The short answer

Stop the Water and Ensure Safety

First, shut off the main water valve if the flood came from a burst pipe. If the flooding is from weather or groundwater, you may need to wait until it is safe to enter. Turn off electricity to the affected areas before stepping into standing water, as water conducts electricity and can cause serious injury.

Wear rubber boots, gloves, and a mask to protect yourself from contaminated water. Floodwater may contain sewage, chemicals, or debris. If you feel unwell or notice strong odors, leave the area and see a doctor if needed. Your safety comes before saving any items.

Remove Standing Water Quickly

Use pumps, wet vacuums, or mops to remove as much water as possible. The longer water sits, the more damage it does to floors, walls, and stored goods. Open doors and windows to let air circulate, and run fans or dehumidifiers to speed up drying.

Move undamaged items to a dry area, and set aside anything that is wet but salvageable. Do not throw away items until you have documented them for your insurance claim. Take photos or videos of the flooded areas and the items before cleanup begins.

  • Shut off power before entering
  • Wear protective gear
  • Use pumps or wet vacuums
  • Open windows and doors
  • Run fans and dehumidifiers
  • Document everything with photos

Sort and Salvage Warehouse Contents

Sort through your inventory and equipment to decide what can be saved and what must be discarded. Porous materials like cardboard, insulation, and some upholstered items may need to be thrown away because they absorb water and can grow mold. Non-porous items like metal shelves and plastic bins can often be cleaned and reused.

For electronics, do not turn them on until they are completely dry and inspected by a professional. Water damage can cause short circuits and permanent failure. Similarly, valuable artwork or antiques may require specialized drying techniques. For these items, consider contacting a professional who handles electronics restoration or artwork restoration.

Dry and Clean the Structure

After removing water, dry out the building as thoroughly as possible. Use industrial dehumidifiers and air movers to reduce moisture in walls, floors, and ceilings. Remove wet drywall and insulation if they are saturated, as they can harbor mold and weaken the structure. Clean all surfaces with a disinfectant to kill bacteria and prevent mold growth.

Check for hidden moisture in areas like wall cavities and under flooring. Moisture meters can help you find damp spots that are not visible. If the flooding was severe, you may need to replace parts of the building materials. The pros can handle this level of drying and structural repair, but you can start the process immediately.

Document for Insurance and Plan Next Steps

Keep a detailed inventory of all damaged items, including descriptions, approximate age, and condition. This documentation helps your insurance claim. Policies vary, and your insurer decides what is covered. Contact your insurance company as soon as possible to report the flood and ask about the claims process.

After the initial cleanup, you may need to arrange for professional restoration of the building and its contents. The pros can handle large-scale drying, mold remediation, and repairs. For a warehouse, this might involve coordinating with multiple trades, such as electricians to check wiring and plumbers to repair pipes. If you live in Detroit, keep your shutoff valve location written down for future emergencies.

Frequently asked questions

What should I do first after a warehouse flood?

Stop the water source if you can, then turn off power to the affected area. Wear protective gear and document the damage with photos. Remove as much standing water as possible to limit further damage.

Can I save wet cardboard boxes and paper goods?

Usually not. Cardboard and paper absorb water and can grow mold quickly. It is safer to discard them and focus on saving non-porous items. For important documents, you may need professional drying services.

How long does it take to dry a flooded warehouse?

Drying time varies based on the extent of flooding, materials, and ventilation. It can take days to weeks. Using industrial dehumidifiers and air movers speeds up the process. The pros can assess and manage the timeline.
