level of contamination and has the potential to cause discomfort or sickness if consumed or exposed to people. This category includes water from sources such as dishwasher and washing machine overflow, as well as sump pump failures. Grey water may carry microorganisms and nutrients that can promote the growth of bacteria or fungi. Proper precautions and thorough cleaning and disinfection are necessary when dealing with grey water damage.

While many materials affected by Category 2 water damage can be salvaged, there are exceptions to keep in mind. Carpet pads are particularly susceptible to absorbing and retaining moisture, making them challenging to effectively clean and restore. In most cases, these materials will need to be replaced to ensure a safe environment.

Category 3: Black Water

Black water is the most hazardous category of water damage. It is grossly contaminated and may contain pathogenic, toxigenic, biological, or other hazardous agents. This category includes water from sewage backups, floodwaters, or water containing human or animal waste. Black water poses significant health risks and requires professional expertise and specialized equipment for safe cleanup and restoration. If you are experiencing a water loss involving black water, please contact a Restoration Professional immediately.

In cases of Category 3 water damage, all materials involved are typically required to be removed due to the high level of contamination and potential health risks. If your interested in learning more about the steps of dealing with a flood, see Steps for Handling a Water Loss.
