Before entering a building where flood damage may have occurred, make sure it’s safe: check for electrical hazards and structural damage, and use proper protective gear like boots, gloves, and respirators. Before you start any construction or repairs, check for common hazardous materials like lead paint and asbestos, which may require help from professional and State-licensed contractors.
Then, follow these tips:
The severity of damage escalates the longer water sits and building components and contents stay wet, so time is of the essence in the aftermath of a flood. In fact, mold will grow within 48-72 hours, so aim to start removing water and drying the environment within 48 hours. Have a list of professionals on hand to call, and understand your insurance policy, as some only cover mold damage up to a certain amount, while others don’t provide any reimbursement for mold.
Ventilate affected areas to prevent mold growth
Mold loves moisture and organic materials such as paper or particleboard. In order to mitigate or slow damage, open windows if weather permits and place fans inside of them to keep air moving and maintain moderate temperatures. Work toward the fan as you clean to minimize cross-contamination.
Assess damage to items and materials
Assess the type of water absorbed by items, such as rainwater, water from broken pipes, contaminated river water, or bacteria-filled sewage. There are ways to salvage specialty items but the decision on whether to save or trash an item will vary depending on the dollar and sentimental value to the owner. It may not be worthwhile to salvage drywall, carpets, pads, mattresses, pillows, box springs, and particleboard.
On the other hand, it might be worthwhile to restore costly Persian rugs, leather couches, and antiques or heirlooms. Wet clothing and many household fabrics may be salvageable through machine washing, and a 10-minute soak in detergent and hot water, to remove contamination and stains. The IICRC strongly recommends that in water damages where there are contaminants present (e.g., bacteria, sewage, mold) or where small children or immune-compromised individuals are present that an inspection is conducted by an appropriately trained restorer and remediator.
Expose pockets of saturation
Hidden and concealed pockets of saturation need to be opened for cleaning and drying. Layers between building materials hold water that must be discovered and removed or dried. On walls, find the water line and inspect at least a foot beyond it to make sure all damage, wet materials, and mold are discovered. Remove and discard the damaged drywall and wet wall insulation.
Wet carpets can usually be dried by professionals with the right equipment, but carpet padding, which is like a big sponge, should be discarded. Wood base trim and hardwood can also be saved with the right equipment if they can be accessed and completely dried on both sides. Remember to investigate concealed cavities such as behind walls, in mechanical spaces, under cabinets and furniture, and in crawl spaces.
Conduct a thorough cleaning
Durable, non-porous, or semi-porous materials, such as studs and joists, hardwood flooring, and vinyl products, can be cleaned with common cleaning products or specialized products with detergents. During cleaning, take care to protect areas that are unaffected by the water or mold. After a thorough cleaning of salvageable materials, a disinfectant solution may need to be applied in case of harmful bacteria from sewage, river water debris, or even standing water that has gone bad.
Professionals like water restoration and mold remediation contractors and indoor environmental professionals can help you decide what is best for your situation. Once you’ve cleaned the wet materials, conduct another round of cleaning. If you choose to vacuum, use a HEPA-filter vacuum to remove allergens, fine dust, and spores.
Confirm drying before reconstruction
In order to prevent dry rot and structural damage, it’s important not to reconstruct or cover wood and other wet materials until the moisture content has been adequately reduced. A water restoration professional can confirm proper drying before reconstruction.
